Definitions
- the present invention is related to interfaces for large scale presentation systems and more specifically to interface features that enable conference attendees to readily and intuitively share information within a conference space and/or remotely.
- conferencing systems at least some of which include a master presentation unit and one or more slave presentation units that can be set up within a conference space (i.e., a conference room) for sharing information.
- the master unit includes a large scale flat panel display, a sensor system and a display processor.
- the processor presents information via the display such as interfaces for software applications, pictures, video, electronic whiteboard images, etc.
- the processor is linked to the sensor system for receiving information indicative of user activity adjacent/on the display screen and for performing functions associated with the received information and the nature of the activity. For example, where a system operator (i.e., a conference presenter) uses a mechanical stylus as a pen device to draw on the screen, the processor may be programmed to provide virtual ink markings that follow movements of the stylus tip.
- an application interface is provided on the screen that includes selectable button icons, the processor may be programmed to sense when the stylus is used to contact the screen at a location corresponding to the button icon and may then cause an activity associated with selection of the icon to be performed.
- the slave presentation units are also large scale units that include some type of presentation surface that is typically as large or larger than the master unit display screen.
- the slave units are meant to be positioned adjacent the master unit for viewing by persons within the conferencing space.
- a master unit operator can use the master unit to indicate that information presented via the master unit should be presented via one of the slave units.
- the master unit information is so displayed.
- the master-slave system is, in at least some respects, akin to a conventional paper based flip chart where the master unit is useable to create and modify images and the slave units are usable to display images of interest after the images are created.
- the slave units include one or more projectors, each projector projecting one or more slave images on a slave presentation surface.
- two or more master/slave subsystems can be linked via a network so that conference attendees in remote locations can all simultaneously view the same images.
- At lease one embodiment includes a method for configuring presentation units for cooperative activities, the method comprising the steps of providing a master presentation unit including a display and at least one input device in a conference space, providing a processor associated with the master presentation unit, moving a plurality of portable projectors within the conference space, associating the master presentation unit with at least a subset of the projectors within the conference space wherein the associated subset of projectors includes at least two projectors, presenting an image via the master presentation unit display, providing a control interface via the master presentation unit display for designating any one of the projectors from the associated subset that should display the image presented via the master presentation unit, and when a projector is designated to display the image from the master presentation unit, using the designated projector to project the image from the master presentation unit onto a presentation space within the conference space.
- the step of associating the master presentation unit with a subset of the projectors includes presenting a list of the projectors via the master presentation unit display and receiving selections designating the subset of projectors via the master presentation unit input device.
- Some embodiments further include the step of providing a sensor system for determining which projectors are in the conference space.
- each of the projectors includes an identification tag and wherein the sensor system includes at least a first tag reader for reading the identification tag.
- the ID tag is an RF ID tag and the sensor is an RF sensor.
- the step of providing a plurality of projectors in the conference space includes providing projectors that each include a wireless transmitter, the step of associating further includes the step of causing the projectors in the space to transmit unique projector identifiers to the master presentation unit, the step of presenting a list including presenting a list including a separate entry for each of the unique projector identifiers received by the master presentation unit.
- each of the projectors projects at least first and second images onto at least first and second presentation spaces, respectively, and wherein the step of providing a control interface includes providing an interface that facilitates designation of any of the first and second presentation spaces associated with any of the projectors.
- the step of providing a control interface includes providing an interface that enables designation of any of the images presented by any of the projectors to be represented by the master presentation unit via the master presentation unit display.
- the step of moving a plurality of projector units into the conference space includes providing each projector unit on a separate projector cart wherein each cart includes wheels to facilitate transport of the projector and moving the carts and projectors into the conference space.
- the step of associating the master presentation unit with a subset of the projectors includes mechanically linking each of the carts to the master presentation unit.
- the step of moving the carts includes arranging the carts in a side-by-side fashion and wherein the step of mechanically linking includes connecting communication cables between the master presentation unit and the projectors.
- the step of mechanically linking further includes connecting power cables between the mater presentation unit and the projectors.

- Memory 88 is a digital memory device and includes a plurality of different types of information usable by processor 80 to perform various methods. Generally, the information stored in memory 88 takes two forms including programs run by processor 80 and data such as images presented via display screen 48.

- memory 88 includes programs used to manage images present via display 48.
- a program in memory 88 may assign unique identifier numbers or the like to each image flipped from unit 28 to one of the slave presentation units and may store each flipped image and corresponding identifier number within memory 88 for subsequent access.
- the master unit processor 80 may be programmed to correlate and store the flipped image with a unit identifier that uniquely identifies the slave unit to which the image is being flipped. After an identifier and an image is stored in memory 88, the image may be accessed via reference to the unique identifier.

- software applications such as PowerPoint, spreadsheets and the like may be stored in or accessed via a palm or laptop type computer useable with master presentation unit 28 so that, while processor 80 is used to display images corresponding to conventional software applications, processor 80 itself does not run the software applications.
- control interface 30 may include various types of input devices.
- mechanical hardware type buttons like the keys illustrated in Fig. 2 may be provided within the front surface 53 of housing 52 for providing commands to processor 80 such as flip commands (i.e., commands that indicate that an image currently on display 48 should be transmitted to slave presentation units and then removed from display 48) and other data access and program control commands.
- touch selectable icons may be provided on display screen 48 for selection by a system operator which, when selected, provide command signals to processor 80 to perform processes.
- the input device 30 may include image augmentation capabilities (i.e., be in part an augment interface) so that marks can be added to an image on screen 48 or deleted.

- exemplary master unit keyboard keys include a resume key 56, a send or Flip key 58, a store key 60, a retrieve key 62, a left send key 68, a right send key 70, and a number pad 67.
- the selectable keys described and illustrated herein are only exemplary and, in many cases, additional selectable keys or a subset of the keys described herein may be provided via display 48, the selectable key set being dependent upon the functions supported by the system 10 and, in at least some cases, the relative juxtaposition of system components.
- master presentation unit 28 may be positioned to one side of the slave presentation units 22a, 22b, etc. relative to an audience viewing the units within room 1 1 . In this case, to flip an image from display 48 to one of the slave presentation units 22a, 22b, etc., there must be some way to specifically identify the slave unit to receive the flipped image.
- unique slave unit identifiers "1 " and “2" are provided on each one of the slave units 22a, 22b, etc., which are easily viewable by a system operator when the operator is in a position to facilitate collaborative activity by interacting with master unit 28.
- the unit identifiers "1 " and “2" are permanently printed at one end of each of the unit housing assemblies.
- processor 80 is programmed to monitor keyboard 30 for an indication that the image on display 48 is to be flipped to one of units 22a or 22b.
- processor 80 uses number 67 to select the unit identifier number corresponding to the unit to which the image is to be flipped and subsequently selects send key 58.
- the operator uses pad 67 to select number "1 " and then selects key 58.
- the operator selects number "2" from pad 67 and subsequently selects send key 58.
- each separately addressable slave units and also, in some embodiments, master unit 28, has a unique network address that can be used to send data thereto.
- slave units 22a and 22b may be assigned unique wireless addresses "XP45519784" and "QZ1433217", respectively, while master unit 28 is assigned address "AM7966142”.
- the addresses of slave screens are correlated with the unique salve unit identifiers (e.g., "1 " and "2" in the present example) and the correlated addresses and identifiers are stored in master unit memory 88.
- processors in each of the slave units 22a, 22b, etc. are programmed to monitor for and receive wireless signals sent to their respective network addresses.
- processor 80 When a slave unit is selected as a target for a flipped image, processor 80 identifies the network address associated with the target slave unit, generates an image data packet including the image and the address of the target slave unit, transmits the data packet to the selected slave unit and then, in at best some embodiments, erases the image from display 48 (i.e., blanks display 48) or otherwise renders the image un-observable via display 48 to provide a clean and clear surface 48 in a manner that mimics a conventional paper pad type flip chart. In other embodiments a second affirmative step may be required to render the master image un-observable.
- master presentation unit 28 is also useable to retrieve images presented via the slave presentation units 22a, 22b, etc., so that those images can be edited and then represented via the slave units in the edited form.
- the image data received by the slave unit is temporarily stored in a slave unit memory (see 1 19 in Fig. 5).
- the image when master unit 28 flips an image to a slave unit, the image may be correlated with and stored with the unique slave unit identifier in master unit memory 88. Thereafter, when an operator wants to represent a slave image via master unit 28 for editing or the like, the operator can select the appropriate slave unit identifier (i.e., the identifier number associated with the slave unit presenting the image to be re-accessed) via number pad 67 followed by retrieve key 62 causing processor 80 to access the previously stored image in memory 88 and present the image via display 48.
- the appropriate slave unit identifier i.e., the identifier number associated with the slave unit presenting the image to be re-accessed
- a function is provided whereby the operator can quickly store all of the images currently presented via the presentation units such that, upon resuming the presentation or collaborative activity, all of the currently presented images can be quickly and immediately re-presented via the presentation units in the same relative juxtapositions.
- processor 80 may be programmed to monitor store key 60 and, when icon 60 is selected, may correlate each of the unique presentation unit identifiers (e.g., "1 ", "2", etc., an identifier uniquely associated with master unit 28, etc.) with the image currently displayed by the corresponding presentation unit as an image-unit set and then to store the image-unit set in memory 88. Thereafter, to re-present the images via the master and slave units at a subsequent time, the operator may select resume key 56 after which processor 80 accesses the image-unit set and re-presents those images via the master and slave units.
- the unique presentation unit identifiers e.g., "1 ", "2", etc., an identifier uniquely associated with master unit 28, etc.
- processor 80 may be programmed to enable the operator to uniquely identify the image-unit set by providing a name therefore useable to recognize the specific image-unit set.
- more than one image-unit set may be stored in memory 88 and subsequently unambiguously retrieved to resume presentations.
- images may be stored with unit identifiers
- similar results can be achieved by storing images along with network addresses when store key 60 is selected.
- processor 80 simply accesses the stored images and addresses and flips the images to the correlated addresses without having to perform the intermediate step of correlating the unit identifiers and addresses.
- the number of slave units used with a master unit will not change and that keys dedicated to specific slave units and functions may be provided on keyboard 30.
- a system 10 only includes one master unit 28 and two slave units 22a and 22b, separate send and retrieve keys for each of the slave units 22a and 22b may be provided so that single key selection can cause image flipping/retrieving.
- a master unit 28 may be positioned between two slave units (i.e., master unit 28 and slave unit 22a would be swapped so that unit 28 is between slave units 22a and 22b).
- simple left and right send icons 68 and 70 may be used to flip images from master unit 28 to the slave units to the left and right of the master unit, respectively.
- simple left and right retrieve arrow icons similar to icons 68 and 70 may also be provided for retrieving images from the slave units to be re-presented via screen 48.

In any event, processor 1 10 controls printer 1 16 to provide a rendition of the image flipped to unit 22a from master unit 28. In some cases the rendition will be in color while in other cases it may be in black and white. In still other cases the user may have the option to print in color or in black and white.
- Eraser 1 18 is controlled by processor 1 10 to erase ink applied by printer 1 16 to presentation surface 48a. To this end, eraser 1 18 may simply move back and forth along the length of housing 100 while holding an eraser pad on surface 48a as screen spindle 1 14 rolls up screen 38a. In the alternative, processor 1 10 may be able to control eraser 1 18 to erase certain information from surface 48a while leaving other information on surface 48a.
- the modified image may be presented via unit 22a by erasing the appropriate information from surface 48a and unrolling screen 38a so that the modified image is viewable via surface 48a.
- the image data packet is transmitted via transceiver 22 to processor 1 10 via transceiver 34a after which processor 1 10 controls motor 1 12 and printer 1 16 to simultaneously unroll screen 38a and apply ink to surface 48a thereby forming the flipped image on surface 48a.
- processor 1 10 controls motor 1 12 and printer 1 16 to simultaneously unroll screen 38a and apply ink to surface 48a thereby forming the flipped image on surface 48a.
- processor 1 10 first controls motor 1 12 and eraser 1 18 to roll up screen 38a while simultaneously erasing the ink printed thereon.
- processor 1 10 next controls motor 1 12 and printer 1 16 to again apply ink to surface 48a thereby providing the newly flipped image on surface 48a for the audience to view.
- Fig. 1 it should be appreciated that the dimensions of the master display screen 48 and the portion of the slave screen 38a that is unrolled and used to present an image are similar such that an image flipped to and presented via screen 38a has a scale substantially similar to the scale of the image that was originally presented via display 48.
- Figs. 1 through 5 it should be appreciated that where the master and slave units 28 and 22a, 22b, etc., are removable from rail 40, the entire system described above can be easily transported from one conference room 1 1 to another and can easily be set up by placing the mounting members that extend from the rear surfaces of the units over a rail in the other conference room similar to rail 40. During transport, the screens (e.g., 38a) of the slave units can be completely rolled up for protection and to provide a compact configuration. [0148] Referring now to Fig.
- a second embodiment of a slave presentation unit 120 including a top header 122, a housing 124, a transceiver 130, a screen 126 and first and second mounting members 132 and 134, respectively.
- Mounting members 132 and 134 are similar in construction and operation to mounting members 102 and 104 described above and therefore will not be described here in detail.
- members 132 and 134 extend from a rear surface of header 122 for mounting unit 120 to a rail like rail 40 described above.
- screen 126 is rigidly secured to a lower surface of header 122 and lower housing 124 forms an opening (not illustrated) through which a distal lower end of screen 126 extends and in which a screen spindle similar to spindle 1 14 described above with respect to Fig. 5 is mounted.
- the processor 1 10, motor 1 12, printer 1 16, memory 1 19 and eraser 1 18 described above with respect to Fig. 5 are also mounted within housing 124 and transceiver 130 extends upwardly from housing 124.
- the image data packet transmitted is received via transceiver 130 and the processor in housing 124 simultaneously controls the motor and printer therein to unroll screen 126 and apply ink to surface 126 forming the flipped image thereon as housing 124 descends (see arrow 128) below header 122.
- An advantage here is that the image can be printed from top to bottom.
- the processor inside housing 124 simultaneously controls the motor and eraser in housing 124 to roll screen 126 up and erase ink from surface 126.
- each of the slave units includes a processor 1 10, a motor or motivator of some type 1 12, a printer 1 18, an eraser 1 16, a memory (not illustrated), mounting members (e.g., 104) and a transceiver 34a similar to those described above with respect to Fig. 5 and therefore, in the interest of simplifying this explanation, those components are not separately described again here.
- the primary difference between the embodiments of Figs. 7, 8 and 9 and the embodiment of Fig. 5 is in how the presentation screens are extended and retracted.
- the embodiment of Fig. 7 is generally a pull-out endless loop style unit and includes both a powered spindle 151 and a freewheeling spindle 148.
- Powered spindle 151 is driven by motor 1 12 under the control of processor 1 10.
- screen 144 is a continuous belt or loop type screen that wraps around powered spindle 151 within housing 100 and extends downward and wraps around freewheeling spindle 148 below housing 100 such that a front screen segment forms a front presentation surface 155 and a rear screen segment forms a rear surface 159 facing in a direction opposite the direction of surface 155.
- housing 100 forms two slit like openings 140 and 142 that extend generally along the entire length of housing 100 to allow screen 145 to pass therethrough.
- spindle 151 may be powered in either clockwise or counterclockwise direction so that screen 144 can move in either direction up or down as indicated by arrow 146 and so that freewheeling spindle 148 can rotate in either clockwise or counterclockwise directions as indicated by arrow 150.
- processor 1 10 controls the motor 1 12 and printer 1 16 simultaneously to apply ink and form the image on screen 144 as spindle 151 rotates in the clockwise direction. After an image is formed, the image is viewable on front surface 155 between housing 100 and freewheeling spindle 148.
- spindle 151 may be rotated in the counterclockwise direction while eraser 1 18 removes the ink from screen 144.
- spindle 151 may be rotated in the clockwise direction so that the image rotates about freewheeling spindle 148, back up toward and around powered spindle 151 and again down past eraser 1 18 while eraser 1 18 erases the ink on the screen.
- eraser 1 18 may be positioned on the opposite side of screen 144 within housing 100 and may be used to erase images presented thereto on screen 144 as section 155 is moved up through opening 140.
- exemplary slave presentation unit 173 is a pull-out drop loop style unit and includes a first powered spindle 163 and a second powered spindle 165, both mounted within housing 100, as well as a freewheeling spindle 167 wherein first and second ends of a presentation screen 181 are mounted to and rolled around spindles 163 and 165, respectively, and a central portion of screen 181 wraps around freewheeling spindle 167 that hangs below housing 100.
- the powered spindles 163 and 165 may be used to move a presentation surface 183 of screen 181 either upward or downward as indicated by arrow 146 and about spindle 167 in either direction as indicated by arrow 187.
- a printer 1 16 and an eraser 1 18 may be controlled to apply ink to the presentation surface or to remove ink therefrom to reflect image flipping activity caused by interaction with master unit 28.
- unit 175 is a pull-out accordion style unit similar to the units described above with respect to Figs. 5, 7 and 8 except that the spindles are replaced by a take up and let down assembly 174 and the screen, instead of being a reliable screen member, is a segmented accordion type screen 172 including elongated horizontal screen members, two of which are collectively identified by number 189, that are linked along horizontal elongated edges.
- motivator 1 12 is controlled by processor 1 10 to let out the screen 172 adjacent printer 1 16 and to take up the screen 172 adjacent eraser 1 18 as indicated by arrow 170.
- an exemplary HHD interface unit 200 includes a generally rectilinear and rigid plastic or metallic housing 199 that protects and supports other unit components including a processor 203, a display 204, a keyboard 209 and a transceiver 21 1.
- Processor 203 is linked to each of transceiver 21 1 , screen 204, memory 207 and keyboard 209 to receive information therefrom or provide information thereto, where appropriate.
- Processor 203 runs various programs stored in memory 207.
- processor 203 may be able to access a conventional computer network (e.g., a local area network, a wide area network, the Internet, etc.) via wireless communication with access points mounted within or proximate conference room 1 1.
- a conventional computer network e.g., a local area network, a wide area network, the Internet, etc.
- access points mounted within or proximate conference room 1 1.
- Communication between wireless devices like unit 200 and a network server via access points is well known in the wireless communication arts and therefore, in the interest of simplifying this explanation, will not be described here in detail.
- Keyboard 209 includes hardware keys that are akin to the keyboard keys described above with respect to Fig. 2.
- mechanical keys 208, 210, 216 and 220 are akin to keys 56, 60, 62 and 58 described above and can be used to resume a presentation, store images associated with a presentation, retrieve images presented by slave units so they can be re-presented by the master unit 28 and to send images from the master unit 28 to any one of the slave units, respectively.
- Number pad 214 is used in a manner similar to the number pad 67 described above with respect to Fig. 2. For instance, to indicate a slave unit associated with identifier number "2" to which an image should be flipped, an operator selects the "2" key from keyboard 209 followed by the send key 220.
- Left arrow key 222 is a send left key indicating, as its label implies, that an image currently presented via master unit 28 should be sent to a slave unit to the left of master unit 28.
- right arrow key 228 is a send right key indicating that an image currently displayed by the master unit 28 should be sent to the slave unit to the right of the master unit 28.
- Right directed arrow key 223 is a left retrieve key indicating that the image currently presented on a slave unit to the left of master unit 28 should be retrieved to the master unit and displayed thereby.
- left directed arrow key 226 is a right retrieve key indicating that an image currently presented by a slave unit to the right of master unit 28 should be retrieved and displayed via master unit 28.
- an enter key 212 is provided via unit 200 which can be used to indicate that information entered via other keyboard keys should be acted upon. For example, in cases where a presentation is to be resumed and a specific seven digit number code must be entered to access a specific previously stored image-unit set, after resume button 208 is selected, processor 203 may present a session identification number field via display 204 in which a specific sequence of seven numbers has to be entered in order to access the images corresponding to an image-unit set and present the images via the presentation units.
- unit 200 may include a full keyboard compliment including letters, numbers and function keys that are typically found on a computer keyboard so that unit 200 can, in effect, be used as a complete laptop computer to interact with various software applications (e.g., Power Point, spreadsheet applications, word processor applications, etc.).
- software applications e.g., Power Point, spreadsheet applications, word processor applications, etc.
- screen 204 is a fully functional touch sensitive flat panel display screen which can be used to display virtually any type of visual image including images corresponding to software applications, images corresponding to information applied to screen 204 via a stylus 202 or other similar types of interface tools and, in at least some cases, images that combine software generated images and applied information.
- a system operator may use stylus 202 to make a mark (e.g., 229 in Fig. 10a) on display 204 which is tracked by processor 203 and in response to which processor 203 changes the image on display 204 so that the mark is represented.
- the mark is referred to as a virtual ink mark because the mark appears on display 204 despite the fact that no real ink is applied to the surface of screen 204.
- the information presented via display 204 of control interface 200 is immediately updated on the master display 48 of unit 28.
- the operator can use HHD 200 to modify the image displayed on display 48 in a real time and collaborative flip chart like manner. After an image on display 48 is completed and when the operator wishes to flip the image from unit 28 to one of the slave units 22a or 22b in Fig. 1 , the operator uses HHD 200 to flip the image to the appropriate slave unit.
- processor 203 forms a flip command data packet commanding an image flip to the selected slave unit and including the master unit network address and transmits the flip command data packet to processor 80 (see again Fig. 3) via transceivers 21 1 and 20.
- processor 80 forms an image data packet including the currently displayed image and transmits the image data packet to the slave unit selected via HHD 200.
- unit 200 may be a stand alone laptop computer and may provide the complete data processing platform where master unit 28 is simply an output and input device.
- programs to track interactivity with display 20 may be run by unit 200 and unit 200 may simply provide display driving data to the master unit processor 80.
- the unit 200 may completely organize the image presentation and master unit 28 may not perform the flipping and retrieving processes.
- unit 200 may store all of the images including the images displayed by the master and slave units.
- the command may be received by unit 200 which in turn causes the flip to occur via transmission of the master image to the designated slave unit.
- unit 200 may also automatically transmit a command to the master unit to erase the flipped image. Retrieval commands would also be performed via unit 200 as opposed to via the master processor 80.
- a second exemplary system 230 according to at least some aspects of the present invention is illustrated.
- System 230 is shown in the context of a conference room like conference room 1 1 described above with respect to Fig. 1 where presentation units 48 and 232 are mounted on a rail 40 within the room for easy viewing of associated presentation surfaces by an audience.
- master unit 28 is similar to the master unit 28 described above with respect to Fig. 1 with few differences.
- master unit processor 80 in the Fig. 1 1 embodiment is programmed slightly differently than the processor described above with respect to Fig. 1. More specifically, because there is only one slave unit 232 in system 230, processor 80 is programmed to flip all images to single slave unit 232 when send commands are received.
- processor 80 is programmed to add an image identifier number to the flipped image which, in the example here, is added to the flipped image in the upper left hand corner.
- image identifier numbers "6" and “7” are associated with images presented on surfaces 250 and 248, respectively, and therefore, identifier numbers 6 and 7 have been added to each of the images so that each image can be subsequently uniquely identified.
- slave presentation unit 232 is a large format printer or plotter that includes a subset of the components or a set of components akin to the components illustrated in Fig. 5.
- unit 232 includes a processor 336, a motor 338, a printer 340 and a large roll of paper 342 as well as a transceiver 240.
- processor 336 is linked to motor 338, transceiver 240 and printer 340 and, when an image is flipped to unit 232, processor 336 controls motor 338 and printer 340 simultaneously to unroll a portion of the paper roll while applying ink to a front surface 250 thereof as the unrolled portion of the roll drops downward.
- printer 340 applies the image identifier number (e.g., "6" in Fig. 1 1 ) in the upper left hand corner of the image.
- rail 40 may include a corkboard front surface so that tacks can be used to post torn sheets there along.
- a corkboard front surface so that tacks can be used to post torn sheets there along.
- an exemplary torn sheet 234 having the number "7" as an identifier number is illustrated as being posted to rail 40 adjacent unit 232. It is contemplated that perforated lines may be provided at spaced locations along the length of the paper roll so that sheets can be torn off in a clean fashion.
- a system operator uses number pad 67 to select the number associated with the image to re-present and then selects retrieve key 62. For instance, to re-present the image on sheet 234 in Fig. 1 1 , the operator selects number "7" and retrieve key 62. After key 62 is selected, referring once again to Fig. 3, master unit processor 80 accesses the image stored in memory 88 corresponding to image identifier number "7" and re-presents that image via display 48.
- the system 251 includes a master presentation unit 48 and first and second slave units 252a and 252b, respectively.
- master unit 48 is mounted to a rail 40 between slave units 252a and 252b so that, when viewed from an audience's perspective, unit 252a is to the left of master unit 48 and unit 252b is to the right of master unit 48.
- Master unit 48 is similar to the master units described above and therefore will not be described here in detail.
- Unit 252a includes a hardened, generally rectilinear, plastic or metallic housing 258a, a transceiver 254a and a large format thin profile plasma, LCD or other thin profile display screen 256a.

- the slave processor is linked to display 256a and to slave transceiver 254a as well as to the slave memory.
- the keyboard on unit 28 may be used to identify the slave unit from which the image is to be retrieved and then to perform the retrieval process.
- the retrieval process may be completely internal to unit 28 where the image presented by the slave unit is stored in master unit memory 88.
- the retrieval process may require a retrieval request packet from master unit 28 to the slave unit (e.g., 252a in Fig. 12) to retrieve the image and then a second packet transmission from the slave unit back to master unit 28.
- System 470 includes a single presentation unit (also referred to by numeral 470) that includes a display 474 mounted within a rigid housing assembly 472 so that a display surface 475 is observable to the audience.

- unit 808 is simply an interface and the flipping/retrieving processes are performed by processor 810. For instance, when an image is flipped from unit 808 to space 822, unit 808 transmits a "flip" command to processor 810 which in turn causes projector 804 to display the image from screen 838 in space 822. When the image from space 822 is retrieved, a retrieve command is transmitted to processor 810 which in turn transmits the image being retrieved back to unit 808 to be displayed.

- DVD's and VCR's played via unit 818 may be presented on screen 838 or one of the projected spaces.
- a print icon 870 provided just above the space control icons on screen 838 may be selected thereby causing processor 810 to print the image currently via screen 838 via scanner/printer 816.
- Figs. 13 through 16 various methods and sub-methods consist of with certain aspects of the present invention are described. Each of the methods described herein may be used with at least one and in some cases more than one or even all of the systems described above or variations thereof.
- Fig. 13 a method 270 for flipping images from a master unit 28 to a slave unit is illustrated. Referring also to Figs 1-5, method 270 will be described in the context of system 10.
- a system operator arranges the master unit and the slave presentation units or devices for viewing by an audience within room 1 1.
- information is presented via master display 48.
- processor 80 monitors input devices such as keyboard 30, wireless control signals generated via HHD 200, etc., for a command to flip an image currently presented via unit 28 to one of the slave presentation units 22a and 22b.
- control loops back up the block 274 where the method described above is repeated.
- control passes to block 280 where master unit 48 transmits the master image as part of an image data packet to the selected slave unit.
- the selected slave unit presents the received image in any of the manners described above.
- sub-method 284 which may be used to replace blocks 280 and 282 in Fig. 13 is illustrated which correlates flipped images with image identifiers so that images can be subsequently re-accessed, re-presented and edited via master unit 28.
- sub-process 284 is to be used with systems that assign unique image identifiers to images generated by the slave units where the slave units then include (e.g., print) the image identifiers with the images when images are generated.
- sub-method 284 will described in the context of system 230 of Fig. 1 1.
- the master image is correlated with a unique image identifier number (e.g., "6" or "7" as illustrated in Fig. 1 1 ).
- master processor 80 stores the correlated image and image identifier number in master memory 88.
- master unit 28 transmits the master image to the selected slave unit.
- the selected slave unit presents the transmitted image along with the image identifier number.
- slave unit 232 generates the image on surface 250 and adds the image identifier number "6" in the upper left hand corner. At this point the image flip has been completed.
- master processor 80 monitors for a retrieval request for an image associated with a specific identifier number. For example, where identifier number "7" has been appended to an image on sheet 234 as indicated in Fig. 1 1 , the system operator may request retrieval of the image on sheet 234 via entry of number "7" and selection of the retrieve key 62 (see again Fig. 2).
- control loops back up through blocks 292 and 294.
- master unit 28 re-presents the correlated image via master display 48.
- a method 330 for managing flipchart images where each of the slave units is identifiable by a unique slave unit identifier as is the case in the embodiment of Fig. 1 is illustrated.
- slave unit 22a can be uniquely identified by number "1 " while unit 22b can be identified by number "2".
- a slave identifier e.g., 24a, 24b, etc.
- the slave identifier is associated in some fashion with the wireless network address corresponding to the identifier on the slave device.
- the associated slave identifiers and network addresses are stored in master unit memory 88.
- the master unit 28 and the slave presentation units 22a and 22b are arranged within room 1 1 for viewing by an audience.
- an image is presented and/or manipulated via master display 48.
- master unit processor 80 monitors for a flip command indicating that the currently displayed image should be flipped to one of the slave presentation units.
- control passes back up and through blocks 336 and 338.
- the master image is correlated with the slave identifier specified by the operator (i.e., the identity of the slave unit to which the image is to be flipped).
- master processor 80 stores the correlated image and slave identifier number in memory 88 and at block 346 master processor 80 transmits the master image to the slave unit.
- the slave unit presents the received image.
- master processor 80 monitors for a retrieve request indicating a specific slave identifier associated with a slave unit from which an image should be retrieved. At block 352, if a retrieval command is not received, control passes back up to block 348 and the loop described above is repeated. At block 352, after a retrieval command is received, control passes to block 354 where processor 80 accesses the image correlated with the slave identifier in master memory 88. At block 356, processor 80 re-presents the correlated image via master display 48.
- Method 360 is a method for correlating currently presented images with specific presentation units when a session store command is received, storing the correlated images and unit identifiers for subsequent access and then, when a resume command is received, for re-presenting the images via the presentation units associated therewith when the session store command was received.
- a session store command is received
- a resume command is received
- second and third images are presented via units 22a, 22b and master unit 28 when the store key 60 is selected, respectively.
- the first, second and third images are correlated with unit identifiers associated with units 22a, 22b and 28, respectively, the correlated data is stored in master memory 88 as an image set and then the presentation surfaces of units 22a, 22b and 28 are cleared. Subsequently, when an operator resumes the session corresponding to the stored image set, processor 28 flips the first and second images to slave units 22a and 22b, respectively, for presentation and presents the third image via display 48 so that the session can continue where the session left off. [0199] Referring to Figs. 1 , 2, 3 and 16, at block 362, images are presented via master display 48 and each of slave units 22a and 22b. At block 364, processor 80 monitors for selection of store key 60.
- processor 28 blanks master display 48 and transmits signals to each slave unit (e.g., 22a, 22b, etc.) causing each of the slave units to blank their respective presentation surfaces.
- data corresponding to the images from the presentation surfaces is maintained in master memory 88 or a combination of master memory 88 and the slave memories (e.g., 1 19 in Fig 5).
- processor 80 requests a session identifier from the operator that can be subsequently used to access the session images. For instance, processor 80 may provide a session identifier field and a query prompting the operator to name the session image set via master display 48. Where a text session identifier is preferred, processor 80 may also provide touch selectable icons comprising a full alphabetical keyboard via display 48 or, in the alternative, may be capable of recognizing hand writing within the session identifier field. Instead of requesting a session identifier at block 171 , processor 80 may simply assign a random access code to the session image set and temporarily provide the code to the operator via display 48.
- processor 80 correlates each image in the image set with a unique presentation unit identifier (i.e., an identifier that is unique to one of master unit 28 or one of the slave units (e.g., 22a, 22b, etc.).
- master processor 80 stores the session image set with the session identifier where each of the images is associated with a specific one of the master unit and the slave unit identifiers in master memory 88. After block 370 all of the session images have been stored in an accessible format for future reference.
- master processor 80 monitors for selection of resume icon 56 indicating that a previous collaborative session is to be resumed and therefore that a stored image set should be reaccessed and presented.
- resume icon 56 indicating that a previous collaborative session is to be resumed and therefore that a stored image set should be reaccessed and presented.
- control passes back up to block 374.
- resume command is received at block 376.
- master processor 80 provides a request prompting a system operator to provide a session identifier corresponding to a previously stored image set.
- the prompt may include a text query and a session identifier field along with a suitable set of touch sensitive icons (e.g., numbers, alphanumeric, etc.) for specifying an identifier.
- the image set associated with an entered session identifier is retrieved from memory 88 and at block 380 the images in the set are displayed via the master display and the slave units so that the previous session can continue where it left off.
- control passes back up to block 362 where the process described above continues.
- master processor 80 may be programmed such that, when store key 60 is selected once, the image currently presented via display 48 is stored and, when key 60 is selected twice in rapid succession (e.g., an action akin to a double-click of a mouse), processor 80 is programmed to store an entire compliment of session images as an image set.
- processor 80 may perform a process similar to the one described above with respect to storage of session image sets, requiring a specific text or numeric image identifier from the system operator that can be used to subsequently reaccess the image.
- processor 80 may provide a menu of options indicating the possible sources from which an image can be retrieved and suitable tools for accessing those images.
- a master presentation unit 528 similar to the master unit 28 of Fig. 2 is illustrated where the master unit 528 provides a set of touch sensitive icons in a lower margin area 530.
- the resume icon 56, send icon 58, store icon 60 and retrieve icon 62 as well as the left and right flip icons 68 and 70, respectively have functions that mirror the functions described above with respect to the similarly numbered keys in Fig. 2 and therefore, in the interest of simplifying this explanation, will not be described again here in detail.
- the main difference between the icon set provided via unit 528 and the key set provided via unit 28 is that the number pad 67 in Fig. 2 has been replaced by a thumb nail sketch bar 450 in Fig. 17.
- thumb nail of the flipped image will be presented via bar 450.
- two exemplary thumb nail sketches are identified by numerals 452 and 454.
- the system operator can simply select one of the thumb nail sketches (e.g., 452, 454, etc.) and retrieve icons 62 to re-present the image via display 48.
- all images flipped from master unit 528 to any of the slave units are stored and maintained within the master memory 88 until a system operator terminates a collaborative session and corresponding thumb nail sketches (e.g., 452, 454, etc.) are added to bar 450.
- thumb nail sketches e.g., 452, 454, etc.
- the system operator will still be able to quickly and easily access all flipped images independent of whether or not the images are currently presented via slave units or are simply stored in the master memory.
- Icons 64 and 66 are left and right scrolling icons that enable the operator to graphically search a large number of thumbnail sketches for specific images to re-present.
- a method may be implemented in software to quickly help a system user identify one of the units as a master unit, select a sub-set of units to operate as slave units from a larger set of units, to associate the master and selected slave units and provide tools for flipping images among the master and slave units.
- a method may be implemented in software to quickly help a system user identify one of the units as a master unit, select a sub-set of units to operate as slave units from a larger set of units, to associate the master and selected slave units and provide tools for flipping images among the master and slave units.
- presentation units 702, 704, 706, 708, 710 and 712 can be used for various purposes such as, for example, in private offices, in conference rooms, in public spaces such as a hallway or the entry to a cafeteria, etc.
- each of the units includes a flat panel display 714 mounted on top of a castered stand 716 so that the units can easily be transported from one location to another.
- two or more of the units are to be used together to facilitate a conferencing process where one of the units will be used as a master unit and the other unit or units will be used as slave units, it is contemplated that several units are brought to a conference space, associated with each other and can then run applications to facilitate the conferencing process.

- unit 702 wirelessly polls the conference space to identify other presentation units 704, 706, 708, 710 and 712 within the space.
- each unit 704, 706, 708, 710 and 712 When each of units 704, 706, 708, 710 and 712 receives the polling signals requesting that the units identify themselves as possible slave units, each unit 704, 706, 708, 710 and 712 transmits an information packet back to master unit 702 identifying the slave unit by its unique wireless network address. For example, consistent with the exemplary addresses above, unit 704 transmits an information packet including unique address 54478B1 , unit 706 transmits an information packet including unique address 89908B1 , etc. When unit 702 receives the return information packets from the possible slave units, unit 702 identifies each of the possible slave units, associates a unique simple identifier with each of the slave units and then further facilitates the configuration process. To this end, in the present example, master unit 702 identifies five separate slave units 704, 706, 708, 710 and 712 and associates simple identifiers 1 , 2, 3, 4 and 5 therewith, respectively.
- master unit 702 transmits information packets back to each of the five slave units 704, 706, 708, 710 and 712 assigning the simple identifier labels to each.
- the identifier labels include numbers 1 , 2, 3, 4 and 5 which are transmitted to units 704, 706, 708, 710 and 712, respectively.

- icons corresponding to the simple labels e.g., 752, 754, etc.
- icon 762 is associated with label 752 and hence with slave unit 704.
- icons 766, 768, 770 and 772 are associated with labels 754, 756, 758 and 760 and hence with slave units 706, 708, 710 and 712, respectively.
- An enter icon 774 is also provided near the bottom of the master unit display.
- a sub-set of the slave units 704-712 can be selected by selecting a sub-set of the icons 762, 766, 768, 770 and 772 and then selecting ENTER icon 774.
- an operator select icons 766, 768 and 770 and then selects ENTER icon 774. This process of monitoring for slave unit sub-set specifying activity is represented by blocks 740 and 742 in Fig. 25.
- master unit 702 provides a control interface including the master label 750 designation and provides icons suitable for flipping master images to the sub-set of selected slave units and for retrieving images from the selected sub-set of slave units.
- master unit 702 provides a separate flipping/retrieving icon 782, 784 and 786 for each of the selected sub-set of slave units 706, 708 and 710, respectively.
- the flipping/retrieving icons 782, 784 and 786 are similar and operate in a similar fashion and therefore, of interest of simplifying this explanation, only icon 784 will be described here in any detail.
- Icon 784 includes a flip arrow icon 769 and a retrieve arrow icon 771 .
- flip icon 769 an image currently displayed via the master display is flipped or transmitted to the slave unit 708 associated with icon 784 (i.e., unit 708 that is associated with simple label 754).
- retrieve arrow icon 771 the image currently displayed via slave unit 708 is retrieved and displayed via the master display unit 702.

It is also contemplated that, in at least some applications, when a system user uses one of the master presentation units to perform a presentation, all activity that occurs in the corresponding subsystem would be replicated in the other subsystem. For example, when a system user makes changes to information on master display screen 902, those changes would be, essentially in real time, replicated on remote master presentation screen 907.
- activity that alters an image in master presentation space 907 would also automatically and essentially in real time alter a similar image in master presentation space 902.

- the master and slave units may have identical constructions and functionality so that images can be edited via any of the units and can be flipped from or retrieved to any of the units.
- an operator may move among the units editing and flipping and retrieving in an enhanced collaborative fashion.
- the invention contemplates many different types of rail configurations including other hook to hook type rails, rails that may receive wheels mounted on the master and slave units, rails that are only mountable via the ends thereof (e.g., the rail may restrict removal of mounted units via upward or forward motion - this is particularly important in cases where the units are relatively expensive) and other system where the units include securing structure to more effectively secure the units to the rail members 40.
- any of the inventive systems may also include a standard sized printer/scanner (e.g., 8 /4" x 1 1 ", legal size, etc.) for printing copies of displayed images for meeting attendants to use during a meeting or to take from the meeting or so that documents can be quickly scanned in for viewing and editing via the system.

At least some of the conference attendees may have and may be using personal interface devices including, for instance, laptop computers 91 1 , 913, 915, etc., to participate in the conference. In Fig. 29, laptops 91 1 and 913 are linked via a LAN to subsystem 900 while laptop 915 is linked to subsystem 900 via WAN 920.
- laptops 91 1 and 913 are used within the conferencing space that includes subsystem 900 such that the laptop users can view their laptop displays, the image presented via master unit 902 or the slave images (e.g., 904, 906, etc.) presented via a slave presentation space 969.

- conference attendees within the conference room that includes subsystem 900 can observe an image presented via master unit 902 as well as each of the four images illustrated in Fig. 33.
- any activity that is performed by the components of sub-system 900 may be repeated via the components of sub-system 901 essentially in real time so that attendees in the separate conference spaces associated with subsystems 900 and 901 can simultaneously view image activities.
- the image displayed via the sub-space of space 969 that is labeled "2" is altered, the image displayed via the sub-space of space 971 that is labeled "2" would likewise be altered so that whatever images are presented via sub-system 900 would likewise be presented via sub-system 901.

- the remaining space is used to accommodate tool area 1202.
- a maximum size 2:3 aspect ratio i.e., 2 wide by 3 high
- an 18:5 format tool area 1002 can be configured.
- the 18:5 tool area format was selected primarily because that ratio is generally consistent with the largest 2:3 workspace area 1004 that can be obtained with a 16:9 display screen.
- the workspace area 1004 should be dimensioned within the 2:3 to 3:4 range.
- tool area 1002 instead of locating tool area 1002 along the top edge of the screen, tool area 1002 could be located along the bottom edge.
- tool area 1002 could be divided into first and second separate tool areas located along the top and bottom edges of the screen where each of the tool areas has a 36:5 aspect ratio or some other ratios that, when combined, result in an 18:5 ratio.
- the workspace area 1004 may be made smaller than the maximum size possible for a 16:9 screen but still having the desired 2:3 to 3:4 aspect ratio.
- Other exemplary screen shots corresponding to 4:3 aspect ratio display screens in portrait and landscape orientation and to a 16:9 aspect ratio display screen in landscape orientation are described hereafter with reference to Figs. 40, 42 and 43.
- tool area 1002 includes a plurality of on-screen icons that are selectable by the presenter for changing the information displayed via unit 902 and on slave presentation space 969.
- the onscreen icons may be selectable in any of several different ways such as, for example, via touch, stylus, movement and activation of a mouse controlled pointing icon, a track ball, etc.
- unit 902 includes sensors for identifying when a location on the display screen is touched and the position of the touching activity, unless indicated otherwise.
- exemplary screen shot 1030 that may be presented to a user of one of the personal interface devices 91 1 , 913, 915, etc., according to at least some inventive embodiments.
- the information presented to the remote user includes all of the information that is presented to conference attendees within the conference space that includes subsystem 900.
- exemplary screen shot 1030 includes five windows, a separate window corresponding to each of the images currently displayed via master unit 902 and the slave images 1022, 1024, 1026 and 1028 presented in space 969.
- window 1032 corresponds to the image displayed via master unit 902 while windows 1034, 1036, 1038 and 1040 correspond to slave images 1022, 1024, 1026 and 1028, respectively, as illustrated in Fig. 33.

Once pen icon 1070 has been selected, the mechanical or electronic stylus is useable to apply markings to the image in workspace area 1004.
- Eraser icon 1062 is selectable to indicate to master unit 902 that the mechanical stylus is to be treated as an eraser for removing or erasing information from the master unit display screen. Once icon 1062 is selected, the mechanical stylus tip can be moved about the screen surface within area 1004 to remove information previously applied via the pen tool.
- a button (not illustrated) on the stylus may be selected to indicate a desire to use the stylus as an eraser. When the stylus eraser button is selected and the master unit sensors sense stylus activity, the activity is assumed to be erasing activity.
- Pointer icon 1064 is selectable to indicate to master unit 902 that the stylus should be used as a pointing device instead of as an eraser or as a pen for, for example, selecting information within workspace area 1004, selecting on screen icons within workspace area 1004 when software applications that use on screen icons as input are running, moving selected and/or non-selected information on the display screen, rotating screen information, re-sizing screen information, etc.
- the selected icon is, in at least some embodiments, highlighted in some fashion to indicate selection. For instance, when pen icon 1070 is not selected, a pen cap is presented as covering the pen tip as illustrated in Fig. 32. When pen icon 1070 is selected, the cap is eliminated to expose the tip as illustrated in Fig. 35.
- eraser icon 1062 and pointer icon 1064 will be visually distinguished in some fashion when selected.
- Icon 1068 is selectable to open one or more drop down menus associated with a currently selected one of icons 1062, 1064 or 1070.

- icon 1010 may be used to move the information within space 1008 from the upper left-hand corner of area 1004 down to the lower right-hand corner where the information may be dropped.
- pointer 1010 may be used to move information from an image displayed via workspace area 1004 to one of the panel icons in tool area 1002 and hence to an image associated with the panel icon.
- pointer icon 1010 can be used to move the information in space 1008 up and into an associating position relative to one of the panel icons in area 1002.
- area 1008 is shown as attached to icon 1010 which is moved up to panel icon 6 to move the information in space 1008 to the image associated with panel icon 6.
- Fig. 39 after information has been moved to the image associated with panel icon 6, the next time the image associated with panel icon 6 is displayed via either the master unit 902 or as one of the slave images, the information moved thereto is presented as a visually distinguished part of the image.
- space 1008 is illustrated in the upper left- hand corner with a rectilinear dotted line box therearound to visually distinguish the information from the remainder of the image.
- the pointer icon can be used at this time to move space 1008 to any location within area 1004.
- the pointer icon can also be used to click, double click, drag, etc., on a personal computing device "remote view" as they are locally connected.
- a separate keyboard can be used to type information into the personal computing device.
- the display screen 955 of a master unit 951 may be rotated between portrait and landscape orientations and that, when the display is rotated, several things occur.
- the on-screen icons or tools may be rearranged to best accommodate presentation of information.
- workspace area 1004 should have dimensions that are similar to the dimensions of a typical flip-chart page irrespective of the master unit display format (i.e., aspect ratio) and orientation.
- a typical flip-chart page will usually have between a 3:2 and a 4:3 format while master unit display screens will typically come in two different formats including either a 4:3 or a 16:9 format.
- the tool area may be differently oriented when a master display screen is in the portrait and landscape orientations.
- the tool area 1002 is presented along the upper edge of screenshots 1000.
- the tool area 1002 will have an 18:5 format (i.e., 18 wide by 5 high) which leaves a 2:3 format workspace 1004.
- each of the displayed slave images may also have a 2:3 format (see generally Fig. 30).
- Fig. 40 when a 16:9 format master unit screen is rotated into the landscape orientation, in at least some embodiments, the tool area 1202 is provided along a left-hand edge of a resulting screen shot 1200 with a workspace area 1216 to the right thereof.
- area 1216 is presented in a 4:3 format with the tool area 1202 presented in a 4:9 format.
- the tool icons are rearranged. Nevertheless, the tools have a similar look and feel to the tools that were provided when the screen was in the portrait orientation and therefore operation thereof should be intuitive.
- the slave images are also rotated from portrait into landscape orientation and the sizes of the slave images are increased such that a reduced set of slave images are presented (see and compare Figs. 33 and 41 ).
- Figs. 33 and 41 instead of presenting four portrait slave images as in Fig. 33 after rotation into the landscape orientation, only two slave images are presented on space 969 and each of those images is in the landscape orientation.
- area 1216 in Fig. 40 has a 4:3 format
- slave images in Fig. 41 would also have a 4:3 format in this example.
- an orientation change button icon 1 1 12 is provided in tool section 1060 for switching between portrait and landscape orientations.
- button 1 1 12 is selected and the information is currently displayed via the master unit screen such that the workspace area is in a portrait orientation, the displayed information is rearranged so that the workspace area is in a landscape orientation and the tool area is repositioned accordingly.
- exemplary screenshots 1221 and 1240 are illustrated that correspond to portrait and landscape orientations of a 4:3 format screen.
- portrait oriented screenshot 1221 includes a relatively thin tool area 1225 that extends along a left edge thereof and a workspace area 1223 to the right of tool area 1225.
- the tool area has a 1 :12 format while the workspace area 1223 has a 2:3 format.
- the on-screen tool icons are divided into two separate sub-groups and are arranged in two separate tool areas, a first area 1242 along the left edge of the screenshot 1240 and a second area 1246 along the lower edge of screenshot 1240.
- the source icons are provided within second area 1246 and all other tool icons are provided in first area 1242.
- the remaining area 1244 forms a workspace area which, in this embodiment, has a 4:3 format.
- first tool area 1242 will have a 1 :9 format and second area 1246 will have a 16:1 format.
- Other screenshot formats are contemplated.
- a second exemplary tool area 1300 that is similar to area 1002 shown in Fig. 35 is illustrated.
- Many of the tool icons shown in tool area 1300 are identical or substantially identical to the tool icons shown in Fig. 35 and operate in a similar fashion and therefore, in the interest of simplifying this explanation, many of the tool icons shown in Fig. 44 will not again be described here in detail.
- the primary distinction between tool area 1300 and tool area 1002 is the way in which panel icons or session image representations within area 1300 that correspond to images presented via slave presentation spaces or units are visually distinguished from other panel icons or session image representations (i.e., session image representations that are not associated with currently presented slave images).
- Figs. 35 and 44 currently presented slave images are identified as 1 ; 2; 3; 4; 5; and 6; that are presented in slave presentation spaces 1310, 1312, 1314, 1316, 1318 and 1320, respectively.
- panel icons that are associated with currently displayed slave images in Fig. 35 are marked via token icons (e.g., 1083, 1084, etc.)
- token icons e.g., 1083, 1084, etc.
- panel icons associated with currently presented slave images are provided within a slave representation area 1302 that is circumscribed by a field boundary (also labeled 1302) that forms a box.
- the slave representation area 1302 is provided in the upper left hand corner of the space within tool area 1300 reserved for panel icons.
- slave representation area 1302 is further divided into a plurality of slave representation fields, a separate field for each of the slave image presentation spaces in which slave images can be displayed. For example, where a presentation system includes three projectors and each projector can project two separate images so that the system can project a total of six slave images, the slave representation area 1302 includes six separate slave representation fields. Consistent with this example, in Fig. 44, six separate slave presentation spaces 1310, 1312, 1314, 1316, 1318 and 1320 for presenting six slave images 1 i, 2i, 3i, 4i, 5i, and 6i for conference attendees to view are illustrated.
- slave representation area 1302 is divided into first through sixth separate slave representation fields that are aligned in a single row within area 1302 and that are identified by numerals 1301 , 1303, 1305, 1307, 1309 and 131 1 , respectively.
- Additional session image representation fields 1313, 1315, 1317, 1319, 1321 and 1323 are provide outside slave representation area 1302 for panel icons that are not associated with currently presented slave images.
- panel icons within slave representation area 1302 are identified by numeral 1 , 2, 3, 4, 5, and 6 and correspond to currently presented slave images identified by labels 1 i, 2i, 3i, 4i, 5i and 6i that are presented within slave presentation spaces 1310, 1312, 1314, 1316, 1318 and 1320, respectively.
- Fig. 45 Several ways to modify which slave images are presented via a conferencing system by manipulating icons within tool area 1300 are contemplated.
- one way to modify presented slave images is to select one of the panel icons within slave representation area 1302 via a mouse controlled cursor or the like and drag the selected icon or representation to another location outside area 1302.
- a dragging action is shown wherein panel icon 4 is dragged from slave representation field 1307 down to a field 1325 located outside area 1302 as indicated by arrow 1340.
- icon 4 is released, the panel icon 4 is positioned within field 1325 adjacent panel icon 12.
- FIG. 45 when panel icon 4 is removed from slave representation area 1302, field 1307 is empty and, as illustrated, the image 4i previously presented within slave presentation space 1316 (compare Figs. 44 and 45) is removed leaving space 1316 blank.
- FIG. 44 another way to modify the images currently presented via the slave presentation spaces is to select one of the panel icons within slave representation area 1302 via a mouse controlled pointing icon or the like and drag the selected panel icon to another location within area 1302.
- a pointing icon may be used to select panel icon 4 and drag the selected representation to a location between fields 1301 and 1303.
- the panel icon 4 is placed within field 1303 and panel icons 2 and 3 are moved one field to the right into fields 1305 and 1307, respectively.
- the panels icons within area 1302 are repositioned in this manner, the images presented with presentation spaces 1312, 1314 and 1316 are similarly modified such that images 4i, 2i and 3i are presented within presentation spaces 1312, 1314, and 1316.
- a pointer icon may be used to select panel icon 1 1 and to drag the selected panel icon to a location within area 1302 between fields 1303 and 1305 as indicated by arrow 1342.
- panel icon 1 1 is released between fields 1303 and 1305, panel icon 3 is moved from its location in field 1305 to field 1307 and panel icon 1 1 is positioned with field 1305. Reflecting the change, within area 1302, the presented slave images in slave presentation spaces 13 14 and 1316 are updated to include images 1 1 i and 3i (see Fig. 47).
- panel icons to the right of field 1321 are moved one field to the left as indicated by arrows 1350 and 1352 that show panel icons 12 and 4 moving leftward, respectively.
- panel icons within area 1302 to the right of the location to which the panel icon is dragged move one field to the right and the next empty field to the right receives a panel icon.
- Fig. 48 with a separate panel icon in each of the slave representation fields in area 1302, when another panel icon is moved to a specific location within area 1302, panel icons within fields to the right of the specific location within area 1302 move one field to the right and the right most panel icon within area
- 1302 is moved out of area 1302. For example, as shown in Fig. 48, when panel icon 12 is selected from field 1321 and dragged to a location between fields 1301 and
- panel icons 1 , 12, 2, 1 1 , 3 and 5 are shown in fields 1301 , 1303, 1305, 1307, 1309 and 131 1 , corresponding images 1 i, 12i, 2i, 1 1 i, 3i and 5i are presented within spaces 1310, 1312, 1314, 1316, 1318 and 1320, respectively.
- a first presentation system may include three projectors where each projector is capable of presenting two separate images for a total of six slave images while a second system may include four projectors, each projector capable of displaying two separate slave images for a total of eight slave images.
- a secondary slave representation area 1366 is shown adjacent a primary slave representation area 1302 and includes two additional slave representation fields 1368 and 1370 that correspond to seventh and eighth slave presentation spaces 1321 a 1323a of one of the presentation systems.
- slave presentation spaces 1310, 1312, 1314, 1316, 1318 and 1320 corresponding to a first presentation system present images 1 i, 12i, 2i, 1 1 i, 3i and 5i, respectively, which are associated with panel icons 1 , 12, 2, 1 1 , 3 and 5, respectively, in slave representation area 1302.
- images 1 i, 12i, 2k, 1 1 i, 3i, and 5i are presented via the second system in slave presentation spaces 1310a, 1312a, 1314a, 1316a, 1318a and 1320a, respectively, while images 6i and 7i are presented in presentation spaces 1321 a 1323a that correspond to fields 1368 and 1370 in secondary slave representation area 1366.
- each of the systems will retain copies of session images such that the session may be continued despite termination of the remote link.
- the remote link is terminated, where a first system supports fewer slave presentations spaces than a second system, upon delinking, the secondary slave representation area 1366 is removed so that panel icons therein are no longer visually distinguished in the first system.
- the primary slave representation area 1302 is expanded to include panel icons and associated fields corresponding to all of the supported slave presentation spaces.
- the first system upon delinking, the first system generates a tool area 1300 as illustrated in Fig. 49 wherein the representation area 1302 includes six panel icons while the second system generates a tool area 1300 as illustrated in Fig. 51 where the slave representation area 1302a includes eight panel icons and eight separate slave representation fields (not labeled).
- a server managing the conference will poll the remote device to identify printers associated therewith and will then store network addresses associated with the identified printers for subsequent use. Thereafter, referring to Fig. 52, any time during a conference or thereafter, a system user may select printer icon 1076 to open a print window 1380.
- Exemplary print window 1380 includes a list 1382 of printers associated with devices used to facilitate a conferencing session, a separate selection field 1384 for each one of the associated printers and a print button icon 1386.

- any type of pointing device may be used to directly interact with a master presentation unit via contact.
- a unit operator may be able to use the tip of her finger to select onscreen icons, to draw within a work space, to erase objects within a work space, to select and drag objects within a work space, etc. or, may be able to use a stylus or pen type device to perform the same functions.
- a finger or a stylus type device can each be employed, it has been recognized that, in at least some embodiments, operator interaction with a master unit can be enhanced by employing dual sensing technologies and different algorithms depending upon which of a finger and another pointing device are employed to perform interactive functions.
- the primary sensor for sensing interactivity with a display surface 1604 of a master presentation unit 1602 will include a laser 1606 or other system that generates a light plane 1610 parallel to and slightly separated from surface 1604 by a gap 1612 (e.g., 1/8 to 1/4 inch).
- a laser 1606 or other system that generates a light plane 1610 parallel to and slightly separated from surface 1604 by a gap 1612 (e.g., 1/8 to 1/4 inch).
- surface interaction and interaction location are generally determined by sensing light plane 1610 penetration and the location at which the penetration occurs.
- non-contact activity Usually non-contact activity only occurs over a short duration (e.g., 0.5 to 1.0 seconds).
- a secondary sensing system in addition to a light plane sensing system for sensing penetration location, is employed for sensing contact of a stylus/pen tip with a display surface.
- the secondary sensing system includes a stylus/pen device 1620 and a receiver 1608.
- Stylus device 1620 includes a tip contact sensor 1622 and an rf or other type transmitter 1624.
- Sensor 1622 senses when the tip of the device 1620 contacts a surface such as, for instance, display surface 1604.
- transmitter 1624 transmits an rf or other type signal to receiver indicating that a device other than a finger tip has contacted surface 1604.
- device 1620 may transmit additional information such as the nature of device 1620 (e.g., a pen, eraser, pointing device, etc.) color, swath thickness, etc.
- a processor 1630 linked to receiver 1608 and the penetration sensor (not separately labeled) that forms part of the light plane sensing system is programmed to identify both position using the light plane sensing system and contact using signals from receiver 1608.
- a processor 1630 linked to receiver 1608 and the penetration sensor (not separately labeled) that forms part of the light plane sensing system is programmed to identify both position using the light plane sensing system and contact using signals from receiver 1608.
- a transmitting stylus type device is employed, non-contact activity can be eliminated.
- at least some inventive embodiments include a system processor (see 1630 in Fig. 60) programmed to perform the distinguishing method illustrated in Fig. 61.
- the processor 1630 is programmed to operate in either one of two interactive modes including a finger mode and a stylus mode.
- a timer T is set equal to zero
- flag labeled flagi is set equal to zero
- a threshold duration T r is set. For example, to one second.
- processor at block 1568 where no light plane penetration has occurred, control passes up to block 1566. After light plane penetration does occur at block 1568, control passes to block 1570.
- processor 1630 determines whether or not the currently set mode is the finger mode or the stylus mode.
- processor 1630 stores penetration location information.
- processor 1630 starts timer T.
- processor 1630 determines whether or not a stylus signal has been received from a transmitting stylus like the stylus 1620 illustrated in Fig. 60. When a transmitted stylus signal is received, control passes to block 1569 where the stored penetration data is deleted.
- flagi is set equal to one to indicate that, for the current light plane penetration, a stylus signal has been received.
- processor 1630 commences drawing a line from the current location after which control passes back up to block 1578.
- block 1578 when a stylus user lifts the stylus 1620 so that the tip thereof no longer is in contact with display service 1604, control passes from decision block 1578 to decision block 1576.
- flagi is equal to 1 indicating that a stylus signal was previously received during display surface interaction
- processor 1630 determines whether or not penetration continues. Where penetration ceases, control passes from block 1565 to block 1578 where the stored penetration data is used to draw a line. After block 1578, control passes back up to block 1562 as illustrated where the finger mode is reset.
- Timer value T is compared to threshold duration T r .
- Threshold duration T r is set equal to a reasonable time period for passing from the light plane level to the surface contacting level. For example, in some cases, duration T r may be one second, two seconds, one-half second, etc.
- processor 1630 When the threshold duration is exceeded, processor 1630 is programmed to perform as if the tip or device that penetrated light plane 1610 is a tip or device other than a transmitting stylus type device and control passes to block 1561 .
- processor 1630 sets the mode to the finger mode.
- processor 1630 uses the stored data to draw a line penetration location. After block 1563, control passes to block 1631 in Fig. 61. [0317] Referring again to Fig. 61 , at block 1570, when the system is in the finger mode, control passes to block 1579 where commences line drawing at the current light plane penetration location. After block 1579, control passes to block 1631 where processor 1630 determines whether or not penetration continues. Where penetration ceases, control passes to block 1577 where processor 1630 ceases line drawing after which control passes to block 1564.
- processor 1630 determines whether or not a stylus signal has been received. If no stylus signal has been received, processor 1630 continues to operate in finger mode and control passes back up to block 1631 where the process described above is repeated.
- the stylus/finger mode setting algorithm has been described above in the context of a stylus that continually transmits a signal when the stylus tip contacts the surface of a display, in other embodiments the stylus may transmit pen down and pen up signals when the stylus makes initial contact and when contact ceases, respectively, and the processor may be programmed to recognize the period between down and up signals as a contact period.
- a system that includes a master unit and multiple slave presentation spaces can be used to facilitate unique help functions where help information can be provided simultaneously via a subset of presentation spaces and/or during normal operation of the system to perform interactive tasks.
- a master unit screen shot 1509 and related first through sixth slave presentation spaces 1522, 1524, 1526, 1528, 1530 and 1532, respectively, are illustrated where the master screen shot includes, among other things, a workspace area 1510, a tool area 1300, a slave representation area 1302 and a help button 1512.
- a help window 1516 is opened within workspace area 1510 that presents help topics in some fashion, a "close help" icon 1521 and a close help window icon 1518. After window 1516 is opened, to close the window, icon 1518 can be selected.
- icon 1516 is selected, while window 1516 closes, in at least some embodiments other help information that may have been accessed may remain in some presented format for viewing. In at least some cases, to close all help information and to present information that was presented prior to opening the help window, the close help icon 1521 can be selected.
- help topics are shown in a list format 1514 and topics are selectable via a mouse or other controlled pointing icon 1520.
- icon 1520 When icon 1520 is positioned over a topic, the topic is highlighted to indicate alignment with the topic. Once a topic is selected, the topic is highlighted in a different fashion to indicate that selection has occurred.
- a system processor accesses a help database, retrieves help information and presents the help information within workspace area 1510 or within a window that appears over the screen shot 1509.
- the presented help information may include simple text, hyperlink or other linking text that, when selected, leads to other related information, animation to show activities related to selected topics, etc.
- a system user may want to simultaneously use a system including a master unit and slave units while viewing or having access to help information. For instance, where a system user is not sure how to move panel icons into and out of the slave representation area 1302 and the resulting effect of movement on the images presented via the slave presentation spaces (e.g., 1522, 1524, etc.), it may be advantageous for the user to have access to help information (e.g., text, an animation, etc.) that explains how panel icons can be moved in and out of area 1302 and the resulting effect on slave images while simultaneously being able to perform the panel icon dragging and releasing activity.
- help information e.g., text, an animation, etc.
- a system user can flip the help information from the master area 1510 to one of the slave presentation spaces 1522, 1524, etc., and can then use the master unit to perform some activity while help information is presented in the slave space.
- the window may be flipped to a slave presentation space in at least some embodiments by selecting the window (i.e., selecting the top bar of the window), dragging the window to a location over one of the panel icons within the slave representation space 1302 and releasing the panel icon. Once the panel icon is released, the help window is moved to the slave presentation space associated with the panel icon and will appear as a window over the image that currently exists within the slave presentation space.
- a flipped help window may be associated with the slave presentation space or the image over which the help window was flipped.
- help window is associated with the slave presentation space to which the window was flipped, as other images are moved about the slave spaces, the help window would not simultaneously be moved.
- help window is associated with an image over which the window is initially flipped, as the image is moved, the help window would simultaneously move.
- help information in a window format is that, at least where the help window does not take up an entire slave presentation space, at least a portion of the any underlying image is still visible and hence, when an activity affects the underlying image, at least a portion of the affect can be observed to confirm the effect.
- help information when the help information is flipped to a slave presentation space, the help information may either be treated like any other slave image and supplant an existing image or may be treated in an overlaying fashion so that any initial image in the space to which the information is flipped remains associated with the space.
- any image presented within a slave presentation space prior to flipping is removed from the space and repositioned according to the image management rules described above. For instance, where an image is initially presented in slave presentation space 1522 when a help information image is dragged to and released to a location over the first panel icon in slave representation space 1302 that is associated with slave presentation space 1522 (see again Fig. 62), the initial image in space 1522 is moved to space 1524, any initial image is space 1524 is moved to space 1526 and so on.
- any image presented within a slave presentation space prior to flipping is removed from the space so that the help information can be presented within the space but the removed image is not repositioned in another of the slave presentation spaces and the flipping action does not cause other images presented in the slave presentation spaces to be moved within the spaces. For instance, where an image is initially presented in slave presentation space 1522 when a help information image is dragged to and released to a location over the first panel icon in slave representation space 1302 that is associated with slave presentation space 1522 (see again Fig. 62), the initial image in space 1522 is removed from space 1522 so that the help information can be presented.
- the topic information may initially be presented in a slave presentation space instead of being presented in the master unit workspace area 1510.
- the help information may be presented via multiple slave presentation spaces.
- help topic when a help topic is selected and help information is initially presented within the master unit workspace area 1510, as additional topics are selected, information related to previous help topics may be displayed via the slave presentation spaces. For instance, where a user initially selects a first help topic to obtain related information and a help window is opened over workspace area 1510 that includes additional selectable help sub-topics in addition to information related to the first topic, when a second help topic is selected from the additional sub-topics, information related to the first topic may automatically be flipped in a window or other format to the first slave presentation space 1522 and either another window may be opened within workspace area 1510 to present information related to the second topic or the second help topic information may be presented in the initial window.
- information related to the second topic may automatically be flipped in another window or other format to the second slave presentation space 1524 and either another window may be opened within workspace area 1510 to present information related to the third topic or the third help topic information may be presented in the initial window.
- help information can be removed from the presented images by simply turning off the help function.
- the help function can be turned off by simply selecting help icon 1512 in Fig. 62 and then selecting the close help icon 1521.
- the state of the system returns to the state that existed just prior to the help function being turned on.
- the help function is turned off, all of the seven originally presented images are again presented.
- any changes that occurred to the presented information while the help function was turned on remain. For instance, if three help images are presented during help activities via slave presentation spaces 1522, 1524 and 1526 where the help information images were treated like normal flipped images (i.e., caused movement of other images among presentation spaces), when the help function is turned off the three spaces 1522, 1524 and 1526 are left blank.
- a help function may be supported by a system wherein a related activity is simulated via the system for a user. For instance, again, where a user seeks help information related to movement of panel icons into and out of a slave representation area 1302 (see again Fig. 47), to show the activity and the result, a system processor may actually show a dragging and releasing activity via the master unit and the effect of the activity via the slave presentation spaces (i.e., the slave images may be moved or altered accordingly).
- the processor may cause the master unit to show a pointing icon move to a panel icon in the tool area 1300 to select one of the panel icons, dragging of the panel icon to another location, releasing of the icon and replacement of the icon while causing the slave presentation unit to alter the displayed slave images accordingly.
- help information is presented in windows
- the windows may be presented as small sticky notes where, as new help topics are opened, the new notes are presented via either the master unit or within the slave presentation spaces.
- the note appearance is an indication to a system user that the information on presented via the notes is not permanent and that the images under the presented information still exist and will be there after the help function is turned off.
- the sticky notes may only be used for help navigation. For instance, when a help function is initially commenced, general help topics may be presented via a first sticky note. When a sub-topic from the first note is selected, a second note may be presented either via the master or via the slave spaces that includes more specific topics and so on.
- a master unit or other interface device that is used with a master presentation unit may be useable to adjust viewing aspects such as, for instance, brightness, contrast, etc., of the slave presentation units so that each presentation unit projects images that have similar appearances.
- the projectors will project images that have different brightness levels, color contrasts, etc., because different types of projectors are employed or, where identical projectors are employed, because the usage time of the projectors is substantially different (i.e., as projectors are used, the quality of the projected images is denigrated, projector light brightness is reduced, etc.).
- first and second instances of a single image are presented via first and second separate projectors in first and second presentation spaces, often because of hardware differences, despite the fact that the images are identical, the images may have very different appearances. While different appearances are acceptable when the first and second presentation spaces are used in different locations (i.e., separate conference rooms), when the two spaces are adjacent, the differences in appearance are noticeable and, in many cases, can be distracting.

- a user ID e.g. a user name like "John Smith" as illustrated, a user's initials, etc.
- a similar user identifier box may follow a pen or cursor icon about on a display to indicate who is controlling the cursor at any time.
- a feature may be turned on whereby, when a stroke or other image object on an image is selected (e.g., via hovering an icon over the stroke/object or via clicking on the stroke/object), the identity of the person that added the stroke or object to the image may be indicated.
- the identity may be indicated in any of several ways including highlighting the remote icon (e.g., one of icons 1805 in Fig. 65) that is associated with the remote computer that was used to make the stroke or add the object, by providing a user identifier akin to field 1807 in Fig.
- a feature may be provided such that when the feature is turned on the authors of all of the information on an image may be provided.

- any device used to electronically link to a system conference may be used to load documents up to the conference through a print type process.
- a tool space 1850 akin to the space described with respect to Fig. 44 is shown which includes a slave representation area 1852 and a plurality of remote user icons including one remote user icon 1854. As shown in Fig. 67, initially no images are shown in slave representation area 1852.
- the attendee associated with remote icon 1854 wants to load an eight page document from some other application such as MS WordTM, the attendee can select a print command and can then select the conferencing system including the master unit or easel as the target to which the image should be printed. After the selections above, a version of the eight page document can be generated within the remote computer and presented on the remote computer via windows associated with the conferencing system. In addition, a version of the eight page document can be transmitted to the master unit or easel and used to populate the six slave representation fields 1860, 1862, 1864, 1866, 1868 and 1870 in space 1852 as well as two session image fields 1874 and 1876 as seen in Fig. 68.
- the images would also be presented via the master unit workspace 1004 as well as via the slave presentation spaces for viewing. Thereafter, any of the image changing and session image rearranging processes described above may be performed on the images displayed.
- any of the image changing and session image rearranging processes described above may be performed on the images displayed.
- FIG. 68 In the above example, if another attendee associated with icon 1908 subsequently wants to upload two additional images and the second image in field 1862 is currently displayed on the master unit as indicated by the highlighting in Fig. 68, when the two page document is printed to the conferencing system, versions of the two new images are generated that cause the previous images to ripple from space 1862 onward to make room for the two new images. The results of this rippling activity are shown in Fig.
- projector systems similar to the systems described above with respect to Figs. 58 and 59 may be designed into furniture that has a conventional appearance where the furniture does not include a slave display space (e.g., the furniture includes no screen) but rather uses a flat substantially vertical surface provided by some other structure as a projection surface.
- an exemplary system 1940 is shown in Figs.
- credenza 1940 includes a rectilinear wall structure 1942 that forms an internal cavity 50 for receiving at least a subset of system components, a plurality of doors, two collectively identified by numeral 1944, internal wall and shelf structure 1952 and a glass top member 1946.
- Projectors 1954 and 1956 are arranged on a top shelf just below the glass top.
- Each projector 1954 and 1956 has a similar design and operates in a similar fashion and therefore, in the interest of simplifying this explanation, only projector 1956 is described here in any detail. Referring to Fig.
- projector 1956 includes a housing (not separately labeled) that includes a top wall window 1955, a projector unit 1970 and a mirror 1972.
- Projector unit 1970 and mirror 1972 are arranged in the housing so that images projected by unit 1970 reflects off mirror 1972 and upward through window 1955 and generally behind credenza 1940 (i.e., to a side of the credenza opposite the side that doors 1944 face and to the rear of a rear edge of the top member 1946 and generally vertically upward there from into a space 1851 ).
- credenza 1940 i.e., to a side of the credenza opposite the side that doors 1944 face and to the rear of a rear edge of the top member 1946 and generally vertically upward there from into a space 1851 .
- the top member 1946 is glass, the images projected upward from projectors 1956 and 1956 pass through the top member.
- a rear surface of credenza 1940 opposite doors 1944 is generally against a flat wall, projected images appear on the wall surface.
- the projectors in credenza 1944 would only be used in at least some applications to provide slave images and that a master presentation unit akin to those described above would be used along with the credenza assembly 1940 to facilitate the methods described above.
- a master presentation unit akin to those described above would be used along with the credenza assembly 1940 to facilitate the methods described above.
- casters or wheels may be provided on the bottom of the credenza 1942 so that the credenza and components located therein could be moved from one location to other locations for use.
- a printer 1943 and other system components e.g., a master unit server or the like (not labeled) may be provided in space 1950.
- the glass top 1946 may comprise a polymer dispersed liquid crystal (PDLC) window or member that can be controlled to be either opaque or transparent.
- PDLCs operate on the principle of electrically controlled light scattering. They consist of liquid crystal droplets surrounded by a polymer mixture sandwiched between two pieces of conducting glass. When no electricity is applied the liquid crystal droplets are randomly oriented, creating an opaque state. When electricity is applied the liquid crystals align parallel to the electric field and light passes through the member creating a transparent state.
- the glass top 1946 may be deactivated so that the top member is opaque and the projectors and other components inside the space 1950 are hidden.
- a power transformer and a control switch are shown as 1841 in Fig. 72.
- the opacity controlling switch would be linked in some fashion to the master unit for control when slave images are required.
- the opacity controlled glass is described herein as a PDLC type glass, it should be appreciated that any type of electronically controlled glass assembly that has variable opacity may be employed.
- glass that has controllable opacity will generally be referred to as opacity controllable glass unless indicated otherwise.
- other furniture types are contemplated such as desks, tables, shelved, etc., that include controllable opacity glass for hiding and revealing projectors.
- an automatic scaling feature may be included as part of the master unit interface system wherein, as activities are performed that increase the size of an image beyond a size that will fit in an image space, the image size is automatically reduced to allow for additional application of information at the peripheral edges of the image.
- an exemplary master unit screen shot 2000 is shown that includes a workspace 1004 in which a master unit image is displayed.
- an invisible border or frame space along the edge of the workspace 1004 is shown by a dashed line 2002.
- the frame space may include the two inch space along each of the four sides of a displayed image.
- the image When the displayed image is altered such that altering activity causes information to be added to the frame space, the image may be shrunk so that the alterations can be shown.
- a pen icon 2004 is shown where a curve 2006 that is made on the master image extents into frame space indicated by line 2002 at a lower edge of the displayed image.
- the displayed image including the curve 2006a being added is shrunk and moved and the pen icon 2004 is also moved along with the curve 2006a.
- the shrunken image is moved to the center of the workspace 1004 so that information can be added around all four sides of the shrunken image.
- the shrunken image may be moved to some other location within workspace 1004 such as the upper left hand corner or the top center of the space.
- the shrunken image may be moved to the location within workspace 1004 that is most distant from the location at which an image altering activity entered the frame space 2002. For instance, referring again to Fig. 73 where curve 2006 entered space at the lower edge of workspace 1004, here, the shrunken image would be moved to be adjacent the top center edge of workspace 1004. Similarly, if a curve were made that entered space 2002 along the right hand edge of workspace 1004, the shrunken image may be moved to be relocated along the left center edge of workspace 1004. [0371] In at least some cases a dynamic resizing may occur.
- the image may be rescaled up to a larger image size (e.g., only 10% smaller than the original image size instead of 30% smaller) so that the largest image possible to accommodate an entire image can be provided automatically.
- the rescaling of the image may be performed in between changes to the image so that the rescaling does not adversely affect a system user's interaction with the image.
- the image may be resized up by 20% so that the largest possible image is provided automatically.
- reduction of image size may not occur immediately when activity enters the boundary space but may occur when a current activity ceases so that the shrinking activity does not result in discontinuous activity.
- the resizing may only occur after a stylus used to form the curve is lifted up.
- the desired curve may be completed within the frame space or the curve may continue back into the space within the frame boundary 2002 where the curve is completed. Once the stylus is lifted indicating the end to a current activity, the resizing may occur.
- immediate image repositioning may cause the immediate location of the pen icon to be misaligned with the activity that was being performed. For instance, referring again to Fig. 745, when the shrunken image 2008 is repositioned, while a user may be pointing a pen icon controlling stylus at location 2009, the curve 2006a would be moved up to the illustrated location so that a misregistration occurs. Here, to continue the curve, the user has to realign the icon controlling stylus with the tip of icon 2004.
- realignment with the tip of icon 2004 and hence with the end of curve 2006a may not be easy to perform given stylus position sensing capabilities of some master units.
- a realignment feature is contemplated wherein the master unit helps realign by slightly shifting a shrunken image when a realigning activity is attempted.
- a shrunken image 2012 is illustrated that is consistent with the discussion above regarding Figs. 73 and 74.
- a system user repositions a pen icon controlling stylus so that icon 2004 is located as shown with tip end 2016 near but separated (e.g., 2 inches) from the location of end 2014 of shrunken curve 2006a.
- the master unit senses the new location of icon 2004 and that the tip 2016 is located near end 2014, the unit may be programmed to assume that the user is attempting to realign the pen tip 2014 with the end 2014 of curve 2006a.
- the shrunken image 2012 may be shifted in its entirety so that curve end 2014 is located at the location of tip 2016 as illustrated in Fig. 2016 after which the user can proceed to complete curve 2006a as desired.
- a sticky notes feature may be included wherein conference attendees can add small proverbial "sticky notes” to session images that stay with images unless deleted or moved to other images.
- one additional icon 1809 in tool area 1002 is labeled "Note” which can be selected to add a note to an image currently displayed in the master unit workspace 1004.
- icon 1809 is selected, a note image is opened up 1803 on top of the currently displayed image in workspace 1004.
- the note 1803 can be moved around in workspace 1004 by selecting the note and dragging the note around the displayed image.
- Note 1803 can be closed by simply selecting a delete button 1813 that is associated with the note.
- note 1803 is opened and if the note is not deleted or moved to another image, the note remains associated with the image.
- Note 1803 can be moved to another image by selecting the note with a pointer icon and dragging the note like an object to a thumbnail of the other image located in tool area 1002.

- a pull down menu may be associated with each of the remote device icons 1805 in tool area 1002 which includes a notes option so that author specific notes can be accessed.
- a pull down menu may be associated with "Notes Summary" icon 181 1 that can be selected so that a range of dates/times can be specified over which notes should be accessed in a summary format.
- pre-canned session templates may be stored in a system database that can be accessed at the beginning of a session to place some structure on session images.
- a session template may include a single page that includes a company logo.
- the template may be provided each time a new image is generated so that all of the images in a session set include the logo or whatever else is included on the template. Thereafter the images may be altered in any of the ways described above.
- a template may include a plurality of pages (e.g., initial images) that are provided as the first or last pages in a session image set when a session is initiated.
- a company may want to enforce system rules wherein the first three pages of each session image set include standard session information such as a session title, a list of participants, session time and date information, participant time and date information, topics discussed, etc.
- an instance of a new session template may be opened that includes the three first pages and that either includes information gleaned by the master unit or that requires information to be added to the template by a user. Additional images generated during a session would initially be blank in this multiple page template example.
- a large number of single and multi-page templates may be supported by the system so that a user can select any of the different template types.
- Other template types are contemplated.
- the initial or final template image order cannot be altered so that the location of the session information within a set of session images cannot be modified.
- session images may be accessed, viewed and/or edited offline and then restored for subsequent on line access.
- a remote device user may log onto the server associated with a master unit, download a session including a plurality of images and then disconnect from the master unit server. Thereafter, the remote device user may be able to edit the session images in any of the ways described above using the remote device. After editing, the remote user can then re-access the master unit server and upload the edited session images for subsequent access during a conferencing session or for access by another remote device user for independent review and editing.
