Description

A PORTABLE DEVICE VVXTH VERSATILE KE'YrBOARDS
[0001] This application is a divisional application of Canadian Patent Application No. 2,545,811, filed November 19,2004.

FIELD
[00021 The present invention relates to portable electronic devices. More specifically, the invention relates to an electronic device with versatile keyboards that expose different key artangements and display orientations depending on which keyboard is deployed.

BACKGROUND
[0003] Portable electronic devices such as mobile phones, pagers, handheld computers, personal digital assistants ("PDA's") and hand-held gaming devices are becoming increasingly popular for both business and personal use. One advantage of these devices is their portabil_tty due to their sm.all size, light weight, battery--powcrcd or cordless operation and, in some cases, their wireless comniunications ability.
These features allow these portable electronic devices to be utilized whenever and wherever a user desires.
[0004] Because of the increasing popularity of these devices, however, it is not uncommon for a single user to carry more than one of these devices at one time. For example, a user may have a mobile phone and a two-way pager strapped to their belt, while carrying a PDA in a pocket and a gaming device in their bag. As such, having-separate devices perform each service or function creates a problem for a user who requires more than one or two services/functions offered by these portable devices.
[0005] - Designers have realized this probleni of device proliferation, and have tried to combine a number of services or functionalities into a single device. In this manner, a user may only require a single device having- a number of operational modes that correspond to a number of the desired services or functions. One drawback of incorporating many operational modes into a single device, however, is that each 7,4769-1380D

service or function typically has an established configuration, including the overall shape and the number and specific types of components. For example, a mobile phone generally includes a phone keypad consisting of 12 keys: I key each for the numbers 0-9, and a separate key for the "*" and "#" characters. Further, a mobile phone is generally oriented for use with its length extending in a vertical axis such that its display unit is positioned above the keypad and such that the alphanumeric or graplucal output of the display can be read by a user in this orientation. In contrast, a two-way pager typically includes an alphanumeric keyboard, such as a QWERTY keyboard that may include twice as many keys as a phone keypad. Further, a two-way pager typically has a display with a width greater than a length as viewed during use. In attenlpting to combine services/functionalities, a designer needs surface area onto which these established orientations and sets of components may be mounted. This increased demand for surface area competes with an overall goal of maintaining a device having a compact and portable size.
[0006] Thus, a portable electronic device having multiple layers of functional components is desired that provides for multiple functionalities while having a compact and portable size.

SUMMARY
[0007] The disclosed embodiments provide for a versatile user interface for an electronic device. In accordance with one aspect, the disclosed method provides for deploying one of a plurality of input means, detecting which one of the input means is deployed, and orienting information presented on the display based on the deployed input means.
[000s] In accordance with another aspect, the disclosed electronic device includes a first module layer movable in a first direction, a second module layer movably connected relative to the first module layer, and a third module layer movably connected relative to the second module layer and movable in a second direction.

2a [0008a] According to another aspect, there is provided a method for providing a versatile user interface for an electronic device, comprising: exposing a first set of functional components on a second module layer movably connected to a first module layer, where the first set of functional components is associated with a first operational mode of the electronic device; and exposing a second set of functional components on a third module layer movably connected to the second module layer, where the second set of functional components is associated with a second operational mode of the electronic device.

[0008b] According to another aspect, there is provided an electronic device capable of a first operational mode and a second operational mode, the electronic device comprising: a first module layer; a second module layer movably connected to the first module layer for exposing a first set of functional components associated with the first operational mode; and a third module layer movably connected to the second module layer for exposing a second set of functional components associated with the second operational mode.

[0009] Additional aspects and advantages of the disclosed embodiments are set forth in part in the description which follows, and in part are obvious from the description, or may be learned by practice of the disclosed embodiments.
The aspects and advantages of the disclosed embodiments may also be realized and attained by the means of the instrumentalities and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION
[0017] The disclosed embodiments include devices and methods for providing versatile keyboards for an electronic device. FIGs. 1-3 illustrate, in one embodiment, an electronic device 12, which has a number of movably interconnected module layers 14, 16, 18 that provide electronic device 12 with a number of functional capabilities. In one embodiment, for example referring to FIG. 1, electronic device 12 may have a first operational mode, such as a gaming mode, when module layers 14, 16, 18 are positioned in a first or neutral position where a first set of components 20 such as a display unit 22 and directional keypads 24, 26 on the exterior of electronic device 12 may be utilized. Referring to FIG. 2, electronic device 12 may have a second operational mode, such as a phone or audio communications mode, when first module layer 14 is moved in a first direction 28 relative to second and third module layers 16, 18 to expose a first additional set of conlponents 30, such as a phone keypad 31 and microphone 32, on second module layer 16. Further, referring to FIG. 3, electronic device 12 may have a third operational mode, such as a pager, PDA, or text communications mode, when third module layer 18 is moved in a second direction relative to first and second module layers 14, 16 to expose a second additional set of functional components 36, such as a QWERTY keyboard 38, on third module layer 18.
[0018] Although shown as including three layers, electronic device 12 may include any plurality of module layers that each may include one or more sets of functional components associated with one or more operational modes. The one or more operational modes enable device 12 to be utilized as one or more of: a mobile, satellite or wireless phone or audio communications device, a gaming device, a personal digital assistant ("PDA"), a pager or text communications device, a global positioning system ("GPS"), a remote control device for controlling another system, an audio player and/or recorder device such as an MP3 player or digital recorder, a static or dynamic video player and/or recorder device, a calculator device, etc. When utilized as a mobile phone, for example, device 12 may include hardware, software and/or firmware for sending and/or receiving communications-related signals using protocols such as a code division multiple access ("CDMA"), wide-band code division multiple access ("WCDMA"), global system for mobile communications ("GSM"), advance mobile phone service ("AMPS") and time division multiple access ("TDMA").
[0019] The one or more sets of components associated with each layer of device 12, such as module layers 14, 16, 18, may include one or more of plurality of types of functional components. These sets of components include external components, such as input and output type of mechanisms, and also intemal components such as circuit boards and circuit elements such as transistors, chips, firmware, memory, software and processing units configured for one or more operational modes of device 12.
For example, as mentioned above, first set of components 20 (FIG. 1) may include display 22, which includes any type of textual and/or graphical output unit such as a liquid crystal display, a light-emitting diode display, a touch screen, etc.
Directional keypads 24, 26 include toggle keys, navigation keys and other individual or multiple function keys associated with controlling movement of a graphic on display 22 or associated with creating an input signal to device 12.
[0020] First set of components 20 may also include other components such as:
an audio speaker 66 (FIG_ 1), such as a near-field and/or far-field speaker, for outputting audio signals; one or more indicator lights 68, 70 (FIG. 1) for signaling a status of the device 12; operational keys 72, 74 (FIG. 1) such as an on/off or hang-up key and a call accept/send key; volume keys 76 for increasing or decreasing a volume of a speaker such as near-field speaker 66; a push-to-talk button 78 (FIG. 2) for transmitting a voice signal in a walkie-talkie type phone mode; a record key 80 (FIG. 2) for activation a voice recorder functionality; a speaker/microphone input 82 (FIG. 2) for receiving a remote audio speaker and/or microphone connection mechanism; a camera mechanism for taking still or video pictures; a test port for connecting test or monitoring equipn7ent, such as radio frequency ("RF") signaling equipment, to set-up, repair or test device 12;
an infra red ("IR") transceiver for sending and/or receiving data via lR
waves; a battery pack for providing a cordless power source to device 12; a power/data connector for establishing a hard-wired connection to a source of power to operate device 12 and/or recharge the battery pack and to transmit and/or receive data; and an antenna mechanism 94 (FIG. 1) for transmitting and/or receiving communications signals associated with one or more of the modes of device 12.
[0021] Similarly, first and second set of additional components 30, 36 may include other functional components, such as any of the above-mentioned components, associated with a desired operational mode. It should be noted that the components associated with device 12 may be arranged in any combination, and on any layer, in order to achieve a desired configuration for each operational mode of device 12.
[0022] In operation, for example, the various operational modes of device 12 are controlled by the relative positioning of each layer of device 12. A method of controlling relative movement between these layers includes movably interconnecting various module layers to allow relative movement that exposes various functional components associated with each layer. Further, in order to provide a discrete actuation of an individual operational mode, the device further includes a locking mechanism that prevents movement between predetermined layers during actuation of predetermined modes.
[0023] In one embodiment, for example, referring back to FIGs. 1-3, the first operational mode of electronic device 12 may be activated by depressing one or a predetermined sequence of keys on the exterior of device 12. For example, the first operational mode may correspond to one or more of a gaming mode, a PDA mode, a camera mode, a GPS mode, a calculator mode, a data transfer mode and/or a phone stand-by mode. First set of components 20 may be utilized in various combinations to 74769-13$0D

achieve the desired functionality of this mode. For instance, when operated as a gaming device in this first mode, device 12 may be held such that its width is its longest dimension, and directional keypads 24, 26 are utilized for controlling gaming functions.
Additionally, associated with the actuation of this mode, device 12 may present the text and/or graphics output from display 22 in a predetermined orientation based on the selected operational mode. So, for example, the text/graphics in the gaming mode may be oriented 90 degrees relative to the text/graphics in a phone or PDA mode.
Further, first set of components 20 may simultaneously be functioning in more than one mode, such as in a phone stand-by mode, where upon receiving a phone call an output may be generated, such as by one or more of display 22, indicator lights 68, 70 and speaker 66.
A user may change device 12 into a phone mode by then sliding upper module layer 14 in first direction 28 or by accepting the call by depressing call accept key 74. In the PDA mode, a user may view data from display 22 and utilize any of the keys or buttons to produce inputs. Further, display 22 may be a touch screen display that allows additional inputs. In the camera mode, a user may operate the camera to take a still picture or a video, which may also allow the user to record any audio signals received by microphone 32 (FIG. 2) and associated with the picture or video. Further, in the data transfer mode, data may be received by or sent from device 12 through one or more of test port, IR transceiver, and power/data connector.
[0024] In one embodiment, a user activates a second operational mode, such as the phone mode (FIG. 2), by moving, e.g., sliding, upper module layer 14 in first direction 28 (vertical or upward), and exposing phone keypad 31. During this actuation step, the locking system prevents additional relative movement between the remaining layers that is associated with actuation of additional operational modes. In the phone mode, hardware, software and/or firmware within device 12 recognizes the actuation of this mode and orients the output of display 22 such that it is aligned for use in combination with phone keypad 31, e.g., in portrait. Further, device 12 actuates predetermined internal circuitry associated with the functionality of this mode, such as communications hardware and software for sending and receiving wireless signals. A user may communicate by talking into microphone 32 and by listening to speaker 66.
Further, additional phone-related functions may be performed via keystrokes on phone keypad 31 and send key 74, or by using directional keypad 24 or 26. This mode may be turned off, for example, by moving, e.g., sliding, upper module layer 14 back into the neutral position (FIG. 1) or by depressing the off key 72.

74769-13$0D

[0025] A user activates the pager or two-way text communications mode, referring to FIG. 3, by moving, e.g., sliding, lower niodule layer 18 in second direction (horizontal or sideway) and thereby exposing QIVERTY keyboard 38. During this actuation step, the locking system prevents additional relative movement between the remaining layers that is associated with actuation of additional operational modes. In this mode, hardware, software and/or firmware within device 12 recognizes the actuation of this mode and orient the output of display 22 such that it is aligned for use in combination with QWERTY keyboard 38, e.g., in landscape. Further, device 12 actuates predetermined internal circuitry associated with the fiuactionality of this mode, such as communications hardware and software for sending and receiving wireless signals. A user may communicate, for example, by reading received text messages output by display 22 or by entering characters from keyboard 38 and sending to another device via send key 74. This mode may be turned off, for example, by moving, e.g., sliding, lower module layer 18 back into the neutral position or by depressing the off key 72.
[0026] One way of sensing a keyboard movement is by using Hall Effect Sensors.
A
Hall Effect Sensor generates a voltage in relation to the movement of a magnetic field in close proximity to the sensor. The voltage is detected by the device and used as a sign of keyboard deployment. Benefits of using a Hall Effect Sensor are reliability and no mechanical elements to wear out over time.
[0027] Multiple applications may be running at the same time in device 12. The orientation of the infomnation presented on the display 22 generally may have a primary aspect ratio in relation to the direction of a keyboard deployment. There may be a secondary aspect ratio for each keyboard deployment direction. The aspect ratio control comprises user control and the various applications' control. The chart below indicates some of these relationships:

[0028] In the closed state (FIG. 1), the information presented on the display 22 may be presented in landscape or portrait as prescribed by the user, an application or both. In the phone state (FIG. 2), the orientation of information on the display 22 may be primarily controlled by an application operable with the phone key arrangenient in portrait with landscape as optional. In the QWERTY state (FIG. 3), the orientation of the information on the display 22 may be primarily controlled by an application operable with the QWERTY key arrangement and presented in landscape with portrait as optional. In one embodiment, to control the orientation of information on the display 22; thus, aclueving a versatile user interface, the user may select the desired orientation through a mechanical toggle switch located next to display 22.

[0029] Users may input information into the device in various ways. Users may provide input to device 12 through a touch sensitive display screen and/or voice recognition methods. Some of these various input means or user interfaces may be used to change orientation of the information on the display 22.

[0030] FIGs. 4 and 5 illustrate connection or sliding mechanisms 50, 52, 54, 56, which may form a portion of, or provide assistance to, the loclcing system. One or more connection mechanisms 50, 52, 54, 56 may be utilized to movably connect the module layers 14, 16, 18 such that the various relative movements are acluevable. For example, in one embodiment, connection mechazusms 50, 52 movably connect upper and middle module layers 14, 16 for relative movement in first direction 28, while connection mechanisms 54, 56 movably connect middle and lower module layers 16, 18 for relative movement in second direction 34. In this example, connection mechanisms 54, 56 may aid the locking system by preventing relative movement between middle and lower module layers 16, 18 in first direction 28 during relative movement of upper module layer 14 in that direction.

[0031] Connection mechanisms 50, 52, 54, 56 may include various types of magnetic connectors and mechanical connectors. In one embodiment, referring to FIG. 6 for example, connection mechanisms 50 or 52 or 54 or 56 include a can-ier body 58 movably connectable to a rail member 60 for movement along the length of the rail member. Carrier body 58 may be fixedly attached to one module layer 14, 16, 18, such as by mechanical or chemical fastening, while rail member 60 may be fixedly attached in a similar manner to the adjacent module layer to provide for the desired relative movement between layers. Referring to FIGs. 4 and 5, rail meinbers associated with connection mechanisms 50, 52 have a length extending parallel to first direction 28, 74769-13$0D

while rail members associated with connection mechanisms 54, 56 have a length extending parallel to second direction 34. As such, each carrier body 58 is movable in opposite directions along the length of each rail. As such, in this embodiment, the respective rail members and carrier bodies associated with connection mechanisms 50, 52, 54, 56 respectively provide the relative movement of upper and middle module layers 14, 16 to be substantially perpendicular to the relative movement of middle and.
lower module layers 16, 18. Although in this embodiment, connection members 50, 52, 54, 56 are represented as bi-directional sliding connectors, it should be noted that these connection members may provide movement along more than one axis, in more than one plane, and the movement may include linear and/or rotary sliding or flipping motion. Further, connection mechanisms 50, 52, 54, 56 may comprise metals, plastics, composites, and ceramics, and they may be formed integrally with each module layer 14, 16, 18 or separately attached via niechanical or chemical methods.
[0032] Thus, the described embodiments provide devices and methods for providing versatile keyboards for an electronic device, allowing different keyboard arrangements and -display orientations depending on which keyboard is deployed. While the various disclosed embodiments have been illustrated and described, it will be clear that the subject matter of this document is not limited to these embodiments only.
Numerous modifications, changes, variations, substitutions and equivalents will be apparent to those skilled in the art without departing from the spirit and scope of the disclosed embodiments as described in the claims.
