The present invention relates to display functions. More specifically, embodiments of the present invention relate to a method, system and device for controlling a display.
Modern computing, communicating, and other systems are used widely, in many fields and have many, often multiple applications. These systems include computers of various types, some of which are readily portable. For a variety of applications, portability can be a useful attribute and some computer and/or communicating systems that are portable may thus readily execute such applications and some in fact specialize in such applications.
For instance, personal digital assistants (PDAs), cellular telephones (cellphones), laptop, palmtop and other relatively small form factor computers typically perform a general variety of such applications. Further, a variety of portable computer systems are used with relatively specialized functions such as those relating to fields like surveying, construction, cartography, geodesics, agriculture and mining, etc. While some computer systems may not be especially portable, like their portable counterparts they perform a variety of useful applications.
Whether especially portable or not, many modern computer systems display information to their users. They display information on a variety of devices and components, which can use various technologies and media. Typical computer monitor devices include the cathode ray tube (CRT), an especially well-established technology, cold cathode or thin CRTs, thin film transistors, and liquid crystal display (LCD) devices, components, etc.
Small form factor, light weight, low power consumption, and other considerations can be desirable attributes of particular display devices or components for portable computing and/or communication systems. Thus, display devices or components for portable computer/communication systems tend to be relatively small in comparison for instance with many typical desktop computer monitors. Efficient use of display area is however generally beneficial for most display device/components.
Further, while perhaps efficiently designed for a specific function set, role, etc., where compared with substantially stationary systems such as desktop PCs and workstations, portable computers may have less processing and memory capacity and other more generalized computing resources and capability. For instance, while portable electronic surveying computer devices and cell phones are especially efficient at mapping and plotting surveying data, and at communicating and networking, respectively, their processors and memory capacity may be more limited that a variety of PCs. For portable and other computing/communication systems with such relatively limited available computing resources, display area use efficiency can thus also be significant.
With the relatively small displays and computing capability associated with portable computing systems, efficient use of their available display area can be a significant consideration for an application. In fact, whether a host computer system is readily portable or not, many applications can display information more effectively thereon where the application can make efficient use of a display device/component's available display area. Thus while some of the following discussion refers to an exemplary portable computer system/device, etc., this reference is exemplary. This reference exemplifies computer/communication systems in general, whatever their relative degree of portability.
An exemplary surveying application that is run on a computer platform may display a map. The map has a variety of features, which include a labeled graphical rendition or representation of a given geographical location, area, etc., hereinafter referred to as a “graphical geo-representation.” The map can also include various markers such as reference points, textual and symbolic annotations, surveying marker and/or reference points (e.g., related to a specific geographical location represented by the map's geo-representation), other symbols, text and the like.
These displayed markers are typically intended to provide to a user significant information relating to the map displayed, the application generating the display and/or the computer platform upon the display unit of which the map is rendered. Typically, these markers are superimposed on the graphical geo-representation. However, textual and symbolic information and/or graphical text and symbol fields corresponding to these markers can occlude and obfuscate each other, features of the geo-representation, and/or clutter, in some situations considerably, the graphical geo-representation.
The user may be confused by this clutter and obfuscation. The user may also be unable to visually access the obfuscated portions of the geo-representation. Further, the user may be unable to decipher displayed, perhaps significant textual information that is cluttered with other text, graphical field boxes and/or other displayed information.
Graphical clutter and obfuscation of a computer display such as is exemplified above is not an issue that is limited to map displays. In the display of webpages, text, images, portable and other documents and a variety of other graphics, graphical clutter and obfuscation such as is exemplified above can occur as well. Further, such graphical clutter and obfuscation is not an issue that limited to only surveying applications, nor to portable computing/communication devices.
Graphical clutter and obfuscation can confront an array of different applications that display information and can reduce the information display efficiency of desktop monitors, television screens of any type, including large screen, projection, and image wall types, as well as the relatively small display units typical of portable computer/communication devices.
Graphical clutter and obfuscation can interfere with and reduce an application's efficient display of information on a map or other graphical information rendition. Reduction in display efficiency can cause confusion, delay, and cost. Thus, graphical clutter and obfuscation can detract from the usefulness of an application and/or a computer/communication system display.
Accordingly, what is needed is a method, system and/or device for controlling a display which deters graphical clutter and obfuscation. What is also needed is a method, system and/or device for controlling a display, which supports an application's efficient display of information on maps and/or other graphical information renditions. Further, what is needed is a method, system and/or device for controlling a display which increases the usefulness of an application and deters confusion, and saves time and cost.
A method, system and device for controlling a display are disclosed. The method, system and device control the display so as to deter graphical clutter and obfuscation. Embodiments of the present invention also control displays so as to support an application's efficient display of information on graphical information renditions including maps, webpages, textually and/or graphically based or containing documents and others. Further, embodiments of the present invention control displays so as to increase the usefulness of an application, deter confusion, and save time and cost.
In one embodiment, data is examined, which correspond to an image to be shown with the display. Upon determining that said data comprise a critical item corresponding to an element of the image, the critical item is shown with an uncluttered view. Non-critical items corresponding to elements of the image are attempted to be shown as well, such that the critical item is not obscured and the image remains uncluttered.
A method, system and device for controlling a display are described. Reference is now made in detail to several embodiments of the invention, examples of which are illustrated in the accompanying drawing figures. While the invention will be described in conjunction with these embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims.
Furthermore, in the following detailed description of embodiments of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, one of ordinary skill in the art will realize that embodiments of the present invention may be practiced without these specific details. In other instances, well-known devices, circuits, methods, processes, procedures, systems, components, and apparatus, etc. have not been described in detail so as not to unnecessarily obscure aspects of the present invention.
Portions of the detailed description that follows are presented and discussed in terms of processes. Although steps and sequencing thereof are disclosed in figures herein (e.g.,
Embodiments of the present invention provide a method, system and device for controlling a display. In one embodiment, data is examined, which correspond to an image to be shown with the display. Upon determining that said data comprise a critical item corresponding to an element of the image, the critical item is shown with an uncluttered view. Non-critical items corresponding to elements of the image are attempted to be shown as well, such that the critical item is not obscured and the image remains uncluttered.
Therefore, a method, system and device for controlling a display are provided wherein graphical clutter and obfuscation, which can interfere with and reduce an application's efficient display of information on a map or other graphical information rendition, are deterred. Embodiments of the present invention support an application's efficient display of information on maps and/or other graphical information renditions. Embodiments of the present invention increase the usefulness of an application and deter confusion, and save time and cost.
Embodiments of the present invention are disposed to function with a computer and/or communication device, apparatus, system, etc. platform (referred to herein as computer/communication system”) which has an associated display devices, monitors, etc. Embodiments of the present invention are well suited to be practiced on a variety of such platforms including (but not limited to) laptops, PDAs, cellphones, surveying computers, geo-locating and mapping devices such as hand held GPS units, so called hand held, pocket and palmtop computers, desktop PCs, workstations, etc. Embodiments of the present invention allow such platforms to efficiently control a display. Embodiments of the present invention are well suited to control a variety of types of such displays including (but not limited to) thin film transistor array displays, LCDs, thin, cold cathode and other CRTs, etc., on relatively small displays, integrated with the computer/communication system or a separate monitor, television screen, etc.
Graphical imagery 111 corresponds to this geographic area, thus representing the area to the user visually in display 100, Such representational map imagery comprises a graphical geo-representation. Contour lines 112 and other features 113 allow geo-representation 111 to reveal elevations and other geographic and other features that may characterize the represented geographical area.
A variety of points 114 on geo-representation 111 are added to display 100 automatically and/or with user action. The points 114 allow the user of map 110 to mark positions, stakes, features and the like which correspond to some geographic location, survey point, etc. of particular interest. Those of points 114 that are especially significant to a user can be flagged as critical points. One such significant point for instance can represent the starting point of a survey, expedition, etc., such as the point marked (and arranged) as:
(in the ‘L’ shaped field near the lower left hand corner of cursor 107).
Fields 115 each correspond to one of points 114. Fields 115 are displayed proximate to each of their respective points 114. Fields 115 display to the user textual, symbolic, and/or other information relating to each of their respective corresponding points 114. For instance, text and/or other symbols within fields 115 label, name, describe, etc. their respective points 114 and/or geographic features proximate thereto.
A set of functional graphical user interface (GUI) display features 101-106 are arrayed in a convenient location such as a side or other border of display 100. Display features 101-106 allow the user to interactively interface with the display 100. For instance, display feature 101 can be actuated to allow the user to move a cursor 107. Display feature 102 and 103 can be activated to each change the size of the portion of represented geographic area depicted with map 110 or selected with (e.g., bounded graphically with) cursor 107, such as to respectively zoom in or out (e.g., effectively changing in either direction the boundaries of the displayed information within cursor 107 or map 110), call for display of markers applicable thereto, etc. Display feature 104 allows a portion of the display to be visually changed so as to render it more legible, viewable, etc. Thus, display feature 104 effectively functions as a display graphics virtual magnifier.
While map 110, as depicted in the screen shot of
In fact, as seen in several regions of map 110 here, text or text fields 115 occlude and obfuscate other text or text fields 115, rendering much of the text illegible or parts of fields 115 occluded, e.g., in the region surrounding cursor 107. Even where critical points are marked, significant information about them such as their label and/or name can be effectively unavailable, legibly, to a user. For instance, the label corresponding to the critical point
referred to above is occluded and rendered substantially illegible by the cluttered text in and around the cursor 107.
The result is seen in the screen shot of
Such graphical data can comprise a map, a webpage, a document, a picture, etc. that is to be displayed on a display unit associated with a computer/communicating system. In one embodiment, such data is accessed with a display control tool from the graphics display interface (GDI) or a similarly functional graphics related application program interface (API) of an operating system (OS) running on a processor of the computer/communicator.
In step 32, it is determined whether these data comprise any critical items, the display of which is especially significant for the image being displayed. If so, in step 33, fields corresponding to the critical items are generated, graphically arranged so as to be shown uncluttered (e.g., with no clutter).
In one embodiment, items in the display are either critical or non-critical. In examining the data corresponding to an image to be displayed, criticality is assigned to an item based on its significance to the application that is showing the display. For instance, in an application related to surveying, geodesics, cartography and the like, points such as an ‘occupy point’, a ‘backsight point’, ‘GPS control points’ and others are, under some circumstances, assigned criticality for display. In a graphical creativity application, under some circumstances points such as ‘anchor point’, ‘center point’ and ‘focus point’ are assigned criticality. In a word processing application, points assigned criticality under some circumstances include points of editorial and drafting significance. Other applications assign criticality to display items based on criteria and parameters significant to that application.
In step 34, the critical items are shown with an uncluttered view (e.g., so that they are not obscured, occluded, or obfuscated with another critical item or with any other item on the display).
Upon showing the critical items free of clutter (or if no critical items were to be displayed), it is determined in step 35 whether any other (e.g., other than critical) items remain to be displayed. If so, in step 36, the remaining items are displayed with no clutter, wherein the remaining items are graphically arranged so that they do not obscure, occlude, or obfuscate any critical item or any other item on the display, including each other. In one embodiment, where a non-critical item cannot be shown without cluttering the image, such as wherein a view of a critical item's field is obscured, occluded, or obfuscated with the non-critical item, the non-critical item is withheld from being shown.
In one embodiment, the critical and non-critical items comprise region objects associated with the GDI of an OS. Exemplary OS platforms with which various embodiments of the present invention can function include, but are not limited to, Windows™ (e.g., WindowsCE™, Microsoft Pocket PC™, Windows Mobile™, Windows Mobile for Smart Phones™; all commercially available from Microsoft, a corporation in Redland, Wash.). Other platforms with which various embodiments of the present invention can function include non-Windows based OSs and those available from elsewhere, than as named above.
The resulting image of graphical data, such as the map, are then displayed in step 37 in such a way that all graphical items displayed are shown uncluttered, unobscured, unoccluded, and not obfuscated.
For instance, significant points such as the critical point 114, with its associated label 115, a text field labeled as described above:
However, as shown in
Display drivers 517 graphically write data 508 corresponding to an image on display unit 516, as directed with GDI (or other similarly functional graphics API) 518 of OS 519. Information 509 relating to these data is accessed with an image modeling and labeling tool 510. In one embodiment, information 509 includes region objects associated with GDI 518.
Display evaluation module 511 evaluates information 509 and flags certain of them as relating to a critical point, e.g., in the image to be displayed. Other data are identified as corresponding to non-critical points.
Image uncluttering module 512 handles these evaluated data 507, e.g., with respect to their criticality and prioritizes their display related processing such that critical display data are given relatively greater space priority than non-critical display data.
Image label generator module 513 handles these prioritized data 506 and formats them for efficient graphical presentation, according to their priority. Where they cannot be displayed without causing clutter (e.g., obscuring, occluding, and/or obfuscating a critical item or another (e.g., already selected) non-critical item, certain non-critical items will be remembered (e.g., for later viewing, dropping permissions, etc.), but their instant display are effectively suppressed, e.g., system 500 withholds them from being displayed.
GDI 318 accesses these graphically formatted data 505 and directs display drivers 517 according to their format. The corresponding graphical image displayed with display unit 516 is free of clutter.
Process 600 begins with step 601, wherein a list is generated of points to label and display. In step 602, a ‘Used Label’ master region is created, which represents the graphical area (e.g., maps to the image to be) displayed. In one embodiment, this master region is initially empty (e.g., devoid of data to e displayed).
In step 603, a point to be labeled is selected. In one embodiment, critical points are selected with priority over points that are other than critical. A point comprises a symbol, which corresponds to (e.g., represents, symbolizes, etc.) one of various features that characterize the graphical image to be displayed. For instance, where the graphic to be displayed comprises a map, points correspond to geographical locations, navigational fixes, coordinates corresponding to a geographical position, etc.
In step 604, process 600 attempts to label (e.g., generate a corresponding labeling text field for potential display with) the selected point to one of its sides. In one implementation, process 600 attempts to label the point to its right side (e.g., as it is displayed, formatted for display, etc.) of the point.
In step 605, a ‘point label’ region is generated, which corresponds to this label, to the selected, e.g., right side of the point. In step 606, the generated point label region is subjected to a logical ‘AND’ operation together with the ‘used label’ master region.
In step 607, the resulting developing graphical display precursor is evaluated to determine whether there is any overlap between regions. If regions do not overlap, then in step 608, process 800 commits to room existence, e.g., within the display area, to display the selected point and e.g., its corresponding label.
In step 609, the ‘point label’ region is subjected to a logical ‘OR’ operation with the ‘used label’ master region. In step 610, the point label is displayed (e.g., added to the developing display data, etc.) and data relating to the ‘used label’ master region is correspondingly updated.
In step 611, it is determined whether there are additional points to be displayed. If not, then in step 612, the graphical representation formed is displayed. For instance, where the graphic comprises a map, the graphical geo-representation is displayed with the selected point and its corresponding label to generate the map. Process 600 can be complete at this point.
However, where an overlap between regions was determined to exist in step 607, process 600 proceeds with step 613, wherein an attempt is made to label the selected point to its side opposite to that first selected (e.g., in step 604). Thus, in the present exemplary implementation, in step 613 an attempt is now made to label the point to its left side.
In step 614, a ‘point label’ region is generated, which corresponds to this label, to the left side of the point. In step 615, the generated point label region is subjected to a logical ‘AND’ operation together with the ‘used label’ master region.
In step 616, the resulting developing graphical display precursor is evaluated to determine whether there is any overlap between regions. If regions do not overlap, then process 600 proceeds with step 608, which is described above. If however it is determined that no room exists to display the selected point, e.g., without cluttering the display, obscuring, occluding, and/or obfuscating another point or its label, then in step 617 process 600 commits to insufficient room existence to display the selected point, its corresponding label, etc. and proceeds with step 611, as discussed above.

In various embodiments, display types (e.g., technologies, etc.) are unique with respect to other embodiments. In various embodiments, display 701 comprises thin film transistor array displays, LCDs, thin, cold cathode and other CRTs, and other types. Display 701 provides graphical, visual, etc. information to a user such as images, e.g., comprising pixels, etc. and achieves effective resolution, chrominance, luminance, etc., and in some implementations may be reflective, backlit, etc. In one implementation, display 701 comprises a lightweight, low power consumption, etc. display device.
