DETAILED DESCRIPTION OF THE DRAWINGS
An example embodiment of the present invention and its potential advantages are understood by referring to FIGS. 1 through 7 of the drawings.
In an example embodiment, an apparatus displays a visual representation relating to at least one information item. An information item may relate to a program, a file, image information, audio information, video information, setting information, a directory, a folder, a playlist, and/or the like. For example, an information item may relate to a game. In another example, an information item may relate to a song. In still another example, an information item may relate to a setting for an email account.
A visual representation relating to an information item may comprise graphical information, textual information, video information, and/or the like. For example, a visual representation of an information item may comprise an icon. In another example, a visual representation of an information element may comprise text denoting a program name. In yet another example, a visual representation of an information item may comprise text and an icon.
A visual representation of more than one information item may comprise an arrangement of visual representations of the information items. For example, a visual representation of more than one information item may comprise a one dimensional representation of information items, such as a list, a two dimensional representation, such as a grid, a three dimensional representation, such as a room, and/or the like. For example, a visual representation of more than one information item may represent each information item as text, where text associated with the information items are arranged vertically or horizontally. In another example, a visual representation of more than one information item may represent each information item as an icon, where the icons are arranged vertically and horizontally.
In an example embodiment, an information item may have at least one additional information item associated with it. For example, an information container, such as a directory, a folder, a playlist, a control panel, and/or the like, may be an information item that has associated information items that have a containment relationship with the information container. It should be understood that a containment relationship may be independent of storage topology. For example, a directory may have file information items associated with it based on their containment within the directory. In another example, a playlist may have audio information items associated with it based on their containment relationship with the playlist. In still another example, a control panel may have setting information items associated with it based on their containment relationship with the control panel.
In another example, the information item may have at least one additional information item associated with it based on a non-containment relationship. For example, a program may have information items associated with it representing information that the program uses. In such an example, a media player program may have a playlist information item, an audio information item, a video information item, and/or the like, associated with it.
In an example embodiment, a user may be able to view a visual representation of additional information items associated with an information item. For example, the user may view a visual representation of additional information items having a containment relationship with an information container. The apparatus may display the visual representation of the additional information items in relation to the visual representation of the information item. For example the visual representation of the additional information items may overlay the visual representation of the information item, be adjacent to the visual representation of the information item, and/or the like.
In an example embodiment, a user may be able to control the visual representation of additional information items associated with an information item. For example, a user may perform a drag input, such as input 620 of FIG. 6B, where the contact input, such as contact input 622, relates to the information item. In such an example, the contact input may have a similar position to the visual representation of the information item. The user may be able to control the number of additional information items, the size of the visual representation of the additional information items, and/or the like. For example, the distance of a drag input may determine, at least in part, the number of additional information items to represent. In another example, the distance of the drag input may determine, at least in part, the size of the visual representation of the additional information items. The direction of the movement of the input may vary. For example, the direction of an input movement, such as movement 624 of FIG. 6B, may be vertical, horizontal, diagonal, and/or the like.
In an example embodiment, the position of the visual representation of the additional information items may vary. For example, the position of the visual representation of the additional information items may be adjacent to, on top of, and/or the like, the related information item. In an example embodiment, the position of the visual representation may vary based, at least in part on the position of the visual representation of the information item. For example, if the visual representation of the information item is located at the left side of the display, the visual representation of the additional information items may be to the right of the information item. In another example, if the visual representation of the information item is located at the bottom of the display, the visual representation of the additional information items may be above the information item.
FIGS. 1A-1C are diagrams illustrating a visual representation of information items according to an example embodiment of the invention. Although the examples of FIGS. 1A-1C illustrate a two dimensional grid visual representation, the arrangement of the visual representation may vary across embodiments and do not limit the scope of the invention. Even though the examples of FIGS. 1B-1C illustrate an overlay of the visual representation of the additional information items, the orientation of the visual representation of the additional information items may vary and does not limit the scope of the invention. Furthermore, although the overlay of FIGS. 1B and 1C illustrate a non-transparent overlay, the style of overlay may vary. For example, the overlay may be transparent, semi-transparent, solid, and/or the like.
FIG. 1A is a diagram illustrating a visual representation of information items 100 according to an example embodiment of the invention. Blocks 102-124 each represent a visual representation of an information item.
FIG. 1B is a diagram illustrating a visual representation of information items 130 overlaid with a visual representation of additional information items 132.

Additional information items of visual representations 150 and 152 may relate to the information item of visual representation 134. For example, information items of visual representations 150 and 152 may be files with a containment relationship to the information item of visual representation 134. In the example of FIG. 1B, the user may have performed a drag input, a continuous stroke input, a multiple touch input, and/or the like, where the distance associated with the input corresponds to a determination to visually represent 2 additional information items associated with the information item of visual representation 134. In such an example, the user may have performed a drag input, for example drag input 620 of FIG. 6B, having a contact input related to the information item of visual representation 134 and a short movement input.
FIG. 1C is a diagram illustrating a visual representation of information items 160 overlaid with a visual representation of additional information items 162. Blocks 164-178 each relate to a visual representation of an information item. Blocks 180-190 relate to visual representations of additional information items. Additional information items of visual representations 180-190 may relate to the information item of 164. For example, information items of visual representations 180-190 may be information items related to information item 164. In the example of FIG. 1C, the user may have performed a drag input, a continuous stroke input, a multiple touch input, and/or the like, where the distance associated with the input corresponds to a determination to visually represent 6 additional information items associated with the information item of visual representation 164. In such an example, the user may have performed a multiple touch input, for example input 680 of FIG. 6E, having contact input related to the information item of visual representation 164 and a long movement input.
FIGS. 2A-2C are diagrams illustrating a visual representation of information items according to an example embodiment of the invention. Although the examples of FIGS. 2A-2C illustrate a 2 dimensional grid visual representation, the arrangement of the visual representation may vary across embodiments and does not limit the scope of the invention. Even though the examples of FIGS. 2B-2C illustrate an overlay of the visual representation of the additional information items, the orientation of the visual representation of the additional information items may vary and does not limit the scope of the invention. Furthermore, although the overlay of FIGS. 2B and 2C illustrate a non-transparent overlay, the style of overlay may vary. For example, the overlay may be transparent, semi-transparent, solid, and/or the like.
FIG. 2A is a diagram illustrating a visual representation of information items 200 according to an example embodiment of the invention. Blocks 202-224 each represent a visual representation of an information item.
FIG. 2B is a diagram illustrating a visual representation of information items 230 overlaid with a visual representation of additional information items 232. Blocks 234-252 each relate to a visual representation of an information item. Blocks 254 and 256 relate to visual representations of additional information items. Additional information items of visual representations 254 and 256 may relate to the information item of visual representation 234. For example, information items of visual representation 254 and 256 may be files with a containment relationship to the information item of visual representation 234. In the example of FIG. 2B, the user may have performed a drag input, a continuous stroke input, a multiple touch input, and/or the like, where the distance associated with the input corresponds to a determination to visually represent additional information items associated with the information item of visual representation 234, with a visual representation having the size of visual representation 232. In such an example, the user may have performed a drag input, for example input 620 of FIG. 6B, having a contact input related to the information item of visual representation 234 and a short movement input.
FIG. 2C is a diagram illustrating a visual representation of information items 260 overlaid with a visual representation of additional information items 262. Blocks 264-278 each relate to a visual representation of an information item. Blocks 280-290 relate to visual representations of additional information items. Additional information items of visual representation 280-290 may relate to the information item of visual representation 264. For example, information items of visual representation 280-290 may be information items related to the information item of visual representation 264. In the example of FIG. 2C, the user may have performed a drag input, a continuous stroke input, a multiple touch input, and/or the like, where the distance associated with the input corresponds to a determination to visually represent additional information items associated with the information item of visual representation 264, with a visual representation having the size of visual representation 262. In such an example, the user may have performed a multiple touch input, for example input 680 of FIG. 6E, having contact input related to the information item of visual representation 264 and a long movement input.
In an example embodiment, the apparatus may modify the representations of additional information items. For example, the apparatus may reduce the size of the representations of information items, thus showing more information items using less space.
FIG. 3 is a flow diagram showing a method 300 for displaying additional information items according to an example embodiment of the invention. An apparatus, for example electronic device 10 of FIG. 7, may utilize method 300.
At block 302, the apparatus receives a touch input, for example input 640 of FIG. 6C, associated with an information item. The touch input may comprise position information, time information, speed information, and/or the like. A touch display, for example display 28, of FIG. 7, may receive the continuous stroke input. The apparatus may receive the touch input after the touch input terminates, before the touch input terminates, and/or the like. For example, the apparatus may receive the touch input while a user is performing the touch input. In another example, the apparatus may receive the touch input after the user has terminated a touch input. Termination of a touch input may relate to a release input, for example release input 646 of FIG. 6C, the movement of the touch input intersecting with a region of the display associated with termination, the movement of the touch input intersecting with a display boundary, and/or the like. The position of the touch input may associate the touch input with the information item. For example, a user may perform a drag input, such as input 620 of FIG. 6B, where the position of the contact input, such as contact input 622 relates to the position of the visual representation of the information item, for example visual representation 134 of FIG. 1B.
At block 304, the apparatus determines a set of at least one additional information item associated with the information item, based at least in part on the touch input. The number of additional information items of the set may be based, at least in part, on the distance of the movement of the input, the speed of the movement of the input, and/or the like. For example, a long movement may relate to a set comprising many additional information items. In another example, a short movement may relate to a set comprising few additional information items. The relationship between the information item and the additional information items may be a containment relationship, a usage relationship, and/or the like. For example, an information item may be a control panel, while the additional information items may be settings. In another example, the information item may be a program, and the additional information items may be files used by the program. In such an example, the program may be a word processor, and the files may be documents. The determination of which additional information items to include in the set may be based on the content of the additional information item, usage information associated with the additional information item, and/or the like. For example, the apparatus may determine that the set comprises the most recently used additional information items. In another example, the apparatus may determine that the set comprises the additional information according to a predefined arrangement, such as a user arrangement, default arrangement, and/or the like. In an example embodiment, the apparatus may determine a subset of the set. For example, the apparatus may determine a subset capable of being displayed in a predefined area.
At block 306, the apparatus generates a visual representation, for example visual representation 262 of FIG. 2C, based at least in part on the set. The visual representation of the set may comprise a visual representation of the at least one additional information item. The size of the generated visual representation may be predetermined, may vary in relation to the received input, may vary in relation to the size of the set, and/or the like. For example, the size of the generated visual representation may be a predetermined size regardless of the number of additional information items, such as visual representation 132 of FIG. 1B. In another example, the size of the generated visual representation may be determined by the number of additional information items in the set, such as visual representation 232 of FIG. 2B. The visual representation may comprise an indication of the number of additional information items represented. For example, the visual representation may comprise a ratio representation, such as at least one number, a graph, a bar, and/or the like. The ratio representation may indicate the number of additional information items represented in relation to the number of additional information items associated with the information item.
At block 308, the apparatus displays the generated visual representation. The apparatus may position the display of the visual representation in relation to the position of the visual representation of the information item. For example, the generated visual representation may be adjacent to the visual representation of the information item, such as visual representation 132 associated with the information item of visual representation 134 of FIG. 1B. The apparatus may display the generated visual representation according to various display styles. For example, the apparatus may display the generated visual representation as an overlay, a frame, a window, and/or the like. In another example, if the apparatus displays the generated visual representation as an overlay, the background of the generated visual representation may be semi-transparent so that at least part of the overlain image may be seen.
In an example embodiment, an apparatus may display a visual representation of additional information items as the user performs a touch input. For example, a user may have performed a contact input, such as contact input 622 of FIG. 6B, and be performing a movement input, such as movement input 624 of FIG. 6B. During the movement input, the apparatus may generate the set of additional items based at least in part on the movement input at the time of set generation. For example, if a user is performing movement associated with increasing the number of additional information items in the set, the apparatus may generate a first set with a number of additional information items, and a second set with a larger number of additional information items, after the movement input indicates generating a larger set. In another example, if a user is performing movement associated with decreasing the number of additional information items in the set, the apparatus may generate a first set with a number of additional information items, and a second set with a lesser number of additional information items, after the movement input indicates generating a smaller set. In this manner, the apparatus may vary the visual representation of the set of additional information items displayed in accordance with the ongoing receipt of input.
FIG. 4 is a flow diagram showing another method 400 for displaying additional information items according to an example embodiment of the invention. An apparatus, for example electronic device 10 of FIG. 7, may utilize method 400.
At block 402, the apparatus receives a touch input, for example input 620 of FIG. 6B, associated with an information item. The reception, the input, the association, and the information item are similar as described with reference to block 302 of FIG. 3.
At block 404, the apparatus determines a first set of at least one additional information item associated with the information item, based at least in part on the touch input. The determination, the set, and the additional information item are similar as described with reference to block 304 of FIG. 3.
At block 406, the apparatus generates a first visual representation, for example visual representation 132 of FIG. 1B, based at least in part on the first set. The generation and the visual representation are similar as described with reference to block 306 of FIG. 3.
At block 408, the apparatus displays the first visual representation. The displaying is similar as described with reference to block 308 of FIG. 3.
At block 410, the apparatus determines a second set of at least one additional information item associated with the information item, based at least in part on a change in the touch input. The determination, the set, and the additional information item are similar as described with reference to block 304 of FIG. 3. The change in the touch input may relate to a change in position, time, speed, and/or the like, such as a change in distance from a contact input, such as contact input 622 of FIG. 6B.
At block 412, the apparatus generates a second visual representation, for example visual representation 162 of FIG. 1C, based at least in part on the second set. The generation and the visual representation are similar as described with reference to block 306 of FIG. 3.
At block 414, the apparatus displays the second visual representation. The displaying is similar as described with reference to block 308 of FIG. 3. In an example embodiment, the apparatus terminates the display of the first visual representation when displaying the second visual representation.
In an example embodiment, an apparatus may terminate the display of the visual representation of the set of additional information items. For example, the apparatus may terminate displaying the visual representation of the set when a user selects an additional information item in the set. In such an example, the user may select the additional information item by performing a tap input, a drag input, a release input, and/or the like, in relation to the additional information item. In another example, the apparatus may terminate displaying the set when it receives a release input. In such an example, the apparatus may display the visual representation of the set only while the user is touching the screen. In another example, the apparatus may terminate displaying the visual representation of the set after the elapse of an amount of time. In such an example, the apparatus may terminate displaying the visual representation of the set after 3 seconds. In another example, the apparatus may terminate displaying the visual representation of the set after the user has performed a release input, such as release input 624 of FIG. 6B, and after the elapse of an amount of time. In such an example, the apparatus may terminate displaying the visual representation of the set 3 seconds after the user performs a release input.
FIG. 5 is a flow diagram showing a still another method 500 for displaying additional information items according to an example embodiment of the invention. An apparatus, for example electronic device 10 of FIG. 7, may utilize method 500.
At block 502, the apparatus receive a touch input, for example input 620 of FIG. 6B, associated with an information item. The reception, the input, the association, and the information item are similar as described with reference to block 302 of FIG. 3.
At block 504, the apparatus determines a set of at least one additional information item associated with the information item, based at least in part on the touch input. The determination, the set, and the additional information item are similar as described with reference to block 304 of FIG. 3.
At block 506, the apparatus generates a visual representation, for example visual representation 232 of FIG. 2B, based at least in part on the set. The generation and the visual representation are similar as described with reference to block 306 of FIG. 3.
At block 508, the apparatus displays the visual representation. The displaying is similar as described with reference to block 308 of FIG. 3.
At block 510, the apparatus terminates displaying the visual representation. The apparatus may terminate the display of the visual representation based, at least in part, on a release input, for example, release input 646 of FIG. 6C, a selection of an additional information item, an elapse of time, and/or the like. The termination of the displaying of the visual representation may comprise removing the visual representation from the display.
FIGS. 6A-6D are diagrams illustrating input from a touch display, for example from display 28 of FIG. 7, according to an example embodiment of the invention. In FIGS. 6A-6D, a circle represents an input related to contact with a touch display, two crossed lines represent an input related to releasing a contact from a touch display, and a line represents input related to movement on a touch display.
In the example of FIG. 6A, input 600 relates to receiving contact input 602 and receiving a release input 604. In this example, contact input 602 and release input 604 occur at the same position. In an example embodiment, an apparatus utilizes the time between receiving contact input 602 and release input 604. For example, the apparatus may interpret input 600 as a tap for a short time between contact input 602 and release input 604, as a press for less short time between contact input 602 and release input 604, and/or the like. In such an example, a tap input may induce one operation, such as selecting an item, and a press input may induce another operation, such as performing an operation on an item.
In the example of FIG. 6B, input 620 relates to receiving contact input 622, a movement input 624, and a release input 626. In this example, contact input 622 and release input 626 occur at different positions. Input 620 may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input 620 based at least in part on the speed of movement 624. For example, if input 620 relates to panning a virtual screen, the panning motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input 620 based at least in part on the distance between contact input 622 and release input 626. For example, if input 620 relates to a scaling operation, such as resizing a box, the scaling may relate to the distance between contact input 622 and release input 626.
In the example of FIG. 6C, input 640 relates to receiving contact input 642, a movement input 644, and a release input 646 are shown. In this example, contact input 642 and release input 646 occur at different positions. Input 640 may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input 640 based at least in part on the speed of movement 644. For example, if input 640 relates to panning a virtual screen, the panning motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input 640 based at least in part on the distance between contact input 642 and release input 646. For example, if input 640 relates to a scaling operation, such as resizing a box, the scaling may relate to the distance between contact input 642 and release input 646.
In the example of FIG. 6D, input 660 relates to receiving contact input 662, and a movement input 664, where contact is released during movement. Input 660 may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input 660 based at least in part on the speed of movement 664. For example, if input 660 relates to panning a virtual screen, the panning motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input 660 based at least in part on the distance associated with the movement input 664. For example, if input 660 relates to a scaling operation, such as resizing a box, the scaling may relate to the distance of the movement input 664 from the contact input 662 to the release of contact during movement.
In the example of FIG. 6E, input 680 relates to receiving contact inputs 682 and 688, movement inputs 684 and 690, and release inputs 686 and 692. In this example, contact input 682 and 688, and release input 686 and 692 occur at different positions. Input 680 may be characterized as a multiple touch input. Input 680 may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input 680 based at least in part on the speed of movements 684 and 690. For example, if input 680 relates to zooming a virtual screen, the zooming motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input 680 based at least in part on the distance between contact inputs 682 and 688 and release inputs 686 and 692. For example, if input 680 relates to a scaling operation, such as resizing a box, the scaling may relate to the collective distance between contact inputs 682 and 688 and release inputs 686 and 692.
