Abstract

A computer program product having a computer readable medium having computer program logic recorded thereon comprises code for generating a canvas upon a display space, the canvas being larger than the display space and including an interactive element, code for navigating within the canvas upon the display space code for changing a status of the interactive element in response to navigation moving the interactive element within the display space.

Claims

1. A computer program product having a non-transitory computer readable medium having computer program logic recorded thereon, the computer program product comprising:

code for generating a canvas upon a display space, the canvas being larger than the display space and comprising an interactive element; and

code for changing a status of the interactive element in response to movement-of-the interactive element within the display space, wherein changing the status of the interactive element comprises;

causing the interactive element to transition from invisible, to translucent, to opaque as the canvas shifts, and

causing the interactive element to change from unselectable to selectable as the interactive element transitions from translucent to opaque.

2. The computer program product of claim 1 wherein the code for changing a status of the interactive element comprises:

code for applying a visual transformation to the interactive element.

3. The computer program product of claim 2 wherein the visual transformation comprises a gradual change in appearance of the interactive element.

4. The computer program product of claim 2 wherein the visual transformation is applied as the interactive element approaches a center of the display space during navigation.

5. The computer program product of claim 2 wherein the visual transformation comprises at least one of the following:

a gradual change in size of the interactive element; and

a gradual rotation of the interactive element.

6. The computer program product of claim 1 wherein the display space comprises at least one of the following:

a screen of a handheld device; and

a screen of a desktop computer.

7. The computer program product of claim 1 wherein the code for changing a status of the interactive element comprises:

code for making the interactive element selectable.

8. The computer program product of claim 1 wherein the code for code for changing a status of the interactive element comprises:

code for selecting the interactive element.

9. The computer program product of claim 1 wherein the interactive element comprises an item selected from the list consisting of:

an icon;

a small collection of user interface components that work together;

a window; and

a single user interface component.

10. The computer program product of claim 1 wherein the canvas is three-dimensional.

11. The computer program product of claim 1 wherein the canvas includes a plurality of other interactive elements.

12. The computer program product of claim 1 further comprising:

code for inserting the interactive element into the canvas in response to input; and

code for expanding the canvas in response to inserting the interactive element.

13. The computer program product of claim 1 wherein during navigation the interactive element is visible but non-selectable within a first portion of the display space and visible and selectable within a second portion of the display space.

14. The computer program product of claim 1 wherein the canvas comprises:

a virtual display area on which the interactive element is placed.

15. A method performed upon a processor-based device with a display screen, the method comprising:

rendering a canvas upon the display screen, the canvas being larger than the display screen and including an interactive element;

moving the canvas relative to the display screen; and

changing an activity status of the interactive element as the interactive element is moved, wherein said changing activity status includes monitoring proximity of the interactive element with respect to the display screen and changing the activity status of the interactive element when a specified portion of the interactive element crosses a pre-defined proximity threshold, wherein changing the activity status of the interactive element comprises;

transitioning the interactive element from invisible, to translucent, to opaque as the canvas moves, and

changing the interactive element from unselectable to selectable as the interactive element transitions from translucent to opaque.

16. The method of claim 15 further comprising:

changing a visual appearance of the interactive element as the activity status is changed.

17. The method of claim 15 wherein changing an activity status comprises one or more of:

transforming from an icon to an active application; and

transforming from a tile to an active application.

18. The method of claim 15 wherein the canvas is moved in response to user input received through input means of the processor-based device.

19. The method of claim 15 wherein the activity status of the interactive element is changed in response to the interactive element approaching an area of the display screen.

20. The method of claim 15 wherein, during navigation, the interactive element is on the display screen and is in a non-selectable state, the interactive element changing to a selectable state as it approaches a portion of the display screen.

21. A handheld, processor-based device comprising:

a screen having a display area, the screen displaying a canvas, the canvas being larger than the display area;

an interactive element on the canvas; and

wherein the processor is operable for dynamically causing the interactive element to change its executable status in response to its proximity to a first portion of the display area during movement of the canvas wherein changing the interactive element'"'"'s executable status comprises transitioning the interactive element from invisible, to translucent, to opaque as the canvas shifts and changing the interactive element from unselectable to selectable as the interactive element transitions from translucent to opaque.

22. The handheld, processor-based device of claim 21 further comprising:

interface means for receiving input, wherein the processor transforms the received input into movement of the canvas relative to the display area.

23. The handheld, processor-based device of claim 21 wherein the interactive element is visible but not selectable within a second portion of the display area.

24. The handheld, processor-based device of claim 21, wherein the screen comprises a touchscreen.

25. A personal computer comprising:

a screen having a display area, the screen displaying a canvas, the canvas being larger than the display area and containing an interactive element;

interface means for receiving input, wherein the computer transforms the received input into movement of the canvas relative to the display area; and

wherein the computer is operable for changing a status of the interactive element during movement of the canvas in response to proximity of the interactive element to a designated portion of the display area wherein changing the status of the interactive element comprises transitioning the interactive element from invisible, to translucent, to opaque as the canvas shifts and changing the interactive element from unselectable to selectable as the interactive element transitions from translucent to opaque.

26. The personal computer of claim 25, wherein the screen comprises a touchscreen.

27. The personal computer of claim 25 wherein the interactive element is visible but not selectable within a second portion of the display area.

28. The personal computer of claim 25 wherein the interactive element comprises an item selected from the list consisting of:

an icon;

a tile;

a window; and

a control feature.

29. The personal computer of claim 28 wherein the tile comprises:

a small collection of control features that work together.

30. The personal computer of claim 28 wherein the control feature comprises:

a single User Interface (UI) component.

31. The personal computer of claim 25 wherein the canvas comprises:

a virtual display area on which the interactive element is placed, and less than the entirety of the canvas is displayed on the screen at a given time.
