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 displaying at least one first interactive element on a display area of a touch screen;

code for receiving a sliding gesture on the touch screen; and

code for displaying at least one second interactive element on the display area of the touch screen, wherein;

when the at least one first interactive element is displayed, the at least one second interactive element is invisible,

when the at least one second interactive element is displayed, the at least one first interactive element is invisible, and

in a case that the at least one second interactive element transitions from invisible to being displayed, the at least one second interactive element transitions from invisible, to translucent, to opaque, and the at least one second interactive element changes from unselectable to selectable as the at least one second interactive element transitions from translucent to opaque.

2. The computer program product of claim 1 wherein the transition of the at least one second interactive element from invisible, to translucent, to opaque, comprises a gradual change in appearance of the at least one second interactive element.

3. The computer program product of claim 2 wherein the gradual change is applied as the at least one second interactive element approaches a center of the display area during navigation.

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

displaying at least one first interactive element on a display area of the touch screen;

receiving a sliding gesture on the touch screen; and

displaying at least one second interactive element on the display area of the touch screen, wherein;

when the at least one first interactive element is displayed, the at least one second interactive element is invisible,

when the at least one second interactive element is displayed, the at least one first interactive element is invisible, and

in a case that the at least one second interactive element transitions from invisible to being displayed, the at least one second interactive element transitions from invisible, to translucent, to opaque, and the at least one second interactive element changes from unselectable to selectable as the at least one second interactive element transitions from translucent to opaque.

5. The method of claim 4 wherein the transition of the at least one second interactive element from invisible, to translucent, to opaque, comprises a gradual change in appearance of the at least one second interactive element.

6. The method of claim 5 wherein the gradual change is applied as the at least one second interactive element approaches a center of the display area during navigation.

7. A handheld, processor-based device comprising:

a touch screen having a display area; and

a processor configured to;

control the touch screen to display at least one first interactive element on the display area;

receive a sliding gesture on the touch screen; and

display at least one second interactive element on the display area of the touch screen, wherein;

when the at least one first interactive element is displayed, the at least one second interactive element is invisible,

when the at least one second interactive element is displayed, the at least one first interactive element is invisible, and

in a case that the at least one second interactive element transitions from invisible to being displayed, the at least one second interactive element transitions from invisible, to translucent, to opaque, and the at least one second interactive element changes from unselectable to selectable as the at least one second interactive element transitions from translucent to opaque.

8. The handheld, processor-based device of claim 7 wherein the transition of the at least one second interactive element from invisible, to translucent, to opaque, comprises a gradual change in appearance of the at least one second interactive element.

9. The handheld, processor-based device of claim 8, wherein the gradual change is applied as the at least one second interactive element approaches a center of the display area during navigation.
