Abstract

Systems and methods for navigating a document by scrolling are provided. A first portion of the document is displayed within a display area. A user action to scroll the document is determined. A second portion of the document is determined. A visual feedback of a transition between the first portion and the second portion along a coordinate plane and an axis of rotation is provided within the display area. The second portion of the document is displayed within the display area.

Claims

1. A method for navigating a document by scrolling, the method comprising:

displaying, by a mobile computing device, a first portion of the document within a display area of the mobile computing device;

determining a user action to scroll the document;

determining a second portion of the document;

providing a visual feedback within the display area of a transition between the first portion and the second portion along a coordinate plane and an axis of rotation; and

displaying the second portion of the document within the display area.

2. The method of claim 1, wherein determining the second portion comprises:

determining a starting point within the document of the first portion;

determining a number of display units of the document;

determining a number of delta units of the document; and

determining a range of consecutive units of the document using the starting point of the first portion, the number of display units, and the number of delta units; and

displaying the range of consecutive units.

3. The method of claim 2, wherein the number of delta units are determined by the display units.

4. The method of claim 2, wherein the number of delta units are determined by a percentage of the size of the document.

5. The method of claim 2, wherein the delta units of the document are not displayed within the display area during the transition between the first portion and the second portion.

6. The method of claim 1, further comprising determining a directional component of the user action, wherein the second portion of the document is based on the directional component.

7. The method of claim 1, wherein the visual feedback is an animation of the transition, wherein displaying the visual feedback comprises:

displaying at least a part of the second portion as a mirror image in a background position of the display area; and

displaying at least a part of the first portion in a foreground position of the display area.

8. The method of claim 7, further comprising:

transitioning at least a part of the second portion to the foreground position; and

transitioning at least a part of the first portion to the background position.

9. The method of claim 1, wherein displaying the visual feedback comprises:

displaying animation of an image of a three-dimensional object tilting on an “

X-Y”

axis, wherein at least a part of the first portion is represented on a foreground position on the object, and wherein at least a part of the second portion is represented on a background position on the object.

10. The method of claim 9, wherein displaying the visual feedback further comprises:

displaying animation of the image of the object spinning along the axis of rotation, wherein the axis of rotation is a “

Z”

axis.

11. The method of claim 10, wherein displaying the visual feedback further comprises:

displaying animation of the image of the object tilting on an “

X-Y”

axis, wherein at least a part of the first portion is represented on the background position on the object, and wherein at least a part of the second portion is represented on the foreground position on the object.

12. The method of claim 1, wherein determining a user action to scroll the document comprises detecting a tap-hold-drag user gesture in a diagonal direction of a touchscreen.

13. The method of claim 1, further comprising:

determining the transition between the first portion and the second portion crosses an end-to-end boundary of the document; and

outputting sensory feedback in response to determining the transition crosses the end-to-end boundary of the document.

15. The system of claim 13, wherein the display screen displays the visual feedback by displaying animation of an image of a three-dimensional object tilting on an “

X-Y”

axis, wherein at least a part of the first portion is represented on a foreground position on the object, and wherein at least a part of the second portion is represented on a background position on the object.

14. A system for navigating a document by scrolling, the system comprising:

a display screen, for displaying a first portion of the document within a display area;

an input device, for receiving a user action to perform incremental scrolling of the document;

wherein, responsive to the user action, the display screen displays a visual feedback of a transition between the first portion and a second portion of the document within the display area along a coordinate plane and an axis of rotation; and

wherein responsive to displaying the visual feedback, the display screen displays the second portion of the document within the display area.

16. The system of claim 14, wherein the display screen displays the visual feedback by displaying animation of the image of the object spinning along the axis of rotation, wherein the axis of rotation is a “

Z”

axis

17. The system of claim 14, wherein the user action comprises a tap-hold-drag gesture in a diagonal direction.

18. A non-transitory computer-readable medium storing a plurality of instructions to control a data processor, the plurality of instructions comprising instructions that cause the data processor to:

display a first portion of a document within a display area;

determine a user action to scroll the document;

determine a second portion of the document;

provide a visual feedback of a transition between the first portion and the second portion within the display area along a coordinate plane and an axis of rotation; and

display the second portion of the document within the display area.

19. The non-transitory computer-readable medium of claim 18, wherein the instructions that cause the data processor to display the visual feedback comprise instructions that cause the data processor to:

display at least a part of the second portion as a mirror image in a background position of the display area; and

display at least a part of the first portion in a foreground position of the display area.

20. The non-transitory computer-readable medium of claim 19, wherein the instructions that cause the data processor to display the visual feedback further comprise instructions that cause the data processor to:

transition at least a part of the second portion to the foreground position; and

transition at least a part of the first portion to the background position.
