Abstract

A method of modifying attributes of list elements in a layout space of the list as the list scrolls in a user interface is disclosed herein. The method comprises determining a series of location values of each list element for a duration of a scroll event. Additionally, for each list element, at each determined location value of that list element, the attributes of that list element are determined by evaluating a set of spline curves associated with that list element based on that location value. The list elements are re-rendered in accordance with the determined attributes for the duration of the scroll event.

Claims

1. A method of modifying attributes of list elements in a layout space of the list as the list scrolls in a user interface, the method comprising:

for a duration of a scroll event, determining a series of location values of each list element;

for each list element, at each determined location value of that list element, determining the attributes of that list element by evaluating a set of spline curves associated with that list element based on that location value; and

re-rendering the list elements in accordance with the determined attributes for the duration of the scroll event.

2. The method of claim 1, wherein the attribute comprises a decoding attribute.

3. The method of claim 2, wherein the decoding attribute comprises an image decoding priority.

4. The method of claim 1, wherein the attribute comprises a response attribute.

5. The method of claim 4, wherein the response attribute comprises a double tap speed.

6. The method of claim 1, wherein the attribute comprises a rendered attribute.

7. The method of claim 6, wherein the rendered attribute comprises at least one of an opacity, a color, a depth, an orientation, and a shape.

8. The method of claim 6, wherein the rendered attribute comprises a coordinate in the user interface.

9. The method of claim 1, wherein the list is a linear list.

10. The method of claim 1, wherein the list is a circular list.

11. The method of claim 1, wherein the set of spline curves comprises functions that map the list element'"'"'s location value with one or more attributes.

12. The method of claim 1, wherein the determining the attributes of said list element is only done when the location value corresponds to an on-screen position.

13. An electronic device comprising:

one or more processors; and

,

memory comprising instructions which, when executed by one or more of the processors, cause the device to;

for a duration of a scroll event, determine a series of location values of each list element;

for each list element, at each determined location value of that list element, determine the attributes of that list element by evaluating a set of spline curves associated with that list element based on that location value; and

re-render the list elements in accordance with the determined attributes for the duration of the scroll event.

14. The electronic device of claim 13, wherein the attribute comprises a decoding attribute.

15. The electronic device of claim 14, wherein the decoding attribute comprises an image decoding priority.

16. The electronic device of claim 13, wherein the attribute comprises a response attribute.

17. The electronic device of claim 16, wherein the response attribute comprises a double tap speed.

18. The electronic device of claim 13, wherein the attribute comprises a rendered attribute.

19. The electronic device of claim 18, wherein the rendered attribute comprises at least one of an opacity, a color, a depth, an orientation, and a shape.

20. The electronic device of claim 18, wherein the rendered attribute comprises a coordinate in the user interface.

21. The electronic device of claim 13, wherein the list is a linear list.

22. The electronic device of claim 13, wherein the list is a circular list.

23. The electronic device of claim 13, wherein the set of spline curves are functions that map the list element'"'"'s location value with one or more attributes.

24. The electronic device of claim 13, wherein the determining the attributes of said list element is only done when the location value corresponds to an on-screen position.

25. A computer program product on an electronic device, the computer program product comprising memory comprising instructions which, when executed by one or more processors of the electronic device, cause the electronic device to:

for a duration of a scroll event, determine a series of location values of each list element;

for each list element, at each determined location value of that list element, determine the attributes of that list element by evaluating a set of spline curves associated with that list element based on that location value; and

re-render the list elements in accordance with the determined attributes for the duration of the scroll event.
