Abstract

Embodiments provide exemplary methods and systems for implementing an elastic over-scroll. An exemplary method includes displaying, on a display device, a list of items including a first item located at a first position and a second item located at a second position. The exemplary method also includes identifying an end of the list at the first position, and detecting an object associated with a movement in a first direction toward the first item. The method further includes increasing a distance between the first item and the second item while maintaining the display of the first item at the first position, based on the detecting.

Claims

1-23. -23. (canceled)

24. A computer-implemented method, comprising:

displaying, on a display device, a list of items including a first item located at a first position and a second item located at a second position;

detecting a speed of an object associated with a movement in a first direction toward the first item; and

moving the second item a distance from the second position to a third position on the display while maintaining the display of the first item at the first position, wherein the distance is based at least on the detected speed.

25. The method of claim 24, wherein the list of items comprises at least one of a block of text, lines of text, or images.

26. The method of claim 24, further comprising:

identifying a maximum distance between the first and second items;

detecting the object on the display device; and

when a distance between the first and second items is less than the maximum distance, moving the second item at the third position a farther distance from the first item based on the object detecting.

27. The method of claim 24, further comprising:

determining that the object is not detected on the display device;

when it is determined that the object is not detected on the display device, moving the second item to the second position on the display; and

after moving the second item, displaying the first item at the first position and the second item at the second position.

28. The method of claim 27, wherein the moving moves the second item at a speed based at least on the detected speed.

29. The method of claim 27, wherein the moving moves the second item at a speed based at least on a density of underlying data in the list.

30. The method of claim 24, wherein the distance is based at least on a number of items in the list, and the moving the second item moves the second item the distance based at least on the number of items in the list.

31. The method of claim 24, wherein the first position is located at a beginning or end of the list.

32. A system, comprising:

a display configured to display a list of items including a first item located at a first position and a second item located at a second position; and

an input device configured to detect a speed of an object associated with a movement in a first direction toward the first item; and

wherein the display is further configured to display the second item moved a distance from the second position to a third position while maintaining the display of the first item at the first position, wherein the distance is based at least on the detected speed.

33. The system of claim 32, wherein the list of items comprises at least one of a block of text, lines of text, or images.

35. The system of claim 32, wherein when the input device determines that the object is not detected on the display device, the display device is configured to display the first item and the second item at a decreased distance and to display the first item at the first position and the second item at the second position.

36. The system of claim 32, wherein the first distance is based at least on a number of items in the list.

37. The system of claim 32, wherein the first position is located at a beginning or end of the list.

38. The system of claim 32, wherein the object associated with the movement is a finger or a pointing device.

34. The system of 32, wherein the display is configured to display the first item and the second item at a proportionally increased distance based on the detected speed of the object and a number of items in the list.

39. A computer storage medium encoded with a computer program, the program comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

displaying, on a display device, a list of items including a first item located at a first position and a second item located at a second position;

detecting a speed of an object associated with a movement in a first direction toward the first item; and

moving the second item a distance from the second position to a third position on the display while maintaining the display of the first item at the first position, wherein the distance is based at least on the detected speed.

40. The computer storage medium of claim 39, wherein the list of items comprises at least one of a block of text, lines of text, or images.

41. The computer storage medium of claim 39, further comprising:

determining that the object is not detected on the display device;

when it is determined that the object is not detected on the display device, moving the second item to the second position on the display; and

after moving the second item, displaying the first item at the first position and the second item at the second position.

42. The computer storage medium of claim 39, wherein the moving moves the second item at a speed based at least on the detected speed, a density of the underlying data in the list, and a number of items in the list.

43. The computer storage medium of claim 39, wherein the first position is located at a beginning or end of the list.
