Abstract

Systems and methods according to the present invention provide a user interface for scrolling through lists of information on user interfaces.

Claims

1. A method for scrolling within a graphical user interface comprising:

displaying a first portion of a list having a first plurality of entries which are visible on said graphical user interface;

receiving user input to scroll said list by a number of entries;

displaying an animation of dummy data in portions of said graphical user interface associated with said first plurality of entries while said list is being scrolled, wherein said animation of dummy data is created for said list based on a set of representative content;

ceasing scrolling; and

replacing said animation of dummy data with a second portion of said list including a second plurality of entries.

2. The method of claim 1, wherein said step of displaying an animation of dummy data is provided if said user input requests scrolling of said list by more than a predetermined number of entries and wherein, if said user input requests scrolling of said list by fewer than said predetermined number, then said step of animating is omitted and actual data is displayed as said list is scrolled.

3. The method of claim 2, wherein said predetermined number of entries is greater than one page of entries when in a single-row scroll mode or a second spin of a scroll wheel when in a page-at-a-time scroll mode.

4. The method of claim 2, wherein when said step of animating is omitted, said actual data is displayed one row at a time from pre-filled off-screen rows when in single-row mode or said actual data is displayed one page at a time from a pre-filled off-screen page when in page-at-a-time mode.

5. The method of claim 1, wherein said animation of dummy data has an associated color palette, wherein said color palette relates to items in said scroll list.

6. The method of claim 1, further comprising:

displaying dynamic visual context information that is updated indicating current position within said list.

7. The method of claim 1, further comprising:

displaying dynamic visual context information that is updated indicating current destination within said list.

8. The method of claim 1, wherein said user input to scroll said list occurs by clicking top or bottom arrows on an on-screen toolbar to move said list up or down one row.

9. A non-transitory computer-readable medium containing program instructions coded thereon which, when executed by a computer or processor, perform the steps of:

displaying a first portion of a list having a first plurality of entries which are visible on said graphical user interface;

receiving user input to scroll said list by a number of entries;

displaying an animation of dummy data in portions of said graphical user interface associated with said first plurality of entries while said list is being scrolled, wherein said animation of dummy data is created for said list based on a set of representative content;

ceasing scrolling; and

replacing said animation of dummy data with a second portion of said list including a second plurality of entries.

10. The non-transitory computer-readable medium of claim 9, wherein said step of displaying an animation of dummy data is provided if said user input requests scrolling of said list by more than a predetermined number of entries and wherein, if said user input requests scrolling of said list by fewer than said predetermined number, then said step of animating is omitted and actual data is displayed as said list is scrolled.

11. The non-transitory computer-readable medium of claim 10, wherein said predetermined number of entries is greater than one page of entries when in a single-row scroll mode or a second spin of a scroll wheel when in a page-at-a-time scroll mode.

12. The non-transitory computer-readable medium of claim 10, wherein when said step of animating is omitted, said actual data is displayed one row at a time from pre-filled off-screen rows when in single-row mode or said actual data is displayed one page at a time from a pre-filled off-screen page when in page-at-a-time mode.

13. The non-transitory computer-readable medium of claim 9, further comprising:

displaying dynamic visual context information that is updated indicating current position within said list.

14. The non-transitory computer-readable medium of claim 9, further comprising:

displaying dynamic visual context information that is updated indicating current destination within said list.

15. A user interface generated by one or more processors executing sequences of instructions contained in a memory device, the user interface comprising:

a first portion of a list of items currently displayed on said user interface; and

a mechanism for receiving a user input to scroll said list,

wherein said user interface displays an animation of dummy data while said list is being scrolled and subsequently replaces said animation of dummy data with a second portion of said list, further wherein said animation of dummy data is created for said list based on a set of representative content.

16. The user interface of claim 15, wherein said display of said animation of dummy data is provided if said user input requests scrolling of said list by more than a predetermined number of entries and wherein, if said user input requests scrolling of said list by fewer than said predetermined number, then said animation of dummy data is omitted and actual data is displayed as said list is scrolled.

17. The user interface of claim 16, wherein when said animation of dummy data is omitted, said actual data is displayed one row at a time from pre-filled off-screen rows when in single-row mode or said actual data is displayed one page at a time from a pre-filled off-screen page when in page-at-a-time mode.

18. The user interface of claim 15, wherein said animation of dummy data has an associated color palette, wherein said color palette relates to items in said scroll list.

19. The user interface of claim 15, further comprising:

displaying dynamic visual context information that is updated indicating current position within said list.

20. The user interface of claim 15, further comprising:

displaying dynamic visual context information that is updated indicating current destination within said list.
