Abstract

Some embodiments provide a novel auto-scanning method for navigating elements within a user interface (UI) of a computing device. This method associates the UI elements into several overlapping groups, with each group having more than one element and having at least one element in common with at least one other group. The method successively identifies a different group of elements as a selectable group for a different duration of time. While a group is selectable, a user can select the group through an input device or mechanism. If a user does not select a first group of elements that is selectable during a first time period, the method identifies a second group of elements as being selectable during a second time period. While identifying the second group as selectable during the second time period, the method identifies the first as not being selectable during this time period. When a user selects a group of elements while the group is identified as being selectable, the method successively identifies as selectable different elements within the selected group. Upon receiving selection of a particular element within the selected group, the method performs an action associated with the particular element.

Claims

1. For a device that has a user interface that comprises a plurality of elements, a method comprising:

successively identifying as selectable a different group of elements from a plurality of overlapping groups of elements, wherein each identified group includes more than one element and includes at least one element in common with at least one other group;

receiving a selection of a particular group of elements while the particular group is identified as selectable;

successively identifying as selectable different elements within the selected group; and

upon receiving the selection of a particular element within the selected group, performing an action associated with the particular element.

2. The method of claim 1, wherein successively identifying a different group comprises visually identifying at different times different groups of elements as being selectable.

3. The method of claim 2, wherein visually identifying different selectable groups comprises:

visually identifying a first group as being selectable for a first duration of time; and

when the first group is not selected during the first duration of time, visually identifying a second group as being selectable for a second duration of time, while visually identifying the first group as not being selectable during the second duration of time.

4. The method of claim 1, wherein the elements are items in a menu.

5. The method of claim 1, wherein the elements are icons.

6. The method of claim 1, wherein the elements are alphanumeric characters.

7. The method of claim 6 further comprising:

displaying an arrangement of the alphanumeric characters;

wherein performing an action for the selected particular alphanumeric character comprises including the particular character in an input character string.

8. The method of claim 6, wherein successively identifying a different group comprises successively displaying a visual indicator for each group to signify that the group is selectable.

9. The method of claim 8, wherein displaying the visual indicator for a group comprises changing the appearance of the characters within the group.

10. The method of claim 8, wherein displaying the visual indicator for a group comprises highlighting the group;

wherein receiving the selection comprises receiving selection of the particular group when the particular group is highlighted.

11. The method of claim 6 further comprising providing a control for specifying the number of characters in each selectable group.

12. The method of claim 11 further comprising providing another control for specifying the number of characters that overlap between successive groups.

13. The method of any of claims 1 further comprising providing a control for defining the arrangement of alphanumeric characters.

14. The method of any of claims 1, wherein successively identified groups overlap in order to increase temporal duration during which any particular element that is in at least two successively enabled groups is selectable through an initial selection of one of the groups that contains the particular character.

15. The method of any of claims 1, wherein the groups of elements are smaller sub-groups of a particular larger group of elements, wherein the particular larger group of elements is part of a set of overlapping, larger groups of elements, the method further comprising:

before successively identifying as selectable a different sub-group of elements within the particular larger group of elements,

successively identifying as selectable a different group of elements from the set of overlapping, larger groups of elements, wherein each identified larger group includes more than one sub-group and includes at least one sub-group in common with at least one other larger group; and

receiving a selection of the particular larger group of elements while the larger particular larger group is identified as selectable.

16. A non-transitory machine readable medium for storing a program comprising sets of instructions for:

successively identifying as selectable a different group of elements from a plurality of overlapping groups of elements, wherein each identified group includes more than one element and includes at least one element in common with at least one other group;

receiving a selection of a particular group of elements while the particular group is identified as selectable;

successively identifying as selectable different elements within the selected group; and

upon receiving the selection of a particular element within the selected group, performing an action associated with the particular element.

17. The machine readable medium of claim 16, wherein the set of instructions for successively identifying a different group comprises a set of instructions for visually identifying at different times different groups of elements as being selectable.

18. The machine readable medium of claim 17, wherein the set of instructions for visually identifying different selectable groups comprises sets of instructions for:

visually identifying a first group as being selectable for a first duration of time; and

when the first group is not selected during the first duration of time, visually identifying a second group as being selectable for a second duration of time, while visually identifying the first group as not being selectable during the second duration of time.

19. The machine readable medium of claim 16, wherein the elements are alphanumeric characters, the program further comprising sets of instructions for:

displaying an arrangement of the alphanumeric characters;

wherein performing an action for the selected particular alphanumeric character comprises including the particular character in an input character string.

20. The machine readable medium of claim 19, wherein the set of instructions for successively identifying a different group comprises a set of instructions for successively displaying a visual indicator for each group to signify that the group is selectable.

21. The machine readable medium of claim 20, wherein the set of instructions for displaying the visual indicator for a group comprises a set of instructions for changing the appearance of the characters within the group.

22. The machine readable medium of claim 20,

wherein the set of instructions for displaying the visual indicator for a group comprises a set of instructions for highlighting the group;

wherein the set of instructions for receiving the selection comprises a set of instructions for receiving selection of the particular group when the particular group is highlighted.
