Abstract

An apparatus for providing an adaptive keypad on touch display devices may include a processing element. The processing element may be configured to receive an indication of a detection of a touch event invoking an operation related to a text character entry, determine candidate text characters based on the operation, and provide for a display of an adaptive keypad having a size that is variable based on the candidate text characters.

Claims

1. A method comprising:

receiving an indication of a detection of a touch event invoking an operation related to a text character entry;

determining candidate text characters based on the operation; and

providing for a display of an adaptive keypad having a size that is variable based on the candidate text characters.

2. A method according to claim 1, wherein determining candidate text characters comprises, for each entry of a current text character, re-determining candidate text characters based on the currently entered text character and any previously entered text characters of the same query.

3. A method according to claim 2, further comprising updating a size of the adaptive keyboard based on the re-determination of the candidate text characters.

4. A method according to claim 1, wherein receiving the indication of the detection of the touch event invoking the operation comprises receiving an indication of an initiation of a search operation related to a list of content items.

5. A method according to claim 4, wherein receiving the indication of the initiation of the search operation further comprises receiving an input of a text character associated with defining a query.

6. A method according to claim 4, further comprising providing for a display of the list of content items at a first portion of a touch screen display, wherein providing for the display of the adaptive keypad comprises providing for the display of the adaptive keypad at a second portion of the touch screen display.

7. A method according to claim 6, further comprising increasing a size of the first portion and correspondingly decreasing a size of the second portion based on changes to a quantity of the candidate text characters.

8. A method according to claim 1, wherein providing for the display of the adaptive keypad comprises displaying a keypad including a plurality of text characters, of which less than all the text characters are included in the candidate text characters, and wherein a size of the keypad is determined based on a quantity of the candidate text characters as compared to a quantity of the plurality of text characters.

9. A method according to claim 8, wherein providing for the display of the adaptive keypad comprises shrinking the size of the keypad in proportion to a decrease in the quantity of candidate text characters.

10. A method according to claim 1, wherein providing for the display of the adaptive keypad comprises displaying a keypad including only the candidate text characters.

11. A computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion for receiving an indication of a detection of a touch event invoking an operation related to a text character entry;

a second executable portion for determining candidate text characters based on the operation; and

a third executable portion for providing for a display of an adaptive keypad having a size that is variable based on the candidate text characters.

12. A computer program product according to claim 11, wherein the second executable portion includes instructions for, for each entry of a current text character, re-determining candidate text characters based on the currently entered text character and any previously entered text characters of the same query.

13. A computer program product according to claim 12, further comprising a fourth executable portion for updating a size of the adaptive keyboard based on the re-determination of the candidate text characters.

14. A computer program product according to claim 11, wherein the first executable portion includes instructions for receiving an indication of an initiation of a search operation related to a list of content items.

15. A computer program product according to claim 11, wherein the third executable portion includes instructions for displaying a keypad including a plurality of text characters, of which less than all the text characters are included in the candidate text characters, and wherein a size of the keypad is determined based on a quantity of the candidate text characters as compared to a quantity of the plurality of text characters.

16. A computer program product according to claim 15, wherein the third executable portion includes instructions for shrinking the size of the keypad in proportion to a decrease in the quantity of candidate text characters.

17. A computer program product according to claim 11, wherein the third executable portion includes instructions for displaying a keypad including only the candidate text characters.

18. An apparatus comprising a processing element configured to:

receive an indication of a detection of a touch event invoking an operation related to a text character entry;

determine candidate text characters based on the operation; and

provide for a display of an adaptive keypad having a size that is variable based on the candidate text characters.

19. An apparatus according to claim 18, wherein the processing element is further configured to, for each entry of a current text character, re-determine candidate text characters based on the currently entered text character and any previously entered text characters of the same query.

20. An apparatus according to claim 19, wherein the processing element is further configured to update a size of the adaptive keyboard based on the re-determination of the candidate text characters.

21. An apparatus according to claim 18, wherein the processing element is further configured to display a keypad including a plurality of text characters, of which less than all the text characters are included in the candidate text characters, and wherein a size of the keypad is determined based on a quantity of the candidate text characters as compared to a quantity of the plurality of text characters.

22. An apparatus according to claim 21, wherein the processing element is further configured to shrink the size of the keypad in proportion to a decrease in the quantity of candidate text characters.

23. An apparatus according to claim 18, wherein the processing element is further configured to display a keypad including only the candidate text characters.

24. An apparatus comprising:

means for receiving an indication of a detection of a touch event invoking an operation related to a text character entry;

means for determining candidate text characters based on the operation; and

means for providing for a display of an adaptive keypad having a size that is variable based on the candidate text characters.

25. An apparatus according to claim 24, wherein means for determining candidate text characters comprises, for each entry of a current text character, means for re-determining candidate text characters based on the currently entered text character and any previously entered text characters of the same query.
