Abstract

In one example, a method includes outputting, for display at a presence-sensitive display, a graphical user interface including a text display region and a graphical keyboard. The method further includes receiving an indication of a first gesture detected at a location within the text display region, and selecting, based at least in part on the location within the text display region, at least a portion of a character string included in the text display region. The method further includes receiving, while the first gesture is detected at the presence-sensitive display, an indication of at least a portion of a second gesture to select at least one key of the graphical keyboard, and outputting, responsive to receiving an indication of a termination of at least the second gesture, a replacement character string for display within the text display region to replace the portion of the character string.

Claims

1. A method comprising:

outputting, by a computing device and for display, a graphical user interface including a text display region and a graphical keyboard comprising a plurality of character keys, wherein a visual indicator is positioned at a first location of the text display region;

responsive to receiving a first gesture detected at a second location of the text display region, repositioning, by the computing device, the visual indicator to the second location of the text display region;

selecting, by the computing device and based at least in part on the first gesture, at least a portion of a character string displayed within the text display region;

responsive to receiving a second gesture to select at least one character key from the plurality of character keys, outputting, by the computing device, for display within the text display region, a replacement character string that replaces at least the portion of the character string, the replacement character string being based at least in part on the at least one character key; and

responsive to outputting the replacement string and without receiving a third gesture to reposition the visual indicator, automatically repositioning, by the computing device, the visual indicator to the first location.

2. The method of claim 1, wherein the visual indicator comprises at least one of a cursor and a carat.

3. The method of claim 1, wherein the first location corresponds to a location at an end of the character string.

4. The method of claim 1, wherein automatically repositioning the visual indicator to the first location is further responsive to receiving, by the computing device, an indication of a termination of the second gesture.

5. The method of claim 1, wherein outputting the replacement character string for display within the text display region is further responsive to receiving, by the computing device, an indication of a termination of the second gesture.

6. The method of claim 1, wherein the portion of the character string comprises one or more characters bounded by one or more of a space delimiter character and a punctuation character.

7. The method of claim 1, wherein the at least one character key is a first character key, the method further comprising:

receiving, by the computing device, a fourth gesture to select at least a second character key from the plurality of character keys,

wherein outputting the replacement character string to replace at least the portion of the character string is further responsive to receiving, by the computing device, an indication of a termination of at least the fourth gesture.

8. The method of claim 7, wherein receiving the fourth gesture to select the second character key from the plurality of character keys comprises receiving the fourth gesture while the first gesture is detected at an input device.

9. The method of claim 7, wherein the second character key from the plurality of character keys comprises a character key from the plurality of character keys associated with a space delimiter character.

10. The method of claim 7, wherein the second character key from the plurality of character keys comprises a character key from the plurality of character keys associated with a punctuation character.

11. The method of claim 1, further comprising:

determining, by the computing device and based at least in part on the at least one character key, one or more candidate words;

outputting, by the computing device and for display, the one or more candidate words in the graphical user interface; and

receiving, by the computing device, a fourth gesture detected at an input device, the fourth gesture to select one of the one or more candidate words as a selected candidate word,

wherein outputting the replacement character string to replace at least the portion of the character string comprises outputting the selected candidate word to replace at least the portion of the character string.

12. A computer-readable storage medium encoded with instructions that, when executed, cause at least one processor to:

output for display, a graphical user interface including a text display region and a graphical keyboard comprising a plurality of character keys, wherein a visual indicator is positioned at a first location of the text display region;

responsive to receiving a first gesture detected at a second location of the text display region, reposition the visual indicator to the second location of the text display region;

select, based at least in part on the first gesture detected at the second location of the text display region, at least a portion of a character string included in the text display region;

responsive to receiving a second gesture to select at least one character key from the plurality of character keys, output, for display within the text display region a replacement character string that replaces at least the portion of the character string, the replacement character string being based at least in part on the at least one character key; and

responsive to outputting the replacement string and without receiving a third gesture to reposition the visual indicator, automatically reposition the visual indicator to the first location.

13. The computer-readable storage medium of claim 12, wherein the visual indicator comprises at least one of a cursor and a carat.

14. The computer-readable storage medium of claim 12, wherein automatically repositioning the visual indicator to the first location is further responsive to receiving an indication of a termination of the second gesture.

15. The computer-readable storage medium of claim 12, wherein outputting the replacement character string for display within the text display region is further responsive to receiving of a termination of the second gesture.

16. A device comprising:

at least one processor; and

at least one module operable by the at least one processor to;

output for display, a graphical user interface including a text display region and a graphical keyboard comprising a plurality of character keys, wherein a visual indicator is positioned at a first location of the text display region;

responsive to receiving a first gesture detected at a second location of the text display region, reposition the visual indicator to the second location of the text display region;

select, based at least in part on the first gesture detected at the second location of the text display region, at least a portion of a character string displayed within the text display region;

responsive to receiving a second gesture to select at least one character key from the plurality of character keys output, for display within the text display region, a replacement character string that replaces at least the portion of the character string, the replacement character string being based at least in part on the at least one character key; and

responsive to outputting the replacement string for display and without receiving a third gesture to reposition the visual indicator, automatically reposition the visual indicator to another location of the text display region.

17. The device of claim 16, wherein the visual indicator comprises at least one of a cursor and a carat.

18. The device of claim 16, wherein automatically repositioning the visual indicator to another location is further responsive to receiving an indication of a termination of the second gesture.

19. The device of claim 16, wherein outputting the replacement character string for display within the text display region is further responsive to receiving an indication of a termination of the second gesture.

20. The device of claim 16, wherein the at least one character key is a first character key, wherein the at least one module is operable by the at least one processor to:

receive a fourth gesture to select at least a second character key from the plurality of character keys,

wherein outputting the replacement character string to replace at least the portion of the character string is further responsive to receiving an indication of a termination of at least the fourth gesture.
