Abstract

A computing device includes at least one processor and at least one module. The module may determine and output for display a list of one or more suggested character strings based on a first input received at a presence-sensitive display. The module may further receive an indication of a second user input detected at the presence-sensitive display. The module may further determine whether the second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a substantially leftward direction and a second gesture in a substantially rightward direction. Responsive to determining that the received gesture input includes the replacement gesture, the module may output for display in place of the displayed text, a character string chosen from the list of one or more suggested character strings.

Claims

1. A method comprising:

receiving, by a computing device, an indication of a first user input detected at a presence-sensitive display;

outputting, by the computing device and for display in a text display area at the presence-sensitive display, text based on the first user input detected at the presence-sensitive display;

determining, by the computing device, a list of one or more suggested character strings based on the text;

outputting, by the computing device and for display at the presence-sensitive display, the list of one or more suggested character strings;

receiving, by the computing device, an indication of a second user input detected at the presence-sensitive display;

determining whether the received second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a substantially leftward direction and a second gesture in a substantially rightward direction; and

responsive to determining that the received gesture input includes the replacement gesture, outputting, by the computing device and for display at the presence-sensitive display in place of the text in the text display area, a character string from the list of one or more suggested character strings, wherein the character string is ranked higher than at least one other character string from the list of one or more suggested character strings that are ranked in a ranked order.

2. The method of claim 1, wherein the chosen character string is a first character string in the list of suggested character strings.

3. The method of claim 1, wherein the first input indicates a plurality of characters entered by a user at the presence-sensitive display.

4. The method of claim 1, wherein the second gesture in the substantially rightward direction is received subsequent to the first gesture in the substantially leftward direction.

5. The method of claim 1, further comprising comparing the received second input with replacement gesture data to identify whether the received second input includes the replacement gesture.

6. The method of claim 5, further comprising ranking, by the computing device, the list of one or more suggested character strings such that a highest ranked character string in the list of one or more suggested character strings is a most probable match to the plurality of characters entered at the presence-sensitive display.

7. The method of claim 1, wherein the list of one or more suggested character strings are displayed in a ranked order.

8. The method of claim 1, wherein the character string is a highest ranked character string from the list of one or more suggested character strings that are ranked in the ranked order.

9. The method of claim 1, wherein the replacement gesture is entered by a user at the presence-sensitive display.

10. The method of claim 1, wherein the list of one or more suggested character strings are displayed in a ranked order.

11. A device comprising:

at least one processor; and

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

receive an indication of a first user input detected at a presence-sensitive display;

output, for display in a text display area at the presence-sensitive display, text based on the first user input detected at the presence-sensitive display;

determine a list of one or more suggested character strings based on the text;

output, for display at the presence-sensitive display, the list of one or more suggested character strings;

receive an indication of a second user input detected at the presence-sensitive display;

determine whether the received second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a substantially leftward direction and a second gesture in a substantially rightward direction; and

responsive to determining that the received gesture input includes the replacement gesture, output, for display at the presence-sensitive display in place of the text in the text display area, a character string from the list of one or more suggested character strings, wherein the character string is ranked higher than at least one other character string from the list of one or more suggested character strings that are ranked in a ranked order.

12. The device of claim 11, wherein the plurality of characters includes text entered by a user at the presence-sensitive display.

13. The device of claim 11, wherein the replacement gesture is entered by a user at the presence-sensitive display.

14. The device of claim 11, wherein the gesture in the substantially rightward direction is received subsequent to the gesture in the substantially leftward direction.

15. The device of claim 11, wherein the character string is a highest ranked character string from the list of one or more suggested character strings that are ranked in the ranked order.

16. A computer-readable storage medium encoded with instructions that, when executed, cause at least one processor of a computing device to perform operations comprising:

receiving, by a computing device, an indication of a first user input detected at a presence-sensitive display;

outputting, by the computing device and for display in a text display area at the presence-sensitive display, text based on the first user input detected at the presence-sensitive display;

determining, by the computing device, a list of one or more suggested character strings based on the text;

outputting, by the computing device and for display at the presence-sensitive display, the list of one or more suggested character strings;

receiving, by the computing device, an indication of a second user input detected at the presence-sensitive display;

determining whether the received second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a substantially leftward direction and a second gesture in a substantially rightward direction; and

responsive to determining that the received gesture input includes the replacement gesture, outputting, by the computing device and for display at the presence-sensitive display in place of the text in the text display area, a character string from the list of one or more suggested character strings, wherein the character string is ranked higher than at least one other character string from the list of one or more suggested character strings that are ranked in a ranked order.

17. The computer-readable storage medium of claim 16, wherein the text input includes text entered by a user at the presence-sensitive display.

18. The computer-readable storage medium of claim 16, wherein the replacement gesture is executed by a user at the presence-sensitive display.

19. The computer-readable storage medium of claim 16, wherein the second gesture in the substantially rightward direction is received within a predetermined period of time from receipt of the first gesture in the substantially leftward direction.

20. The computer-readable storage medium of claim 16, wherein the character string is a highest ranked character string from the list of one or more suggested character strings that are ranked in the ranked order.
