Abstract

A method for word correction on a multi-touch device, including: detecting a selection by a user of a word displayed in a user interface of the multi-touch device; breaking the word into logical segments; presenting the logical segments in the user interface; detecting a user-selected segment of one of the logical segments; displaying at least one alternative segment for the user-selected segment in the user interface; and altering the selected segment in response to receiving a user-selected replacement from the at least one alternative segment.

Claims

1. A computer program product, comprising:

a non-transitory computer readable storage medium to store a computer readable program, wherein the computer readable program, when executed by a processor within a computer, causes the computer to perform operations for word correction in a multi-touch device, the operations comprising;

detecting a selection by a user of a word displayed in a user interface of the multi-touch device;

breaking the word into logical segments, wherein at least one of the logical segments comprises a plurality of characters;

presenting the logical segments in the user interface;

detecting a user-selected segment of one of the logical segments;

displaying at least one alternative segment for the user-selected segment in the user interface; and

altering the selected segment in response to receiving a user-selected replacement from the at least one alternative segment.

2. The computer program product of claim 1, wherein the alternative segment comprises a common alternative usage of letters similar to the user-selected segment.

3. The computer program product of claim 1, wherein the computer readable program, when executed on the computer, causes the computer to perform additional operations, comprising:

determining a plurality of alternative segments for the user-selected segment, wherein each alternative segment comprises at least one letter difference than the user-selected segment; and

displaying the plurality of alternative segments in the user interface.

4. The computer program product of claim 3, wherein the computer readable program, when executed on the computer, causes the computer to perform additional operations, comprising:

altering the selected segment in response to receiving a manual user replacement, wherein the at least one alternative segment is determined to be an incorrect replacement for the user-selected segment.

5. The computer program product of claim 1, wherein breaking the word into logical segments further comprises separating the word into syllables.

6. The computer program product of claim 1, wherein breaking the word into logical segments further comprises separating the word into compound word segments.

7. The computer program product of claim 1, wherein the computer readable program, when executed on the computer, causes the computer to perform additional operations, comprising:

breaking at least one logical segment comprising a plurality of characters into smaller logical segments in response to a user input to the multi-touch device, wherein the user input comprises maintained contact on the word on the multi-touch device for an amount of time that exceeds a predetermined time threshold.

8. A method for word correction on a multi-touch device, comprising:

detecting a selection by a user of a word displayed in a user interface of the multi-touch device;

breaking the word into logical segments, wherein at least one of the logical segments comprises a plurality of characters;

presenting the logical segments in the user interface;

detecting a user-selected segment of one of the logical segments;

displaying at least one alternative segment for the user-selected segment in the user interface; and

altering the selected segment in response to receiving a user-selected replacement from the at least one alternative segment.

9. The method of claim 8, wherein the alternative segment comprises a common alternative usage of letters similar to the user-selected segment.

10. The method of claim 8, further comprising:

determining a plurality of alternative segments for the user-selected segment, wherein each alternative segment comprises at least one letter difference than the user-selected segment; and

displaying the plurality of alternative segments in the user interface.

11. The method of claim 10, further comprising:

altering the selected segment in response to receiving a manual user replacement, wherein the at least one alternative segment is determined to be an incorrect replacement for the user-selected segment.

12. The method of claim 8, wherein breaking the word into logical segments further comprises separating the word into syllables.

13. The method of claim 8, wherein breaking the word into logical segments further comprises separating the word into compound word segments.

14. The method of claim 8, further comprising:

breaking at least one logical segment comprising a plurality of characters into smaller logical segments in response to a user input to the multi-touch device, wherein the user input comprises maintained contact on the word on the multi-touch device for an amount of time that exceeds a predetermined time threshold.

15. A word correction system, comprising:

a multi-touch device comprising a user interface, wherein the multi-touch device is configured to receive touch input from a user to interact with the user interface; and

a word correction engine, configured to;

detect a selection by the user of a word displayed in the user interface;

break the word into logical segments, wherein at least one of the logical segments comprises a plurality of characters;

present the logical segments in the user interface;

detect a user-selected segment of one of the logical segments;

display at least one alternative segment for the user-selected segment in the user interface; and

alter the selected segment in response to receiving a user-selected replacement from the at least one alternative segment.

16. The system of claim 15, wherein the alternative segment comprises a common alternative usage of letters similar to the user-selected segment.

17. The system of claim 15, wherein the word correction engine is further configured to:

determine a plurality of alternative segments for the user-selected segment, wherein each alternative segment comprises at least one letter difference than the user-selected segment; and

display the plurality of alternative segments in the user interface.

18. The system of claim 15, wherein breaking the word into logical segments further comprises separating the word into syllables.

19. The system of claim 15, wherein breaking the word into logical segments further comprises separating the word into compound word segments.

20. The system of claim 15, wherein the word correction engine is further configured to:

break at least one logical segment comprising a plurality of characters into smaller logical segments in response to a user input to the multi-touch device, wherein the user input comprises maintained contact on the word on the multi-touch device for an amount of time that exceeds a predetermined time threshold.
