Abstract

In general, this disclosure describes techniques to enable a user of a computing device to select keys representing one or more characters using touch gestures. In one example, a method includes: receiving, on a graphical keyboard of a computing device, touch input including a plurality of selections of one or more keyboard characters currently displayed in the graphical keyboard; determining, by the computing device, a touch input operation that corresponds to the touch input, wherein the touch input operation identifies a character that is not currently displayed on the graphical keyboard, wherein the identified character has a phonetic relationship to the one or more keyboard characters selected by the touch input, and wherein the identified character is different from the one or more keyboard characters selected by the touch input; and generating for display, on an output device of the computing device, the identified character.

Claims

1. A method comprising:

receiving, on a graphical keyboard of a computing device, touch input comprising a plurality of selections of one or more keyboard characters currently displayed on the graphical keyboard;

determining, by the computing device, a touch input operation that corresponds to the touch input, wherein the touch input operation identifies a character that is not currently displayed on the graphical keyboard, wherein the identified character has a phonetic relationship to the one or more keyboard characters selected by the touch input, and wherein the identified character is different from the one or more keyboard characters selected by the touch input; and

generating for display, on an output device of the computing device, the identified character.

2. The method of claim 1, further comprising:

receiving, on the graphical keyboard, the touch input comprising a single selection of one keyboard character currently displayed on the graphical keyboard; and

selecting, by the computing device for purposes of display, the one keyboard character currently displayed in the graphical keyboard.

3. The method of claim 1, wherein determining, by the computing device, the touch input operation that corresponds to the touch input comprises determining, by the computing device, a lookup of the identified character in a table based on the touch input operation, wherein the table comprises mappings between one or more characters and one or more touch input operations.

4. The method of claim 3, further comprising:

storing the table in a database on the computing device.

5. The method of claim 1, wherein receiving, on the graphical keyboard of the computing device, the touch input comprises determining, by the computing device, a duration of at least one of the selections of the touch input.

6. The method of claim 5, wherein determining, by the computing device, the duration of the at least one of the selections of the touch input further comprises selecting the input operation based on the duration of the at least one of the selections of the touch input.

7. The method of claim 1, wherein the identified character is not represented in the graphical keyboard.

8. The method of claim 1, wherein the phonetic relationship comprises a relationship between a vowel and a diphthong.

9. The method of claim 1, wherein the phonetic relationship comprises a relationship between a single vowel and a double vowel.

10. The method of claim 1, wherein the phonetic relationship comprises a relationship between a simple consonant and an aspirated derivative of the simple consonant.

11. The method of claim 1, wherein the phonetic relationship comprises a relationship between a simple consonant and a faucalized consonant.

12. The method of claim 1, wherein the phonetic relationship comprises a relationship between a simple consonant and a consonant cluster.

13. The method of claim 1, wherein the phonetic relationship comprises a relationship between a first double vowel and a second double vowel.

14. The method of claim 1, wherein the graphical keyboard is displayed by a touch-sensitive screen of the computing device.

15. The method of claim 1, wherein the touch input comprises a swipe, pinch, de-pinch, tap, rotate, double tap, long press, or combo press.

16. The method of claim 1, wherein each of the one or more keyboard characters are selected for representation on the graphical keyboard based on a frequency, wherein the frequency comprises a number of occurrences that a keyboard character of the graphical keyboard is selected by a user.

17. The method of claim 16, wherein the one or more keyboard characters of the graphical keyboard comprise a frequently selected group of characters that are more frequently selected by a user than a less frequently selected group of characters.

18. The method of claim 1, wherein the one or more keyboard characters of the graphical keyboard are not phonetically related.

19. A computer-readable storage medium encoded with instructions that cause one or more processors of a computing device to:

receive, on a graphical keyboard of a computing device, touch input comprising a plurality of selections of one or more keyboard characters currently displayed on the graphical keyboard;

determine, by the computing device, a touch input operation that corresponds to the touch input, wherein the touch input operation identifies a character that is not currently displayed on the graphical keyboard, wherein the identified character has a phonetic relationship to the one or more keyboard characters selected by the touch input, and wherein the identified character is different from the one or more keyboard characters selected by the touch input; and

generate for display, on an output device of the computing device, the identified character.

20. A computing device, comprising:

one or more processors;

an output device;

a keyboard application implemented by the one or more processors to receive a touch input comprising a plurality of selections of one or more keyboard characters of a graphical keyboard currently displayed on the output device; and

means for determining a touch input operation that corresponds to the touch input, wherein the touch input operation identifies a character that is not currently displayed on the graphical keyboard, wherein the identified character has a phonetic relationship to the one or more keyboard characters selected by the touch input, and wherein the identified character is different from the one or more keyboard characters selected by the touch input,

wherein the output device is configured to generate for display the identified character.
