Abstract

A communication device includes a display with a layout including key locations with associated characters. The communication device detects an input gesture and determines one or more committed characters based at least in part on a change in the input gesture. The device presents one or more strings on the layout in association with key locations that are selected based at least in part on a relationship between each presented string and non-committed characters of each presented string.

Claims

1. An input method for a communication device having a programmed algorithm configured to predict input, the input method comprising:

displaying an initial predicted string;

detecting a swipe input gesture;

determining one or more committed characters, wherein each one of the one or more committed characters is committed based at least in part on a change of direction in the swipe input gesture at a key location associated with the corresponding committed character, and;

displaying an updated predicted string, the updated predicted string including the one or more committed characters and having been generated by the programmed algorithm configured to predict input,

wherein the updated predicted string is presented at or near a key location associated with the non-committed characters of the updated predicted string.

2. The input method of claim 1, further comprising receiving a selection input reflecting a selection of the updated predicted string.

3. The input method of claim 2, wherein the selection input comprises one of:

a tap gesture or a flick in the direction of the updated predicted string.

4. The input method of claim 1, further comprising displaying a second updated predicted string at or near the key location.

5. The input method of claim 4, wherein the updated predicted string and the second updated predicted string are presented in a selection list.

6. The input method of claim 4, wherein the updated predicted string and the second updated predicted string are presented in a cluster at or near the key location.

7. The input method of claim 1, wherein the swipe input gesture includes pauses over one or more key locations and the updated predicted string includes a verbatim string of the associated characters of the one or more key locations.

8. The input method of claim 7, wherein the verbatim string is presented at or near a key location associated with a space character.

9. The input method of claim 1 wherein the updated predicted string is presented:

adjacent to the key location, above the key location, or in close proximity to the key location.

10. A communication device, comprising:

a display, and

a processor configured to read computer executable instructions that when executed;

display an initial predicted string;

detect a swipe gesture;

determine one or more committed characters, wherein each one of the one or more committed characters is committed based at least in part on a change of direction in the swipe gesture at a key location associated with the corresponding committed character, and;

display an updated predicted string at or near a key location that is selected based at least in part on a relationship between the updated predicted string and non-committed characters of the updated predicted string,

wherein the updated predicted string includes the one or more committed characters.

11. The communication device of claim 10, wherein the processor is further configured to read computer executable instructions that when executed receive a selection input reflecting a selection of the updated predicted string.

12. The communication device of claim 11 wherein the selection input comprises one of:

a tap gesture or a flick in the direction of the updated predicted string.

13. The communication device of claim 10, wherein the processor is further configured to read computer executable instructions that when executed display a second updated predicted string at or near the key location.

14. The communication device of claim 13, wherein the updated predicted string and the second updated predicted string are presented in a selection list.

15. The communication device of claim 13, wherein the updated predicted string and the second updated predicted string are presented in a cluster around the key location.

16. The communication device of claim 10, wherein the input gesture comprises pauses over one or more key locations and the updated predicted string is a verbatim string of the associated characters of the one or more key locations.

17. The communication device of claim 16 wherein the verbatim string is presented at a key location associated with a space character.

18. The communication device of claim 10, wherein the updated predicted string is displayed at or near a key locations by displaying the updated predicted string adjacent to the key location, above the key locations, or in close proximity to the key location.

19. An input method for a communication device having a keyboard, the input method comprising:

detecting an input gesture, the input gesture comprising a direction,

determining one or more committed characters, wherein each one of the one or more committed characters is committed based at least in part on a change of the direction of the input gesture at a key location associated with the corresponding committed character and,

presenting on a display one or more strings at or near key locations that are selected based at least in part on a relationship between each presented string and a character associated with the selected key location,

wherein the one or more strings include the one or more committed characters.

20. The input method of claim 19, wherein the one or more strings are presented by displaying the one or more strings:

adjacent to the key locations, above the key locations, or in close proximity to the key locations.
