Abstract

A method that includes receiving an input string, ranking, by the processor, a predicted string associated with the input string, wherein the ranking depends on whether the input string is a substring of the predicted string and at least on one of a typing speed and a typing confidence, and displaying the ranked predicted string.

Claims

1. An input method for a communication device having a processor, the method comprising:

receiving an input character string;

ranking, by the processor, a predicted character string associated with the input character string, wherein the ranking depends on whether the input character string is a substring of the predicted character string and at least on one of a typing speed and a typing confidence, wherein the typing speed reflects a speed at which the character string is input, and wherein the typing confidence reflects a confidence in a detected input associated with the input character string; and

displaying the ranked predicted character string.

2. The method of claim 1, wherein the ranking is in direct relationship with the typing speed if the input character string is not a substring of the predicted character string.

3. The method of claim 1, wherein the ranking is in inverse relationship with the typing speed if the input character string is a substring of the predicted character string.

4. The method of claim 1, wherein the typing speed comprises the average typing speed across a predetermined number of most recently typed characters.

5. The method of claim 1, further comprising determining the typing confidence based at least on the strength of one or more touches associated with the input character string.

6. The method of claim 5, further comprising determining the strength of the touches based on the area of the location of the touch.

7. The method of claim 5, wherein the ranking is in direct relationship with the typing confidence if the input character string is a substring of the predicted character string.

8. The method of claim 5, wherein the ranking is in inverse relationship with the typing speed if the input character string is not a substring of the predicted character string.

9. The method of claim 5, wherein the typing speed comprises the average typing speed across a predetermined number of most recently typed characters.

10. The method of claim 1, wherein displaying the ranked predicted character string comprises displaying the ranked predicted character string responsive to a determination that the ranked predicted character string is among a predetermined number of most highly ranked predicted character strings.

11. An electronic device comprising a display and a processor, the processor configured to perform:

receiving an input character string;

ranking a predicted character string associated with the input character string, wherein the ranking depends on whether the input character string is a substring of the predicted character string and at least on one of a typing speed and a typing confidence, wherein the typing speed is based on a typing speed value determined with respect to a predetermined threshold value, and wherein the typing confidence is based on a typing confidence value that reflects the confidence with which the input character string is input; and

displaying the ranked predicted character string on the display.

12. The electronic device of claim 11, wherein the ranking is in direct relationship with the typing speed if the input character string is not a substring of the predicted character string.

13. The electronic device of claim 11, wherein the ranking is in inverse relationship with the typing speed if the input character string is a substring of the predicted character string.

14. The electronic device of claim 11, wherein the typing speed comprises the average typing speed across a predetermined number of most recently typed characters.

15. The electronic device of claim 11, wherein the processor is further configured to perform:

determining the typing confidence based on the strength of one or more touches associated with the input character string.

16. The electronic device of claim 15, wherein the processor is further configured to perform:

determining the strength of the touches based on the area of the location of the touch.

17. The electronic device of claim 15, wherein the ranking is in direct relationship with the typing confidence if the input character string is a substring of the predicted character string.

18. The electronic device of claim 15, wherein the ranking is in inverse relationship with the typing speed if the input character string is not a substring of the predicted character string.

19. The electronic device of claim 15, wherein the typing speed comprises the average typing speed across a predetermined number of most recently typed characters.

20. The electronic device of claim 11, wherein displaying the ranked predicted character string comprises displaying the ranked predicted character string responsive to a determination that the ranked predicted character string is among a predetermined number of most highly ranked predicted character strings.
