Abstract

A method and apparatus include detecting a first touch meeting a first threshold, which first touch is detected on a first physical key and displaying, without entering, at least a first character associated with the first physical key in an information entry field on an electronic device in response to the detecting.

Claims

1. A method comprising:

detecting a first touch meeting a first threshold, which first touch is detected on a first physical key;

displaying, without entering, at least a first character associated with the first physical key in an information entry field on an electronic device in response to the detecting.

2. The method of claim 1, further comprising detecting a touch meeting a second threshold, which touch is detected on the first physical key, and entering at least the first character of the at least one character as input.

3. The method of claim 1, wherein the displaying comprises previewing at least the first character while the touch meets the first threshold and discontinuing the previewing when the touch does not meet the first threshold.

4. The method of claim 3, wherein previewing comprises displaying at least the first character in a first format different than a second format of characters entered in the information entry field.

5. The method of claim 3, wherein previewing comprises at least one of:

displaying a faded version of at least the first character;

displaying at least the first character in a font that is different than the font of characters previously entered in the information entry field;

displaying at least the first character in a color that is different than the color of characters previously entered in the information entry field;

displaying a blinking, highlighted, or animated version of at least the first character;

displaying an underscored, italicized, or bolded version of at least the first character;

displaying a shaded, shadowed, enlarged, or shrunken version of at least the first character.

6. The method of claim 1, further comprising:

detecting a second touch meeting the first threshold, which second touch is detected on a second physical key;

displaying at least one character associated with the second physical key in the information entry field in response to detecting the second touch.

7. The method of claim 1, further comprising:

detecting a second touch meeting the first threshold, which touch is detected on a second physical key;

identifying a second character associate with the first physical key;

displaying at least the second character associated in the information entry field in response to detecting the second touch.

8. The method of claim 1, further comprising moving a text indicator through characters displayed in the information entry field based on relative movement of detected touches on a plurality of physical keys.

9. The method of claim 1, wherein the first threshold is a force threshold.

10. The method of claim 1, wherein the first threshold is a time threshold.

11. The method of claim 1, further comprising, when the touch is associated with a number during a phone application, displaying the number and at least one character associated with the number from a number-character mapping.

12. The method of claim 1, wherein the at least one character comprises a number and at least one character associated with the number from a number-character mapping.

13. The method of claim 1, further comprising:

when the touch is associated with a number in a phone application, displaying the number and one or more characters associated with the number;

detecting entry of the number;

identifying a first character of the one or more characters;

displaying at least one of the number and the first character when entry of the number is detected.

14. A computer-readable medium having computer-readable code executable by at least one processor of the portable electronic device to perform the method of claim 1.

15. An electronic device comprising:

a display;

a plurality of physical keys;

a processor operably coupled to the display and the plurality of keys and configured to;

detect a first touch meeting a first threshold, which first touch is detected on a first physical key of the plurality of physical keys;

display and not enter at least a first character associated with the first physical key on the display in an information entry field in response to the detecting.

16. The electronic device of claim 15, wherein the first physical key comprises a touch-sensitive element for detecting the first touch.

17. The electronic device of claim 15, wherein the first threshold is a time threshold.

18. The electronic device of claim 15, wherein the first physical key comprises a force sensor and the first threshold is a force threshold.

19. The electronic device of claim 15, wherein the processor is further configured to detect a touch meeting a second threshold, which touch is detected on the first physical key, and to enter at least the first character of the at least one character as input to the electronic device.

20. The electronic device of claim 15, wherein displaying comprises previewing at least the first character while the touch meets the first threshold and discontinuing the previewing when the touch does not meet the first threshold.
