Abstract

A method includes displaying a selectable feature on a touch-sensitive display of an electronic device, detecting a touch at a location within a target area associated with the selectable feature, and adjusting the target area based on a contact area of the touch and a magnitude of at least one signal when the touch is detected.

Claims

1. A method comprising:

displaying a selectable feature on a touch-sensitive display of an electronic device;

detecting a touch at a location within a target area associated with the selectable feature;

adjusting the target area based on a contact area of the touch and a magnitude of at least one touch signal when the touch is detected.

2. The method according to claim 1, wherein adjusting comprises resizing the target area.

3. The method according to claim 1, wherein adjusting comprises increasing the target area.

4. The method according to claim 1, wherein adjusting comprises resizing the target area based on a comparison of the contact area to at least one threshold value.

5. The method according to claim 1, wherein adjusting comprises resizing the target area based on a comparison of the magnitude of the at least one touch signal to at least one threshold value.

6. The method according to claim 1, wherein adjusting comprises resizing such that a change in size of the target area is proportional to a contact area of the touch plus a magnitude of the at least one touch signal associated with the touch.

7. The method according to claim 1, wherein adjusting comprises resizing such that a change in size of the target area is proportional to [a(contact area)+b(magnitude of the at least one touch signal)], wherein a and b are determined based on a comparison of the contact area to at least one threshold contact area and based on a comparison of the magnitude of the at least one touch signal to at least one threshold signal value.

8. The method according to claim 1, wherein adjusting comprises resizing target areas associated with other selectable features.

9. The method according to claim 1, wherein adjusting comprises increasing the target area and reducing sizes of target areas associated with adjacent selectable features.

10. The method according to claim 1, wherein the selectable feature comprises a key of a virtual keyboard.

11. The method according to claim 1, comprising:

detecting an end of the touch;

selecting the selectable feature when a last-reported touch location is associated with the adjusted target area.

12. The method according to claim 10, wherein the selectable feature is not selected when the last-reported touch location is not associated with the adjusted target area.

13. The method according to claim 1, comprising:

detecting an end of the touch;

selecting the selectable feature based on a last-reported touch location.

14. The method according to claim 1, comprising repeating adjusting until an input of a selectable feature is received.

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

16. An electronic device comprising:

a touch-sensitive display;

a processor coupled to the touch-sensitive display and configured to;

display a selectable feature on the touch-sensitive display;

detect a touch at a location within a target area associated with the selectable feature;

adjust the target area based on a contact area of the touch and a magnitude of at least one touch signal when the touch is detected.
