Abstract

An electronic device includes a controller circuit that is configured to display selectable indicia on a touch sensitive display device. The controller defines a default size and location of a plurality of selection zones on the display device that are each associated with different ones of the displayed selectable indicia. The controller responds to a touch signal from the display device that identifies a first touch location of a user object by increasing the size of a first one of the selection zones that includes the first touch location. The controller responds to the touch signal identifying that the user object has ceased touching the display device at a second touch location, which is within the enlarged first selection zone but outside the default sized first selection zone, by outputting a first one of the selectable indicia that is associated with the first selection zone.

the controller circuit is further configured to respond to the touch signal identifying that the user object has ceased touching the display device by decreasing the size of the enlarged first selection zone back to the default size.

3. The electronic device of claim 1, wherein:

the controller circuit is further configured to respond to the touch signal identifying that the user object has slid from the first touch location to a third touch location, where the user object has then ceased touching the display device and where the third touch location is within a third selection zone that is outside of the first selection zone, by outputting a third one of the selectable indicia that is associated with the third selection zone and by decreasing the size of the enlarged first selection zone.

6. The electronic device of claim 1, wherein:

the controller circuit is further configured to respond to the touch signal identifying that the first touch location is being touched by decreasing the size of all selection zones that are immediately adjacent to the first selection zone so that the enlarged first selection zone does not overlap any of the immediately adjacent selection zones having the decreased sizes.

7. The electronic device of claim 1, wherein:

the controller circuit is further configured to respond to the touch signal identifying that another touch location is being touched that is within the decreased size second selection zone by increasing the size of the second selection zone and decreasing the size of the first selection zone so that enlarged second selection zone does not overlap the first selection zone having the decreased size.

8. The electronic device of claim 1, wherein:

the controller circuit is further configured to respond to the touch signal identifying that the first touch location of the first selection zone is being touched by disabling a second selection zone that is adjacent to the first selection zone so that the enlarged first selection zone at least partially overlaps the disabled second selection zone.

9. The electronic device of claim 8, wherein:

the controller circuit is further configured to respond to the touch signal identifying that the first touch location is being touched by disabling all selection zones that are immediately adjacent to the first selection zone so that the enlarged first selection zone at least partially overlaps the disabled immediately adjacent selection zones.

10. The electronic device of claim 8, wherein:

the controller circuit is further configured to respond to the touch signal identifying that another touch location is being touched that is within the disabled second selection zone by increasing the size of the second selection zone, by enabling the second selection zone, by decreasing the size of the first selection zone, and by disabling the first selection zone so that the enlarged second selection zone at least partially overlaps the disabled first selection zone having the decreased size.

11. The electronic device of claim 1, wherein:

the controller circuit is further configured to display a numeric keypad with spaced apart indicia for each of the integer numbers from 0 to 9, to associate ten selection zones each with a different one of the displayed numbers, and to respond to the touch signal identifying that the first touch location within the first selection zone that is associated with the displayed number 5 by enlarging the size of the first selection zone and by decreasing the size of an adjacent second selection zone that is associated with one of the displayed numbers 2, 4, 6, and 8.

12. The electronic device of claim 11, wherein:

the controller circuit is further configured to respond to the touch signal identifying that the user object has slid from the first touch location to the second touch location, where the user object has then ceased touching the display device, by outputting an indication of the user'"'"'s selection of the number 5.

13. The electronic device of claim 12, wherein:

the controller circuit is further configured to respond to the touch signal identifying that the user object has slid from the first touch location to a third touch location, where the user object then ceased touching the display device and where the third touch location is within a third selection zone that is outside of the first selection zone and that is associated with the displayed number 4, by outputting an indication of the user'"'"'s selection of the number 4 and by decreasing the size of the enlarged first selection zone associated with the displayed number 5.

14. The electronic device of claim 1, wherein:

the controller circuit is further configured to display a qwerty alphabetic keyboard with spaced apart indicia for each letter of the keyboard, to associate selection zones each with a different one of the displayed letters, and to respond to the touch signal from the display device identifying that the user object has touched the first touch location within the first selection zone for a first one of the letters by enlarging the first selection zone and by decreasing the size of the selection zone associated with at least one of the displayed letters that is immediately adjacent to the first one of the letters, and to respond to the touch signal identifying that the user object has ceased touching the display device at the second touch location, which is within the enlarged first selection zone, by outputting the first letter.
