Abstract

A method of managing a keypad of a handheld electronic device comprises promoting a user whether a size of the keypad needs adjustment when the handheld electronic device is in a single hand operating mode. If the answer is yes, the handheld electronic device then detects a movement of a finger of the user on a touch screen thereof. When a movement of the finger along a diagonal direction of the keypad away from the keypad is detected, the size of the keypad is increased. When a movement of the finger alone the diagonal direction of the keypad toward the keypad is detected, the size of the keypad is decreased. When the movement of the finger is stopped and a “Done” button is pressed, the adjustment of the size of the keypad is completed, and the size of the keypad after adjustment is stored in a storage module.

Claims

1. A handheld electronic device comprising:

a keypad management system;

a storage unit for storing data and programs of the keypad management system therein; and

a processor;

wherein

when the handheld electronic devices is in a single hand operating mode for a keypad thereof, a size of the keypad is adjustable by the keypad management system under an execution of the processor.

2. The handheld electronic device of claim 1, wherein the keypad is a dial pad.

3. The handheld electronic device of claim 2, wherein a size of the dial pad is adjustable within a range between 2 cm² and 12 cm².

4. The handheld electronic device of claim 1, wherein the management system comprises a prompt module, a control module, an adjustment module and a storage module.

5. The handheld electronic device of claim 4, wherein the prompt module prompts a user of the handheld electronic device whether a size of the keypad in the single hand operating mode is to be adjusted.

6. The handheld electronic device of claim 5, wherein the adjustment module controls a range within which a size of the keypad is adjustable.

7. The handheld electronic device of claim 6, wherein the adjustment module adjusts the size of the keypad when receives commands from the control unit.

8. The handheld electronic device of claim 7, wherein the storage module stores the size of the keypad therein after the adjustment of the size of the keypad.

9. A method for managing a keypad of a handheld electronic device, comprising:

prompting a user of the handheld electronic device whether a size of the keypad needs adjustment when the handheld electronic device is in a single hand operating mode; and

detecting a movement of a finger of the user on a touch panel of the handheld electronic device to decide one of an increase and a decrease of the size of the keypad after the user decides to adjust the size of the keypad.

10. The method of claim 9, wherein when a movement of the finger on the touch panel along a diagonal direction of the keypad away from the keypad is detected, an increase of the size of the keypad is executed.

11. The method of claim 9, wherein when a movement of the finger on the touch panel along a diagonal direction of the keypad toward the keypad is detected, a decrease of the size of the keypad is executed.

12. The method of claim 9, wherein the increase of the size of the keypad has an upper limit and the decrease of the size of the keypad has a lower limit.

13. The method of claim 12, wherein the upper limit is 12 cm², and the lower limit is 2 cm² when the keypad is a dial pad.

14. The method claim 9 further comprising a step that when a stop of the movement of the finger and a press of a button are detected, the adjustment of the size of the keypad is finished and the size of the keypad after adjustment is stored in a storage module.
