Abstract

A method of reducing user keypad errors includes sensing a user touch of a push button, storing a current state of the device in memory, displaying a graphic representing a new state of the device, where the new state corresponds to a press of the push button, and then sensing either a release of the push button or a press of the push button. The current state of the device is recalled from memory if a release of the push button sensed and the new state of the device is entered if a press of the push button is sensed.

Claims

1. A method of reducing user keypad errors, the method comprising:

sensing a user touch of a push button;

storing in memory a current state of a device;

displaying a graphic representing a new state of the device, the new state corresponding to a press of the push button;

sensing one of a release of the push button and a press of the push button;

recalling the current state of the device from the memory in response to sensing a release of the push button; and

entering the new state of the device in response to sensing the press of the push button.

2. The method according to claim 1, further comprising:

displaying the graphic representing the new state in a first location on a display in response to the touch of the button; and

displaying the graphic representing the new state in a second location on the display in response to the press of the button.

3. The method according to claim 1, wherein the displaying a graphic representing a new state of the device comprises:

displaying the graphic representing the new state in a first font size on a display in response to the touch of the button; and

displaying the graphic representing the new state in a second font size on the display in response to the press of the button, the second font size being different than the first font size.

4. The method according to claim 1, wherein:

the touch of the press button is a first range of movement of the button; and

the press of the press button is a second range of movement of the button.

5. The method according to claim 1, further comprising:

determining the touch of the press button by measuring a capacitance.

6. The method according to claim 1, further comprising:

determining the press of the press button by identifying a physical movement.

7. The method according to claim 1, further comprising:

executing an application representing the new state on a display in response to the touch of the button; and

removing the current state in response to the press of the button.

8. The method according to claim 7, wherein the application comprises one of:

a camera application;

a web browser application;

a picture view application; and

a sub-function.

9. A wireless device for reducing keypad errors, the device comprising:

at least one push button having a first state, a second state, and a third state;

a first sensor operable to identify the push button being in the second state;

a second sensor operable to identify the push button being in the third state;

a memory for storing states of the device;

a display; and

a processor communicatively coupled to the first sensor, the second sensor, the memory, and the display, the processor capable of;

receiving from the first sensor a signal indicating the push button being in the second state;

storing a current state of a device in the memory;

causing the display to display a graphic representing a new state of the device, the new state corresponding to the push button being in the second state;

receiving one of;

a signal from the first sensor indicating the push button returning to the first state; and

a signal from the second sensor indicating the push button being in the third state;

recalling the current state of the device from the memory in response to the first sensor indicating the push button returning to the first state; and

entering the new state of the device in response to the second sensor indicating the push button being in the third state.

10. The device according to claim 9, further comprising:

a first display portion for displaying the graphic representing the new state when the push button is in the second state; and

a second display portion for displaying the graphic representing the new state when the push button is in the third state.

11. The device according to claim 9, wherein the first state of the push button comprises:

a steady state of the push button.

12. The device according to claim 9, wherein:

the second state of the push button comprises;

a first range of movement of the button; and

the third state of the push button comprises;

a second range of movement of the button, the second range of movement being beyond than the first range of movement.

13. The device according to claim 9, wherein the push button comprises:

a capacitive portion.

14. The method according to claim 9, wherein the push button comprises:

a physically-moving portion.

15. A method on a wireless device for reducing operator errors, the method comprising:

in response to detecting a transition of a push button from a first state to a second state;

storing in memory a current state of the device;

placing the device in a temporary state corresponding to a function associated with the push button; and

displaying a graphic associated with the temporary state of the device;

in response to detecting a transition of the push button from the second state to the first state;

recalling the current state of the device from the memory; and

in response to detecting a transition of the push button from the second state to a third state;

designating the temporary state as the current state.

16. The method according to claim 15, wherein the displaying a graphic associated with the temporary state of the device comprises:

displaying the graphic associated with the temporary state of the device in a first location on a display.

17. The method according to claim 16, wherein the designating the temporary state as the current state comprises:

displaying the graphic associated with the temporary state of the device in a second location on the display.

18. The method according to claim 17, wherein:

the displaying the graphic in the first location on the display comprises;

displaying the graphic in a first font size and

the displaying the graphic in the second location on the display comprises;

displaying the graphic in a second font size.

19. The method according to claim 15, wherein the displaying a graphic representing a new state of the device comprises:

displaying the graphic representing the new state in a first state on a display in response to the touch of the button; and

displaying the graphic representing the new state in a second state on the display in response to the press of the button, the second state being visually different than the first state.

20. The method according to claim 15, wherein:

the touch of the press button is a first range of movement of the button; and

the press of the press button is a second range of movement of the button.
