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.

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.

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. - View Dependent Claims (10, 11, 12, 13, 14)

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. - View Dependent Claims (16, 17, 18, 19, 20)
