1. A communication device, comprising:
- a dial pad including a plurality of touch sensitive switches;
a display; and
a microprocessor module;
wherein one switch of the touch sensitive switches provides a signal to the microprocessor module when a user breaks touch contact with the switch, the breaking of touch contact with the switch signifying that a keystroke sequence is completed.

Abstract
Interpreting keystrokes from the key pad of a device incorporates both key touch and key stroke into the decision to display a character, advance a cursor or execute a command. The device contains switches capable of determining when a keystroke cycle is completed. The switches may include touch sensitive switches or two position switches. The touch sensitive switches detect when a user breaks touch contact with the switch. The two position switches detect the completion of the keystroke sequence when the switch is pressed into the second position. Several different types of touch sensitive switches can be used including capacitive coupled, light sensing, pressure sensing and heat sensing.

9. A method for interpreting keystrokes from a plurality of touch sensitive switches, the method comprising:
-
monitoring for a keystroke from a switch; processing a first signal each time the switch is pressed and released; monitoring when a user breaks touch contact with the switch; and processing a second signal when the touch contact is broken with the switch, the breaking of the touch contact with the switch signifying that a keystroke sequence is completed. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for interpreting keystrokes from a plurality of two position switches, the method comprising:
-
monitoring for detection of a switch in a first position; processing a first signal each time the switch is in the first position; monitoring for detection of the switch in a second position; processing a second signal when the switch is in the second position; monitoring for detection of the switch in a starting position after it has been detected in the first position; and processing a third signal when the switch is detected in a starting position after it has been detected in a first position, the detection of the switch in the starting position after it has been detected in the first position signifying completion of a keystroke sequence. - View Dependent Claims (18, 19, 20)
