13 . The joystick assembly as claimed in claim 12 , wherein the rotary potentiometer is inactive as the joystick is moved between the first position and the second position, and is active as the joystick is moved between the second position and a maximum travel position for detecting motion of the joystick between the second position and the maximum travel position.
14 . The joystick assembly as claimed in claim 11 , wherein the potentiometer comprises a linear potentiometer.
15 . The joystick assembly as claimed in claim 11 , further comprising a second potentiometer, a first slide member for coupling the joystick to the potentiometer and a second slide member for coupling the joystick to the second potentiometer.
16 . The joystick assembly as claimed in claim 15 , wherein the second slide member overlaps the first slide member and is oriented perpendicularly to the first slide member, the joystick extending through slots disposed in the first and second slide members.
17 . The joystick assembly as claimed in claim 15 , further comprising a sliding base for coupling the joystick to the first slide member and the second slide member.
18 . The joystick assembly as claimed in claim 15 , further comprising a sliding base coupled to the joystick, the potentiometer and the second potentiometer engaging the sliding base for detecting movement of the sliding base.
19 . The joystick assembly as claimed in claim 11 , further comprising a spring assembly for resisting movement of the joystick.
20 . A hand-held communication device, comprising:
a housing having a first surface and a second surface, the housing being configured to be held in a hand of a user so that the first surface generally faces toward the user while the user holds the housing and the second surface generally faces away from the user while the user holds the housing;
a navigation key assembly disposed in the first surface of the housing; and
a joystick assembly disposed in the second surface of the housing, the joystick assembly including a joystick folding between a first position within the housing for storage of the joystick and a second position extending from the housing for manipulation by the user,
wherein the joystick assembly and the navigation key assembly cooperate for controlling a function of the hand-held communication device.
21 . The hand-held communication device as claimed in claim 20 , wherein the joystick assembly further includes a potentiometer coupled to the joystick for detecting motion of the joystick.
22 . The hand-held communication device as claimed in claim 21 , wherein the potentiometer comprises a rotary potentiometer.
23 . The hand-held communication device as claimed in claim 22 , wherein the rotary potentiometer is inactive as the joystick is moved between the first position and the second position, and is active as the joystick is moved between the second position and a maximum travel position for detecting motion of the joystick between the second position and the maximum travel position.
24 . The hand-held communication device as claimed in claim 21 , wherein the potentiometer comprises a linear potentiometer.
