Abstract: An electronic device includes a base, a touch screen display, a shape memory alloy and operational components. The touch screen display is connected to the base and moveable relative to the base and includes a display device and a touch-sensitive input surface overlying the display device and connected to a controller for determining a touch event to the touch-sensitive input surface. The shape memory alloy is disposed between the base and the display device and is configured to change shape in response to conduction of an electric current to cause movement of the display device relative to the base. The operational components include a processor between the base and the touch screen display. The processor is operatively connected to the controller, the display device and the shape memory alloy for causing conduction of current through the shape memory alloy in response to the touch event, resulting in movement of the display relative to the base.

Abstract: A handheld electronic communication device features an optically based user input device and navigation tool. In one embodiment, the optically based user input device features a translucent domed lens and a light source to illuminate a user's finger as the user slides his finger over the domed lens. In another embodiment, the optically based user input device features a translucent ball that the user rotates. In both embodiments, optical means are used to measure movement of the user's finger and translate that movement into a navigational command to the handheld electronic communication device. The optically based user input device is further configured such that an entry command is entered by depressing the optically based user input device.
