Electronic device and tactile touch screen
First Claim
1. A touch screen display unit comprising:
- a base;
a display device coupled to the base and moveable relative to the base;
a touch-sensitive input surface overlying the display device for determining a touch event thereto; and
a plurality of shape memory alloy wires disposed between the base and the display device, a respective one of the plurality of the wires located near each of four corners of the display device, the shape memory alloy wires each configured to change shape in response to conduction of electric current to cause movement of the display device relative to the base,wherein the touch event causes conduction of electric current through at least one of the shape memory alloy wires determined based on location of the touch event, resulting in movement of the display device and touch-sensitive input surface relative to the base.

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.

15. A method of controlling an electronic device, the method comprising:
-
receiving a touch input at a touch screen display; determining a location of the touch input on the touch screen display; causing current conduction through at least one of a plurality of shape memory alloy wires disposed between a base and the touch screen display of the electronic device in response to receipt of the touch input, a respective one of the plurality shape memory alloy wires located near each of four corners of the touch screen display, wherein the at least one of the shape memory alloy wires is determined based on location of the touch input, and the current conduction resulting in a change in shape of the shape memory alloy to cause movement of the touch screen display relative to the base.
