Patent ID: 7342573

Claim:
A method, comprising: applying a manipulation signal to a predetermined location on a screen of an electronic device, while maintaining a seal intact, to communicate a predetermined command to said electronic device, wherein an electrostrictive polymer actuator is configured to form said seal and is attached or glued to said screen over edges of the screen; generating an actuator switching signal by a detector/amplifier/controller module in response to said manipulation signal, and providing said actuator switching signal to an actuator switching power supply; generating an actuator signal by the actuator switching power supply in response to said actuator switching signal, and providing said actuator signal to the electrostrictive polymer actuator; and changing a shape of said electrostrictive polymer actuator in response to said actuator signal, for causing a movement of the screen attached or glued to said electrostrictive polymer actuator, wherein said screen movement is for providing a haptic feedback signal regarding a successful transfer of said command to the electronic device.
