Abstract
A data input device including an optically generated image of a data input device, the image including at least one input zone actuable by an action performed thereon by a user, a sensor operative to sense the action performed on the at least one input zone, and to generate signals in response to the action, and a processor in communication with the sensor operative to process the signals for performing an operation associated with the at least one input zone.
Claims46
A data input device comprising:
- an optically generated image of a data input device, said image comprising at least one input zone actuable by an action performed thereon by a user;
