1. 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;
a sensor operative to sense the action performed on said at least one input zone, and to generate signals in response to said action, said sensor being an optical position sensing device (PSD); and
a processor in communication with said sensor operative to process said signals for performing an operation associated with said at least one input zone.
