<p>An integrated writing and computer input device (10) for alternately making notes on a surface (such as paper) and controlling a computer (20). The device (10) comprising a pen (12) for marking the surface, a pressure sensor (13) for determining if the pen (12) is in contact with the surface, motion sensing means (14) for sensing motion of the pen (12) relative to the surface, and a wireless transmitter (16) for transmitting a signal indicative of the motion of the device (10) to the computer (20). The motion sensing means may include a light/LED 141 and detector 142 for capturing light reflected from the surface. In a first mode of operation the signal indicative of the motion of the device (10) is transmitted to the computer (20) only if the pressure sensor (13) indicates that the pen (12) is not in contact with the surface.</p> |
