Abstract:
A sensing device for sensing region identity data and generating at least one of movement data and position data when the sensing device is moved relative to a region of a surface, the region identity data being indicative of an identity of the region, the movement data being indicative of the movement of the sensing device relative to the region, the position data being indicative of the position of the sensing device relative to the region, the surface having disposed upon its coded data indicative of at least one region associated with the surface, the sensing device including:a region identity sensor configured to sense the region identity data using at least some of the coded data; a motion sensor configured to generate at least one of the movement data and the position data; an identifier memory configured to store a sensing device identifier, the sensing device identifier being configured to distinguish the sensing device from other sensing devices of the same type; a communicator configured to communicate one or more of the region identity data, the movement data, the position data and the sensing device identifier to a computer system; and a timer configured to generate a time reference as the sensing device is moved relative to the surface region, wherein the communicator is configured to communicate time reference data to the computer sytem, the time reference data being indicative of the time reference of at least one of the movement data and the position data as generated by the timer.
