Abstract
A sensing device is provided for sensing data encoded on a surface. The device has a region identity sensor and a transmitter. The region identity sensor senses region identity data of the coded data when the sensing device is positioned or moved relative to a region of the surface. The region identity data is indicative of an identity of the region. The transmitter transmits the sensed region identity data to a computer system.
Claims6
A sensing device for sensing data encoded on a surface, said device comprising:
- a region identity sensor configured to sense region identity data of the coded data when the sensing device is positioned or moved relative to a region of the surface, the region identity data being indicative of an identity of the region;
- and
- a transmitter configured to transmit the sensed region identity data to a computer system,
- wherein the coded data includes periodic elements, the periodic elements being substantially identical marks within the coded data which assist the device in locating the coded data, the device further including a motion sensor configured to generate movement data on the basis of the device's movement relative to at least one of the periodic elements.
