1. A pen-shaped scanning device for scanning a surface having coded data disposed thereon which is substantially invisible to the average unaided human eye, said device configured to determine at least two dimensions of a rotational orientation of the sensing device relative to the surface, the coded data being indicative of at least two dimensions of the rotational orientation of the sensing device, said device comprising:

  • an orientation sensor configured to generate, when positioned or moved relative to the surface, using at least some of the coded data, orientation data indicative of the at least two dimensions of the orientation of the sensing device relative to the surface;

    a transmitter for transmitting the orientation data to a computer system; and

    a region identity sensor configured to sense, when the sensing device is positioned or moved relative to a region of the surface, and using at least some of the coded data, region identity data indicative of an identity of the region, the transmitter being configured to transmit the region identity data to the computer system.
