Provided is a scanning device for scanning a surface having coded data disposed thereon which is substantially invisible to the average unaided human eye. The device is 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. The device includes 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 pressure sensor to facilitate activation of the orientation sensor when a nib of the pen-shaped device is pressed against said surface. |
