Abstract:
Embodiments of the present invention provide a handheld device that comprises an information module for obtaining and/or receiving information pertaining to a surface adjacent to the device, and a position determination arrangement for determining at least one of a position and/or velocity of the handheld device. The position determination arrangement comprises a determination module configured to determine at least one of a relative position of the handheld device and/or a velocity of the handheld device based upon at least one of surface markings located on the surface adjacent the device and/or apparatus markings located on an input apparatus. The surface markings and the apparatus markings are configured to provide absolute position information.
