    Abstract: A primary pointing device controls the position of a cursor on a digital screen by means of primary position commands (C1). The primary position commands (C1) are generated by relative movement (D11; D12) between the primary pointing device and a substantially flat external surface, such as a tabletop or mouse pad. The primary pointing device is adapted to dock with a secondary pointing device, which may also control the position of the cursor on the digital screen. Bearing registering user input controls in the secondary pointing device generate secondary position commands (C2), which are fed to the digital processor for causing the cursor to move on the digital screen. Furthermore, the primary pointing device is adapted to dock with the secondary pointing device.
