POINTING DEVICE

摘要

The present invention relates to a flexible and ergonomically well adapted solution for generating and feeding position related commands into a digital processor 400. A primary pointing device 100 controls the position of a cursor 411 on a digital screen 410 by means of primary position commands C¿1?. The primary position commands C¿1? are generated by a relative movement D?1¿¿1? D?1¿¿2? between the primary pointing device 100 and a substantially flat external surface, such as a tabletop or a mouse pad. The primary pointing device 100 is adapted to dock with a secondary pointing device 200, which may also control the position of the cursor 411 on the digital screen 410. Bearing registering user input controls 230a, 230b 232 in the secondary pointing device 200 generate secondary position commands C¿2?, which are fed to the digital processor 400 for causing the cursor 411 to move on the digital screen 410. Furthermore, the primary pointing device 100 is adapted to dock with the secondary pointing device 200. This allows the devices 100 200 to be used in a multitude of combinations, for instance, separated and as exclusive alternative to each other, separated however both influencing the cursor 411 or physically combined, with one or both of the devices controlling the cursor 411.
