Abstract:
1. An apparatus for pointing spatial coordinates by a pointing tip, comprising a movable hand-held probe, having said pointing tip, and a portable base unit provided with a rotatably supported elongated arm, wherein said hand-held probe connects to said portable base unit by means of a cord or a wire via said elongated arm and wherein said base unit is provided with sensors arranged for measuring length or a change in length of said cord or said wire and rotation of said arm in at least one degree of freedom, and a computer-controlled processing device arranged for processing measuring signals delivered by said sensors into position data of said hand-held probe, characterized in that said hand-held probe further comprises an orientation device arranged for determining orientation data of said hand-held probe, and an interface device arranged for exchanging said orientation data with said computer-controlled processing device, and wherein said computer-controlled processing device is further arranged for processing said position data and orientation data into said spatial coordinates of said pointing tip of said hand-held probe by adjusting said position data of said hand-held probe with said orientation data of said hand-held device.
