摘要

An apparatus for pointing spatial coordinates, comprising a movable hand-held probe, having a pointing tip, and a portable base unit provided with a rotatably supported elongated arm, wherein the hand-held probe connects to the portable base unit by means of a cord or a wire via the elongated arm and wherein the base unit is provided with sensors for measuring length or a change in length of the cord or the wire and rotation of the arm in at least one degree of freedom, and computer-controlled processing means for processing measuring signals delivered by the sensors into position data of the hand-held probe.
