The ART Measurement Tool is a pointing device for measurement applications. In this specialised field it is very important to measure positions of points with a high degree of accuracy. The Measurement Tool is equipped with a measurement tip which can be, by way of the attached targets and using an appropriate DTrack2 module, located and tracked with the optical tracking system. Normally the position of the tool's tip is measured in DTrack's room coordinate system (fixed during room calibration). Optionally the Measurement Tool can calculate the position relative to a "reference body" (i.e. in its body coordinate system).
It is currently available in two different designs, see pictures below.
