The integrated target library contains most hand target calibrations of
ART Fingertracking hardware. Perform a custom body calibration only
when the hand target cannot be identified automatically.
The body calibration can be assigned to a selected Hand ID the following way:
• turn on one Fingertracking device and place it inside the tracking volume
• run the target library identification by pressing Calibrate. The Short Name of the
corresponding hand target will be marked green
• mark the respective Hand ID from row ’H1...H4’ under selected hands by left-clicking
