6.4 Fingertracking
Description The ART Fingertracking system is a device that measures the position of
the hand and the finger bones. To achieve this, a 6DOF target is attached to the palm of
the hand and thimbles with 1 or 2 markers are worn on the measured finger tips. All other
information is derived from the kinematics of the hand, which are measured by a short
calibration process.
To use Fingertracking, a Fingertracking license has to be installed on the controller.
Please refer to chapter 8.4.1 on page 141 for details how to add license codes to your
controller.
There are two different Fingertracking versions available, Standard Fingertracking and
FINGERTRACKING2 Tactile (see figure 6.12 on page 84). All Fingertracking devices
consist of:
• a hand target unit for fixing on the back of the hand with IR LEDs (active markers)
for tracking (see figures 6.13 on page 85 and 6.16 on page 88).
