6.4 Fingertracking
Flysticks (max. 20) in Settings → Flystick. Tick the checkbox ’activate MultiUser func-
tion’. If you want to use a Flystick2 and a head target as data pair then you have to tick
the checkbox ’use head targets’ as well. Please refer to chapter B on page 250 for more
details on the output format.
6.3.2.1 Flystick Calibration
After assigning the Flystick to the ART radio transceiver, close the Flystick Settings dia-
logue and select Calibration → Body calibration.
In the appearing dialogue the body to be selected is named ’Flystick body 01’. Please
define the orientation of the body coordinate system relative to the body (default setting is
’due to body’). Make sure that all markers of the Flystick2 are seen by the cameras using
the Monitor 2DOF display which appears in the background.
Press Calibrate and the calibration starts within 5 seconds. Please refer to chapter 8.6.5.2
on page 177 for more information concerning body calibration procedure.
6.3.2.2 Flystick Output settings
The last step is to define where the Flystick data has to be sent to. In DTrack2 frontend
software, select Settings → Output. You can either select this computer (= remote PC) or
enter an IP address of another computer you want to send data to. By ticking the check-
box ’6df2’ you can define the Flystick data to be transmitted.
Please refer to chapter 8.5.7 on page 160 for more details.
Press Start to start the measurement. In order to see the tracking data you have to enable
the Flystick display by clicking Display → Flystick. Please refer to chapter 8.3.3 on page
135 for details.
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).
