After data collection a calculation process is started which calculates the finger sizes from
the movement of the finger tips. The length of the thumb is derived by the finger lengths.
After successful calibration the ’
Geometry ’ entry under selected hands will be updated.
The entry in the column Cal. will turn into a green tick.
If the calibration terminates with an error message, double-check the calibration proce-
dure by clicking the button
Help .
When using Standard Fingertracking without tactile support, the next step is to activate
the data output. Please refer to chapter 6.4.6.8 on page 100. Otherwise you need to
assign the tactile devices, see to chapter 6.4.6.6 on page 98 for details.
5 Finger Simulation If you are using a three finger thimble set but would like to get data
for five fingers, tick the checkbox simulate 3 - > 5 . DTrack2 will simulate the data of the
two missing fingers by putting them parallel to the middle finger. By default, the checkbox
simulate 3 -
>
5 is unticked until you have carried out a hand geometry calibration.
Resetting finger tip sequence When the Fingertracking device has been removed
from the hand and afterwards is put on again by the same user, the system needs to
reset the correct order of the finger tips. To regain the correct sequence, the hand must
be kept still with all fingers stretched out and the thumb spread to the side (see first phase
of calibration process). When using two hands, both hands have to be separated by at
least 50 cm during this procedure.
Although the Fingertracking devices will compensate short synchronization losses inter-
nally, this procedure should be also used in the rare case when the Fingertracking devices
have lost synchronization (please refer to status LEDs on tables 6.5 on page 85 or 6.7 on
page 88).
6.4.6.6 Fingertracking Tactile Assignment
Open the sub-dialogue Fingertracking
→
Tactile Assignment to assign a tactile device to
the corresponding Hand ID . All available tactile devices will show up on the right side of
the window. This function is only applicable to FINGERTRACKING2 Tactile devices.

Please install an ART radio transceiver when using FINGERTRACK-
ING2 Tactile devices (refer to chapter 6.3.1 on page 80 for details).
Tactile devices are assigned the following way:
•
activate the support for tactile devices by ticking the corresponding checkbox tactile
Fingertracking active
•
mark the respective Hand ID from row ’ H1...H4 ’ under selected hands by left-clicking
•
mark the appropriate entry under available tactile devices (e.g. ’ FINGERTRACK-
