Hand geometry calibration process After pressing Calibrate a countdown for the first
step of the calibration process begins.
In the first phase (calibration step 1)
•
all fingers have to be stretched out (see left picture in dialogue, refer to figure 6.23
on page 96)
• the thumb has to be spread away from the hand
•
do not spread the other fingers, keep them together. Take care, that there is no
space between them
•
do not move any finger nor the thumb during the first calibration phase
• it’s no problem to move the entire hand slightly
A progress bar shows the status of the calibration.
Z
If calibration step 1 fails, please check if modulated flash is activated
for one camera, and if the correct handedness and thimble set is se-
lected
After the first step has been completed a new countdown for step 2 is started.
During the second phase (calibration step 2)
•
keep the fingers stretched out (see right picture in dialogue, refer to figure 6.23 on
page 96)
•
keep the thumb spread away from the hand
• keep the other fingers close together
•
gently move all of your fingers up and down at the same time until calibration process
is finished. The thumb is still spread away from the hand and should not be moved
during this phase.
• do not bend or cross your fingers
Recommendation: Try to achieve an angle of approximately 60
◦
between up and down
position of the fingers.
Z
If calibration step 2 fails, please take care not to bend your fingers, and
not to move the thumb too much
