Step 5: Tracker Calibration
The STAR 1200 is equipped with a Wrap Tracker, a 3 degree of freedom
(DOF) IMU (Inertial Measurement Unit), more commonly known as a
head tracker. Most tracker enabled applications support pitch, yaw and roll.
The Wrap Tracker utilizes a series of nine sensors (3-accelerometers, 3-
gyros and 3-magnetic field sensors). As magnetic field sensors are sensitive
to your environment their performance is affected by magnetic interference
from nearby metal and electrical objects as well as the earth’s natural
magnetic fields. A calibration process helps to minimize external influences.
Tip: Take note of potential magnetic interference nearby to where you are using your
tracker-enabled eyewear. Hidden objects, like that huge base speaker under
your desk or other objects can sometimes be relocated for increased accuracy
and reliability.
To calibrate the tracker on your Wrap eyewear:
§ Connect your STAR 1200 with its tracker to your computer.
§ Launch the VR Manager application.
If this is the first time you have started VR Manager with the Tracker
attached, a Zero Gyros screen will appear.
§ Place the Wrap eyewear flat on your desk facing your computer.
§ Do not move the eyewear while the gyro zeroing process is being
performed.
§ Follow the on-screen instructions to zero the Tracker’s gyros.
Once the gyros are zeroed, VR Manager will present you with its Calibration
screen.
