Tracker Calibration
The last step in the setup process is to calibrate the Wrap Tracker. Of course, if you
have chosen not to connect your tracker at this time, you can by-pass this step.
Your Wrap Tracker uses multiple sensors for calculating movement and positioning,
including magnetometers. Magnetometers are influenced by magnetic fields and
certain electronic devices and therefore require an initial calibration and re-
calibration whenever its operating environment changes. The Tracker also contains
gyroscopic sensors and these require zeroing when initially used and whenever the
Tracker is connected to a different computer system.
Note: Certain metals and electronic devices create electromagnetic fields that will influence the
Tracker. Typical examples include, metal framed buildings and speakers, including a sub-woofer
sitting under your desk.
Note: For the best calibration results, the video display should be active during the calibration process
and its earphones anchored in the holder along the stems to maintain a consistent orientation
as they too contain magnets.
 Run the VR Manager application.
The first time VR Manager is run, it will sense the Tracker and advise that its Gyros
require zeroing. The gyros zeroing process can also be initiated manually from the
VR Manager’s “Misc. Tools” tab.
 When the VR Manager’s Zero Gyros screen appears, place the Wrap eyewear on
your desk facing your computer and do not move them while the gyro zeroing
process is being performed.
 Follow the on-screen instructions.
Upon completion of the gyro zeroing process, the VR Manager program will
complete loading and present you with its Calibration screen.
