Vuzix Wrap 920 VR Bundle - Manual (Page 39)

The Set Zero button establishes the Tracker’s home or centered position. As you
move your head you will see the indicators and values in the Yaw, Pitch and Roll
indicators reflect movement relative to that centered position.
Drift
Some degree of drift on the Yaw axis is normal.
The Wrap Tracker provides an auto-centering capability that will automatically
compensate for most drift while the Tracker is in use. Occasionally, before starting a
session you can use the Set Zero button to re-center the Tracker for optimum
calibration. You do not have to go through the entire calibration process to use the
Set Zero function.
Vuzix Extensions Monitor
Stereoscopic 3D video and head tracking require support specific to each application.
This may be incorporated directly into the application (native support) or externally
through a Vuzix Extension.
Vuzix Extensions are accessed and managed through the Monitor section of the VR
Manager. The Title list shows all of the Vuzix Extensions and their current status.
