Calibrator
Vuzix trackers use multiple sensors for calculating movement and
positioning, including magnetometers. Magnetometers utilize the earth’s
magnetic field and are influenced by nearby objects that influenc e the
magnetic field such as items containing magnets, large metallic masses
and certain electronic devices. To compensate for these influences the
tracker must be calibrated. And, as magnetic influences fluctuate over
time, it should be re-calibrated periodically or whenever its op erat ing
envir onment changes.
Note: Certain metals and electronic devices create electromagnetic fields
that will influence the Vuzix Tracker. Typical examples include, metal
framed buildings and speakers, including a sub-woofer sitting under
your desk.
Calibrating Your Tracker
Start the VR Manager application with your eyewear and tracker
connected to your comp ut er.
Note:
For the best calibration results, the VR920’s video display should be
configured to display an image, 2D or 3D, during the calibration
process. Its earphones should be anchored in the holder along t he
stems to maintain a consistent orientation as they too contain
magnet s.
1. Open the VR Manager program and press the “Begin Calibration”
button.
