Calibrate your VR920 Head Tracker
The last step is calibrating the head tracker. The iWear VR920 video eyewear computes head tracking
data through a series of 3 magnetic sensors and 3 accelerometers mounted inside the display enclosure.
As the magnetic fields around us change constantly and your eyewear must be periodically calibrated to
adjust for these fluctuations and their effect on the magnetic sensors. If you change the location of your
eyewear, even from one side of room to another or if you reposition items
that emit an electromagnetic field in its proximity, it should be recalibrated.
Magnetic fluctuations caused the rotation of the earth, will affect its magnetic
sensors slowly over a period of time. If you find its accuracy has changed –
recalibrate.
Tip: Do not position items with a large electromagnetic signature near
your video eyewear. Items like a sub-woofer sitting under a desk may
impact its tracking accuracy. These items do not cause damage and
accuracy will be regained by moving the affecting items several feet
away and recalibrating your eyewear.
► Open the iWear VR920 Calibrator application.
► Press the “Begin Calibration” button.
► Hold the eyewear facing your monitor, with the temples fully open.
Tip: Keep the temples fully open through the calibration process. The temple mounted headphones
contain magnets that can affect the calibration if their positional
relationship to the sensor changes.
► Rotate the eyewear fully through each axis; pitch, roll and yaw.
Tip: When moving the VR920 through its calibration movements it is
better to over rotate than under rotate. Less than full range
movement will lessen the accuracy of the calibration.
As you rotate the eyewear through each axis, the green indicator bars will
expend partially across the yaw, pitch and roll fields – they will not fill the panels completely.
