the available Nx Head Trackers together. Using these two kinds of
sensors simultaneously yields a tracking rate of up to 80 fps.

panel. Use it to reopen the application if it has been closed or if you want
to tweak certain Head Tracker controls.

defines your head position as the center position. Hold your head centered, look straight forward, and
click the button to let the system know where your center listening position is. Each time you start the system or
change either your position or the camera’s placement, you can recalibrate.

indicates the rate of head tracking in frames per second (fps). The optimal rates are:

Please note : The Sensor Fusion mode can be used by only one person at a time. That is, the camera must be
aimed at the person who is wearing the Nx Head Tracker.
