TRACKING DEVICE MENU
Use this drop-down menu to select the device used for head tracking. Nx Ocean Way Nashville can track head
movement from two sources: Camera and Nx Head Tracker.
CAMERA activates computer’s camera for head tracking. If more than one
camera is available, choose from the list.
NX HEADTRACKER selects the Nx HeadTracker that will be used by Nx
Ocean Way Nashville. Choose one HeadTracker from the list.
SENSOR FUSION mode uses the selected camera and one of the available
Nx Head Trackers together. Using these two kinds of sensors
simultaneously yields a tracking rate of up to 80 fps.
SETTINGS takes you to the HeadTracker application’s control panel. Use it
to reopen the application if it has been closed or if you want to tweak certain
HeadTracker controls.
CALIBRATE 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.
RATE indicates the rate of head tracking in frames per second (fps). The optimal rates are:
Camera: 25 fps–30 fps
Nx Head Tracker: 35 fps–50 fps
Sensor Fusion: 45 fps–80 fps
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.
