How it Works?
SmartNav uses an infrared (IR) camera to track your head movements.


Infrared light is emitted from the LEDs and is reflected back to the imager by a corner cube reflector (3M safety material). This reflected light is imaged by a CMOS sensor and the video signal is passed to the preprocessing electronics. The video signal is thresholded against a reference level and all passing data is sent to the USB microcontroller to send to the PC for object tracking. In order to increase the signal to noise ratio an IR filter that passes only 800nm and above is placed between the imager lens and the outside world.
The SmartNav can image any IR source; typically this is reflective material or an active IR source such as an LED. A user may track many different objects by placing reflective dots or LEDs on the object. The SmartNav has a 45 degree field of view and anything being tracked must stay in that field of view.
Below is an actual size picture of our latest software. Key options are presented on this one main screen, though many more are available . For more information on the software's many features, please peruse section 4 of our online manual.
