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.

Three times the resolution, resulting in more precise tracking
Improved light filtering
Complete Computer Control – Provides everything you need to have control of your computer using only your head motion.
Natural Motion – Designed to complement the natural head motion you already perform when looking around. Moving your head less than a quarter inch easily maneuvers the cursor across your entire screen.
Dwell Clicking – You can left click, double click, drag, right click, and more - with our "dwell click bar" software application.
Virtual Keyboard - You can type on your computer screen with SmartNav's virtual keyboard program.
Switch Input – You can plug a click switch or a footswitch directly into the side of the SmartNav. With the Y Breakout Cable (included), you can plug in separate click switches for left and right clicking.
Exclusive Software Features:
Cursor Control and Clicking
Absolute Cursor Positioning Mode – allows a fixed relationship to be set up between the head location and the cursor position.
Separate X and Y Scaling – to accommodate users with limited horizontal or vertical range of motion.
Smoothing Control – to dampen unsteady head movement.
Key Activated – to have the cursor only move when you hold down a key.
Pause – to simply pause the system.
Hot Keys – for allocating keys of your keyboard to perform mouse clicks.
Profiles – for different users and for different programs (to fit the needs of many different users sharing the same computer).
Pause while typing – automatically stops cursor movement while typing, just like taking your hands off a mouse.
Gravity – aids in cursor positioning over buttons in Windows, fully customizable .
Mouse Cooperative Mode – for having a regular mouse connected at the same time.
Camera Display Window – for user feedback on dot location (see what smartNAV sees).
Inverting – for unique camera placement.
Precision Mode – for use with HotKeys or Switch Input, for extremely precise cursor movement.
