PS3 Eye Toy Camera
I’ve found the PS3 Eye Toy camera to be far superior to the other webcams for head tracking, picked one up from eBay. Latest version of OpenTrack includes a PS3 Eye Toy Camera driver.
AiTrack
Works by tracking your face so you don’t need to wear a hat, LEDs and so on. It’s like magic!
v0.6.5-alpha this recent release is the first version that works well enough for me to replace an Aruco paper tracker (the shame 
) It tracks 6DOF I can move forward, backward, left, right, up and down. It’s feels so natural - superb.

I’ve placed the webcam on top of my TV looking down. Choose 15fps for PS3 Eye camera, enter distance and custom brightness if lighting poor. 15fps is important as it reduces CPU load, better low light performance and in combination with EWMA filter and mapping properties in OpenTrack gives a perfectly smooth natural tracking.
