FreeTrack 3 Points Cap Model With Integrated Batteries

A 3 point headtracking device to be used with FreeTrack ( http://www.free-track.net/english/ ).

EDIT: Use FreeTrackNoIR, it's the successor of FreeTrack (even supports headtracking without an IR device!):

Includes a battery compartment and a opening for a switch.



Designed to be put on top of a headphone.

If you have a Logitech G930 you can use my clip for the G930 to attach the device to your headphone:
