I'm planning to buy a i-glasses HRV head mount display
and saw the Intertrax Head Tracker but it's too expensive.

I was wondering how those things work and how could I
do one of them with a PIC of course. I thought about
gyro and acelerometer but I'm not sure.

Does anyone have any experience with the I-glasses?
Good or bad?
