DIY head tracker

Hi,

I designed and built my own head tracker, based on a Arduino Micro 5v and a gy-80 10 DOF IMU.
I'd like to build a wireless version, but before, I'd like to know if people are interested in this kind of product, as I'm willing to market it.

It will be 3 parts : the IMU device, fixed on the headphones, a "universal sender" which will allow to convert USB input peripherals to wireless, and the receiver part, plugged inside a USB port.
The IMU device will be battery powered (with AA or AAA batteries) and will support 100Hz positioning frequency.
The headtracker protocol is HATIRE compatible, and could be used out of the box with FaceTrackNoir.

Could you post a video please?
I use FaceTrackNoIR with just the PS3 Eye and the FaceTrack software with no problem

I use the same setup with satisfaction (5€ total cost)
@xStouf: congrats for your design! that's impressive!
what is the cost of your solution?
did you know the PS3Eye setup and did you benchmark it with your design?

Indeed, a video could give more information.

Here are some videos taken ingame with the actual wired tracker. You could see it is very accurate and speed is very good. I could follow an enemy without a problem. Please condiderate I was playing on a 15.4 laptop screen, so I tuned it for a large movement when I'm moving my head only a few degrees.

I tried to play Elite: Dangerous without it, but it's not possible anymore, it's working too well
Before working on it, I was using camera IR tracking, but I was not happy with it : too slow, not working well in night, even with an IR modded camera. I tried with XBOX360 and PS3 Eye cameras but was not happy with it. So I designed one with a proper IMU, that perfectly works in night.
Cost for the wired version is ~10$, cost for the wireless version would be around 30$ I believe.





The first video I made, when the tracker was not really calibrated yet, and curves were not fine tuned.

I, and maybe @RacingMat too, meant a video in 3rd person where we can see you while using the facetracker

Yes, I suspected this
I will upload one once I have done it, maybe tonight. My head + screen is not easy to capture

Here it is !

It was not easy, my camera is overheating when capturing in 1080p ^^
But I had time to show pitch yaw and roll before the thermal shut down ! Very precise, isn't it ?

Nice. Really accurate, also considering the low light

Have you checked out the EDTracker?, a very similar project to yours that is already commercially available. I have one and i have to say inertial tracking is much better (more accurate) than any of the optical infra red devices i have tried.

EDTracker works really well, it can be assembled by yourself.
