Head tracking. The easy and *Cheap way.
* Cheap if you already have a smartphone.
As you may be aware, there are a shed load of headtracking solutions out there. Some are expensive (TrackIR, I'm looking at you). Some are CONSTANTLY around the corner yet out of reach but could be the holy grail (Oculus rift). Some are very cheap but completely and utterly pants (FacetrackNoIR) and Some are a bit fiddly to build yourself but offer good results and can be bought prebuilt for a lot cheaper than TrackIR.
Worry no more.
There is a quick and easy solution if you have a smartphone.
Android: Go to Google Play store and Download 'HeadTracker' https://play.google.com/store/apps/details?id=com.frozenbacon.headtracker
It's the Lawrence Simmons version, there are others that dont work.
Follow the onscreen instructions on your phone.
Make sure you go to the settings and enable 'Transmit in Background' which will allow it to work with the screen off.
You'll also need software on your computer. I'm using OpenTrack.

You don't need to install, just extract to a folder of your choice and launch using the exe in the folder.
It really is easy to set up.
iPhone: Not a clue, go ask an iGenius or work it out yourself you trendy hipster

I'm very happy with it. Using just the pitch and yaw, disabled everything else. Having a play with the mapping sensitivity to get it right for me.
I've mounted the phone on my headset using an 'elastic band' made from the top of an old
clean sock. it lost its friend to the drier monster ages ago so is happy to have been found something useful to do other than catch sweat and dead toe skin.
Response seems very good and absolutely zero jitter which I have had with optical solutions. It doesnt wander noticeably. I went to the loo with it on my head and when I came back it was still good to go without having to hit the centre button (you'll need to set this in OpenTrack as well as 'toggle' to switch it on and off)
