Many will know of people who through illness or injury who used to fly etc... and no longer can, would like to be able to do so again (I am in the above).
Our project (my wife is now my hands) is to use a head based sensor and the APM to achieve some form of control. If there is anyone interested in this project and some genuine interest I'm sure my lovely wife will add to this blog.
To date we have built a stable quad with our own cnc cuttout components and Multiwii as the basic platform which will be moved to the APM once we have the headset (2 x accelerometers, 1 acting as a static reference for the dynamic accelerometer) finished and working as a PPM stream into the trainer port on our Hitec transmitter.
I know there are head trackers avaliable but these do not inject the full 5 channels we need. We are currently trialing some arduino code by Ian Johnston for the full 6 channel injection. Photo below is in level flight hands off. As above any interest feel free to comment. (the camera must have been at the right shutter speed to show the props as stopped)

I think I can help you. I have used an arduiono pro mini to read the ppm signal and pass through channels 1-4 and change channel 6 to channel 5 and add my own additional channels. The additional channels can come in from the serial port or what ever. The core of the code all runs off interrupts, there is no timing loop, it responds only to ppm input. It could easily be adapted for any Tx stick movement or a head mounted imu. I used tho DIY Ardu imu v2, and they are coming out with a v3 soon. I plan in hacking my new Hitec soon to add my own channels to my 6 ch.
Basically, any way you can get data into the arduino can be added to, or replace parts off the ppm stream.
I put a lot of time into this to get it working 100% reliably and would be happy to help you.
Good luck man.That's pretty hardcore stuff!!!!
