This has probably been asked before.... Would it be possible to make a plugin that links a mobile phone's 'motion/gyro' sensor to the free look camera? Essentially replacing the mouse as the 'mover'. What I'm thinking is that with a phone on your head it can track your head movement and by using the free move with the phones motion/gyro sensors it will be a bit like TrackIR I suppose.
Use a Basecap, 3 IR-LEDs and some resistors and a 0815 webcam and look for open source tracking softwares
There is some way of doing it - http://forums.bistudio.com/showthre...or-under-10€&p=2673316&viewfull=1#post2673316 - from a thread where people are buying the gyroscope component and building their own thing, but that post describes a way of doing it using an android app and some other software. working in arma 3: http://www.youtube.com/watch?v=8WWb3Mc-Zgg
