They used a commercial 6DOF head tracking solution from Naturalpoint called TrackIR 4 Pro. The manufacturer promises:

Experience real time 3D view control in video games and simulations just by moving your head! The only true 6DOF head tracking system of its kind. TrackIR takes your PC gaming to astonishing new levels of realism and immersion!

The tracker is supposed to work at 120fps, and Jyri’s video demo was convincing, so it looks like an interesting and cheap mocap tool.

The dissertation presents a good overview of various types of voice analysis techniques, and suggestions for various ways of using the voice as a controller for synthesis. I am particularly interested in his suggestion of a GDIF namespace for structuring parameters for voice control:

/gdif/instrumental/excitation/loudness x
/gdif/instrumental/modulation/pitch x
/gdif/instrumental/modulation/formants x1 x2
/gdif/instrumental/modulation/breathiness x
/gdif/instrumental/selection/phoneticclass x

Here he is using Cadoz’ division of various types of instrumental “gestures”: excitation, modulation and selection, something which would also make sense for describing other types of instrumental actions.

I am looking forward to getting back to working on GDIF again soon, I just need to finish this semester’s teaching + administrative work + moving into our new lab first…
