1. Select the camera used for head tracking from the menu. A front-facing camera is recommended but not required, there are options for camera calibration and mirroring if you want to use a back camera.
2. Select "Calibrate camera" from the menu, hold the device in a comfortable position and touch the screen. You will have to do this once for every orientation.
3. If the preview appears upside down, touch it to flip.
This application is a demo for head tracking based 3D visualization. It was inpired by WiiDesktopVR by Johnny Chung Lee (http://www.youtube.com/watch?v=Jd3-eiid-Uw) and implemented as my MSc thesis.
Tested on a Motorola Xoom and a Samsung Galaxy S Plus. Model loading powered by Rajawali.

Sorry for problems on 4.0+, I never had the chance to test on such devices and the emulator is not an option for such CPU-intensive tasks. I disabled using the new face detection API so the main functionality should be right now.
What is more, I don't have any devices with front camera at all anymore, so don't expect big updates :-(
