Head Tracking 3D

Head Tracking 3D demonstrates the ability of the front facing camera on Android devices to detect the face of the user to provide a head-tracking virtual reality display. The application has been developed and tested with Samsung Galaxy Tab 10.1 & Notion Ink Adam because of their fast processing speed with dual-core processor. The 3D rendering part of the App is based on my previous Android application "3D Depth Cues Demo" and the face detection is based on the Google Code project JavaCV using Haar-like features.

The App can however still be used with other Android devices, using the rear facing camera and inverting the X-axis, together with a mirror to reflect yourself or a photo of a human face.  Future updates will include support for more devices with front facing camera prior Gingerbread using the hardware specific API.
