You can now try out the technology that made a lot of noise and popularized the concept of tracking the user's head movement in order to figure out their head angle and render on-screen graphics accordingly. The resulting effect was a show-stopper, 3D objects on the screen seemingly rotating as you change your viewpoint, giving out false impression of a 3D display.

"i3D is an overview of Head-Coupled Perspective (HCP) on iOS devices. HCP uses the front camera of the device to track the face of the user in real time. This information tells the app how the user is looking at the display. The app updates the perspective of the 3D scene accordingly, giving the user the illusion that he looks at a small window."

i3D contains several 3D scenes that you can observe with HCP. It only relies on face tracking. It does not use the accelerometers or the gyroscopes.

The face tracking system does not detect and track the face in every lighting condition. Read the instructions in the app to get a good tracking.

Head-Coupled Perspective does not create a stereoscopic display! It provides a kind of monocular 3D display: the same picture is seen by both eyes. In the future, it might be combined with a stereoscopic display for a better 3D effect.
