A few months ago, an interesting video surfaced that showed the concept of tracking a user’s head movement on iDevices. It was significant since it showed how 3D objects could rotate as you moved your head in different directions. Now the concept is available in the App Store as a new app, i3D.

Created by University Joseph Fourier, the free app gives an overview of what is called the Head-Coupled Perspective (HCP) on iOS devices. As the app tracks a user’s head (with the iPad’s front camera), it updates the perspective of the 3D scene accordingly, giving the user the illusion that he is looking at a small window.

According to its iTunes page, i3D:

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.

Here is the original video:

The free universal i3D app is available in the App Store. It works on the iPhone 4 and iPad 2.
