Last month, French researchers Jeremie Francone and Laurence Nigay posted a videoshowing off a method for using head tracking by a device's camera to simulate three-dimensional scenes for the iPad, a concept in which Apple has expressed some interest.
As noted by MacStories, a new demo app from Francone and Nigay known as i3D has appeared in the App Store, giving users the opportunity to test out the technology on their own devices.
i3D is a free universal app running on the iPad 2, iPhone 4, and fourth-generation iPod touch. It contains a sample video image displaying a bounding box as it tracks the user's head location, as well as five demos showing the simulated 3D perspective that can be generated using the tracking.
