i3D – an overview of Head-Coupled Perspective
i3D is the summary¬† of Head-Coupled Perspective (HCP) on iOS devices. HCP control the front camera from your iPhone to get the face of the user in real time. This images will tells the application how the user is looking at the display. The application updates the viewpoint of the 3D scene accordingly, by offering¬† the user the illusion that he looks at a small window.
i3D has a few 3D scenes that you can notice¬† with HCP. It only relies on face tracking. This application is not¬† using the accelerometers or the gyroscopes.
The face tracking system does not recognize¬† and track the user face in every lighting condition. You must read the instructions from this application to get a good tracking.
Head-Coupled Perspective doesn’t create a stereoscopic display! It supplies a kind of monocular 3D display: the same picture is seen by both eyes. In the near future,maybe they will combined a¬† stereoscopic display for a better 3D effect.
i3D has been finished¬† by Jeremie Francone and Laurence Nigay at the Engineering Human-Computer Interaction (EHCI) Research Group of the Grenoble Informatics Laboratory (LIG), University Joseph Fourier (UJF).
