The EHCI Research Group has produced a demonstration video of 3D without glasses on an iPad 2 and iPhone 4 that will make your jaw drop to the floor! The possibility of glasses–free 3D hitting iOS devices has just become a reality.
Head-Coupled Perspective (HCP) on mobile devices allows to create a glasses-free monocular 3D display. It is based on a efficient head-tracker that uses the front-facing camera of the device. We use an off-axis projection in order to adapt the perspective of the 3D scene according to the head's position of the user. Such spatially-aware mobile display enables to improve the possibilities of interaction.
The videos are after the break, you have to see them to believe how good they are. When you have, let us know what you think in the comments!
