What if your iPad2 gave you the ability to see 3D images on the screen without special glasses?
Well, using the front facing camera to measure the location of the iPad2 holder’s head along with some software tweeks, some programers at Engineering Human-Computer Interaction Research Group have been able to create a sense of depth on the screen of the iPad2. A video showing some of the cool and practical views is show below.
The concept applies to devices like the iphone as well. The technology is by the group described as follows:
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.
Watch the entire video to see the possibilities. The 3D home screen (about 46 seconds into video) where you can hand apps on the side walls looks pretty cool.
