Ph.D. student Jeremie Francone and Professor Laurence Nigay of the Laboratory of Informatics of Grenoble, EHCI Research Group (a French engineering human-computer interaction research team) have upped the ante on glasses-free 3D displays on hardware with cameras. They have created a glasses-free 3D display based on head tracking.
Instead of the display just putting a flat 3D image viewed via glasses, this application actually changes the display output by tracking your face on the device’s camera. In this case, the iPad 2 and iPhone 4. As your face moves, the picture will move accordingly to adjust your perception of the 3D model. Therefore, it gives you the feel of looking into another room.
According to their YouTube video description, their application does not use accelerometers (a tool that measures vibrations or motion of a structure) and it only uses the front camera. The concept is outstanding because it utilizes hardware you already have. So technically this application could also work on personal laptops or anything that supports a display and camera.
Personally, I think this mixed reality interaction is phenomenal — not only so simplistically clever, but it also has the potential to create new innovations on devices we already have. As far as I am aware, this application is still in research mode. So, no, there isn’t an app for this… yet!
