The National Institute of Information and Communications Technology (NICT) and Kobe University have jointly developed a thin-panel type device, which forms 3D images in the air. "This device renders transparent, reflected images. Unlike holography, the device needs no special optical system other than itself and features color image production," said a spokesperson. Just by setting a display (or a subject to be shown) under a glass table and laying this device over the table, a "3D display" can be created.
I'm sure there's a purpose for this I just can't figure out it is. It basically takes an existing 3D object and redisplays it in 3D. Call me old fashioned but why not just look at the original?
