We already talked about the 3D floating vision by Pioneer a few days ago.

Just to recap:

Pioneer has developed a revolutionary system for 3D drawing. You use your finger to draw in the air. The procedure is as follows: you place your finger in a frame, you draw without touching anything with a depth perspective and this will be translated by a Pc onto the PC’s screen. At first sight, I don’t really see any real-life applications for this technology, but I’m sure that you can come up with dozens of possible fields in which this technology can be applied.
