The german company Newsight is developing the so called “autostereoscopic” displays. With this technology it is possible to look at a real footage scene or a 3D scene from different angles by moving your position in real space without wearing stupid googles.
You see the object with a similar effect which you would get with 3D glasses that are used in combination with the corresponding content to create a three dimensional illusion. This video shows the reaction of the people seeing one of these displays in action.

These illustrations show what it’s like to look at autostereoscopic displays. Pretty cool I’d say - it would be interesting to develop interactive installations with it, as they are available up to 57″ (1,3 m width, 0,8 m height) in full HD!
