Flying cars, hoverboards and video chat - a very futuristic vision for the year 2015 was presented in the movie "Back to the Future Part II", released in 1989. Now, shortly before "Back to the Future Day" on October 21st, 2015, it is time to check whether reality has indeed kept up with the daring predictions of the 80s.
One of the technological innovations presented in this film was a huge 3D display. As far as this invention is concerned, Hollywood was almost right. Such displays will soon be possible. TU Wien and TriLite Technologies are presenting a display element which uses special micro optics and moving micro mirrors to project different pictures into different directions. This technology can be used to create 3D displays without the need for 3D glasses.
