Those at Microsoft are constantly working on the development of technologies that will change the way we interact with the PCs of the future and the latest innovation theirs is a transparent 3D screen. We are not talking about a touch screen, but about a screen that the user can control from behind, that is, the interaction between him and the elements displayed on the screen is done by placing his hand behind it. The idea is interesting but for now very difficult to put into practice and very uncomfortable considering the rather strange way of interacting.
I have seen such interfaces in the sci-fi movies of the past years, but now they are becoming reality.
