The days of Minority Report and Iron Man style interactive holograms may not be that far off. Japanese engineers have recently developed a working prototype for "touchable" holograms. Their tech fires high-frequency laser pulses which last 1 millionth of 1 billionth of a second in order to create the illusion of physical contact with the holographic projection. While the scientists are specifically developing the tech with a forward focus on architecture and medicine, it's obvious that a number of other amazing applications are possible... video games! Seriously though... this is some amazing stuff, and we are lucky to be able to follow this kind of news as it develops! You can check out a video demonstration of the tech in the thread below.
