Do you remember the computer interface of the future from Minority Report? (Here is a trailer if you haven’t seen it). It seems like we might not be too far from this becoming a reality. Last week, I watched a researcher search a map, play a platformer, and completely control a computer with his hands instead of a mouse. This was one of twenty cool exhibits at Techfest, an event where Microsoft Research demos some of their projects for the public (the event is also called “the & in R&D,” as its purpose is to facilitate the transition from pure research to development). Many of the demos were quite exciting, so I just wanted to share my thoughts about a small subset of the cool things I saw.
