Projection mapping theoretically adds a Holodeck-like level of immersion to simulations, but current projectors are simply too slow to keep up with fast-moving people. That won't be an issue if University of Tokyo researchers have their way. They've developed DynaFlash, a 1,000 frames per second projector that can keep up with just about any moving object. It can't beam images into thin air, like you see above (that's just for show), but it can seemingly do everything else -- even if you shake or spin an object very quickly, you'll still get the image where you wanted it to be. The trick involves adding a special controller to a DLP (digital light processing) projector that, combined with fast image output, delivers both high frame rates and low latency.
