Those short-throw Sony projectors we showed you can be placed very close to a wall, compensating for distortion to present a rectangular image. That's a neat trick. But researchers at the University of Tokyo have done Sony one better, by creating a system that can project images onto moving surfaces, like billowing fabric. Take a look at this:
The U. of Tokyo's Ishikawa Watanabe Laboratory developed the technique, which they call "Dynamic projection mapping onto deforming non-rigid surface[s] using a high-speed projector." To pull it off, they use two technologies:
The first technology is a high-speed projector [called] "DynaFlash" that can project 8-bit images up to 1,000 fps with [a] 3 ms delay. The second technology is a high-speed non-rigid surface tracking at 1,000 fps. Since the projection and sensing are operated at a speed of 1,000 fps, a human cannot perceive any misalignment between the dynamically-deforming target and the projected images.
