The second generation of the projection tech does color: http://www.k2.t.u-tokyo.ac.jp/vision/dynaflashv2/index-e.htm... And they can now do the tracking without the infrared paint: http://www.k2.t.u-tokyo.ac.jp/vision/MIDAS/index-e.html

Very cool, a sort of live-action cgi capability. Hope it doesn't easily scale out to larger spaces and crowds, or the current tech industry would soon have public spaces filled with ads projected on peoples belongings.

The target needs to be marked with infrared ink: you can project only on specific surfaces prepared in advance.

Edit: discard this comment, I misread the parent comment.

wow they even added shading, to do fake lighting effects

Not according to the comment that started this thread, which suggests that they no longer need the infrared paint.

Very cool. I do live projection work[0] and latency is always the killer with immersion. Anything higher than a 1000/90ms latency breaks integration at normal dancer movement speeds. 1000fps seems like overkill but it allows for very fast movement. 0. https://youtu.be/ggRcDQZWD_8?t=1281

Nice work :)

In 1899, H.G. Wells wrote "A Story of Things to Come", which later was adapted become the 1936 film "Things To Come". In the original story, the main characters mention being irritated by the advertisements projected onto the backs of the people they walk behind. Old idea, only now possible without image distortion.

Another use of a high speed projector would be to create real 3d display anywhere in a volume swept out by a moving surface. Objects will be translucent, but otherwise real 3d with wide viewing angles.

That’s an amazing idea. A naive approach would be to slice the volume into N surfaces (say, ~30 layers to stay above 30fps) but there is probably a much more efficient organic pattern or interlacing that would give good volume and angle coverage at much higher resolution - think of crumpled cloth blowing in the wind at speed.
