This is pretty neat.

This seems like an extremely advanced version of those sand tables at science centers that kids play with, where digging a trench in sand with your hand modifies the projection to affect virtual water flow.

The youtube video[0] from that page is especially interesting.

This is crazy awesome! And look at this one! I don't know if it comes from the same project, but looks cool. https://www.youtube.com/watch?v=c40cxE-dfPg

This is from 2016, but still very cool.

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

Yes, same research group: http://www.k2.t.u-tokyo.ac.jp/vision/MIDAS/index-e.html

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.
