MIT develops a portable, high-resolution 3D imaging solution

So has everyone else, apparently. (I'm at Siggraph. (Off topic, I also learned I can't really see glasses-free 3D, but I'm not stereo blind. One eye may be slightly more dominant, so it could be an issue of 'calibration' I suppose.))

MIT's is definitely the coolest and best I've seen though, I don't think I've seen anything like it. Everyone else's is a light-based scanner or algorithms to 3D-ify mostly flat imaging. This amazes me beyond no end.

This is truly remarkable. I woke up in the middle of the night after reading this with a few improvements that can turn this into a human-equivalent level skin sensor for robotics.

Temperature: add something that changes color based on temperature.

Wetness: add some microchannels and watch them as they wick moisture into the material

Pain: introduce small ink packages that will burst if the material is damaged.

Vibration: add a microphone to detect pressure changes in the touched object, or if your cameras are fast enough just watch the surface as it moves up and down.

This could also be simply expanded to senses we don't have: Magnetism (ferrous particles), radiation(scintillation), PH level(litmus), detecting the presence of any chemical directly(specialised receptor), etc... this is revolutionary.

Using cameras behind a gel is a simple, non-obvious(to me), solution to the contact sensing problem. This is going to be used everywhere.
