If you do want something that can look inside a building and determine the positions of people and objects, look up wifi slam [0] which was acquired by apple. It can use the wifi signals to map out the inside of a building and determine the location of objects inside. About a decade later, thanks to neural networks and other techniques, they can use wifi to determine pose information, they can create a rough skeletal model of a person that moves as you move. [1] The 2020 enhancements are a decent upgrade. [2]

I find this both fascinating and terrifying.
Setting obvious privacy implications aside, I'm surprised how good the animations look. I wonder if this could be developed further to enable cheap motion capture solutions for film/game studios. If it works in real-time then coupled with a game engine it could give you a direct in-camera look on what a cgi heavy scene might look like, without requiring (too) fancy hardware and also not adding distracting jump suits and reflective tennis balls and dot makeup all over the place.

The Mandalorian production comes to mind, they've been pushing this kind of direction hard.

Very cool stuff, thanks for sharing!

Never mind toilet paper shortages - I’ll be stocking up on tinfoil - for real this time! :-)
