They're not directly imaging the human bodies in high res; they are getting blobs of movement and fitting a model of a human body onto it.

It doesn't look like it by looking at demo. It is way too detailed that would be physically possible.

You're not seeing the raw data, you're just seeing the resulting fitted model.

That model isn't showing the data underlying it, OP sucks a little.

It's like if I took a 3d textured model of something and stretched it over a kid's crayon drawing - the model here is much more detailed than the data that informs it, but all it's using is the positions.

I got it but you can't make up by example hand movements with the wavelength of 5 cm, demo looks way too good to be real imo

It would depend on the distance from the transceiver and the analysis.

Even with larger resolutions (poorer) you can use parallax and time distortion (movement and repeated sensings) to get better resolved.

I didn't see any finger positioning, but algorithms could easily infer the position of hands via inverse kinematics and position the maquette accordingly.

It would be helpful of OP to show the raw data visualization underneath.
