“We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input.”

Lets hope the government is transparent about its use of this technology.

All the information you want to know is available at: REDACTED

Article is from a year ago. Government tends to be ahead of the curve. As an uninformed guess, they have been using it in high value situations for 4+ years.

(Dear FBI, the above is a guess based on public information. I don't know shit.)

Government tends to be ahead of the curve.

I dunno what world you're living in, but I live in a world where police still do nearly all their work with pencil and paper and if you want to talk to a police officer, no you can't talk to them on the phone or send an email. You'll have to have a meeting face to face.

Sorry, I don't mean the police.

Actually, police do tend to be reasonably ahead when technology is invasive. I've heard many stories about them seeing through walls with other technology. They also tend to like face-tracking, which is pretty advanced. They just are really far behind on technology that could be used to hold them accountable.

Israel has been using a similar system since at least 2022:

It's pretty likely that they have shared this system with their closest allies, similar to how the Trophy missile defense system found its way onto German and American tanks.

By the way, those throwable cameras mentioned at the end of the article have been available to the IDF since 2005.
