“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.”
Absolutely ludicrous to paint this development as anything but the wet dream of both a burglar and a police state.
Also VR nerds. Current tracking is either based on the headset, so you can’t move your arms unless the headset can see them, or your arms have to be seen by lighthouses, or you rely purely on gyroscope and accelerometers for tracking, which tend to drift. So either you have blind spots, have to deal with occlusion, or will slowly drift and have to recalibrate periodically. Wifi-based tracking seems like a neat idea tbh.
Edit: considering wifi is just photons that aren’t wiggling fast enough for us to see, I’d be surprised if the government doesn’t already have this technology behind closed doors.
I mean you can look through my walls if you want, but don’t come crying to me if you don’t like what you see.
(I’m painting fantasy miniatures. They’re for a friend.)
Henceforth, the building code shall make mandatory that every room be perfectly grounded Faraday cages (/s).
Still, imagine lethal drones integrated with that technology (of course, they already have infrared, maybe even some adequate wavelength of X-rays).
Nevertheless, pretty cool to see how far we can take preexisting technology with the help of some deep learning layers.
Umm, article from Jan 19, 2023. I remember seeing it then. Is there anything new on this?
The paper: [Submitted on 31 Dec 2022] - I’m not sure if it’s out of prepublication yet.
DensePose From WiFi - https://arxiv.org/abs/2301.00250Here’s another tidbit from July 2, 2023 DensePose from WiFi - See through the walls. - https://www.linkedin.com/pulse/densepose-from-wifi-see-through-walls-alejandro-fernández
And another from July 25, 2023 Revolutionary Applications of DensePose From WiFi: Enhancing Corporate Security and Empowering Military Tactical Teams - https://www.linkedin.com/pulse/revolutionary-applications-densepose-from-wifi-enhancing-zack-hamm
Here’s a video summary of the paper I thought did a good job too from two minute papers.

Lets hope the government is transparent about its use of this technology.
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.)
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.
This article is a year old. Do we have posting standards in here?
Sorry, I didn’t notice the date when I posted. I can take it down if requested.

Lead paint coming back into fashion.
