“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.”

I wonder if it's real time? If yes then this is good for VR.

Here is an alternative Piped link(s):

Piped is a privacy-respecting open-source alternative frontend to YouTube.

I'm open-source; check me out at GitHub.

scientists bout to see me on the goddamned pot.

The reason this is good for privacy is because we don't need a new smart device to send other (like video) data away for heavy processing in the cloud.

We might instead be able to just update wifi routers to create local functionality.

Then it will depend on the router and the user configuration what actually happens with that data.

The user can have full local control…. Except neighbours wifi could be spying and so could someone with a wifi device in a car. But if putting a faraday cage around peoples exterior walls (combined with an underground physical cable to an internal extender for phone and roaming while insid) becomes a thing then it looks it could be a great system theoretically.

Gotta wait to see how it might look in practice though.

I heard that they can analyze window glass to get audio recordings because as a slow moving liquid, vibrations in the air leave an imprint on the glass.

Sounds like Fringe Science to me, honestly

Yes that's possible and it has some years but there's some conditions. The glass needs to have a sticker onto it for the trick AFAIK is to reflect a laser or infrared light onto it and track the less than milimétric vibrations of it and depending on where is the sticker and how big is the window it affects the quality of the recording. Given this wifi trick I think it would have to do with signals not passing through water clearly or some thing on the likes and more over it should need some specific equipment to pull out the trick, I don't imagine you could just hack a router and patch surveillance in the firmware.

I now have no sense of privacy anymore
