Well I heard about this and thought “this will be great for home automation”, but I also know that someone was equally excited about using this to rob people of basic freedoms or being a fucking creep or both.
Comment on Humans can be tracked with unique 'fingerprint' based on how their bodies block Wi-Fi signals

Why would someone research something like this? God damn, like use your life for good, homie

If it’s your home why can’t you just have a camera or motion sensor. Rather than trying to adapt something that isn’t designed for the purpose.

Cameras require light, while radio waves works almost as well in darkness.
A motion sensor is an extra device that needs to be connected, have power and so on.
There are already radio wave motion- and room occupancy sensors where you can specify zones and so on, but if I could have personalized on top of that I’d take it.
Finally, using a thing for something useful other than its intended purpose is kinda fun.

Everything is incremental progress in some way.
I remember years back someone doing experiments with Wi-Fi to see if a room was occupied based on signal attenuation.
This just looks like an extension of that.
Not everything is a giant leap

I can imagine this being initially an accidental discovery like oh every time so and so’s body interacts with the WiFi signal it’s the same pattern… until someone starts exploring this further… and then some engineer or their manager started looking for applications for this. In my experience engineering researchers especially are very good with coming up with use cases for whatever tech they’re working with, with little ethical consideration.

I doubt it. You’d need to be looking really closely at the waveforms to notice this, so they were likely already doing something similar, like that research that can pinpoint where people are in a house based on their WiFi. They were probably already doing something creepy before they noticed that this was more straightforward than they expected.

Once you start playing with radiowaves and antenna you start noticing the intricate ways it plays with and around bags of water like bodies. I’m sure the original research on location/movement tracking was due to scientists trying not to get interference, later once they figured it out it was natural to see how much data they could get out of a radio interference profile.
I remember the original tech was going to be marketed as a way to tell if your old person (parent etc) had fallen down and stopped moving. Not the best use case, and then the privacy implications became clear. Once that happens the race begins to exploit the tech.
…But the eventuality here is something like a Star Trek tricorder that can take multiple vitals and detect irregularities from across the waiting room. Sensors that remember who was in a room and what settings they had. Etc. Some cool thing besides the bad stuff (microtarget those ads).

You think if people who publish their work publicly didn’t research things like this, they would just never be discovered?
At least this way, we all know about the possibility, and further research can be done to see what can mitigate it.
