Sign me up for the security system. This seems like a total game changer if it's possible to do real human detection and tracking in a secure location.

I have a weirder utility for it: occupancy sensing in rooms. If it can detect breathing of humans reliably, then it solves a huge problem in having home automation with automatic lighting - particularly in bathrooms. I've never had a decent bathroom occupancy sensor (they all end up wanting to detect fairly large motions) - the obvious solution is AI with a camera but for obvious reasons no, but if a couple of base s…

Is there anything wrong with mechanical switches, beside the apparent (though negligible for me) improvement in comfort?

What kind of measures for privacy can be implemented for this? Technically or regulation wise.

Some active device equivalent to a mouse jiggler, retransmitting the signal and shifting the phase just enough to create the illusion of constant movement.

I grew up with a father who was obsessed with the idea that we were wasting electricity by accidentally leaving the lights on sometimes. As a result he's spent probably thousands in attempted energy saving devices which have all not worked and definitely would never save enough compared to the cost of them.

Which is why I think about these things despite this seemingly obvious solution.

And the fact that the guest bathroom when I visit his house still has no light switch but does have a cheap motion sensor which is annoying as hell.

From the abstract: "This paves the way for low-cost, broadly accessible, and privacy-preserving algorithms for human sensing." How much do we have to wait for the follow up paper: "Human identification through wifi signals" and then the patent for "Wifi as an identity tracking source for advertisement in public spaces" Technology advances make me sad those days...

> Human identification through wifi signals

It is already easy to track anyone who owns a smartphone.

I'm not sure "Privacy preserving" is the phrase that springs to mind with this tech.

Regulation wise we can hope the EU forces us to click through accept popups whenever we walk into a room.

This could be a boon for thieves, allowing them to scan for empty houses at night, so they know which ones can be more safely targeted.

It can also serve as a replacement for IR sensors in homes and keep thieves at bay

Wouldn't gait tracking be the obvious next step?

I was thinking the same thing
