Technology

For VR I don’t see why we wouldn’t use a variety of other technologies before we ever use WiFi. The main issue with the WiFi thing is going to be polling rates and interference (which limits polling rates). They’re also using a neural net here which requires both processing power and time so there’s latency far beyond VR uses. That’s without talking about tracking that would be needed for higher spatial resolution which this also doesn’t have currently. So it’s not impossible to use this, just not currently practical or even close.

The real solve to that stuff is just an improvement on existing tech or maybe Lidar. With the progress that has been made on the Quest with hand tracking, I’d bet their next goal is body and face tracking so you’ll see this soon.

As for the government having this, I doubt they really need to have it this specific to track poses or body parts. If you have a cell phone on you, they likely know exactly where you’re at in a room. If you don’t, I’m betting they have access to other important data. Motion detection, number of people, room shape and some contents, interference sources.

I literally just have my machine ping my phone every ten seconds. Surprisingly effective presence detection.

A good hobby is a wonderful thing, indeed!

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.

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.

Here's the summary for the wikipedia article you mentioned in your comment:

TEMPEST is a U. S. National Security Agency specification and a NATO certification referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations. TEMPEST covers both methods to spy upon others and how to shield equipment against such spying. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC).
