Technology

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.

Home automation nerds would also cream their pants if they could get their hands on this. Imagine you could use your existing wifi router to detect presence in your home. Say goodbye to shitty IR sensors that forget about your existence within 3 seconds, no more finicky radar modules that are either too sensitive or not nearly sensitive enough.

Same, but the fantasy miniatures are sex toys and the paint is my butt.

In more than one sense, yes.

I lick that 👍

paint myself in lead paint to become invisible. got it. /s

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.)

Here's a video summary of the paper I thought did a good job too from two minute papers.

... that you CANT see through walls? Seems like a downgrade to me...

it became understood that merely because someone can get a photo of you they have the legal right to do so.

What jurisdiction is this true? There are certainly times that there is an expectation of privacy and getting a photo of you would be illegal. Easy example: and owner of a store can't photo you in the dressing room, the even tho they could put a camera in there. It's the same thing here, there is an expectation of privacy in your home (or for many enclosed and private spaces), so this kind of "picture" would likely already be a violation.

I'm an EE, and I have serious doubt about this actually working nearly as good as they are putting it. This sort of stuff is hard, even with purpose built radar systems. I'm working with angle estimation in Multipath environments, and that shit fucks your signals up. This may work it you have extremely precisely characterised the target room and walls, and a ton of stuff around it, and then don't change anything but the motion of the people. But that's not practical.

Here's what they're putting in the goggles that Infantrymen wear now.

I don't care to guess what the drones are packing.

The tech is even far older than the article. I remember seeing this being demo'd at least a decade ago. Though, it looks like the fidelity has improved significantly from the early proof-of-concept videos that were floating around for a while.
