This specific finding is minor, but its implications are not IMHO. From the article it appears the researchers consider this a discovery in effect. If consumer hardware is already capable (in many settings) of reproducing what were formerly research-level and industry-grade techniques, it may be a transformation in more areas of technology than would be obvious. I am very curious to see if there will be further findi…

The military/LEO is probably already envisioning a Daredevil like helmet with augmented-reality lenses that overlay non-line-of-sight threats in real time.

This is a very natural progression of technologies that escape industry/defense to get into the consumer's hand.

Didn't we already have a video of that? I don't remember the data sources used to generate the overlay, however. Was it multiple solders' helmets sharing their data, and/or perhaps even a drone from above?

I would be interested in seeing your visual mockups of how such a solution works on one of the article’s examples, like a car.

Like this: https://c8.alamy.com/compde/t0580m/der-verkehr-kurve-spiegel... Or this: https://cdn-01-artemis.media-brady.com/Assets/ImageRoot/DMEU... Reasonably common in difficult corners in Germany and Austria. Probably elsewhere too. The downside is that it's road infrastructure that has to be installed. The upside is that it works for everyone, including people in 20 year old cars or on bicycles.

You know what, that’s fair. That’s a good solution.

If it weren’t for the struggles of getting municipal infrastructure installed, I’d prefer it.

Ordinary WiFi can "see" through walls/corners with biometric fingerprinting of humans, https://gizmodo.com/researchers-issue-warning-about-tech-tha...

  Researchers collected WiFi signal recordings from nearly 200 participants as they walked through a WiFi field using different walking styles. The data was recorded from four different perspectives using both the BFI method and an older WiFi sensing approach relying on channel state information, or CSI. 

  “This technology turns every router into a potential means for surveillance,” said co-author Julian Todt in the press release. “If you regularly pass by a café that operates a WiFi network, you could be identified there without noticing it and be recognized later – for example by public authorities or companies.”

  The researchers are urging the IEEE, the organization that sets industry standards, to include stronger privacy safeguards in the upcoming 802.11bf standard, which is meant to standardize WiFi sensing applications.

These are very common in Spain too.

Smartphone grade lidar == FaceID ?

depends on what phone you have but LIDAR sensors are used for more than just faceID

Like what? Portrait mode? I have a Pixel 8 which I believe does something else to fake depth maps.
