Nbd, but moop means garbage at the burn. I agree this will happen, I suspect Apple is not only in the best position to exploit mmWave hardware but already well down the road in related interaction design. Apple Watch already offers limited physical sense-based life coaching in the form of hand washing duration tracking and feedback. Apple Watch’s assisted interaction with UI that quietly debuted in iOS 15 was an impo…
I assume moop is a slang term then? what's the burn? And yes, I am sure many companies are thinking (or at least have people in them thinking like this). A few issues are the legal and cultural framework (I am quite happy for my personal data to be shared with accredited Health (ie NHS) researchers, but not with the Apple Watch product manager) Epidemiology at this level is going to have transformative effects, but i…
At Burning Man, moop is an acronym for Matter Out Of Place, a reference to the leave no trace principal of the event. People will run after a small piece of material. Again, NBD, but in tech circles this might be the first thing people think of with that acronym.
I do think Apple captures plenty of meta data, but I do not know how much physical motion is getting sent back. One of the goals of the secure enclave was to store biometrics. And despite some notable concerns, the company has generally aligned its business model and branding to be privacy focused.
I can't think of another large company I'd trust more to handle this kind of information.
>Epidemiology at this level is going to have transformative effects...
The transformation is already underway. When Apple delivered Google Maps on iPhone with its pulsing blue dot, those with the technology instantly leapt ahead of those without it. I wonder how much stress has been relieved just from people knowing where they are.
I agree the technology can be misused, even to oppress. But this is true with any tech.
My concern is more about the disparity of those who have this tech and those that don't. The enhancements could start to show in a matter of years and quality of recommendations could coalesce into what will look like a new plane of daily living.

#164"One of mmWave's major advantages is its privacy-preserving nature. Because mmWave radar doesn’t process visual light, what it sees is not personally identifiable." Bullshit!
Perhaps they mean it skirts current privacy rules through legislative technicality.

#165I've been waiting for someone to finally make a consumer stud finder that works and this just might finally happen after this deregulation of the spectrum. The construction industry would hand over wheelbarrows full of money for a BLE phone-paired puck that located studs and pipes behind drywall. Someone could even sell a "pro" version that combined the data from multiple pucks to render a 3D point cloud of the insid…
Most studs have things (like drywall) nailed to them, and the nails are usually made of iron. So, all you need is a high-power rare earth magnet. I use a particularly strong refrigerator magnet. If you want to splurge (or are willing to couple trips to the coffee shop), you could buy one (or two) of these: https://www.homedepot.com/p/C-H-Hanson-Magnetic-Stud-Finder-... I was tipped off to these by the someone in the…
This doesn't work for conduit and plumbing. mmWave radar does.

The difference is the number of transmitters / receivers. TSA uses an array of them (from top to bottom) with narrow beams and they also rotate them and ask you to not move, so that effectively their number is considerably higher (ten of thousands), when reconstructing the image. Additionally, they use a higher frequency (160-400GHz), which additionally helps with resolution. See [1] and [2]. If we limit the number o…
You can reconstruct the images with neural networks even if you have little signal to guide.
This is true in the sense that NNs offer a convenient way to estimate a distribution of hidden values conditionalized upon visible values. That is an approximation of what is usually understood by "a reconstruction". I would argue that a reconstruction per se would only include parts for which the credible interval could be systematically bounded within a suitable tolerance threshold.

I recall the panic over that back in in the day, IIRC it was near-visible infra-red, not UV - if you didn't have sufficient IR filtering over the sensor, were using flash (and the flash included a decent amount of IR), and the subject was wearing something thin, you'd potentially get unintended skin detail with the IR reflection. As I understand more or less a solved problem on modern cameras such as on your smartpho…
I still have a Sony CD camera (as in disk not ccd) which has near IR and a IR led. Fun to play with for night recording (its intended use) and you can see though thin clothes a tiny bit but range is very limited. Skin patterns much less due to lacking contrast. Resolution in that mode is also lacking so detail is not really a thing. I can understand the problem and I think that is the reason my IR camera in my laptop…
Sony was forced to cripple the "night vision" feature of some cameras because it was too easy to abuse to see through clothing.

#169A technical error in one of the diagrams: Hall effect sensors are not binary, but one-dimensional, and are used so; their output voltage is directly proportional to the magnetic field strength. As for PIR sensors, fundamentally they’re certainly not binary, but I have no idea if they perhaps expose only a binary signal. A better example of a binary sensor might be an on/off switch.
thats a good point about the hall sensors. i'll update that. PIR sensors also output an analog signal, but in practice they are binary.
There’s a funny autocorrect typo in the Adams quote: Zaphod -> Zappos.
