MIT Is Building a Health-Tracking Sensor That Can See Through Walls (technologyreview.com)

Rachel Metz reports via MIT Technology Review: Imagine a box, similar to a Wi-Fi router, that sits in your home and tracks all kinds of physiological signals as you move from room to room: breathing, heart rate, sleep, gait, and more. Dina Katabi, a professor of electrical engineering and computer science at MIT, built this box in her lab. And in the not-so-distant future, she believes, it will be able to replace the array of expensive, bulky, uncomfortable gear we currently need to get clinical data about the body. Speaking at MIT Technology Review's EmTech conference in Cambridge, Massachusetts, on Wednesday, Katabi said the box she's been building for the last several years takes advantage of the fact that every time we move -- even if it's just a teeny, tiny bit, such as when we breathe -- we change the electromagnetic field surrounding us.

Her device transmits a low-power wireless signal throughout a space the size of a one- or two-bedroom apartment (even through walls), and the signal reflects off people's bodies. The device then uses machine learning to analyze those reflected signals and extract physiological data. So far, it has been installed in over 200 homes of both healthy people and those with conditions like Parkinson's, Alzheimer's, depression, and pulmonary diseases, she said. Katabi cofounded a startup called Emerald Innovations to commercialize the technology and has already made the device available to biotech and pharmaceutical companies for studies.

      To watch the "general public", you need to install this in places, where this public resides — and sleeps. Not only is it difficult, it is also pointless — what purchase is there in knowing, Joe Shmoe is not really asleep?

      In prisons the population is already under surveillance and has no right to privacy. It is also assumed to be up to no good at all times. These two factors make the prison use-case easier to explain and justify than even that of the hospital...

  7. Anybody made it find the big water pipe in wall? by raymorris · · Score: 1

    I get how the general theory is supposed to work. Also, this idea has me thinking:

    We know that radio waves or other electromagnetic waves bounce off surfaces, in a way that an antenna can only barely detect the general direction of a large object. Can a device makes sense of refected electromagnetic waves in order to see high resolution detail? Well, ever heard of a camera - or eyes? Visible light is electromagnetic waves just like radio, only at a different frequency. So in theory there's no reason this wouldn't work THEORETICALLY.

    The walls are transparent to the wavelengths involved. Cameras can see through transparent things. So you just need a camera responds to those wavelengths. Infrared cameras are common.

    Cameras consist of basically two parts - a large number of light-sensing pixels, and a lens to focus that blurry reflection. Interesting thing is, none of the devices I've heard about have more than one or a few recieve - pixels. You'd expect high resolution would need a bunch of little sensors. I also haven't seen a focusing device serving the same purpose as a lens. Interesting that they are all building a camera that doesn't have either of the two main parts which make up a camera.

    Also it seems to me that if this idea really works, using basically Wi-Fi parts, and it has been developed to the point of sensing the tiny motion of breathing, I'm surprised some tinkerer hasn't made a really crude model from a couple of old wireless cards or routers. Something that can detect that big pipe full of water that's inside the wall, behind just one layer of drywall. If the concept works, that's should be a super simple, cheap implementation of the idea. Anyone done that yet? Not that I've seen.

    Nothing to see here.

    This definitely isn't totalitarian technology. It certainly won't be used by the police-state government we don't have to ramp up the panopticon we don't already live in just a little bit further.

    I'm sure the Stasi, the Gestapo, Big Brother Google, and the Department of War have no interest whatsoever in this technology. There's zero chance it will be used for evil. It's totally not true that this tech will be irresistible to a repressive government like we don't have.

    In summary, there's nothing to worry about. Move along now.

    This is a surveillance nightmare, and researchers should account for that in their work. This 'fundamental science is neutral' stuff often hinders having a good debate. Every single time the positive things get a lot fanfare, while obvious angles of abuse don't.

    You seem to imply this is some kind of problem. I'd like the police to know the difference between the victims and the criminals when trying to resolve a hostage situation, even if there is a wall in the way. One thing taught in the Army is that concealment is not always cover, this just adds another dimension to that. I'd rather we figure out how this works before our adversaries do.

    but I think it would be great for sleep studies. The non-sleep I got on that crappy little cot, while I was wired up and had a rubber band around by belly, was in no way representative of a typical night's sleep. I would expect better, more accurate results with less invasive equipment, and this development sounds as though it would help. We might even gain the ability to do sleep studies in the patient's home, resulting in results both more representative of a typical night's sleep, and less disruptive.
