MIT Researchers Can Take Your Pulse, Right Through the Walls
An anonymous reader writes MIT researchers develop technology that can monitor people's breathing and heart rate through walls. 'Their latest report demonstrates that they can now detect gestures as subtle as the rise and fall of a person's chest. From that, they can determine a person's heart rate with 99 percent accuracy. The research could be used for health-tracking apps, baby monitors, and for the military and law enforcement.' The report describes how they extended their through-wall technology to up to five users and how they track vital signs.
I'm pretty sure a baby can be monitored through a wall by using a window, but does it run on Linux?
Radar porn is inevitable.
Good, the doctors can take my vitals while waiting in the waiting-room to cut time.
Table-ized A.I.
... More like tinfoil skinsuit.
This will probably be a feature in new TV sets. Of course, all this data will be transmitted to advertisers.
(On the other hand, it would be great for gyms and for workout programs.)
Aluminum foil will nicely block the 5.46-7.25 GHz (4-5 cm) radio waves used for this radar (as would a typical screen door). I wonder who will be the first to market RF-opaque sheet-rock, which would technically easy to make.
those pesky photons are at it again
"The research could be used for health-tracking apps, baby monitors, and for the military and law enforcement."
Yeah, lead with the health-tracking and baby monitors, which actually benefits the subject, such that the subject would happily allow a monitor right next to them, and thus "through the walls" monitoring will never, ever get used.
Bury the bit about using it shoot people who break a drug law, or a resister of some foreign tyranny, in a way that they never have a chance to see it coming, which is how this will actually get used.
Ugh.
We know where leadership by an anti-intellectual "strongman" who scapegoats minorities and likes boisterous rallies goes
I have read the paper and thing that is noticeable for an academic paper is that there appears to be no acknowledgement of the source of funding, which leads me to wonder who is paying for this and why they want that link kept quiet.
Never forget the SWARTZ else you are condemned to repeat it.
need a warrant to search rooms , never entered?
walk down hall in hotel, see whose heart rate elevated.
spy on spouse remotely. Having an affair?
"No where to hide" . Criminals can use it too. See if place is empty before breaking and entering....
The kind that can stop a not too bright light source from illuminating the next room, aka drywall? Or a real one?
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
Depending on how well it can separate subjects, this could be quite useful in an airport for (non-descriminative) screening.
You've got one guy walking through whose heartrate is abnormally high, there's a decent change he's up to something inappropriate (smuggling, terrorism). The other possibility is that he has a fear of flying, but secondary screening should hopefully be able to determine that.
Even better, have an airport security person walk by him or just look him in the eye and smile, then see if his heart-rate goes up even more. Sudden jump in vitals... bingo!
The research could be used for health-tracking apps, baby monitors, and for the military and law enforcement.'
Of course, always for the military and law enforcement. The ethos of technology development in this country, spreading to the world, increasingly sickens me.
Anyone else reminded of Splinter Cell, where Sam can track people's "life signs" through his googles?
Yes, "law enforcement", who aren't at all obsessed with lots and lots of SWAT teams and just short or even outright military hardware to make war on the populace. Who obviously need more technology to spy on, er, keep us all safe by carefully tracking our every move. Yes that's it. No safety without observation. No freedom without safety. Spying on you for your freedom!
Good call, MIT.
It's the heartbeat sensor from Tom Clancy's Rainbow Six stories / games!
As a medic, I can tell you there is not a direct correlation between pulse and respiratory rate between different individuals. While pulse and respirations may generally be proportional in any one individual, there's no way they can accurately infer a pulse from knowing respiration rates, since what drives one heart to beat at 60 bpm, while he breaths at 12 rpm, might drive another to beat at 75 bpm, but respire at only 12. It all depends on the relative efficiencies of the cardiac muscle and lungs.
If this weren't so, medical persons would not be obliged when taking a patient's vital signs to record both pulse and respirations, (besides also blood pressure, temperature, etc.) but we are. The claim of 99% accuracy is what marks this story as bullshit so clearly. By the by, pulse and respirations vary within a single individual pretty wildly, from one minute to the next. So yeah... bullshit.
The disturbing part is the notion of walls and doors being about as transparent, light or dark, as your windows with the drapes pulled. Homes are increasingly becoming obsolete. Privacy is a vanishing thing. People say, "you gave up your privacy by living in society," but then again, what about those people who haven't chosen any such thing? People who've never owned a computer, and whose phones up to maybe 10 or 15 years ago had a big round thing on the front of them? People who still own cathode-ray tube television sets? People who've heard of e-mail but never sent one?
On the other hand, the notion of being able to see through walls using RF has been around for a while, so this really sounds like a bit of a non-story, or if there is a story, it's that the resolution has gotten better.
Maybe the real story is how someone wasted a bunch of grant money learning how better to peep and spy on people like little children. How sad. The money's wasted.
Make sure to buy the heartbeat sensor before deployment!
They had it right once again.
So now robot killing machines can check to see how agitated they've made you, right before they kill you. Nice.
Research in tracking heart rate and respiration using radio waves has been happening for decades. Technology has progressed to the point where modern devices can detect a heartbeat through 30 feet of rubble or 20 feet of solid concrete: http://www.dhs.gov/detecting-h... . Chapter 2 of Jonathan S Burnham's 2009 MIT master's thesis seems to have a nice historical overview: http://hdl.handle.net/1721.1/6... . There probably are novel things about the MIT technology mentioned in the original post (e.g. lower power RF or better separation of individuals), but there is nothing new about tracking heart rate and respiratory rate through walls.
Radar work performed in Italy can see the movement of the heart directly:

This is very old tech...like 1960's or '50s.
If only the people that will inevitably apply these new discoveries weren't the exact opposite.

Just use lead paint. :)
You realize there was no need to tell me that, don't you? I can tell you're breathing from way over here.
Defense. Always has been the biggest sponsor of MIT and CSAIL. Google for it. They sell their brainpower in order to kill people more efficiently.
It's called a "bat". As in the flying mammal.
What do you think this technology will be used for?
What does 'determine a person's heart rate with 99 percent accuracy' mean??? Does that mean a SE of 1% on the heart rate or just that 1% of the test subjects got wildly wrong readings?
TFA cites a report that measures the breath rate which says it is tracked within a rounding error of one breadth during all the experiment. But that report never mentions heart rate...
Too late MIT! VAWD out of Tucson AZ has been doing this for years now. No, I don't work there, but I have seen this tech in action and it's super cool.

working on the important and useful stuff
lulz. i like joke, but no has upvote button :(
...not before thousands of lives are ruined. Every one of those people will need the money and resources to appeal; many will wait years before they're finally released. Justice is eventually served, but only after many years and at a colossal human cost. There is undeniable evidence that the NSA and DEA are cooperating *right now*, yet people will continue to be raped, beaten, and tortured in federal prison for years as a result of their malicious and illegal actions.
The police and government are all too often allowed to do damage at will, and then settle for pennies on the dollar later when a competent judge and jury, years later, finally get to the truth.
I can definitely tell when she has an elevated heart rate, not to mention the timing of each thrust. No advanced technology required.
