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.

    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.
