“It has traditionally been very difficult to capture such minute motions that occur at the rate of mere millimeters per second,” says MIT professor of electrical engineering and computer science Dina Katabi, the paper's co-author who also directs the Wireless Center. “Being able to do so with a low-cost, accessible technology opens up the possibilities for people to be able to track their vital signs on their own.”
"Katabi’s team is now working on higher resolution capabilities that would allow them to detect actual body silhouettes, gestures, and even emotions. (Heart rate and breathing are strong indicators of emotional extremes like fear or anger.)"
