In 2013, they showed off software that could use variations in wifi signal to<a href=\"http:\/\/gizmodo.com\/oh-great-wi-fi-networks-can-be-used-to-see-through-wal-609356785#_ga=1.180830567.1366711378.1442769390\"> detect the presence of human motion from the other side of a wall<\/a>. But in the last two years they\u2019ve been busy developing the technique, and now they\u2019ve unveiled the obvious \u2014 if slightly alarming \u2014 natural progression: they can use the wireless reflections bouncing off a human body to see the silhouette of a person standing behind a wall.<\/p>\n<p>Not only that, the team\u2019s technique, known is <a href=\"http:\/\/rfcapture.csail.mit.edu\/\" target=\"_blank\">RF-Capture<\/a>, is accurate enough to track the hand of a human and, with some repeated measurements, the system can even be trained to recognise different people based just on their wifi silhouette.
