The RF-Capture device sends wireless signals and reconstructs the human body by analysing reflections of those signals. It can be used to recognise a person or determine how a person is moving on the other side of a wall. It can also decipher handwriting in the air from behind a barrier.
The new device comes on the heels of some of MIT's previous technology, according to Gizmodo, in which researchers used radio frequency to detect motion behind a wall.
The RF-Capture doesn't require any additional devices or sensors to function. It is said to have a 90% accuracy rate. — AFP Relaxnews
