MIT researches can see through walls using RF signals
MIT researches are always on their toes working on breathtaking technologies that most of us don’t even think can ever exist. Case in point, RF-Capture – a device that captures human figures through walls with near perfect accuracy. Developed by scientists at MIT’s Computer Science and Artificial Intelligence Laboratory, the RF-Capture can transfer wireless signals to reconstruct a human figure and then analyze these signal reflections. Using the device, researchers claim, they can literally see through walls and identify which person is standing behind it and what the person is doing.
Basically, RF-Capture works by sending our radio waves through the wall. On hitting the person on the other side of the wall, the waves are reflected off through various parts of the individual’s body. The reflected signals are collected by the device for analysis.
Using a complex algorithm, the device puts various captured human figures together to form a silhouette model of the person.
Interestingly, the device cannot only identify a person’s body parts, it can also – distinguish between two different people behind the wall. Additionally, the device that touts to be 90 percent accurate can also figure out how a person is moving behind the wall or what the person is writing in the air on the other side of the wall.
