AI can track human movement by utilizing only WiFi routers to "perceive" through walls. Yes, you read that correctly.

▶️ Three researchers employed three affordable consumer routers and receivers, without the use of LiDAR.
▶️ This development was carried out by Meta AI researchers with external assistance.
▶️ They utilized a system called "DensePose" to map around two dozen points and areas on human bodies.
▶️ By combining this data with a neural network, they successfully used WiFi signals to generate the images depicted below.

This breakthrough implies that WiFi can be employed to "see through" materials such as drywall, fences, concrete, and more.

Back in 2018, MIT employed similar technology to visualize people as stick figures through walls, but this is the first time such a level of detail, complete with wireframes, has been achieved.
