TL;DR
RuView is an open-source project that utilizes multiple ESP32 nodes to implement a technique known as "WiFi DensePose." This system transforms WiFi signals into real-time human pose estimation, presence detection, and vital sign monitoring—like breathing and heart rates—without the need for cameras. The implementation is done using Rust or Python, and it operates by analyzing Channel State Information (CSI) disturbances caused by human movement, allowing it to track body movement even through walls.
