Zero Touch
Human presence detection through walls, $4 chip, no camera
Zero Touch is two open-source research projects — PRISM and AURA — that detect and track humans using radio waves and electric fields instead of cameras. PRISM uses a single $4 ESP32 to localize people across room zones through walls using Wi-Fi CSI signals. AURA controls your cursor by hovering your hand over a capacitive sensor — no contact needed. Both run real-time ML inference on commodity hardware.
