Leveraging a tool called DensePose from Facebook AI lab, the system scans the invisible Wi Fi radio signals that permeate throughout a space and builds a visual model. Radio signals broadcast by a Wi Fi router naturally bounce off objects and people, and the reflected signals carry information that can be filtered through AI to reconstruct body posture and movements. Similar to how LiDAR or echolocation can be used to build a crude three dimensional representation of rooms or an area, DensePose...
