Similar capability is scheduled for new consumer routers in 2024 via Wi-Fi 7 Sensing / IEEE 802.11bf. Hundreds of previous papers include terms like these:
human-to-human interaction recognition
device-free human activity recognition
occupant activity recognition in smart offices
emotion sensing via wireless channel data
CSI learning for gait biometric sensing
sleep monitoring from afar
human breath status via commodity wifi
device-free crowd sensing
