Every Wi-Fi router, or only routers it's trained on, deployed into rooms it's been trained on with camera footage?
- teaearlgraycold 3y agoSeems like you'd need to know the geometry of the room in advanced (either by reconstructing it in software or training like they did with a camera).

This won't account for differences in furniture, but I'd imagine, over time, one could filter out and work around static objects. America's cheap-as-hell apartments could cause even more problems beyond giving apartments a bad rap!
- CommitSyn 3y agoI remember something similar from years ago but this is more recent: https://www.zmescience.com/feature-post/technology-articles/computer-science/wifi-router-sees-people-through-walls/ https://www.zmescience.com/feature-post/technology-articles/... > For their demonstration, the researchers used three $30 WiFi routers and three aligned receivers that bounce WiFI signals around the walls of a room. The system cancels out static objects and focuses on the signals reflected off moving objects, reconstructing the pose of a person in a radar-like image. This was shown to work even if there was a wall between the routers and the subjects.
