Where is the talk from?

Tweet doesn't link to a full talk or paper, neither conference nor speaker is named, method appears to be inspired by the science fiction in a Batman movie...

Is this even real at all?

Every Wi-Fi router, or only routers it's trained on, deployed into rooms it's been trained on with camera footage?

Seems 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).

I remember something similar from years ago but this is more recent: 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.

The model only works if the furniture or the room is not modified much.

However, it's scary to think the implications.

Could we have a camera pointed through a telescope aimed at a window, have a radio receiver outside the said window, and train a model to predict human movements inside a room?
