Research News: Using WiFi RF Signals to Read Minds?

Researchers used WiFi signals to guess what people are thinking or saying, just like how a remote control knows when you press a button, even from across the room.

Imagine your WiFi router is like a super-sensitive listener. Every time you move, talk, or think, it sends out invisible waves called radio frequency (RF) signals. These waves bounce off you and go back to the router, kind of like how light bounces off a mirror.

By watching these bouncing signals closely, scientists can tell if someone is moving their head, opening their mouth, or even thinking about something specific.

Think of it like playing ping-pong. The ball (RF signal) goes to you, bounces back, and the person on the other side (the router) sees how it came back, they can guess where you hit it, or even what you're doing.

This clever trick helps scientists read minds, not with magic, but with a little help from your WiFi. Researchers used WiFi signals to guess what people are thinking or saying, just like how a remote control knows when you press a button, even from across the room.
