Researchers at Carnegie Mellon University have developed a groundbreaking technology that uses artificial intelligence to turn Wi-Fi routers into ""cameras"" capable of seeing people through walls.
By analyzing the phase and amplitude of Wi-Fi signals reflected off objects, including human bodies, the system reconstructs detailed 3D models of people’s movements.
This technique, known as DensePose, maps every pixel on the surface of the human body, allowing Wi-Fi data to be used to visualize a person’s pose.
The technology has multiple potential applications, such as enhancing home security systems or monitoring individuals, like the elderly, in their homes. It offers the benefit of non-invasive monitoring, as it doesn’t require cameras, and Wi-Fi signals can pass through walls, enabling detection in different rooms.
However, this innovation raises serious privacy concerns, as it could be misused for unauthorized surveillance, emphasizing the need for ethical guidelines and regulations.
