A new form of technology from the MIT Wireless Center has the potential to replace wearables. The motion monitoring system uses WiFi signals to track people's movement, breathing patterns and heart rate through walls and closed doors. In addition to the world of fitness, this technology could completely disrupt disaster relief, gaming, law enforcement and others.
The most recent work from the MIT Wireless Center's Computer Science and Artificial Intelligence Laboratory uses the power of x-ray vision in addition to low-strength WiFi signals. By measuring the signals' reflections, they can track movements. This will allow people to measure the vitals of their family members in a way that is both portable and accessible to the public.
