MIT programmer creates a safety device to help bikers convey their emotions while on the go.

A researcher at MIT has developed a bike helmet that is able to read cyclists’ minds. Arlene Ducao created the MindRider by embedding a bicycle helmet with EEG sensors and LED lights. When the helmet glows green, it means the cyclist has low stress levels, while red indicates high stress, and flashing red lights means that the wearer is in a state of panic.

Ducao has previously designed similar helmets that are manually operated, but soon realized that a hands-free device would be more practical. The MindRider uses a NeuroSky MindSet and can pick up ten types of brainwaves that show emotions such as fear, anxiety, and concentration.
