NeuroSky Inc, a venture company based in San Jose, Calif, prototyped a system that reads brain waves with a sensor and uses them for mobile phone applications.
The company exhibited the system at CTIA Wireless IT & Entertainment 2008, an exhibition running from Sept 10 to 12, 2008, in San Francisco, Calif. The headset-shaped system consists of a sensor to read brain waves, digital signal processing part and so forth. The sensor contacts with a point on user's forehead.
By reading brain waves such as a and ß waves, the system can roughly measure the degrees of brain's relaxation and concentration, NeuroSky said. The data of brain waves can be displayed on the screen of a mobile phone by using a visualizer or can be used to control the movement of a video game character.
