NeuroSky Demos Brain Waves Controlled
Application On The Nokia N95 8GB!

I've already written about the very science-fiction eye, and various diffrent touchless control interfaces for mobile phones but now it evolved into something more realistic, manageable and useful.

NeuroSky Inc, a venture company based in San Jose, Calif, prototyped a system that reads brain waves with a sensor and than uses them to control applications on the mobile phone.

The company exhibited this innovatoive 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 α and β 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 visualized or can be used to control the movement of a video game character.

A game in which a player moves a character, a ladybug in this case, to a destination. The higher the degree of brain's concentration, the faster the ladybug moves.
