Someday soon, video gamers may be able to use their heads, literally, to get better scores in their games. At least two start-ups have developed technology that monitors a player's brain waves and uses the signals to control the action in games. They hope it will enable game creators to immerse players in imaginary worlds that they can control with their thoughts instead of their hands.San Jose's NeuroSky has been testing prototypes of its system that uses a sensor-laden headband to monitor brain waves, and then uses the signals to control the interaction in video games. They hope that such games are just the beginning of a mind-machine interface with many different applications.``Research on brain waves is well known,'' said NeuroSky Chief Executive Stanley Yang. ``But we have worked on a way for detecting them with a low-cost technology and then interpreting what they mean. We think this will have broad applications.''Sensors in the head gear -- whether headbands, headsets or helmets -- measure electrical activity in the brain that scientists have studied for decades. Using NeuroSky's chip technology, the system can distinguish whether a person is calm, stressed, meditative or attentive and alert. Beyond games, the system might be useful for determining whether drivers are so drowsy that they need an alarm to awaken them.NeuroSky's chief technology officer and co-founder, Koo Hyoung Lee, is a South Korean scientist who for years studied how athletes concentrate. He formed NeuroSky in fall 2004. The company has raised seed money and is raising its first round of venture capital now.Lee's team of researchers figured out how to detect signals with simpler sensors than the devices used to monitor coma patients in hospitals. NeuroSky is selling the components for the monitoring as well as the software for interpreting the brain signals. Its customers and partners could include makers of game peripherals as well as developers who create games.
