OCZ Technology has laid claim to being the first company to bring a "brain-computer" interface to the retail market and they have aimed it squarely at the gamer. The device is called the NIA, which is an acronym that stands for Neural Impulse Actuator, and instead of buttons, sticks, gyroscopes or motion sensors, it reads the body's natural biosignals and translates them into commands that can be used to control PC games.
