"OCZ has announced mass production of their highly anticipated Brain Control Interface demoed at CeBIT 2007. The Neural Impulse Actuator, or NIA, interprets those letter erasing thought patterns into actual computer input commands. The BCI based device attaches to a triple electrode sweatband that sends amplified Alpha and Beta wave fluctuations emitted by the brain, and it monitors muscle use and eye position. It might be possible to save all those WASD keys like ours.
It is not that much different from a polygraph test. Instead of a reader interpreting sensor output from the skin to tell if a person is honest, the computer interprets the brain sensor output to determine if a command is required. Utilizing software, the NIA acts like a fully customizable joystick. Similar to "Game Controllers" under the windows control panel, users will be able to map specific biological feedback to a virtual button/axis on a controller. The virtual controller can then be mapped to commands in a game. Software implementations for GUI navigation and other desktop activities should follow soon.
