The Neural Impulse Actuator (NIA) is a brain–computer interface (BCI) device developed by OCZ Technology.
The name Neural Impulse Actuator implies that the signals originate from some neuronal activity; however, what is actually captured is a mixture of muscle, skin and nerve activity including sympathetic and parasympathetic components that have to be summarized as biopotentials rather than pure neural signals.
Individual signals that are isolated comprise alpha and beta brain waves, electromyograms and electro oculograms.
Control over the computer in either desktop or gaming environments is done by binding keys to different zones within as many as three vertical joysticks.
Moreover, the same "vertical joysticks" can be used in more than one instance to enable simultaneous pressing of multiple keys at any given time like "W" and "Spacebar" for jumping forward or toggling between left and right strafing for running in a zigzag pattern.
