Abstract
A biosignal-computer-interface apparatus and method. The apparatus includes one or more devices for generating biosignals based on at least one physiological parameter of an individual, and a computer-interface device capable of performing multiple tasks, including converting the biosignals into at least one input signal, establishing a scale encompassing different levels of the input signal, multiplying the input signal into parallel control channels, dividing the scale into multiple zones for each of the parallel control channels, assigning computer commands to each individual zone of the multiple zones, and generating the computer command assigned to at least one of the individual zones if the level of the input signal is within the at least one individual zone. The individual zones can be the same or different among the parallel control channels.
