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.

Abstract: A gaming headset adapted for precise delivery of chemical substances capable of olfactory stimulation, such as odorants, fragrances, pheromones, etc. The headset includes at least one earpiece containing a speaker, a feature for securing the earpiece to the person's head while positioning the speaker over one of the person's ears when the headset is worn, an armature disposed relative to the earpiece so as to extend toward the person's mouth, a microphone located on the armature so as to be located in front of the person's mouth, and a feature supported by and extending along the armature for delivering at least one chemical substance to the person's nostril's when the headset is worn.
