Abstract

An interactive computer system responsive to a user'"'"'s voluntary and autonomic nervous system responses. The interactive computer system includes a computer, a voluntary input device requiring intentional actuation by the use, a sensor to detect autonomic nervous system responses, an interface device, and an output device. The voluntary input devices and output devices communicate with the computer. The sensors detect autonomic nervous system signals of a user and generate signals representative of the responses. The interface device communicates with the sensors and the computer. The interface device conditions the signals generated by the sensors and transmits the signals to the computer. The computer is responsive to the signals and produces an output command which is in part dependent upon the signals. The output device responds appropriately to the output command produced by the computer.
