摘要： A control-signal input device for computer game machines for generating game control signals based on the analysis results of biological signals, such as brain waves, in which a biological signal extracted by a biological-signal extracting means is analyzed. Signal components of each of a plurality of frequency components in the biological signal are obtained based on the above analysis results. The state of the biological signal is obtained by subjecting the signal components of each of the frequency components to a predetermined processing. A predetermined game control signal is generated in accordance with the state of the biological signal, and transmitted to a game machine via a changeover device.
