Abstract： |
A control method and a sense organ test method based on electrical steady state response of brain include the steps of producing one or more stimulate signals sensed by sense organs of human subject and varied at different frequencies: detecting the brain electrical signal of stimulated human subject; analyzing the detected brain electrical signal in which characteristic physical parameters in correspondence with a stimulate signal frequency is selected; based on this characteristic physical quantity, a controlled device in correspondence with the stimulate signal performs a prearranged operation or estimates objectively the sense condition of the subject. |
