The present invention relates to a gravity recognition function evaluation device based on virtual/augmented reality and multiple biosignal sensors, comprising: a head-wearable display device that is worn on a subject's head and reproduces an examination screen in which a target object is displayed in the center of the screen; After inferring the subject's posture value using a gaze tracker that senses the subject's pupil size and a plurality of inertial measurement sensors distributed over the subject's body, a position control value corresponding to the subject's posture value is obtained and a biosignal measuring device including a posture measuring device for outputting; a human interface device for obtaining and outputting a position control value manually input by the subject; and after generating and providing the inspection screen, a position control value obtained through any one of the posture measuring device and the human interface is compared and analyzed with a preset target position value to obtain and provide a gravity recognition error value, and at the same time A control device for additionally acquiring and providing a cognitive power requirement based on the pupil size of the subject, wherein the biosignal measuring device measures the brain nervous system response of the subject, and adds individual cognitive power demand and changes in the brain nervous system according to the test mode It further includes an EEG that calculates.
