MOTION DETECTION SYSTEM ON 6-INDUCTION POINTS IN HEAD PORTION USING HELMET HAVING NINE ACCELEROMETERS

摘要

PURPOSE: A motion detection system on 6-induction points in a head portion enables a long time detection by using a helmet having nine accelerometers considering a centrifugal force and a cross acceleration. CONSTITUTION: A motion detection system on 6-induction points in a head portion includes a helmet(6) which is worn on the head portion of a subject and 9 accelerometers(4) attached on an outer surface of the helmet for a detection of 6-induction points in the head portion. The motion detection system further includes two accelerometers on an X-axis and a Z-axis on point A and B, two accelerometers on the X-axis and an Y-axis on point C, two accelerometers on the Y-axis and the Z-axis on point D, and one accelerometer on the Y-axis on point E, where a motion detection point inside of the head of the subject is point O, a left position of the helmet is A, a right position is B, a front position is D, a rear position is E, and an upper position is C.
