A Human Geometry Measurement Method Using IMU Sensor

In this paper, we propose a method for measuring the length of the arm span using a relationship between the linear velocity, the angular velocity of the circular motion of human. Using the measured characteristics of the proportional relationship between the arm span length and height, it is possible to estimate the height of the users. Also, we can decide the amplifier gain of the EMG sensors using the estimated height discrimination to differentiate with children and adults. In later, this method will be applied to the mass product MYO. This method will distinguish between adult and child in application for child.
