Method and apparatus of recognizing a motion using the rectangular coordinate system

摘要

The present invention relates to a motion recognition method, which comprises the steps of: obtaining an angular acceleration of a motion from a gyro sensor; obtaining the magnitude of the acceleration present on a plane perpendicular to the axis of rotation of the motion from the acceleration meter; calculating a rotation radius of the motion from the obtained angular acceleration and the magnitude of the acceleration; and determining the type of the motion by using the calculated rotation radius. The axis of rotation of the motion is characterized in that any one of the x-axis, y-axis, z-axis in the rectangular coordinate system. By obtaining the rotation radius from the sensor data and using the same for motion recognition, motions having similar sensor data can be more precisely distinguished.
