Free space 3D movement detect using gyroscopes and accelerometers

Abstract

Electronic inertial measurement components, which sense both acceleration and angular rate, are being used to detect motion of an object more frequently as their cost continues to drop dramatically. An Inertial Measurement Unit (IMU) will consist of two kinds of sensor, which are gyroscopes and accelerometers. Gyroscope is used to find out the orientation of an object and accelerometer is used to find out the displacement of an object. IMU is different from other motion detection technology such as infrared ray, which requires external signal to detect motion; as such kind of system is completely self-contained. ¡¥Self-contained¡¦ means that there is no need external information from outside world in order to accomplish the detection. In this project, an IMU will be intended to detect human motion.
