碩士 === 國立勤益科技大學 === 電子工程系 === 102 === In this paper, the sensing element is embedded in the billiard to detect static billiard's posture and position, and to access moving direction and acceleration during the hitting moment. Sensing elements are mainly accelerometer, gyroscope and magnetic sensor. The data of sensing element is read by a microcontroller Arduino-nano, and then wirelessly transmitted, via Bluetooth, to embedded system GPL-32500 for further processing. The read accelerometer’s data while the ball is static, is calculated with Euler angles equation to derive a sphere orientation. With this orientation and magnetic sensor's data, this billiard’s azimuth can be determined with some calculation. When the ball is hit, the ball's moving direction and force can be derived from calculation of triaxial acceleration data from the accelerometer and billiard’s static azimuth.
