Abstract

An adaptive sport posture sensing system has a sensing device, a sensing signal acquiring unit and a sport posture processing unit. In the determination mode, the sport posture processing unit selects one piece among multiple established pieces of sport posture reference data according to a sport name, a wearing position and one piece of user body information, the sensing signal acquiring unit obtains at least one first sensing signal sensed by the sensing device, and the sport posture processing unit compares a sport posture data generated based upon the at least one first sensing signal with the selected piece of the sport posture reference data, so as to determine whether a sport posture of the user is correct or not.
