Abstract

This research aims to use the commercial inertial measurement unit (IMU) motion capture (MoCap) to build a formative assessment system in Baduanjin physical education (PE) to assist PE teachers in completing the formative assessment. The system recognizes motions and assesses motion accuracy by analyzing the motion data captured from students with IMU MoCap. The Baduanjin motions dataset was obtained by recruiting students and teachers to verify the feasibility of the commercial IMU MoCap in recognizing motion accuracy. Furthermore, based on the dataset, suitable methods for recognizing motions and assessing the motion accuracy of Baduanjin were developed and verified. The formative assessment system in Baduanijn PE was built on selected methods and for objective users test. The system obtained excellent accuracy in recognizing student motions (99.77%), and there is a solid connection (over 0.8) between the system and the teacher for assessing motion accuracy. The objective user test demonstrates that the formative assessment system built on IMU MoCap is appropriate for the Baduanjin PE.
