Motion Classification and Features Recognition of a Traditional Chinese Sport (Baduanjin) Using Sampled-Based Methods

Abstract: This study recognized the motions and assessed the motion accuracy of a traditional Chinese sport (Baduanjin), using the data from the inertial sensor measurement system (IMU) and sampled-based methods. Fifty-three participants were recruited in two batches to participate in the study. Motion data of participants practicing Baduanjin were captured by IMU. By extracting features from motion data and benchmarking with the teacher’s assessment of motion accuracy, this study verifies the effectiveness of assessmen… Show more

“…These indicators will be affected by many factors, such as target gender, living conditions, age and physical exercise. [ 27 ] Our research results show that compared with the control group, the weight and BMI of female students in the Qigong Baduanjin group decreased significantly, which indicates that 12 weeks of Baduanjin exercise can significantly reduce the weight and BMI of female students. A previous study by Liu T et al also supports this result.…”

“…The Baduanjin motions of the volunteers were captured with the commercial IMU "Perception Neuron 2.0", developed by Noitom [18]. Perception Neuron 2.0 has 17 inertial sensing units with a 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer [19]. Sers et al verified the effectiveness the commercial IMU in measuring accuracy [20].…”
