Human motion sensor is one of the most important devices for motion detection. In recent years, it has attracted the attention of many experts and researchers. According to the system, this paper compares the output of the arbitrary rotation of the human motion sensor, the position of the singular point, and the change of the magnetic field, and displays the calculation results, which verifies the accuracy of the output of the position calculation algorithm. With the development of MEMS technology, the advantages of human motion sensors brought by MEMS devices become more and more obvious. Dance cheerleading has developed rapidly in recent years and has spread all over the world. With the continuous improvement of the level of dance cheerleading competition, China’s physical requirements for cheerleading athletes are also constantly improving, and the athletes’ sports quality can be called the soul of dance cheerleading. In this paper, the relationship between structural simulation parameters and macro parameters of granular rock mass in plain area is studied. Through the numerical modeling of macro response of various models, the influence of contact stiffness, adhesion strength, friction coefficient, void coefficient, stiffness coefficient, and viscosity coefficient is analyzed, and the contact stiffness, adhesion strength, friction coefficient, and viscosity coefficient are calibrated. Viscosity index and other parameters related to water and sediment two-phase flow of granular rock mass structure in plain area. Through the establishment of a comprehensive evaluation standard, the development level of the whole athlete can be comprehensively evaluated. This paper focuses on the slow human motion sensor used in the detection of human motion.
