Wearable inertial somatosensory table tennis training system and its working method

Abstract

A wearable inertial somatosensory ping-pong training system and a working method thereof, utilize an action acquisition module to collect motion data of a human body; use an action prediction module to train an action prediction model, and input the motion data collected by the action acquisition module into the trained action prediction model The corresponding action prediction results are generated in the system; the action evaluation model is trained by the action recognition evaluation module, and the action evaluation results are made according to the motion data collected by the action acquisition module; the table tennis trajectory model is established by the table tennis trajectory prediction module; The output of the prediction module, the action recognition evaluation module and the table tennis trajectory prediction module is converted into a visual image, and the virtual character is controlled to follow the user to make corresponding actions and the virtual table tennis is controlled to move according to the calculated space coordinates, and the user is also given. Action evaluation, improve the interactivity of the motion somatosensory process and the experience of the game.

Description

technical field [0001] The invention belongs to the technical field of somatosensory interaction systems and computers, and relates to a wearable inertial somatosensory table tennis training system and a working method thereof. Background technique [0002] With the progress of human society's spiritual civilization and the rapid development of material civilization, people's way of life has undergone earth-shaking changes, but while enjoying an efficient and convenient life, they also face serious personal health problems. The lack of physical activity in modern people is one of the important reasons for affecting health. Using effective methods to exercise to promote physical health will become an important part of modern life. [0003] Table tennis has a wide range of strengths and is highly skilled and interesting. It is suitable for all ages and many fans. However, it is also because of the great flexibility and high skill of table tennis that it is difficult for ordin...

AI Technical Summary

Problems solved by technology

[0004] Due to the complexity of table tennis, there are many defects in the existing table tennis action recognition and evaluation system, such as: the current complex motion capture system for the whole body needs to be equipped with wearable nodes all over the body, and the user experience is poor. The data will also affect the recognition speed; the table tennis movement is fast and the frequency is high, and it is prone to delay in the movement recognition, so the real-time, coherence and accuracy are poor, and it is difficult to effectively extract continuous dynamic data; the table tennis movement belongs to the whole body The current table tennis training system lacks a corresponding action evaluation plan; affected by various factors, the force of the table tennis during the flight is complicated, and the flight trajectory is complicated and difficult to predict. It is necessary to design a high-precision table tennis Motion Trajectory Model
