Research on physical human-computer interaction virtual reality fitness method combined with Unity3D technology

To respond to the slogan of the national fitness movement, improve the quality of the national fitness movement, and provide scientific reference to public fitness, this paper studies the fitness method of Unity3D technology and somatosensory human-computer interaction virtual reality technology. Firstly, we build a somatosensory HCI virtual fitness system with Unity3D and Kinect technology, verify the data with an edge detection operator, get the simulation results of the somatosensory HCI virtual reality fitness system, and then get the fitness method based on the somatosensory HCI virtual reality technology according to the results. The data show that the fitness industry is seeing new highs as the national fitness membership reaches 75.13 million people as of December 2021, while the growth of women among them increases from 13.5 million in 2017 to 55.6 million in 2021. Among the 800 fitness methods, the physical therapy and rehabilitation category accounts for 1/3, and fitness, bodybuilding and health care each account for about 1/5. The comfort zone of fitness differs between men and women, ranging from 0.6-1.2 for men and 0.5-0.9 for women. The research in this paper can provide reasonable fitness advice to the fitness population and promote the healthy development of the fitness industry. © 2023 Weihua Zhang, published by Sciendo.
