Design and Research of Multiuser and Multimodal Virtual Fitness Equipment Based on VR

To address the issues of insufficient interactivity, scarce scenarios, and limited fitness types in traditional spinning bikes, this paper proposes a multiuser and Multimodal virtual fitness system. Through Multimodal interactions such as cycling and rowing, as well as multiuser online interactive technology, the user experience is significantly enhanced. The system hardware employs an Arduino development board to collect multi - source sensor data including heart rate, blood oxygen, and speed, and utilizes a Bluetooth module for wireless data transmission. The software is developed based on the Unity 3D engine, and Mirror is used to achieve multiuser and Multimodal network - based interactive functions. The design of this system enriches the types of fitness available to users, enables multiuser virtual fitness across different locations, and provides a novel solution for indoor fitness.
