Research on hybrid synchronization methods in multi-user collaborative VR simulation medical surgery training system

Abstract

The simulation training system based on VR technology has been applied in clinical medicine due to its immersive interactive experience, economy, and safety. In response to the limitation that most medical surgery training systems can only achieve single user operations, a hybrid synchronous model based multi-user collaborative framework design is proposed to meet the needs of collaborative training in virtual reality teaching processes. Based on the characteristics of frame synchronization and state synchronization, the synchronization method has been improved. Based on frame synchronization, specific state synchronization is used on interactive events to improve the consistency of operation details and real-time action. On this basis, a system prototype has been implemented using Unity 3D, and compared with traditional schemes, analysis shows that it has faster response speed for disconnected reconnection and more stable interaction state.
