以提高沉浸式虚拟3D场景的用户体验感为目的，在VR设备的支持下，从硬件和软件两个方面优化设计沉浸式虚拟3D体感交互系统.设计了加设头戴显示器和手持控制器两种类型的VR设备，改装了交互数据处理器和存储器，通过硬件软件的连接实现了系统硬件部分的优化；通过实体布设和光效生成两个步骤，构建沉浸式虚拟3D体感交互场景，利用VR设备获取实时体感数据，并根据体感数据的特征识别出沉浸式虚拟3D体感交互姿态；基于用户实时位姿和实体位置，检测出了虚拟3D场景中的碰撞行为，进而实现了视角切换、指令响应、漫游等体感交互功能.通过系统测试实验得出：与传统交互系统相比，优化设计系统输出交互界面分辨率明显提升，同时交互时延和交互偏差有所降低，即优化设计系统具有更高的交互功能.

With the aim of improving the user experience of immersive virtual 3D scenes, this study optimizes the design of an immersive virtual 3D sensory interaction system based on VR devices from both hardware and software aspects. Two types of VR devices, head-mounted displays and handheld controllers, are added to the system. The interaction data processor and memory are modified, and hardware optimization is achieved through the connection of hardware components. By conducting physical layout and light effect generation, immersive virtual 3D sensory interaction scenes are constructed. Real-time sensory data is obtained using VR devices, and immersive virtual 3D sensory interaction gestures are identified based on the characteristics of sensory data. Collision behaviors in the virtual 3D scenes are detected based on real-time user poses and physical positions, thereby realizing sensory interaction functions such as perspective switching, command response, and roaming. Through system testing experiments, it is found that compared to traditional interaction systems, the optimized design system significantly improves the output resolution of the interaction interface, while reducing interaction delay and deviation. Thus, the optimized design system exhibits higher interaction functionality.
