沉浸式虚拟训练中的虚拟手操控技术研究

将人手的自然动作加入沉浸式虚拟现实系统中,可有效提高系统的沉浸感和交互性,简便快捷、成本低廉的虚拟手建模及操控技术,有助于此项内容的推广应用；在对虚拟手骨骼结构模型分析的基础上,提出了基于Leap Motion的虚拟手控制方法和流程；以维修训练为任务背景,设计了四种用于虚拟手操作的手势规则,并对实现流程和关键技术进行了分析；构建基于Unity3D引擎的原型系统对虚拟手进行仿真验证,结果表明,基于Leap Motion的虚拟手操控简单、交互自然,可以满足虚拟现实系统交互需要。

Research on Virtual Hand Control and Operation in Immersive Virtual Training

To add the man''s hand movements to immersive virtual reality system can effectively improve the immersive and interactive system. Simple, fast, and low cost technology of virtual hand control and operation contribute to the application of virtual hand. Bone structure model of virtual hand is analyzed, and then control method and process of virtual hand based on Leap Motion is put forward. Taking maintenance training as background, four gesture rules of virtual hand operation are designed. RealizationSflowSand key technologies of virtual hand operation is analyzed. A prototype system based on Unity3D engine is constructed to verified virtual hand by simulation. The results show that the operation of virtual hand based on Leap Motion is simple, interaction is nature, which meet the needs of the virtual reality system interaction.
