摘　　要：增强现实徒手虚拟装配可以让操作者以一种低成本、低认知偏差的方式训练机械装配技能。由于徒手交互缺乏触觉反馈且机械部件往往包含大量细小零件,造成真实的手部难以以一种自然的方式在虚拟空间内装配细小零件。针对以上问题,本文提出一个基于有限状态机的视觉反馈模型,该模型以徒手虚拟装配交互为基础,对装配细小零件过程中可能出现的各种操作状态都能做出视觉反馈,可有效提高增强现实徒手虚拟装配应用体验。最后,设计了一个应用案例验证理论的可行性。Bared-hand virtual assembly in augmented reality environment allows the operators to train mechanical assembly skills in a low-cost and low-cognitive way.Due to the lack of tactile feedback for bared-hand interaction and mechanical components often contain a large number of small parts,it is difficult for real hand to assemble small parts in the virtual space in a natural way.In re⁃sponse to the above problems,this paper proposes a visual feedback model based on a finite state machine.The model is implemented based on bared-hand virtual assembly interaction.The model can provide visual feedback on various operating states that may occur in the process of assembling small parts,which can effectively improve interaction experience.Finally,an application case is designed to verify the theory above.
