在虚拟环境下的装配仿真环境中，建立了具有听觉和视觉反馈的装配仿真环境，并评价了听觉和视觉反馈对装配仿真任务绩效的影响。该VE实验系统平台将基于约束的装配仿真、光学运动跟踪技术、实时3D声音生成技术等复杂技术结合在一个虚拟现实工作台和一个通用软件平台上。以一个洞中钉和一个Sener电子盒组装任务为任务案例，对16名被试进行了人因实验。从实验中收集了关于在虚拟装配环境(VAE)中利用听觉和视觉反馈的客观表现数据(即任务完成时间和人的表现错误率)和主观意见(即问卷)。结果表明，在VAE中引入听觉和/或视觉反馈确实提高了装配任务的绩效。他们还指出，综合反馈(听觉和视觉)比单独使用的任何一种反馈都能提供更好的装配任务表现。大多数参与者更喜欢综合反馈，而不是个人反馈(听觉或视觉)或没有反馈。参与者的评论表明，不现实或不适当的反馈对任务绩效有负面影响，很容易让他们感到沮丧。
This paper presents the creation of an assembly simulation environment with multisensory feedback (auditory and visual), and the evaluation of the effects of auditory and visual feedback on the task performance in the context of assembly simulation in a virtual environment (VE). This VE experimental system platform brings together complex technologies such as constraint-based assembly simulation, optical motion tracking technology, and real time 3D sound generation technology around a virtual reality workbench and a common software platform. A peg-in-a-hole and a Sener electronic box assembly task have been used as the task cases to conduct the human factor experiment, using sixteen participants. Both objective performance data (i.e., task completion time, TCT; and human performance error rate, HPER) and subjective opinions (i.e., questionnaires) on the utilization of auditory and visual feedback in a virtual assembly environment (VAE) have been gathered from the experiment. Results showed that the introduction of auditory and/or visual feedback into VAE did improve the assembly task performance. They also indicated that integrated feedback (auditory plus visual) offered better assembly task performance than either feedback used in isolation. Most participants preferred integrated feedback to either individual feedback (auditory or visual) or no feedback. The participants' comments demonstrated that nonrealistic or inappropriate feedback had a negative effect on the task performance, and easily made them frustrated.
