随着公司不断创造越来越复杂的产品和提供越来越复杂的服务，在工作场所加强技术沟通和培训的需求变得越来越突出。在工厂车间，当技术人员由于信息不明确或缺乏说明而对程序的技术理解受到限制时，要成功地操作系统和组件尤其困难、昂贵且耗时。与当今使用的书面、视频和现场培训等传统培训方法相比，虚拟现实 (VR) 培训方法有可能使技术人员更有效地将其技能转移到现实世界。这项研究探索了 VR 训练技术，以节省时间、降低错误率并增强 VR 用户体验。 30 名参与者被随机分配到 VR 培训指导组，或没有使用书面指导和 2D 照片或视频指导进行 VR 培训的对照组。所有受试者都接受过组装 17 部分机械组件的培训。测量的具体目标标准是受试者花在学习说明上的时间、组装物理机械装配模型所花费的时间、物理模型中已解决和未解决的错误数量、参与者不按指定顺序执行装配步骤的次数以及用户对培训系统的偏好。调查结果表明，超过 85% 的参与者更喜欢 VR 提供的视觉 3D 演练说明，尤其是在组装过程更加复杂和复杂的情况下。结果表明，无论用户的学术背景或接触过 VR 的情况如何，他们都像其他培训方法一样轻松适应 VR 培训平台。结果表明，与未接受过 VR 培训的学生相比，接受过 VR 培训的学生在组装物理模型时没有时间损失，也没有准确性损失。
As companies continually create products and offer services of increasingly greater complexity, the need for enhanced technical communication and training is becoming more prominent in the workplace. On the factory floor, it is especially difficult, costly, and time-consuming for technicians to successfully operate on systems and assemblies when their technical understanding of a procedure is limited due to unclear information or a lack of instructions. Virtual reality (VR) training methodologies have the potential to enable technicians to transfer their skills into the real world more effectively than traditional training methods such as written, video, and live training used today. This research explores VR training techniques to increase time savings, reduce error rate, and enhance the VR user experience. A group of 30 participants were randomly assigned to either VR training instructions, or control groups without VR training using written instructions and 2D photos or video instructions. All subjects were trained to assemble a 17-part mechanical assembly. The specific target criteria measured were the amount of subjects' time spent learning from the instructions, their amount of time spent assembling the physical mechanical assembly model, the number of solved and unsolved errors committed in the physical model, the number of times the participant performed an assembly step out of indicated order, and the user preference towards the training systems. Survey results indicate that over 85% of the participants preferred the visual, 3D walk-through instructions offered with VR, especially if the assembly procedure was more complex and involved. Results show that users adapted to the VR training platform as easily as the other training methods regardless of their academic background or exposure to VR. Results suggest there was no loss in time nor accuracy for the VR trained students when assembling the physical model as compared to the non-VR trained students.
