尽管人们对增强现实（AR）在制造业应用中的潜力有很大的猜测，但很少有实证研究评估该技术的有效性。本章描述了一个测试AR指令在计算机辅助装配中的相对有效性的实验。AR解决方案将任务信息显示在用户的视野（FOV）中，作为与工作空间配准的3D对象。演示文稿演示了程序步骤的准确执行。三种传统的教学媒体方法与AR系统进行了比较：印刷手册，使用基于监视器的显示器的计算机辅助教学（CAI），以及利用头戴式显示器（HMD）的CAI。结果表明，在实际工件上叠加3D指令可以将装配任务的错误率降低82%，特别是减少累积错误，即由于以前的装配错误而导致的错误。心理努力的测量表明，在AR条件下的心理努力减少，这表明一些组装任务的心理计算被卸载到系统。结果表明，AR系统的计算机辅助装配可以提高工人的工作表现。
Although there has been great speculation about the potential of augmented reality (AR) in manufacturing applications, there have been very few empirical studies that assess the effectiveness of the technology. This chapter describes an experiment that tested the relative effectiveness of AR instructions in computer-assisted assembly. The AR solution displayed task information in the user’s field of view (FOV) as 3D objects registered with the workspace. The presentation demonstrates the exact execution of a procedural step. Three traditional instructional media approaches were compared with the AR system: a printed manual, computer-assisted instruction (CAI) using a monitor-based display, and CAI utilizing a head-mounted display (HMD). Results indicate that overlaying 3D instructions on the actual work pieces reduced the error rate for an assembly task by 82%, particularly diminishing cumulative errors, errors due to previous assembly mistakes. Measurement of the mental effort indicated decreased mental effort in the AR condition, suggesting some of the mental calculation of the assembly task is offloaded to the system. The results indicate that an AR system for computer-assisted assembly can improve worker performance.
