在增强现实（AR）装配中，由于装配指令信息内容表达不直观，信息形式设计不规范，导致用户装配效率低，操作错误率高。阐述并定义了一种面向用户的汇编指令分类方法。该方法根据用户对装配任务的认知需求对传统装配指令进行重新分类，提高用户对物理任务的认知效率。本文首先重申了传统装配指令的定义，说明了它与AR装配指令的几何关系。然后，给出了AR装配指令在信息级的定义，并根据此定义对传统装配指令进行了分类，并对每种分类做了说明。我们比较了新旧指令在典型组装用例中的作用。数据显示，新老指令在性能上存在显著差异。新指令在装配时间和操作体验（包括享受、专注、信心、自然直觉、可行性、有效性、可用性和可理解性）方面显著提高用户的表现，通过使用AR指令在信息层面和辅助重新分类，从而达到高效简洁的操作目的。此外，还讨论了本研究的意义和未来的研究方向。
In augmented reality (AR) assembly, due to the unintuitive expression of the information content of the assembly instructions and the irregular design of the information form, the user’s assembly efficiency is low and the operation error rate is high. This paper elaborates and defines a user-oriented classification method of assembly instructions. This method reclassifies traditional assembly instructions based on the user’s cognitive needs for assembly tasks to improve users’ cognitive efficiency of physical tasks. In this article, the definition of traditional assembly instructions is first reiterated, and the geometrical relationship between it and AR assembly instructions is explained. Then, the definition of AR assembly instructions at the information level is given, the traditional assembly instructions are classified according to this definition, and the explanation of each classification is made. We compared the role of the old and new instructions in typical assembly use cases. The data shows that there are significant differences in performance between the new and old instructions. The new instructions significantly improve the user’s performance in terms of assembly time and operating experience (including enjoyment, concentration, confidence, natural intuition, feasibility, effectiveness, usability, and understandability), through the use of AR instructions on the information level and auxiliary reclassification, so as to achieve efficient and concise operation purposes. In addition, we also discussed the significance of this research and future research directions.
