Assembly processes require now more than ever a systematic way to improve efficiency complying with increasing product demand. Several industrial scenarios have been using augmented reality (AR) to enhance environments with different types of information and influence the overall user satisfaction and performance. The purpose of this work is to evaluate three different AR-based methods that can be used to support users during the execution of assembly procedures. The AR methods evaluated are handheld mobile AR, indirect AR (showing the augmented scene on a monitor) and see-through head-mounted display. A user study was performed to assess performance, mental and physical workload, as well as acceptance of the aforementioned methods. Results from a thirty participants study did not reveal a best method in terms of performance and user preference, showing that all methods are adequate to support users. However, the study highlights the strengths and weaknesses of each method, which may lead to potential advantages in specific use cases.

装配过程现在比以往任何时候都更需要一种系统的方法来提高效率，以满足不断增长的产品需求。一些工业场景一直在使用增强现实 (AR) 来增强具有不同类型信息的环境并影响整体用户满意度和性能。这项工作的目的是评估三种不同的基于 AR 的方法，这些方法可用于在装配程序的执行过程中为用户提供支持。评估的 AR 方法是手持移动 AR、间接 AR（在监视器上显示增强场景）和透视头戴式显示器。进行了一项用户研究以评估性能、精神和身体工作量，以及对上述方法的接受程度。三十名参与者的研究结果并未揭示在性能和用户偏好方面的最佳方法，表明所有方法都足以支持用户。但是，该研究强调了每种方法的优缺点，这可能会在特定用例中产生潜在优势。
