Worker guidance systems are digital assistance systems in production, which provide work-related information and, thus, guide employees through production processes. This article describes the user-centered development of such a worker guidance system for a flexible production line in a metrology company. Usage context analysis and requirements analysis illustrate the need for a simple and independent system that can be used voluntarily by employees. After two iterations of the human-centered design process, an interactive software prototype was created and implemented on a tablet personal computer. In this prototype, all essential process and assembly information in the flexible production line is available to the employees in the form of text descriptions and pictures as step-by-step instructions, which can be selected via two-step navigation. The final evaluation was conducted as a user study with N = 10 assembly workers in the flexible production line under realistic conditions and was also intended to find out at which level of detail the information should be displayed in the system. The system scored well on the system usability scale (between 65.8 and 70.8) and concerning acceptance. Using the worker guidance system, no assembly faults occurred during the user study. Due to the significantly shorter assembly time, but no further significant differences, it was decided to set up the less detailed assembly information as a standard in the system. However, employees can call up more detailed information, if necessary. This system will be used by the company in the future.

以用户为中心的柔性生产线工人引导系统开发

工人指导系统是生产中的数字辅助系统，它提供与工作相关的信息，从而指导员工完成生产过程。本文介绍了以用户为中心，为某计量公司的柔性生产线开发这种工人引导系统。使用上下文分析和需求分析说明了对可由员工自愿使用的简单独立系统的需求。经过两次以人为本的设计过程迭代后，在平板个人电脑上创建并实现了交互式软件原型。在这个原型中，员工可以通过文本描述和图片的形式获得柔性生产线中所有必要的过程和装配信息作为分步说明，可以通过两步导航进行选择。N  = 10 名装配工人在现实条件下的柔性生产线上，还旨在找出信息应在系统中显示的详细程度。该系统在系统可用性量表（65.8 到 70.8 之间）和接受度方面得分很高。使用工人指导系统，在用户研究期间没有发生装配故障。由于装配时间明显缩短，但没有进一步的显着差异，因此决定将不太详细的装配信息设置为系统中的标准。但是，如有必要，员工可以调用更详细的信息。该系统将来会被公司使用。
