User-centered development of a system to support assembly line worker

This industrial perspective contribution describes the development of a prototype of a mobile worker assistance system to be used in the assembly line for motors that is changing to single piece flow. A large variety of user-centered methods were chosen to cover all phases of the development. Users were included in the analysis and evaluation phases. The results show that the methods are suitable for this type of development. Extended tests with users indicate that the prototype was very acceptable, especially for people with less experience on the assembly line. Since the system was tested in a real environment for five days with a number of users, the company now feels confident investing in the development of the system.
