Study of the impact of projection-based assistance systems for improving the learning curve in assembly processes

摘要

With the introduction of Industry 4.0 the use of worker assistance systems is getting more and more important.Assistance systems should support operators to increase efficiency and to reduce physical and mental stress and thus increase ergonomics of the work.In this paper,we investigate the impact of a projection-based worker assistance system conducting lab experiments simulating a ramp-up situation of a new product in assembly.The specific aim is the investigation of the impact of such systems in assembly for improving the learning curve,when products are changing.The study shows the results of a comparison between the assembly process with traditional worker instructions and the use of cognitive assistance systems to project instructions on the workplace.
