Abstract
In this paper, we propose a support system for substrate manufacturing workers. This system provides operation instructions on and around a substrate with projection mapping. The purpose of this system is to enable workers to produce substrates faster and more precisely in a product line which many kinds of substrates are produced. The examples of projected instructions are kinds of parts, number of parts and positions to insert parts. The projected instructions from our system change with time. Workers are required to produce a substrate by following the changing instructions. This process is expected to provide easy and rhythmical instructions for achieving faster and more precise manufacturing. To evaluate our system, we have applied the system for six months under actual product circumstance in the factory. The results show that our system reduces 12% of production time without producing reject products. We believe that this is a valuable study case that shows the effects of superimposed information in an actual product line on a long term basis.
