This paper describes prototyping of a mixed reality (MR) order picking system which is used for a warehouse. Recently, MR, a technology that superimposes computer generated images (CGI) onto the real world in real-time, is used in various fields. MR technology has a variety of practical uses including assistance in machine maintenance and repair, parts assembly for industrial products, and so on. Especially, giving instructions to a worker using MR technology is used for wide range of applications. In this study, we try to make an MR based order picking system as one of the practical applications of MR technology. First, we analyze a conventional order picking system which employs colored lights mounted on racks for indicating picking items. Then, we design a prototype MR order picking system based on the result of the analysis. In our system, it is possible to provide intuitive information to the worker by displaying CGI such as an arrow through an HMD. We conducted experiments using both the conventional system and MR system to make a comparison of them and found some challenges for the future.
