Mobile In-Situ Pick-by-Vision: Order Picking Support using a Projector Helmet

Abstract

Order picking is one of the most complex and error-prone tasks that can be found in the industry. To support the workers, many order picking instruction systems have been proposed. A large number of systems focus on equipping the user with head-mounted displays or equipping the environment with projectors to support the workers. However combining the user-worn design dimension with in-situ projection has not been investigated in the area of order picking yet. With this paper, we aim to close this gap by introducing HelmetPickAR: a body-worn helmet using in-situ projection for supporting order picking. Through a user study with 16 participants we compare HelmetPickAR against a state-of-the-art Pick-by-Paper approach. The results reveal that HelmetPickAR leads to significantly less cognitive effort for the worker during order picking tasks. While no difference was found in errors and picking time, the placing time increases.
