An AR Tool to Support Warehouse Operations in the Context of Industry 4.0

Augmented Reality (AR) is one of the leading technologies of the Industry 4.0 revolution, offering innovative interfaces to promote the diffusion of digital contents into industrial processes, thanks to flexible and robust solutions and cost-effective devices. In this context, this paper explores the adoption of AR in industrial logistics where several open issues still discourage its effective use in everyday scenarios. After a review of objectives, approaches and technics of AR integration in logistics operations, the paper presents a framework to identify goods in a warehouse, retrieve data relative to the package, display info to the user to drive operations. The approach aims at easing and speeding up the activity of the warehouseman to identify goods, check the relative information and to put each good on the correct shelf. A prototypal application was developed within the Unity platform and integrated with the company ERP system to manage data on the products and retrieve images of the identification labels. A real use case involving a primary company producing agricultural tractors is proposed to test usability of the prototype. Results showed that the developed application allows relevant benefits in terms of process effectiveness, error prevention, aiming at reducing the operator mental workload.
