Over the past years, a variety of Augmented Reality (AR)-based applications were created, to support industrial processes. Although these first demonstrator applications or prototypes cover all parts of the industrial product process (design, planning and production, service and maintenance), only a few of them actually turned into established and applied solutions. In the automotive industry, one successful field for AR-based applications is factory design and planning. metaio and Volkswagen Group Research have concerted their research work to continuously enhance a first prototype in order to create a serviceable and accepted software tool, which is tailored to the needs of AR-based factory planning processes. This paper presents the developing process of this application, the requirements analysis and the realization as a complete system. A concrete example in industry describes the usage of the system for factory planning and an outlook on future work in this area closes the document.

Augmented Reality (AR) uses computer-generated virtual information to enhance the user's information access. While numerous previous studies have demonstrated the large potential of AR to improve industrial processes by enhancing product quality and reducing production times it is still unclear if and how long term usage of such AR technology produces stress and strain. This paper presents an approach to use the analysis of Heart Rate Variability to objectively measure current user strain during different work tasks. Results of a user study comparing strain during an AR supported and a non-AR supported work task in a laboratory setting are presented and discussed.

Optical see-through devices enable observers to see additional information embedded in real environments. There is already some evidence of increasing visual load in respective systems. We investigated visual performance when users performed visual search tasks or dual tasks only on the optical see-through device, only on a computer screen, or switching between both. In spite of having controlled for basic differences between both devices, switching between the presentation devices produced costs in visual performance. The assumption that these decreases in performance are partly due to differences localizing the presented objects was confirmed by convergence data
