Augmented Reality (AR) applications gain more and more relevance in various industrial applications, e. g. for product presentations, education, engineering, etc. In the industrial domain, especially in process supervision applications, a number of standards and guidelines have been established to ensure that the design of user interfaces meets the safety requirements of plants or factories. Hence, we seek an evaluation if these guidelines can be applied to AR applications. In this paper, we present the first preliminary results of a case study on the application of those standards to a visual AR application for in-field inspection and servicing scenarios.
