To limit musculoskeletal disorders we are working towards implementing collaborative robotics in strenuous or repetitive production work. Our objective is to evaluate augmented reality (AR) devices for assisting in near-distance tasks before applying and testing the displays in the context of human-robot collaboration in a production setting. This chapter describes the hardware setup and procedure for testing AR systems for showing sub-surface positions of foreign elements in an opaque mass. The goal is it test four types of setup in terms of user accuracy and speed, the four setups being a head-mounted see-through display, a mounted tablet-based see-through display, top-down surface projection and overlays on a static monitor. The experiment is carried out using a tracked HTC Vive controller with a needle attachment. Precision tasks are performed by 48 participants and each display is evaluated using the System Usability Scale and the NASA Task Load Index.
