Mixed reality has been proposed for industrial applications such as AR-assisted manteinance and repair in which real equipment are augmented by visual AIDS. A possible complementary use of this technology for the same context can be achieved by performing virtual training in a 'mixed reality environment' enabling to observe actual-size virtual replicas of real equipment within the physical space, providing an advantage in terms of perceptual impact and learning efficacy compared to traditional computer-based-training techniques. To this aim we present an effective hybrid tracking approach, exploiting both optical markers and inertial sensors to measure user's head position and rotation, providing both accuracy and robustness to fast head movements. A field-deployable tridimensionally-arranged marker-set, specifically designed for this kind of application, represents a further contribute of this paper, providing reliable close-to-medium distance optical tracking capabilities and increased robustness to challenging lighting conditions. First experiments confirm the potential of the proposed solution for this context and for many other applications as well.
