Perceptual illusions based on the spatial correspondence between objects and displayed images have been pursued by artists and scientists since the 15th century, mastering optics to create crucial techniques as the linear perspective and devices as the Magic Lantern. Contemporary video projection mapping inherits and further extends this drive to produce perceptual illusions in space by incorporating the required real time capabilities for dynamically superposing the imaginary onto physical objects under fluid real world conditions. A critical milestone has been reached in the creation of the technical possibilities for all encompassing, untethered synthetic reality experiences available to the plain senses, where every surface may act as a screen and the relation to everyday objects is open to alterations.

We test the usefulness of Virtual Subjectiveness (Parés and Parés, 2006) as an analytical model for AMVR projects by means of the evaluation of the Bergen-Belsen VR/AR application. This application allows users to retrieve geolocated historical data through 3D architectural reconstructions, while exploring the site of the former concentration camp. Having analyzed the context of development of this application, its interface, mappings and interaction behaviors, and their interrelation in time, we found the Virtual Subjectiveness model to be an adequate paradigm to make a structured evaluation of the technical and conceptual levels of the chosen VR/AR application.
