Embodied interaction with spatially-aware displays allows users to explore virtual information spaces situated in the real world. However, users are only able to see a limited part of the information space through the rather small display window. Targets are thus often hidden. Optimizing the layout of the information space by considering navigation times to targets therefore becomes essential to increasing the efficiency of a user. We contribute a novel model for the embodied navigation of a-priori unknown information spaces with spatially-aware displays. The model is inspired by physiological aspects of the human body. We have empirically validated the model in a controlled experiment with 32 participants.
