In this talk, I will present selected research efforts from the Spatial HCI Lab which is part of the Geoinformation group at TU Wien. The spectrum of work ranges from exploring geo-data on public displays to geographic-aware augmented reality and automated recognition of states of spatial cognition during way finding. The talk will have two foci: I will, first, elaborate on the GeoAR framework allows us to display geo-referenced objects at their corresponding geo – coordinates, regardless of a user‘s position. This has a wide range of implications in terms of perception and augmented interaction possibilities. My second thread of the presentation will deal with work on recognizing processes and states of spatial cognition during human way finding in outdoor environments. I will provide evidence that it is possible to classify spatial cognition based on eye movements and/or head movements with very high accuracy. From an applicational perspective, this is a major step towards personalization of navigation assistance.
