Modeling Gaze-Guided Narratives for Outdoor Tourism

Many outdoor spaces have hidden stories connected with them that can be used to enrich a tourist’s experience. These stories are often related to environmental features which are far from the user and far apart from each other. Therefore, they are difficult to explore by locomotion, but can be visually explored from a vantage point. Telling a story from a vantage point is challenging since the system must ensure that the user can identify the relevant features in the environment. Gaze-guided narratives are an interaction concept that helps in such situations by telling a story dynamically depending on the user’s current and previous gaze on a panorama. This chapter suggests a formal modeling approach for gaze-guided narratives, based on narrative mediation trees. The approach is illustrated with an example from the Swiss saga around ‘Wilhelm Tell’.
