Where Do They Go? Overhearing Conversing Pedestrian Groups during Scene Exploration

On entering an unknown immersive virtual environment, a user's first task is gaining knowledge about the respective scene, termed scene exploration. While many techniques for aided scene exploration exist, such as virtual guides, or maps, unaided wayfinding through pedestrians-as-cues is still in its infancy. We contribute to this research by indirectly guiding users through pedestrian groups conversing about their target location. A user who overhears the conversation without being a direct addressee can consciously decide whether to follow the group to reach an unseen point of interest. We outline our approach and give insights into the results of a first feasibility study in which we compared our new approach to non-talkative groups and groups conversing about random topics.
