On the Computation of User Placements for Virtual Formation Adjustments during Group Navigation

Several group navigation techniques enable a single navigator to control travel for all group members simultaneously in social virtual reality. A key aspect of this process is the ability to rearrange the group into a new formation to facilitate the joint observation of the scene or to avoid obstacles on the way. However, the question of how users should be distributed within the new formation to create an intuitive transition that minimizes disruptions of ongoing social activities is currently not explored. In this paper, we begin to close this gap by introducing four user placement strategies based on mathematical considerations, discussing their benefits and drawbacks, and sketching further novel ideas to approach this topic from different angles in future work. Our work, therefore, contributes to the overarching goal of making group interactions in social virtual reality more intuitive and comfortable for the involved users.
