Collaborative Interaction Concepts for City Planning Tasks in Projection-Based Virtual Reality Systems

In this paper we propose solutions that allow several co-located city planners to perform domain-specific interaction tasks together in one semi-immersive projection-based VR system. After a registration process, e.g., by posing gestures or by using speech commands, this group activity can be performed either in a cooperative mode, i.e., tasks are accomplished consecutively, or in a collaborative interaction mode, i.e., users collaborate simultaneously. Both modes as well as multimodal concepts for the registration process are discussed and evaluated. Further VR-based interaction strategies for the city planning domain are presented, which are adapted to the demands of city planners working together in a shared virtual environment.
