A multimodal interaction system for navigation

To help users find their way in a virtual theatre we developed a navigation agent. In natural language dialogue the agent assists users looking for the location of an object or room, and it shows routes between locations. The speech-based dialogue system allows users to ask questions such as “Where is the coffee bar?” and “How do I get to the great hall?” The agent has a map and can mark locations and routes; users can click on locations and ask questions about them.
