The presentation modes available in Vitra Guide are natural language, maps and perspective views. Depending on situation-specific constraints, e.g., fully specifed route descriptions for pre-trip planning or incremental route descriptions during driving, Vitra Guide allows the coordinated distribution of the route information over the available presentation modes. The coordinated use of the presentation modes is achieved by a plan-based approach. The output for all presentation modes relies on one common 3-dimensional geometric model of the domain.enconference paper
