Summary
|
Natural and effective spatial communication requires the dynamic negotiation of spatial
reference frames, spatial perspectives and discourse strategies. Speakers manage such
negotiation by the fine-scale selection and alignment of linguistic forms sensitive to
dialogue history, user-group defined norms and spatial context. Necessary negotiation
mechanisms will be empirically derived, implemented within a dialogue system for natural
interaction between users and artificial agents engaged in spatially-embedded tasks, and
deployed in SFB/TR 8 projects for improved functionality and evaluation.
