This book constitutes the refereed proceedings of the International Conference on Spatial Cognition, Spatial Cognition 2006. It covers spatial reasoning, human-robot interaction, visuo-spatial reasoning and spatial dynamics, spatial concepts, human memory, mental reasoning and assistance, spatial concepts, human memory and mental reasoning, navigation, wayfinding and route instructions as well as linguistic and social issues in spatial knowledge processing.
