Maplets: Speculations on the Structure of Cognitive Maps


The cognitive representation  underlying human spatial navigation is often dichotomized into "route knowledge" and "survey knowledge." I will critique this traditional view. Motivated by concepts from studies of animal navigation, I will propose a different form of underlying representation for human navigation. "Maplets" are small pieces of maps whose configural information can be encoded from a single location using vision. I will discuss the maplet representation of building layouts, and an algorithm for combining maplets into a global cognitive map.
