Description
The cognitive map is the body of knowledge a human or robot has about
its large-scale spatial environment. We have developed a computational
theory of the human and robotic cognitive map [Kuipers, 1978, 1982; Kuipers
and Levitt, 1988; Kuipers and Byun, 1988, 1991]. Our theory of the cognitive
map is motivated by observations of human spatial reasoning skills and
the characteristic stages of child development [Lynch, 1960; Piaget &
Inhelder, 1967; Hart & Moore, 1973]. These studies provide two fundamental
insights. First, that a topological description of the environment is
central to the cognitive map, and is logically prior to the metrical description.
Second, that the spatial representation is grounded in the sensorimotor
interaction between the agent and the environment. Our theory of the cognitive
map is based on a hierarchy of representations for spatial knowledge that
we call the Spatial Semantic Hierarchy (SSH).
