Title: Human navigation as path-planning in belief-space
Abstract: Goal-directed navigation requires continuously integrating uncertain self-motion
and landmark cues into an internal sense of location and direction, concurrently planning
future paths, and sequentially executing motor actions. We provide a unified account of
these processes with a computational model of probabilistic path planning in the framework
of optimal feedback control under uncertainty. This model gives rise to diverse human
navigational strategies previously believed to be distinct behaviors and predicts
quantitatively both the errors and the variability of navigation across numerous
experiments. This furthermore explains how sequential egocentric landmark observations
form an uncertain allocentric cognitive map, how this internal map is used both in route
planning and during execution of movements, and reconciles seemingly contradictory results
about cue-integration behavior in navigation. Finally, we show, how moment to moment
interactions of sensory, cognitive, and action uncertainty give rise to gaze behavior
shifting from active learning to active sensing. Taken together, the present work provides
a parsimonious explanation of how patterns of human goal-directed sensorimotor navigation
behavior arise from the continuous and dynamic interactions of spatial uncertainties in
perception, cognition, and action.
