Topological schemes for navigation from visual snapshots have been based on graphs of panoramic images and action links allowing the transition from one snapshot point to the next; see, for example, Cartwright and Collett[5] or Franz et al.[9]. These algorithms can only work if at each step a unique snapshot is recognized to which a motion decision is associated. Here, we present a population coding approach in which place is encoded by a population of overlapping “firing fields”, each of which is activated by the recognition of an unspecific “micro-snapshot” (i.e. feature), and associated to a subsequent action. Agent motion is then computed by a voting scheme over all activated snapshot-to-action associations. The algorithm was tested in a large virtual environment (Virtual Tübingen[24]) and shows biologically plausible navigational abilities.
