ABSTRACT
Abstract: Indoor navigation has proved to be complex to understand and to support with the use of external aids, be it signage, maps, or navigational devices. Research on the spatial cognition of complex indoor environments for the purpose of navigation is reviewed. The result of this analysis is an aggregated view of what makes indoor environments different from outdoor or transitional environments. The goal of this chapter is to coalesce the known cognitive principles to guide further research and tools in indoor wayfinding.
