Abstract: Several studies have verified that multi-level floors are an obstacle for indoor wayfinding (e.g., navigators show greater angular error when making inter-level pointing judgments and experience more disorientation when wayfinding between floors). Previous literature has also suggested that a multi-level cognitive map could be a set of vertically super-imposed 2D cognitive maps and each level could be viewed as a region. However, little research has studied how one mentally connects / integrates the different levels of the 3D cognitive map. This paper provides new insight into how people may integrate multi-level cognitive maps based on the concept of a “transition point”, a term used to represent the abstract point that connects different levels of the building. Based on transition points, we proposed the concept of simulated global indoor landmarks which are displayed on mobile devices. We predict that users can develop multi-level cognitive maps more efficiently when assisted by these global indoor landmarks. An ongoing behavioral experiment is briefly described aimed at providing empirical verification for these predictions.
