【 摘 要 】

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