Abstract
The skill of orientating oneself in spatial environments is a fundamental human ability and a prerequisite to wayfinding. Wayfinding is the process of efficiently finding and following a route between a starting point and a destination. It relies on spatial information that has to be communicated to the user in order to solve this specific task. This can result in delivery of highly abstracted and sparse but efficient spatial information in terms of route descriptions or depictions. This information is typically generated from an information-rich environment. The abstraction process requires application of generalization to spatial descriptions and depictions. Generalization is needed for two tasks: in the selection of relevant wayfinding information and in the visualization of that information such that it can be immediately understood by the user. Since landmarks play an important role in wayfinding tasks, they have to be identified from the data set and then visualized appropriately. This leads to the identification of a class of objects that play an important role in wayfinding. Methods to characterize and automatically determine landmarks are presented followed by generalizing methods that can be used to communicate wayfinding descriptions. Finally, applications utilizing landmarks for navigation and wayfinding are described.
