The interplay of pedestrian navigation, wayfinding devices, and environmental features in indoor settings

The focus of this study is on wayfinding in large complex buildings with different wayfinding devices. The interaction of pedestrians of such devices is always also interplay with the surrounding environment and its specific features. Furthermore different wayfinding assistances can elicit different needs for additional information from the environment to make accurate choices at decision points. We aim to shed light on how characteristics of decision points in combination with different wayfinding devices shape wayfinders' visual attention. 60 participants individually looked for three destinations in the same order. They navigated with 1) a printed map, 2) a digital map, or 3) without a map, only using full-coverage numeric signage. To gain first insights fixation frequencies on maps and signage as well as the correct and incorrect route options were recorded with a mobile eyetracker and analyzed for 28 decision points and four decision point categories. The results indicated that starting points play a special role in planning the route ahead. Furthermore points that allow for a floor change lead to a higher attention and information search.
