Abstract
Abstract. Recent years have seen raising interests in mobile pedestrian navigation systems. Different interface technologies can be used to communicate/convey route directions to pedestrians, such as mobile maps, voices, and augmented reality (AR). Many field experiments have been conducted to study the effectiveness of different interface technologies in guiding pedestrians to their destinations. In contrast to other field studies, this article aims at investigating the influence of different interface technologies on spatial knowledge acquisition (spatial learning). With sufficient spatial knowledge about an environment, people can still find their way when navigation systems fail (e.g. out of battery). The goal of this article is to empirically evaluate three GPS-based navigation prototypes (implementing mobile map-based, AR-based, and voice-based guidance respectively) in supporting spatial knowledge acquisition. The field test showed that in terms of spatial knowledge acquisition, the three interface technologies led to comparable poor results, which were also not significantly different from each other. This article concludes with some implications for designing mobile pedestrian navigation systems.
Highlights
In recent years, interest in using mobile phones to assist pedestrian wayfinding in unfamiliar environments is increasing
We report the results of spatial knowledge acquisition
We only considered the results from participants who were unfamiliar with the sub-routes
Summary
Interest in using mobile phones to assist pedestrian wayfinding in unfamiliar environments is increasing. Different interface technologies can be used to communicate/convey route information to pedestrians, such as mobile maps, voice, 3D, images and augmented reality (AR). There are many field tests studying the effectiveness of different interface technologies in supporting pedestrian navigation (Rehrl et al, 2010; Walther-Franks, 2007), mainly focusing on how many errors they made during wayfinding, and how much time they took to finish the route. This article is interested in studying the influence of different interface technologies on spatial knowledge acquisition. With sufficient spatial knowledge about an environment, people can still find their way when navigation systems fail (e.g. out of battery). It is important to investigate how navigation systems affect the acquisition of spatial knowledge during navigation
