Effects of In-Car Navigation Systems on User Perception of the Spatial Environment

摘要

This study aims to understand how navigation devices affect driver's awareness of the environment. The hypothesis of this study suggests that use of in-car navigation systems diverts driver's attention from outside of the car to the inside where external objects are less likely to be recognized. These objects may include landmarks, buildings, traffic signs and even pedestrians. Further, internet connected navigation devices cause the amount of information presented to user become very large in size during driving. This study conducted a multiuser field experiment in order to understand basic effects of in-car navigation systems on user perception of external world outside of the car. It was also hypothesized that technology aptitude of driver has significant contribution on how these devices affect user's perception. Results suggested that in-car navigation systems has adverse effects on external world perception. Technology aptitude of the driver played significant role on navigation device interaction as well.
