EMPIRICAL COMPARISON OF THE USE OF DISTANCE VERSUS LANDMARK INFORMATION WITHIN THE HUMAN-MACHINE INTERFACE FOR VEHICLE NAVIGATION SYSTEMS
Current in vehicle navigation systems place an emphasis on the use of distances within their turn-by-turn directions. Previous work has shown the potential for landmarks, particularly in relation to subjective aspects of system usability e.g. confidence in navigation. To test the objective benefits of landmarks versus distances, road based trials were conducted in which 28 participants drove unfamiliar routes within an urban area using a simulated navigation system that emphasizes either landmarks or distances for the purposes of locating maneuvers. When using the landmark system, relatively few glances were made towards the navigation display and workload was perceived to be lower, in comparison with the figures attained for the distance system. Furthermore, the duration of glances towards the landmark display was low. Nevertheless, the participants made some navigational errors when using landmarks. The results are discussed in relation to the design of future landmark-oriented navigation systems.
