Current in-vehicle navigation systems place an emphasis on the use of distances within their turn-by-turn directions (e.g. left turn in 300 meters). Previous work has shown the potential for landmarks (e.g. traffic lights, churches), particularly in relation to subjective aspects of system usability e. g. confidence in navigating. 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 (turn-by-turn directions on both a display and voice) that emphasized 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, participants made some navigational errors when using landmarks. The results are discussed in relation to the design of future 'landmark-oriented' navigation systems.
