ABSTRACT

OBJECTIVE: This study examined the effect of the use of three different interfaces of navigator system on driving of 20 young subjects . BACKGROUND: Various studies have indicated that the non immediate comprehension of traditional Satellite Navigation (Sat Nav) map data may lead to increased driver distraction. At the moment the information presented in a Sat-Nav Telematic system is designed using a static view visual model, which does not take sufficiently into consideration the dynamic time space nature of the car environment. DHS set about designing a different kind of interface which takes into consideration specific time space stimuli restrucutring the data feed so that the mind is bctter tuned in the dynamic car environement. For this reason two new navigator system interfaces , where the indications arc bascd on spccific landmarks, are proposed. These navigator system interfaces were tested and compared to a Standard Sat Nav system in order to evaluate the effects produced on driver' 3D kinematics. METHOD: the drivers followed an urban route in a driving simulator following the voice commands given to them by three different navigation systems : the first Satellite navigation traditional system (Sat-Nav), the second one based on the use of landmarks able to provide detailed information about the map (2-Me system) and the third one with the same landmarks but with a different map representation (C -Me) .
