Driver’s Distraction and Understandability of Using GPS Navigation

Abstract

GPS navigation is available on smartphone application providing turn-by-turn navigation instruction on smartphones and the distraction from GPS usage while driving also became an issue. In this paper, we present the strategy to mitigate the level of distraction by manipulating the type of display visual (2D and 3D) and placement (right, steer and left). We conducted field experiments in left-hand real traffic with 12 subjects. Our result illustrated that 3D conditions implied much fewer frequency of eye glances (FOG) than 2D conditions. Furthermore, steer conditions has much higher FOG than right and left placement conditions, but we found no significant effects on the ease of understanding (EOU) for visual display difference and the number of error for all conditions.
