We investigated a driver’s gazing time during backing vehicle maneuvers in a 90-degree reverse parking system for the phase from start to the 5-m point (start phase) and the phase from backing from the 5-m point to stop (stop phase). The objective of this study was to elucidate the driver’s gaze while approaching the parking area and in the parking area during backing. We used a sport utility vehicle with the driver’s seat at the right-hand side. We modified the vehicle with four technological conditions: no-tech vehicle, sonar vehicle, backup-camera vehicle, and backup camera with sonar vehicle. The monitor, rearview mirror, left-side mirror, and right-side mirror were designated as the area of interest (AOI) in the gaze. For the start phase, there were no significant differences in the total gazing time of all the AOIs in the four technologies. For the stop phase, however, the total gazing time of all the AOIs for the vehicle with a backup camera was significantly longer than that of the vehicle without a backup camera owing to the increase in the gazing time of the monitor. The results obtained from these experiments will form a basis for the future development of vehicle camera systems.
