The automotive industry continues to hold a central role in transportation and is constantlyundergoing multiple innovations. Among these, Camera Monitor Systems (CMS) have emergedas a digital alternative to conventional side-view mirrors, offering advantages such as improvedaerodynamics and enhanced visibility in poor weather or low-light conditions. However,challenges related to depth perception remain, as replacing mirrors with screens reduces theavailability of depth cues. This thesis investigates how CMS configuration, specifically CameraPosition and Field of View, affects distance judgment and safety-related decision making duringdriving. In addition, a previously unexplored aspect is investigated here: whether usercharacteristics affect interaction with the system and performance when using it. In particular, ageis investigated, given its implications for visual perception and changes in driving behaviourThirty drivers of varied ages were recruited and completed two simulated driving tasks. The firstwas a distance estimation task, in which they reported the distance of a following vehicle fromtheir car. The second was a Last Safe Gap task, in which they indicated the latest safe moment atwhich they would change lanes before being overtaken. Results showed that both CameraPosition and Field of View significantly affected drivers’ performance. Wider Field of Views andlower Camera Positions generally reduced distance underestimation errors (happening whenreporting a chasing vehicle being closer than it actually is) as well as the Time to Contact valuesselected when reporting the Last Safe Gap for lane changes. Notably, age emerged as asignificant factor, with older participants performing with greater accuracy in distance judgmentand more conservative gaps in LSG selection compared to their younger counterparts. Thesefindings demonstrate that CMS performance is shaped not only by system configuration but alsoby user characteristics. Accounting for such variability is essential for designing and optimisingCMS that support safe and effective use across the driving population.
