Abstract [en]

Driving simulators of today are lacking the full third visual dimension. This makes comparing driving simulators with driving in real life problematic. Thus it is important to improve the simulators' validity. The present study investigated whether the depth cue observer-produced motion parallax (Obs-PMP) affects drivers’ performance and perception of presence. Twenty-two participants (11 males and 11 females) drove in a driving simulator with and without Obs-PMP. An experiment with two scenarios was conducted, in which one scenario took place in an urban environment and one in a rural environment. Distance estimation, judgments of speed and perceived virtual presence was investigated. An effect of Obs-PMP on lateral positioning of the car just before an overtaking and of scenario on head movement was found. This suggests that Obs-PMP affects driver’s performance in driving simulators and motivates further research on the area, e.g. comparing simulators with real life scenarios.

Abstract [sv]

Körsimulatorer idag saknar en tredje visuell dimension. Detta gör att jämförelser av körsimulatorer med körning i verkliga livet blir problematiskt. Därför är det viktigt att förbättra simulatorernas validitet. Denna studie undersökte huruvida införandet av observatör-producerat rörelse parallax (Obs-PMP) påverkar förarnas prestationer och perception av viruell närvaro. Tjugotvå deltagare (11 män och 11 kvinnor) körde i en körsimulator med och utan Obs-PMP. Ett experiment med två scenarier genomfördes, ett scenario ägde rum i en urban miljö och ett annat på en landsväg. Avstånds- och hastighetsuppfattning samt upplevd virtuell närvaro undersöktes. En effekt av obs-PMP på lateral placering av bilen precis innan en omkörning samt av scenario på huvudrörelser hittades. Detta tyder på att obs-PMP påverkar förarens prestationsförmåga i körsimulatorer och motiverar ytterligare utredning och forskning för att bland annat jämföra simulatorer med verkliga scenarier.
