The main goal with this project is to evaluate whether the HMI (Human-Machine Interface) checklist and the DRT (Detection-Response Task) test method are applicable for Euro NCAP's future assessment protocol. This has not been done before in Sweden, the area is new and under development within the Euro NCAP organization. Development work is underway in Australia, and Euro NCAP has had access to the test methods used there by researchers and authorities. We want to evaluate these methods for application in Sweden and Europe. The DRT methodology is used to compare different car brand´s IVIS (In-Vehicle Infotainment Systems) and ADAS (Advanced Driver Assistance Systems) by measuring the effects of cognitive load on driver attention. The DRT method is based on a simple detection-response task where participants respond to relatively frequent artificial stimuli presented with a specified degree of temporal uncertainty. Detection performance, measured in terms of response time and hit rate, is assumed to represent the degree to which attention is affected by the demand, and particularly the cognitive load component imposed by the secondary task under evaluation. Longer reaction times and reduced hit rate are indicative of higher cognitive load. The checklist is divided in three parts, training part, part 1 and part 2.
