To minimize the mental workload for the driver and to keep the increasing amount of information easily accessible, sophisticated display and interaction techniques are essential. This contribution focuses on a user-centered analysis for an authoritative grading of head-up displays (HUDs) in cars. Two studies delivered the evaluation data. In a field test,(More)
OBJECTIVE The aim of this study was to quantify the impact of traffic density and verbal tasks on takeover performance in highly automated driving. BACKGROUND In highly automated vehicles, the driver has to occasionally take over vehicle control when approaching system limits. To ensure safety, the ability of the driver to regain control of the driving(More)
– This contribution provides a review of fundamental goals, development and future perspectives of driver assistance systems. Mobility is a fundamental desire of mankind. Virtually any society strives for safe and efficient mobility at low ecological and economic costs. Nevertheless, its technical implementation significantly differs among societies,(More)
Although research on adaptive systems has begun only recently, studies have shown the benefits of using adaptive systems. However most of those studies have examined systems with and without adaptive qualities, disregarding additional factors that may influence the interaction. This study presents a first step towards a more comprehensive evaluation of(More)
The aim of this study is to find out if hand gestures can reasonably be used to control in-car devices. Therefore, a set of consistent gestures which allow intuitive human machine interaction is searched. The results show a consistent gesture vocabulary for a variety of devices. Since this study is extremely dependent on its environment, in this paper(More)
The increasing traffic volume confronts the road user with a challenging task. The high number of traffic deaths might not be reducible with passive safety alone. However systems that actively influence the guidance of vehicles, like assistance and automation systems, can make a difference towards higher safety, comfort and efficiency. Some of these systems(More)
In this study, the haptical and gestural user input modes are compared with regard to distraction from a controlling task similar to steering a car. The examination is carried out in a driving-simulation laboratory. While performing the controlling task permanently, the test subject has to execute a variety of user input with a given modality. Haptical(More)
