Abstract

Driving under fatigue is one of the main causes for deadly accidents in car and truck traffic. One of three reasons for fatigue, next to mental overload and sleep deprivation, is monotony. The article will detail a concept for an automotive driver-vehicle-interaction system that was developed to prevent monotony caused fatigue. Inspired through proven positive effects of a co-driver in monotone driving situations, the driver-vehicle-interaction system will be a technical realization of a passenger. A passenger has both positive and negative influences on the driver. The goal for the driver-vehicle-interaction system is therefore to replicate the positive influences while avoiding the negative. The system will - like a passenger - animate the driver to talk, think and listen. In order to avoid distraction all interaction will be based on the driving situation itself. Therefore, the driver is not distracted by a secondary task, but the actual monotonous driving task is interesting again by new stimulus. For example, the driver is asked by the driver-vehicle-interaction-system to maneuver the vehicle center as precisely as possible in the middle of the lane for one minute. This task addresses an increasing difficulty for the drivers to keep the lane in monotone driving situations. In addition, 13 tasks and questions where developed to maintain the driver’s vigilance. In order to motivate the driver to use the system, the interaction is gamified. The gamification implies a feedback for the driver on his fulfilment of tasks combined with a rewarding scoring system against other traffic participants. At this state the concept is developed to be tested in a simulated driving scenario.
