ABSTRACT
LED visualizations in the car are primarily used to direct the driver's attention to obstacles or hazards in the environment. An ambient LED arrangement can indicate the horizontal position of outside objects without obstructing the driver's field of view. How accurately the LEDs represent the spatial position of an outside object and how well it can be distinguished from other nearby objects is influenced by several factors. Our aim is to increase the spatial accuracy of a windshield-mounted horizontal LED visualization. Our approach is to use a calibration procedure to increase this accuracy. In an experimental study in our driving simulator, we found that calibration increased the spatial accuracy and, as a result, the recognition reliability (in our setup from 67% to 95%) and that a 3-point calibration is sufficient in comparison to more calibration points.

LED Visualizations for Drivers' Attention: An Exploratory Study on Experience and Associated Information Contents
AutomotiveUI '18: Adjunct Proceedings of the 10th International Conference on Automotive User Interfaces and Interactive Vehicular ApplicationsWhen it comes to highly automated driving, several studies indicate that drivers should be "kept in the loop" when driving in automated mode in order to be better prepared when they need to take over. The challenge lies in finding a way that raises the ...
