Information Sharing to Improve Understanding of Proactive Braking Intervention for Elderly Drivers

In this study, we focus on how effective information sharing is as a practical method of improving elderly drivers’ understanding of a proactive braking intervention system that operates several seconds before a driver enters a dangerous situation. At first, we discuss the perceiving process of provided information using the basic concept of information sharing. Then, we implement some prototypes of visual content for the head-up display. After that, we investigate basic characteristics of the various usages of the implemented prototype visual content using questionnaires. As a result of our experiments using a driving simulator, we confirm that information sharing that includes visual content is effective in improving elderly drivers’ understanding of benefits and trust of the system. In addition, from the comparisons between single use and multiple use of visual content, we propose some methods of further improvements in preventing information overload.
