Watch Out!User-Centered Feedback Design for a V2X-Smartphone App

摘要

Mobility is a fast developing, technological and simultaneously human field of research. V2X-technology is one major contributor that will influence the behavior, efficiency and safety of traffic participants. To include all participating members of traffic, we developed a V2X-smartphone application to empower vulnerable road user to be part of the technological integration. With a two-tiered research approach, we focused on both, the iconography and the feedback design of that application. One key finding of the presented work is a clear recommendation of combined features (color, size and geometrical form) for rear-end collision scenarios. The article concludes with practical recommendations that facilitate visualization-varieties from a users' perspective.
