Watch out! User-centered Feedback Design for a V2X-Smartphone App
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.
