HMI considerations for the NL CVIS - SAFESPOT test site

This paper describes the Human-Machine-Interface (HMI) design approach for the integration of several cooperative systems that were developed in the projects CVIS and SAFESPOT. In this design approach, several important issues for integrated HMI were accounted for: the prioritization of the information for the highest safety relevance, the timing of the warning, and presenting the information in such way that the driver will act intuitively in the proper way and timely instant. The HMI design has been demonstrated at the Helmond test site. Experts have evaluated two applications (intersection and a lane-change application). The acceptance was rated positive for both systems, the trust in the systems was rated as adequate and the visual and acoustic warnings were rated as fairly easy to understand. In addition, the tactile and haptic warnings were rated as easier to understand compared to the visual/acoustic warnings. These results provide input for ongoing HMI design for cooperative systems
