European approaches to principles, codes, guidelines, and checklists for in-vehicle HMI

With driver distraction an increasing concern in the context of the proliferation of in-vehicle displays and information systems, this chapter focuses on the design and assessment of in-vehicle human-machine interaction (HMI) within Europe with specific examples drawn from the United Kingdom. The European esafety program is shaping the approach to the design and assessment of both driver information and assistance systems, which are expected to provide major contributions to accident reduction targets. Even though these systems are expected to have a positive effect on safety, a key issue is to ensure that any negative consequences from driver distraction are minimised or eliminated. This study describes the development and content of the European Statements of Principle (ESoP) on HMI, which provide high level design guidelines for information and communication systems and aim to promote systems that are usable and safe, taking full account of the potential for driver distraction. The challenge of quantitative measurement of distraction is noted and a UK approach to assessment of HMI, based on an expert checklist, is described. Finally, the chapter discusses the design and assessment of driver assistance systems and the emergence of a code of practice being developed within a manufacturer-led European project.
