Driver information systems that are likely to see more widespread implementation in future vehicles include: cellular phones, adaptive cruise control, navigation, package/cargp and vehicle tracking, and night vision systems. To interact with those systems, use of menu-based architectures and speech input/output will increase
In projecting what might appear in future products, the key considerations are usefulness, usability, and cost. To achieve the desired levels of usability for these interfaces, more research is needed to provide (1) basic models of driving and related baseline data, along with a greater understanding of the workload of driving; (2) application-specific data on most of the new systems; (3) safety data on their actual use; and (4) low-cost usability assessment tools. More work also needs to be done to disseminate human factors knowledge to suppliers and to educate them in iterative design and the use of driver interface prototyping tools.
