This paper provides an overview of topics that need to be addressed in developing standards for driver interfaces of the future. To provide context, this paper identifies 14 characteristics of a successful standards development effort (e.g., minimal work item overlap, adequate working group expertise, achievable compliance). The paper then reviews the current work program of International Standards Organization Technical Committee 22, Subcommittee 13, Working Group 8 (Ergonomics of Road Vehicles-Transport Information and Controls Systems - ISO TC 22/SC 13/WG 8). Multiple perspectives (human information processing, safety, etc.) are used to identify gaps in the WG8 standard program. Needed are standards for (1) excess visual demand, (2) excess cognitive demand, (3) interruptions that supercede driving, (4) auditory information, (5) workload managers, (6) telephone interfaces (especially those with Bluetooth features), (7) personal digital assistants (PDAs), (8) large area head-up displays (HUDs), and (9) wearable computers. Where feasible, standards should not only include assessment procedures but design data and methods as well.

Although the WG 8 experts have been engaged in an extensive effort to develop standards, there is more work than they can handle, and their workload is increasing. To provide the needed personnel and research information, greater effort is needed to recruit participants from the new and now more significant organizations in the automotive industry--tier 1 suppliers, electronics suppliers, service providers, computer companies, and the telephone companies. A significant and immediate increase in research funding to support standards development is also needed. Opportunities to expand use the web to disseminate information should be explored.
