The Role of Standards for In-Vehicle MMI
Andrew Parkes University of Leeds, UK
National and international standards are being raised for in-vehicle man- machine interaction (MMI). That is, not just criteria for the physical characteristics of the interface displays and controls, but also the form and content of the "dialogue" between the driver and the vehicle. The scope of such standards will grow ever wider as the potential of display and control devices, and the range of applications and services within the vehicle, increases. Such developments are controversial, and two questions need to be answered: Can useful standards be developed? Should such standards be developed?
Much of the material presented here was stimulated by a panel discussion at the International Ergonomics Association Symposium on IVHS/RTI ( 1994). This discussion drew together academics and industrial speakers from Europe, the United States, and Japan, and covered the history of in-vehicle standards, current initiatives, and hopes for the future. Although stimulated by a particular event in time, it is hoped that this discussion of the role of standards in in-vehicle MMI raises general issues for the contribution of human factors and ergonomics in the systems design process.
There are two terms that occur frequently in the discussion of in-vehicle MMI: transport information and control systems (TICS) and road transport informatics (RTI). Neither term is defined precisely. Both are seen as
