 Issues in the Evaluation of Driver Distraction Associated with In-Vehicle Information and Telecommunications Systems 5/18/00 9:44:51 AM
Driver Workload Assessment of Route Guidance System Destination Entry While Driving: A Test Track Study 5/30/00 5:41:52 PM
 For navigation systems, how important a feature is the capability to view maps while driving (when the vehicle is in motion)?
Would you purchase a system that prevents you from entering a destination address while the vehicle is in motion?
 Given that many in-vehicle technologies are now available and being used in Japan, what lessons can you offer to make these systems safer for drivers? 7/6/00 11:38:54 AM

Before giving my view regarding this, I would like to point out that there are differences between the two countries and that some aspects will not translate from one country to the other.
In 1989, when the first "accurate-to-the-exact-street" navigation system for the Japanese market came out, there was much discussion as to how much information should be shown to the driver while the car was in motion. There was also concern over operation of the navigation system, such as inputting destinations. After much debate, it was decided that the major automotive OEMs would get together and conduct research to form the basis for common guidelines that would ensure good usable products while ensuring safety.
Reviews of previous research and follow up experiments with various systems and loads were conducted to come up with what is called the JAMA guidelines. (JAMA: Japanese Automobile Manufacturing Association.) The guidelines have undergone couple of revisions as technology emerged, such as when communication of real-time traffic information became common.
I would not want to use the expression "learn", but rather address what is worth considering when developing and marketing such new in-vehicle systems. Below are personal views that I believe many of my colleagues share.
- Human nature; Will the product (even if unintentionally) cause "human nature" to do what is not rationally safe? If the answer is yes, then consideration should be given as to how these systems are designed and marketed.
- The Good and the BAD; Will the public benefit from these systems? If so, we should seek to ensure that the merits from these systems will be realized without getting overly cautious and killing the good in them. Therefore, guidelines must be practical. We cannot expect perfection.
- Cooperation & Competition Without going against anti-trust issues, there should be good (honest) cooperation between OEMs so that logically and practically correct systems emerge and competition will be fought in areas where we will not sacrifice safety. Having certain restrictions will in many cases spawn new innovative design that are easier to use as well as being safer. This is healthy competition.
- Timing is crucial. It is difficult to come to consensus once products come out in great numbers. After committing to a certain design, there could be a tendency for non-logical factors to dominate discussions. So it is better to come to a timely conclusion of a Grade-B solution rather than waiting forever for a Grade-A solution. In some cases, "Good is better than best, because best may never come."
- Flexibility. Since technology evolves, we should be prepared to change guidelines to match these changes. There should be an institutional effort and climate that facilitates this making it possible to observe timing issues mentioned above (number 4).
