Bryan started his keynote talk the automotive user interface conference (auto-ui.org) in Salzburg with reminding us that having controversial discussions about the HMI in the car is not new. Quoting a newspaper article from the 1930s on the introduction of the radio in the car and its impact on the driver he picked an interesting example, that can be seen as the root of many issues we have now with infotainment systems in the car.
Over the last 100 years cars have changes significantly! Looking more closely Bryan argues that much of the chance happened in the last 10 years. There has been little change from the 1950s to the 1990s with regard to the car user interface.
Even given these developments it is apparent that driving has become safer. Passive safety has been improved massively and this made driving much safer. There seems to be a drawback to this as well, as people may take greater risks as they feel safer. The next step is really to avoid accidence in the first place. Bryan argues that the interaction between driver, environment, and vehicles is very important in that. He suggests that we should make more of an effort to create systems that fit the drivers.
Visual distraction is an obvious factor and much discussed in the papers at the conference – but Bryan argued that “eyes on the road” is not equal to “mind on the road”. I think this is really a very important point. Ensuring that people keep their eyes on the road, seeing things is not enough. The big resulting question is how to keep or get people focused on the street and environment. It seems there is some more research to do…
The variety of interfaces and interaction metaphors build into cars opens more choices but at the same time creates problems, as people need to learn and understand them. A simple question such as: How do you switch the car off? may be hard to answer (Bryan had the example of a car with a push button starter, where you cannot remove the key). I think there are simple questions that can be learned from industry and production machines… add an emergency stop button and make it mandatory ;-)
