While reading the chapter on Ergonomics and Human Factors I found the statement I was looking for. It’s hard to find definite answers of course, but since the first time I heard about In-vehicle information systems (IVIS) I wondered if they really were effective.
Although the safety potential is huge, the ultimate effects are definitely smaller than expected. If these systems are included in the vehicle, they would work perfectly if everything remained the same. But when one thing inside the vehicle is changed, this will inherently change the behavior of the driver: everything is connected.
Some of the possible negative effects of the IVIS – the book mentions ITS, Intelligent Transport Systems – are:
1) Underload and diminished attention level;
2) Information overload (Google Glass and all AR things, please do watch out);
3) Incorrect interpretation of information;
4) Overreliance on the system;
5) Risk compensation.
This is definitely interesting, although quite intuitive for anyone with minimal knowledge on cognition.
Do engineers consider this when they conceive these systems? I know nowadays most of them have psychologists or ergonomists on their teams, but some of them still don’t.
And these systems worked rather well on aeronautics contexts, but it seems as if they were blindly applied to the automotive sector.
More on this on the future, definitely.
