Unless the vehicle is stationary, the driver's primary concern is to perform operational tasks such as course holding, tactical manoeuvres such as overtaking or crossing an intersection and the strategical task of navigation. In the performance of all these tasks the driver is assisted by in-vehicle and road-side information, provided by equipment that is becoming increasingly complicated and sophisticated. Interaction with in-vehicle equipment in particular directly competes with the primary task of vehicle control and may impede with the driver's performance if the interaction distracts the driver's attention, results in an information overload or produces irrelevant or confusing information. confusing information. Optimal design takes account of the driver's limitations, and takes account of the fact that the requirement in-vehicle interaction has to fulfil are highly dynamic. The key concept in in-vehicle interaction design is therefore that of adaptive systems. (A)
