Increase of information displays and controls. More complex cockpit looking more similar to an airplane cockpit. Navigation display with entertainment system, controls at the steering wheel, Board computer with vehicle information, lots of controls in the midconsole for suspension settings, climate controlm entertainment etc. Titel van de presentatie 16-06-11

Driver observation needed to provide the best support for each individual driver at the right time It’s challenging because of the amount of characteristics and environments, so start easily
Workload Estimator output.
The work load experiences affect the task performance of the road user. In general it is assumed that an optimum work load exists that enable a road user to perform optimally (see De Waard, 1996). The level of the work load of a task is determined by the following factors: The environment. A certain manoeuvre in a busy environment (urban with a lot of other traffic) leads to a higher work load than the same manoeuvre in a quieter environment. The normative task . What does a situation demand of a driver to perform a task correctly and safely? The normative task as presented in chapter 5 makes a distinction by perceptual, cognitive and motoric elements of the sub-tasks and is an extension of the task analysis of Richard, Campbell, and Brown, (2006). Normative means the desired behaviour. Secondary tasks. Secondary tasks are not directly related to the driving task (e.g., phoning or searching for a radio channel when driving). Performing a secondary task can increase the work load of the driver and systems related to driving (such as in-vehicle systems) may also require attention from a driver and thus raise the work load. Stable road user characteristics . General driving experience and experience of certain situations enable certain actions to be automated, therefore demanding less work load. The work load is also affected if the subjectively experienced task competence is considered insufficient for the task requirements (Fuller, 2008). Temporary road user characteristics . Also variable characteristics like tiredness and stress affect the work load experienced. Stress caused by lack of time may reduce information processing capacity (Ozel, 2001).

Rapid Prototyping enables fast iterations of multiple design solutions, constantly improving on the product before or during technical implementation.

Generic for all type of systems and applications Low processing time Prevent information overload Rank messages on priority Taking traffic situation into account – context awareness Generic – so no complex interfaces and protocols Low processig time – no complex algorithms Main goal is to prevent information overload that prevents the driver from reaction correctly to the situation. Prio ordering Traffic situation – the workload of the driver. With the HMI manager also overload situations will be prevented More participants preferred the AIDE condition to the Non-AIDE condition Titel van de presentatie 16-06-11
