Abstract [en]

New societal requirements and functional growth put new demand on future driver information. Simultaneously, new technology and IT capabilities makes it possible to constantly adapt the information given to the driver for different reasons. Therefore, the aim of this thesis was to obtain an improved understanding, strengthen knowledge of the adaptive control of driver information to understand if, for what reason, when and where to use adaptive driver information (ADI). Also some possible new means to support drivers were suggested.The main purpose of driver information is to support the driver in achieving goals such as a safer, more environmentally friendly, more efficient, legal and enjoyable transportation by providing correct information and feedback.ADI can support the driver throughout development of skill and when performing operational, tactical, and strategic level tasks. Also tasks related to setting goals for the driving task and encouraging good driving behaviour can be supported. ADI can, furthermore help drivers to stay within their comfort zone by visualizing risk or certainty, identify and thereafter adapt how a message is communicated to different personalities, maintain the driver’s mental workload within the safe task load area by reducing demand when it is too high, increase mental workload by extra stimulating task during too low a mental demand, and minimize the risk for mismatches between effort and real demand.ADI changes automatically that may cause new and unpredictable issues reducing the purpose of driver information. These may include: mode confusion, function allocation, over and under trust, locus of control issues, skill degeneration and too low/high mental workload. Research has suggested that the most efficient way to reduce these issues is to make the driver and the automation (the agents) get along together and become team players. The team players should share goals, show intention, show limits of performance, state etcetera. However, for cars, a consumer product, in which visual demand is high, an approach can be where information vanishes when agents have become a “team”. This approach may be called “team building”.Research and industrial contributions has been presented. Several examples of how ADI can be carried out have been suggested and some even illustrated.

Abstract [en]

This study deals with a first step towards context adaptive functionality of a Driver Information System.Driving a car is a complex task for which the driver needs appropriate information to fulfil his or her goals. New technologies enable adaptability to driver state, task, personality etcetera and also to the context.The aim of this study was therefore to investigate what information people perceive that they need and want from the car in different contexts and to what extent there is consensus about the function. A new methodology was developed, and 33 private car drivers were interviewed and asked to rate a number of possible abstract functions in a car in different contexts.It was shown that people need and want different types of information in different contexts. It was furthermore indicated that there is sometimes a difference in drivers' opinions about what should be presented by the car and that there is varying consensus over different functions in different contexts. The rating result was illustrated by an easily perceived Context Function Matrix. The results may be used in the design of a context adaptive driver information system.

Abstract [en]

This study takes a starting point in what drivers do to avoid drowsiness while driving instead of starting with what researchers know is efficient (Take a short nap). It is concluded that research is missing when it comes to how efficient common behavior countermeasures are and that there is a mismatch between research and how people actually behave. A three stage approach which includes identification, information and countermeasure is suggested. Furthermore are a few ideas of what car manufacturers can do to support human behavior presented

Abstract [en]

Driving behaviour has been less documented than driver workload. The possibilities to define a framework that could be part of a driving behaviour model were investigated. The results present a framework that defines twelve scenarios in which drivers have misinterpreted a driving situation. The descriptions show evidence of increased user experience for some scenarios while other indicates reduced traffic safety. The results suggest that by using the framework-descriptions on how and why mismatches occur, design guidelines for in-vehicle systems can be developed.

Abstract [en]

Driver information is information that a driver needs to fulfil his or her goals of driving. Previously, information supported reliability in order to make the car work safely but, today, other attributes have become equally or more important. Driver information also needs to support safe, efficient, legal, environmentally friendly and enjoyable transportation.Functional growth is expected due to new technology, new purposes of driving and customers' desires. One way to meet functional growth and at the same time improve drivers' situation awareness and optimize workload may be to make driver information adaptive. The information presented, the output factors, could change salience governed by different input factors such as driver state, context, situation etc. However, changing information automatically may cause new types of errors, such as mode error, over-trust, under-trust, vigilance problems or change of locus of control. These types of errors belong to the category automation induced errors. The aim of this thesis was therefore to investigate whether adaptive driver information has a potential to improve driver performance, support goals of driving, improve situation awareness (SA) and optimize workload. This question was decomposed into four more specific research questions. (1) What are the purposes of future driver information and their relations to different functions? (2) What are the potential benefits and negative effects of adaptive driver information? (3) What information do drivers need and want throughout the driving task? (4) How can the negative aspects of adaptivity be avoided by design?In paper A, the purposes of driver information were identified and linked together with future driver information components and, as a result, several new functions were identified. The different benefits and negative effects were identified by literature studies. However, the scope was extended to the aviation and power industry, which has greater experience of automation. In paper B, functions were mapped to different contexts. The results can be used as a guideline for future design. The different negative effects of automation were handled in paper C by applying the "team player" approach to car design. The results showed a potential in the "team player" approach, but it was also clear that the visual impact on driving must be solved. It seems that adaptive driver information has a potential to improve driver performance, support goals of driving, improve situation awareness and optimize workload.

Abstract [en]

Automation can cause problems with ‘the human factor'. One approach is to make automation become a team player. A team player agrees on a common ground, they show intention, they show reasoning, express their limits of performance and so on. This approach has been applied to adaptive driver information in the present study. Ten experts on different in-vehicle systems were interviewed. The experts found the team play approach both challenging and interesting. However, the experts also found a difficulty in combining the increased visual workload required to "be a team player" with car driving, that is already visually, manually and cognitively challenging. The experts believed that the approach described by the researchers rather described agents before they become team players than being team players. What is needed is "teambuilding"; the solution suggested is a compromise and could be described as a separate view for the above mentioned information.
