Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- An experiment was set-up to investigate different joystick designs based on steer-by-wire technology. The experiment was carried out in a driving simulator. Both driving behaviour and perceived control of the car was registered and analysed. All participants had a SCI (Spinal Cord Injury) at cervical level, i.e. drivers with tetraplegia. Two types of joysticks were tested, one conventional (similar to what is used with computer games) and one modified with which the driver could control speed and steering independently. Both joysticks were tested with and without active feedback. The driving task consisted of rural road driving and a manoeuvre test with a double lane-change. The results presented here should be considered as preliminary and the study as a pilot study, which will be completed with a lager set of participants. So far 8 subjects have completed the experiment. The preliminary results cannot be used to draw any definite conclusion on which system design should be preferred. There was some evidence that active feedback provided a better lateral control and the drivers drove with larger safety margins with the modified joystick. However, the drivers’ opinion seemed to be more in favour of the conventional passive joystick.

Annan publikation (populärvet., debatt m.m.)abstract
- EFESOS is a Swedish Vehicle HMI (Human Machine Interaction) FFI research project. The overall ambition is to make driving of future cars more environmental friendly, enjoyable and safer by means of optimized systems. The project is managed by Volvo Car Corporation (VCC) and it is a collaboration between VCC and seven other research partners including Luleå University of Technology.

Konferensbidrag (refereegranskat)abstract
- The effects of a mobile telephone conversation on drivers' reaction time, lane position, speed level, and workload in two driving conditions (easy versus hard driving task) were studied in an advanced driving simulator. Forty subjects, experienced drivers in the ages 23-61 years, were randomly assigned to four experimental conditions. It was found that a mobile telephone conversation had a negative effect on drivers reaction time, when the driving task was easy. It led to a reduction in speed, when the driving task was easy. It had a negative effect on drivers' lane position, most pronounced when the tracking component of the driving task was difficult. Finally, it led to an increase in workload for both the easy and hard driving task. The effects were discussed in terms of what subtask, car driving or telephone conversation, the drivers gave the highest priority. Some implications for information systems in future cars are discussed.

Tidskriftsartikel (refereegranskat)abstract
- The effects of a mobile telephone task on drivers' reaction time, lane position, speed level, and workload were studied in two driving conditions (an easy or rather straight versus a hard or very curvy route). It was predicted that the mobile telephone task would have a negative effect on drivers' reaction time, lane position, and workload and lead to a reduction of speed. It was also predicted that the effects would be stronger for the hard driving task. The study was conducted in the VTI driving simulator. A total of 40 subjects, experienced drivers aged 23 to 61, were randomly assigned to four experimental conditions (telephone and easy or hard driving task versus control and easy or hard driving task). Contrary to the predictions, the strongest effects were found when the subjects were exposed to the easy driving task. In the condition where drivers had to perform the easy driving task, findings showed that a mobile telephone task had a negative effect on reaction time and led to a reduction of the speed level. In the condition where drivers had to perform the hard driving task, findings showed that a mobile telephone task had an effect only on the drivers' lateral position. Finally, the mobile telephone task led to an increased workload for both the easy and the hard driving task. The results are discussed in terms of which subtask, car driving or telephone task, the subjects gave the highest priority. Some implications for information systems in future cars are discussed
