4.2. Methods of Measuring Driving Ability
MOTION SICKNESS
This study was conducted without using a driving simulator or examiner evaluation. After consideration and deliberation, the examiner’s evaluation was employed; however, some points still needed to be considered. Lee et al. compared driving performance in a driving simulator and on-road driving, showing a significant positive correlation [Negative aspects of driving simulators have also been reported. Matas et al. reported that older adults are at a higher risk for driving simulator sickness. Moreover, they found that being female and having a history of motion sickness were associated with driving simulator sickness [In the present study, we evaluated driving ability on the road by an examiner to prevent motion sickness symptoms, as measured by a simulator, because this study was conducted on older participants. The possibility of performing measurements under more realistic conditions was also investigated. In this study, no comparison was made between the evaluations by the simulators and examiners. As automobile driving techniques continue developing, measurement methods must be re-examined.
