Cognitive Function Training System Using Game-Based Design for Elderly Drivers

摘要

It has been found that age-related decline of cognitive ability is one of risk factors for traffic accidents among the elderly. Therefore, the present study introduced a new game-based cognitive function training system, which was designed by cognitive evaluation theory, gamification, interface design guidelines for driver-assistance systems and fuben-eki principle. It uses a trail making game to train and measure driver's visual attention ability, and the score was transformed to limit the vehicle's maximum velocity. Simulator experiments were performed to verify that it enlarged the degree of useful field of view to enhance the hazard perception ability.
