Outline of Final Research Achievements

In this research, we have developed two methods that can evaluate various driving conditions for people with cognitive impairment. One is a hazard perception evaluation using so-called virtual reality using a head mounted display (HMD). Hazard perception is the perception of recognizing a place where danger is hidden, and this is used in this evaluation. The subject wore the HMD to simulate the actual driving and to identify dangerous points. The other is on-road driving assessment. These were created from previous studies, and after hearings from teaching instructors and occupational therapists who had driving evaluation for patients. Currently, these are being made into papers and are in the middle of actual operation.

Academic Significance and Societal Importance of the Research Achievements

脳損傷者などの認知障害者の自動車運転の評価は、医学の領域だけでなく一般社会にも大きな問題となっている。これまでは、これら認知障害者の自動車運転において根拠に基づいた評価が存在しなかった。しかし、今回の評価の開発により、これらの対象における運転技能を把握することができる一歩となり、今後の研究を含めて安全運転を評価する一助となることが考えられた。これら罹患者の運転技能を正確に評価することは、罹患者たちの社会生活を充実するだけでなく、一般の国民の安全を確保することにもつながると考える。
