Outline of Final Research Achievements

In this research project, we hypothesized that inducing intrinsic motivation in humans would lead to the maintenance of arousal levels, and verified this. In addition, we aimed to establish and optimize a method for maintaining arousal level by inducing intrinsic motivation, with the aim of applying it to people engaged in safety-critical operations. The research results are summarized below; 1) Realization of methods to induce intrinsic motivation based on knowledge in the field of psychology. 2) Verification of the effect of maintaining arousal level when information that induces intrinsic motivation is presented to the operator. 3) Establish a method for predicting changes in individual arousal levels by machine learning and presenting information at effective timings. 4) Clarification of the effectiveness of the proposed method compared with the arousal maintenance method (sound, vibration, gum chewing) by external stimulus.

Academic Significance and Societal Importance of the Research Achievements

本研究課題は、非侵襲的かつリアルタイムでの生理反応の計測とデータ処理、及び、機械学習による予測モデルの活用という、新たな諸技術によって可能な方法で取り組むテーマでもあり、その成果は、心理学、生理学、情報科学、データサイエンスなど、複数の領域と接する人間工学の新たな発展可能性を示すものと考える。
また、運輸事業をはじめとした安全致命性の高いオペレーションに従事する人にとって、覚醒水準を適切に保つことは、事故防止の観点から極めて重要な課題であることは疑いがなく、人に不快さを与えず覚醒水準を維持する新たな手法の提案は、特にシステムの自動化が進む今日において、新たな問題解決を与えるものといえる。
