Towards a serious game based human-robot framework for fatigue assessment

Abstract

Fatigue is a prevalent and important symptom in many diseases and disorders. It may be categorized into two main types physical and cognitive. It is important to study both of these as in the real world they frequently occur at the same time. In this paper, a testbed to study physical and cognitive fatigue is introduced. The system utilizes a game and a robotic arm to induce cognitive and physical fatigue respectively. The game incorporated the N-back tasks to induce cognitive fatigue. The robotic arm induced physical fatigue by resisting subjects' movements. Results indicate that this system is able to induce cognitive fatigue, and also indicate new directions for future research
