Passive Fatigue Assessment in Augmented Reality Workspaces: Behavioral Cues Indicators for Workers with Intellectual Disabilities

This study identifies challenges in user interface design for applying Augmented Reality (AR) technology to support work for individuals with intellectual disabilities. The main focus is on difficulty in self-assessing fatigue levels. The research methodology involved conducting experiments using HoloLens 2, analyzing changes in biometric information during fatigue, and examining the relationship between information display position and head orientation. Results indicate that changes in head height and orientation could potentially serve as fatigue indicators. In conclusion, while AR technology is effective in supporting work for individuals with intellectual disabilities, special considerations are necessary. Fatigue detection using biometric information and optimization of information display positions are crucial, and these findings may lead to safer and less burdensome use of AR.
