Measuring physical demand in Augmented Reality learning environments
研究了增强现实教育环境中长期使用AR对身体需求的影响，通过动作捕捉、NASA任务负荷指数和HoloLens眼动追踪量化用户姿势、参与度和感知负荷，发现弯腰分数与身体需求分数强相关。
Augmented Reality revolutionises education by enhancing learning with interactive, immersive experiences. However, the impact of long-term AR use, particularly in terms of physical demand, within educational environments remains poorly understood. This study investigates the relationship between AR engagement and physical demand, utilising motion capture technology, NASA Task Load Index, and HoloLens eye-tracking to quantify user posture, engagement, and perceived workload. We hypothesise that prolonged AR interaction results in a change in slouching scores, indicating increased fatigue. The results show a strong correlation between the slouching score and the NASA-TLX physical demand score. Our study lays the groundwork for incorporating predictive modelling to develop proactive physical demand measures.
