与传统学习方法相比,教育虚拟现实可以通过提高学生的参与度或提高记忆力来帮助学生。然而,学生在 VR 环境中可能会因为压力、走神、不必要的噪音、外部警报等而分心。学生的视线可用于检测这些分心。我们探索基于深度学习的方法来检测注视数据中的干扰。我们设计了一个教育 VR 环境,并使用监督和无监督学习方法训练了三种深度学习模型(CNN、LSTM 和 CNN-LSTM)来衡量学生对注视数据的分心程度。我们的结果表明,与无监督学习方法相比,监督学习提供了更好的测试准确性。
Educational VR may help students by being more engaging or improving retention compared to traditional learning methods. However, a student can get distracted in a VR environment due to stress, mind-wandering, unwanted noise, external alerts, etc. Student eye gaze can be useful for detecting these distraction. We explore deep-learning-based approaches to detect distractions from gaze data. We designed an educational VR environment and trained three deep learning models (CNN, LSTM, and CNN-LSTM) to gauge a student’s distraction level from gaze data, using both supervised and unsupervised learning methods. Our results show that supervised learning provided better test accuracy compared to unsupervised learning methods.
