Outline of Final Research Achievements

The goal of this study is to automatically recognize the level of engagement of the user of an e-learning system based on video data. If the system can recognize the decrease in level of engagement, it may be possible to support the user appropriately.

In this research, we showed that the level of engagement is reflected in the eye movements. In particular, the frequency of blinking and the duration of blinks are found to be negatively correlated with the level of engagement , and the aspect ratio of the eye and the distance between the eye and the screen are found to be positively correlated with the level of engagement. We modeled the relationship between the level of engagement and eye movements, and proposed a probabilistic method for automatic estimation of the level of engagement. It was shown that as the level of engagement increased, so did the model-based estimate of the probability of engagement.
