Evaluation of e-learning contents presentation methods using an eye mark recorder

The main idea of this paper is to evaluate e-learning contents (text contents, illustration contents, animation contents, and video clip contents) presentation methods using an eye mark recorder in order to improve the content presentation methods. This paper compares the averages of learners' pupil sizes during learning various kinds of contents. The results show that animation contents and video clip contents are effective presentation method to maintain learner's attention. In addition, this study proposes an e-learning content presentation method using animated agent and various kinds of attention cues in order to relieve the learner's mental workload in e-learning. The results obtained from these experiments show that the proposed method is effective in easing the learners' mental workload.
