ABSTRACT
Analyzing the eye gaze to estimate the text understanding is a good way to overcome the drawbacks of classic question based assessment tests. In particular it does not suffer from random answers, question misunderstanding and can cover every parts of the text. In this paper we propose a method to estimate the objective understanding of a learner by analyzing his eye movements while reading. We conduct our experiment on Japanese texts and try to predict, by analyzing the eye gaze, how many questions about the texts the reader will be able to answer to. We show that we obtain 5.27% of error in the number of correct answers estimation by using eye gaze features. As a comparison, we try to predict the number of correct answers by using the reader's self assessment understanding and show that it leads to 9.04% error.

Eye gaze and text line matching for reading analysis
UbiComp/ISWC'15 Adjunct: Adjunct Proceedings of the 2015 ACM International Joint Conference on Pervasive and Ubiquitous Computing and Proceedings of the 2015 ACM International Symposium on Wearable ComputersEye tracking data has been widely used to analyze our reading behavior. Usually, experiments are carried out with head fixations or by analyzing eye tracking data in large areas such as paragraphs. But if we want to analyze the eye gaze line by line or ...
Eye-based head gestures
ETRA '12: Proceedings of the Symposium on Eye Tracking Research and ApplicationsA novel method for video-based head gesture recognition using eye information by an eye tracker has been proposed. The method uses a combination of gaze and eye movement to infer head gestures. Compared to other gesture-based methods a major advantage ...
