Development of a Personalized Learning System Using Gaze Tracking System

摘要

Providing timely feedback is crucial for a successful personalized e-learning system. A personalized learning system with e-learning contents combined with an eye movement tracking device has been developed with an open source-based gaze tracking system. The effects of feedback delivered to learners depend upon learners' attention while gazing at the e-learning contents have been tested based on learners' academic achievement. It is found that the experimental group with feedback based on eye-movement shows higher scores than the controlled group without feedback using eye tracking devices. Also more eye fixation time and fixed point numbers appeared in learners of the experimental group than the controlled group, and thus it can be said that more visual attention was possible with the gaze tracking feedback system. These finding show that feedback using eye movement information may contribute to better interactions between learner and contents, and thus create a more effective e-learning system.
