Abstract—Strabismus is one of the common vision disorders. For people with mild strabismus, many evidences showed that doing eye muscle exercise would be very helpful to straighten the weak eyes and improve eye performance eventually. In this paper, we propose aneye-trackingaided training system for strabismus therapy. We aim at helping strabismus people train eye muscle movements with a real-time training system. The disparities of the two eye gazes of strabismus sufferers are displayed on the screen immediately, providing real time and interactive feedback.Four subjects with strabismus and three subjects with normal eyes were invited to participate in the training with the proposed system. In this study, we achieved very promising results that demonstrated the effectiveness of the proposed training system and the possibilities of using this system in the real life applications.
