Through the lessons with e-learning contents through client terminal, it is obvious that student can take the lessons much efficiently when the student are looking at the appropriate location at where the lecturers would like the students look at. It, however, is not always that the student is looking at the appropriate location even if the system indicates the appropriate location. The proposed system of lecturer’s e-table of server terminal allows monitoring the location at where each student is looking. Therefore, lecturer can make a caution to the student for the appropriate location at where the student has to be looking at. Through experiments with students, it is found that the achievement test score with the indication of appropriate location is much better than that without the indication. Also, learning efficiency with the caution is much greater than that without the caution.

INTRODUCTION e-learning is widely used for supplemental lessons with face-to-face lectures in a worldwide basis. The current problems of e-learning system is improvement of learning efficiency, effective e-learning contents (comprehensive), band width limitation, limitation of display size, question answering system, and authentication of students, etc. Other than these, students’ manner for taking lessons is another problem. It is not always that the students’ attitude for the lessons is properly right. Some of the students are looking at a different location at where e-learning content creators would like the students are looking at. Therefore, the achievement test score of the students is not good enough. Lecturer’s e-Table (Server Terminal) which allows monitoring the location at where each student is looking during lessons with e-learning contents through Client Terminals is proposed. Through the lessons with e-learning contents through client terminal, it is obvious that student can take the lessons much efficiently when the student are looking at the appropriate location at where the lecturers would like the students look at. It, however, is not always that the student is looking at the appropriate location even if the system indicates the appropriate location. The proposed system of lecturer ’s e-table of server terminal allows monitoring the location at where each student is looking. Therefore, lecturer can make a caution to the student for the appropriate location at where the student has to be looking at. Through experiments with students, it is found that the achievement test score with the indication of appropriate location is much better than that without the indication. Also, learning efficiency with the caution is much greater than that without the caution. Computer key-in system by human eyes only (just by sight) is proposed [1], [2]. The system allows key-in when student looks at the desired key (for a while or with blink) in the screen keyboard displayed onto computer screen. Also blink detection accuracy had to be improved [3], [4]. Meanwhile, influence due to students' head pose, different cornea curvature for each student, illumination conditions, background conditions, reflected image (environmental image) on students' eyes, eyelashes affecting to pupil center detection, un-intentional blink, etc. are eliminated for gaze detection accuracy improvement [5]-[11]. Also e-learning system with student confidence level evaluation is proposed [12]. Furthermore, gaze estimation method and accuracy evaluation are well reported [13]-[23]. The following section describes the proposed system followed by implementation of the system. Then some experiments with students is describes together with achievement test score. Finally, conclusion is described with some discussions. II. PROPOSED SYSTEM A.
