This study aimed to reduce the effect of the examining environment on accuracy by using an eye movement detection system, a VR head-mounted display. We reproduced the inspection environment in a virtual reality environment and performed the cover test, a basic inspection technique for tropia and phoria. We then developed a system that uses eye data collected by eye tracking to detect the directions and magnitudes of eye misalignment. The Maddox method, an existing testing procedure, was used to verify the accuracy. We have confirmed its effectiveness in detecting the directions and magnitudes of horizontal eye misalignment.

In this study, we implemented the Cover Test, a test method for diagnosing eye misalignment using a head-mounted display with an eye-tracking capability. Specifically, we created a virtual examination environment in a VR space. The eye-tracking technique collected eye movements immediately after the covering or uncovering of the eyes. Thus, we calculated the amount of eye deviation and developed a system to determine the presence and magnitude of strabismus and heterophoria.We assessed the system in the verification experiment by examining the consistency between the judgment results provided by this system and the clinical evaluation approach with the Maddox rod. The result was that we could verify the horizontal eye movements more accurately.

In previous research, we developed a method to automate the conventional evaluation of eye misalignment (cover test) and distinguish misaligned eyes from their movements. However, this method had the problem that vertical eye movements were affected by the eyelids and eyelashes, and could not be completely detected. To solve this problem, we have developed another method to recognize abnormalities by observing only the movement near the center of the pupil.

Authorship：Principal investigator
本研究では，講義中の受講者の振る舞いから，その受講者が講義内容をどの程度理解できているかを推定することを目指す．そのために，「ビデオカメラ等で観測した受講者の振る舞いを計算機により自動的に分類する技術」「受講者に対して講義中に実施する講義の理解度アンケートや講義内容に関する小テストの結果から，受講者の理解度を客観的に推定する技術」「求めた客観的理解度を Ground Truth とみなして，分類した受講者の振る舞いとの関連を求めることで，受講者の振る舞いから客観的理解度を推定する技術」の３つの技術を開発する．
