Abstract
A training improves sight and function of eye-movements. This is called vision training. Vision training has advantage for people because they can improve their eye-function themselves without medical treatment or surgery. However, vision training has a limitation in the diagnosis of eye movement, depends on optometrists’skills and experiences. The dependencies make it difficult to quantitatively evaluate current abilities in the eye-movement. This study aims to develop quantitative assessment indices for vision training which bases on quantitative data and have an equivalent ability of diagnosis by an optometrist. In order to use quantitative data, we measured eye movements with an eye-tracking system. Before the development, we implemented a method to realize re-calibration with a highly precise eye-tracking system while measuring simultaneous head and eye movements. We used the eye-tracking system to exploratory investigate the assessment indices for eye and head movements and then found out three assessment indices. Finally, we evaluated the effectiveness of the assessment indices by comparing the diagnosis results with these for each and an optometrist. We concluded that the assessment indices had a high potential to use the diagnosis.
