Outline of Final Research Achievements

This study was conducted with a multifaceted approach, aiming to test visual function in complex environments. In eye movement measurements, an automatic analysis system for smooth eye movement in clinical settings was developed and evaluated, and the accuracy was improved. In addition, a 3D model of an underground mall was reconstructed and reproduced in a VR space, demonstrating the possibility of presenting a complex environment using an HMD. Furthermore, visual function was evaluated through a reading experiment with a restricted visual field and a visual acuity test in the peripheral visual field. In addition, a wide range of research results were obtained, including the construction of an eye model specific to Japanese people and the prediction of visual function from fundus images using AI.
