Implementation of Kiosk-Type System Based on Gaze Tracking for Objective Visual Function Examination

To demonstrate that the near-point-of-convergence (npc) examination is performed subjectively, visual fixation and four-prism diopter (Δ) base-out (BO) examinations can be conducted with a kiosk-type objective method based on gaze tracking, compared existing method. Objective equipment was used to verify effectiveness. Fifteen adult men women in their 20s 30s (26.87 ± 3.31 years) acuity of 0.8 (logMAR: 0.1, Snellen: 20/25(6/7.5)) or higher (corrected vision case ametropia) underwent npc, fixation, 4 Δ BO followed by gaze-tracking-based Three were performed, comparative analysis conducted. The tracking extracting eye feature points, it judged ocular moved when movement 30 points at edge iris detected. In comparison between method, there no statistically significant differences examinations. Npc extensively subjective however, seems these objectively using Visual require high-examination proficiency because finely moving movements need observed, but more easily accurately combined symmetrical characteristics two test results are expected serve as basis for clinical practice.
