OKN Viewer: nystagmus — プロフェッショナルな視眼性心因反応シミュレーション＆記録

Even in healthy people, nystagmus naturally occurs when watching moving scenery. This app reproduces that nystagmus on your smartphone screen and lets you record your eye movements with the front-facing camera — a simple tool to observe and experience nystagmus. By staring at the moving stripe pattern (bands) on the screen, you can easily observe optokinetic nystagmus (OKN). It can be used as a preview/review tool in medical, rehabilitation, and educational settings, and also answers the simple question: “What does nystagmus actually look like?” 【Main Features】 • Adjustable stripe width Change the width of the moving stripes intuitively with a slider. • Adjustable moving speed Freely set how fast the stripes move, from very slow to fast. • Customizable stripe color Choose colors that suit your preference and visibility to enhance the visual effect. • Record eye movements with the front camera Keep your gaze fixed on the screen and record your eye movements, then review them later. 【Recommended For】 • Those who want to deepen their understanding of nystagmus and optokinetic nystagmus (OKN): physicians, medical students, orthoptists, nurses, rehabilitation staff, and clinical laboratory technologists. • Teachers and instructors looking for an easy-to-use visual teaching material for classes, practical training, or lectures. • Science- and medicine-oriented students, as well as general users who are interested in visual effects and how the body reacts to them. • No advertisements Important Notice This app is designed as a tool for observing, learning about, and experiencing nystagmus and optokinetic nystagmus.
