OKN Viewer : Nystagmus — Simulation et enregistrement optokinétiques professionnels

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.
