OKNDrum: Optokinetic Drum

OKNDrum is the practical digital alternative to a physical optokinetic drum, designed to elicit Optokinetic Nystagmus (OKN) for clinical assessment. This Chrome extension replaces bulky hardware with a configurable, on-screen stimulus that supports neurological, ophthalmological, and otological evaluations.

Key features include seven scrolling speeds, red or black stripe colors, adjustable scroll direction and stripe size, plus an easy-to-hide menu and clear instructions. The project was developed with medical professionals and is intended as a supplementary tool; it is not a substitute for professional medical advice.
