A powerful empathy experience, with a clear scientific boundary.
The moving letter experience is designed to interrupt automatic word recognition so fluent readers can feel extra reading effort. It is not a simulation of what every dyslexic person sees, not a diagnostic test and not a medical claim.
Where the idea came from
The interaction is inspired by Victor Widell’s 2016 Dsxyliea experiment, a widely shared browser demonstration that rearranged internal letters while readers attempted to keep up. Super Dyslexia uses a related visual technique but changes the framing: the movement is an analogy for reading friction, not a literal picture of dyslexia.
What the interaction does
The experience uses Unicode aware word segmentation, controlled letter transposition, fixed word dimensions, a timed reading task and intensity controls. The unchanged paragraph remains available to assistive technology while the animated version is hidden from screen readers.
Accessibility controls
The automatic teaser does not run when the operating system requests reduced motion. The full experience starts only after a deliberate user action and can be paused. The text itself remains available without animation.
