DYSLEXIA SIMULATION
Many people know the word dyslexia, but few understand what reading actually feels like for someone who has it.
Victor Widell created this interactive simulation after a friend with dyslexia explained how letters seemed to jump, rotate, or slip out of place while she read. His simple JavaScript tool rapidly swaps letters inside words to mimic that sensation—not as a perfect representation, but as a glimpse into one of the many ways dyslexia can affect reading. Because every dyslexic brain works differently, no single simulation can capture every experience, yet many people recognize elements of their own challenges in this shifting text. With dyslexia affecting an estimated one in five people, tools like this help make the invisible visible, deepen understanding, and build a more inclusive world for all learners.
