Dyslexia mainly involves difficulty linking letters and sounds (phonological processing). Most dyslexic readers do not see letters moving or flipping. This is an empathy demo and approximation, not a diagnosis or a medical tool. See the International Dyslexia Association definition.

Frequently asked questions

Can teachers use this in a classroom?

Use it to discuss patience, accessible materials and individual experiences. Explain that this is not what dyslexia looks like for most people. Be sensitive to dyslexic students in the room: participation should be optional, and nobody should be asked to disclose a diagnosis or perform publicly.

Does this show what dyslexia feels like for everyone?

No. Moving letters and a symbol puzzle cannot reproduce another person’s experience. Ask readers about their own preferences and avoid drawing conclusions about anyone’s reading ability.
