Dyslexia is a learning disability that affects 3-7% of the population, and up to 20% may have some degree of the symptoms. It is not an intelligence problem, but considered a cognitive disorder that primarily affects learning, memory, perception, and problem solving. Specifically, it impairs a person’s ability to read. As web designers, we need to be aware of the design choices we make so we don’t make it harder for people with dyslexia to read a website.
Dyslexia Design Decisions
When making design choices we need to consider the needs of the following two groups:
Dyslexic people who use computer speech output technology: Like many visually-impaired users, many dyslexics now rely on computers to read the text to them. Thus pages should be designed to be compatible with most screen readers. All important information should be conveyed in text, as computers can not read or interpret graphic images.
Dyslexics who need clear graphics and distortion-free text: Other dyslexic individuals, who are reading your site on their own, will appreciate clear, simple, and consistent graphic navigational icons. They will be troubled by flashing text, variations in fonts, distracting sounds or animations, and textured or patterned backgrounds.
