Ubuntu documentation is mostly in text form. Text alone is not accessible for dyslexics. Dyslexics are visual learners. They require visual cues to learn. The user documentation needs to be revised. To include images to be accessible to dyslexics who want to learn ubuntu.
Dyslexics percent of population range(3 to 20%)
Thus all cannot program without changing the documentation.
Text alone is unpleasant to look at and may have optical illusion qualities that slightly disrupt balance causing an icky feeling plus confusion. See below for related text effects.
Text is seen as a 3d object like a hammer. It can be rotated or reversed.
Reading letters takes extra work. When words match reality ' I named my hammer Frank' dyslexics are comfortable. When words are hard to put into images, they are hard to recall; this makes for confusion in class. The class feels like it is too fast to understand.
- instinctive visual processing
- if not taught techniques for reading, may be functionally illiterate
- slow reading speed
-without visual images finds it hard to learn
- spoken instructions may not be understood if fast
- reading follows a slow process:
>>text>read symbols ---translate to images ----
> to write or speak about the information. In the text.
>>image(functional visual model)------ translate to words then
> words to text. Or words to speech
- when the text had words which are not easy to translate into images, either dyslexics create a new image or they may be confused and not learn
- text may be seen in color, blurred,wavy, sparkly, vibrating especially when complementary colors near text
Dyslexia is not a sight disability; it is a symbol processing disability.
