At this meeting 2016-05-25 - Meeting notes we received Daniel GIRARD who described us the dyslexia.
Daniel is a specialist of digital solutions designed to compensate “dys”-type problems. He worked for example on Dysvocal software (http://www.dyslogiciel.fr/) and on a USB key called usb-dys (http://swagassodys.wix.com/usb-dys). He also conducts training in that field. Daniel exposed to us issues and needs of affected people and possible solutions, notably for Mail2Voice. We then had a discussion. Here is a synthesis of the overall discussion.
Dyslexia (https://fr.wikipedia.org/wiki/Dyslexie, http://www.doctissimo.fr/html/sante/encyclopedie/sa_1280_dyslexie.htm) is a reading problem. It appears at the first stages of reading learning. It is potentially hereditary. It's a neuro-developmental issue appearing right away in the child development. This issue is generally diagnosed in primary school during reading learning and causes scholar difficulties frequently. About 10% of the population is affected.
To understand what this problem is, we must define how reading process operates normally: First, a visual function takes action. It aims to recognize graphs. It is then linked to a lexicon (dictonnary of known words and syllabs) in order to establish a link between graphs seen and known words/syllabs. From this appears the mental composition of words, phrases and the resulting comprehension. In a dyslexiaon situation, the link between what is seen and the lexicon doesn't work properly. It exist different levels of this problem. However, an affected person has a lexicon so oral communication works perfectly.
There are different categories of “dys”-type problems : visuo-spatial dyspraxia, dys-calculus, etc.
As a first note, it's important to know that currently no OS-wide solution exist in mainstream OSes.
Text is read by software such the text is understood orally or verbally. This is the best solution.
One must be able to :
Beyond these functions designed specifically for dyslexia, we also discussed about:
