Computer Aided Diagnostics of Developmental Dyslexia

Abstract

Dyslexia is the subject of many studies. One of the reasons for this phenomenon may be the increasing percentage of society with diagnosed problems of specific learning difficulties (current-ly about 10% of pupils have diagnosed dyslexia; Brejnak, 2003). School teachers, with limited time and money, are often unable to diagnose all students with learning disabilities. The proposed system, which is a free alternative to commercially available solutions, was implemented in two primary schools, where it was positively evaluated by school counselors. The accuracy of the individual modules of the system oscillated around 80%, the specificity was 90–100%, and the sensitivity ranged between 60 and 70%.
