Interactive System to Improve the Skills of Children with Dyslexia: A Preliminary Study

This paper describes a virtual system for the strengthening of linguistic abilities of children with dyslexia. To achieve this objective, an intuitive interface has been developed. The interface consists of three games (each with three levels of difficulty), all of them being part of a rehabilitation program. These applications combine visual and auditory messages that complement each other, in order to provide an immersive experience and to train more than one of the five senses at a time. The virtual environment has been developed in Unity 3D software, and the diffusion of sounds is performed through binaural hearing aids. To evaluate the performance of the presented proposal, a sample of eight infants (three girls and five boys) with ages between 8 and 12 years was chosen. As an inclusion criterion, it is determined that the user must have an age greater than 7 and less than 13 years, and as a criterion of exclusion the presence of some visual impairment and/or an auditory disorder or other disorder that affect the educational environment. It must be taken into account that this is a preliminary study and that the experimental results in the patients will be seen in the long term. Therefore, to evaluate the acceptance of the system, and to make future corrections a SUS usability test has been applied, with the following result (82.5 ± 0.52). At the end of the execution of the applications, a report is issued in which the specialist can control how the patient has progressed during sessions.
