Design of interfaces for Dyslexia and Dyscalculia Applications

Abstract: In the field of Human-Computer interaction, one of the decisive factors is the graphical interface; especially in applications in which the user has specific conditions that limit its operation and performance. This is the case of the Gabarato application, which facilitates the treatment of children diagnosed with dyslexia and dyscalculia who are cared for by Sinsoluka Center in Ecuador.During the development phase of the application, it was determined that there is a complexity to achieve specific usability interactions such as “ease of use”, “memorability” and “effectiveness”, especially with users who do not have the ability to operate peripherals of the application. computer and who present physical or cognitive difficulties to manipulate a conventional interface.Although in the preliminary studies the methodologies, standards, and protocols were met in the prototype tests; it was evident that the metrics used might not be effective; For this reason, the present work presents a proposal to measure usability interactions in children who present specific conditions; With these results, new versions of interfaces oriented to mobile devices were made.In this work, comparative data are analyzed that establish differences between the usability metrics with conventional users and users who present specific conditions or disabilities; Additionally, a discussion is offered regarding the elements that make up the interfaces and their relationship with usability heuristics and the fundamentals of human perception.
