Desarrollo de dos aplicaciones accesibles para personas con discapacidad intelectual para INSFIDIM

Abstract

The present integrative project was carried out in conjunction with the communication and language therapists of the Motor Disability Fiscal Institute. The students of this institute mostly have intellectual disabilities. The therapists give specialized classes to each of their students to help them with their education, for which they require personalized tools that help in the learning.

The objective of this project is to develop two accessible applications for people with intellectual disabilities for the Motor Disability Fiscal Institute.

For the development of the applications, User Experience was used in conjunction with the Prototyping paradigm. The plans used in User Experience are: strategy, scope, structure, skeleton and surface. Three prototypes of the applications were developed: low fidelity, medium and high fidelity. Each prototype was evaluated, in the last prototype we used the happiness and task success categories of Heart (Google), and Mobile App Rating Scale.

Tasks success and the satisfaction survey show that the therapists made it easy for them to understand and use the applications. In addition, they show appreciation for the general design of the applications. The score obtained in the Mobile App Rating Scale was 4.51 out of 5, which means that it has an acceptable quality.

User Experience and Prototyping in conjunction with Mobile App Rating Scale and Web Content Accessibility Guidelines 2.1, allowed to verify that the applications have a good design, understandable navigability, correct functionalities, is easy to use, and above all that, they fulfill their purpose, the which are: therapist data management, student, sequence of actions and alternative communication, and assist in the learning of sequence of actions and alternative communication through the use of games.
