Desarrollo de una aplicación web del tipo “Tienda Digital” enfocada a personas con limitaciones visuales.

Abstract

The objective of the present degree work was to develop a web application of the “digital store” type focused on people with visual limitations within Ecuador, where the search and purchase of different types of digital products are facilitated. The methodology used for the development of the web application was SCRUM, applying the 3 established phases: planning phase, development phase, and completion phase. In the planning phase, the functional requirements of the system were defined, which were documented using the use case diagrams. In the development phase, a total of 19 sprints were carried out, through the use of development tools such as PostgreSQL as the database engine, Java as the programming language, JavaScript allowing the development of a dynamic and interactive interface with the user in a set with HTML and CSS, as well as Netbeans as an integrated development environment. Finally, system management was examined with the BurnDown Chart tool. The evaluation of the web application was carried out in accordance with the ISO / IEC 25010 standard in conjunction with the SIRIUS tool. The criteria to be evaluated were accessibility and ease of use, which, in turn, are part of "Usability" as a quality characteristic of a software product. The results obtained show a usability percentage of 82.51% in people with visual limitations and 83.32% in people without visual limitations, which is valued as very good and acceptable in both groups of people. In conclusion, the web application developed is in correspondence and compliance with the objectives set, therefore, this work is recommended as a reference for future research.
