Desarrollo de una aplicación móvil de información turística utilizando códigos QR para personas con discapacidad visual.

Abstract

The main objective of this curriculum integration work was the development of the mobile application "GREIVAG" for devices with Android operating system, facilitating access to tourist information for visually impaired people, through the use of QR codes and audios, for the tourist agency "Greivag Travel & Adventure". We analyzed the application accessibility issues faced by the visually impaired people. Subsequently, we reviewed studies with similar themes to better guide the development of the application, as well as a review of the technologies and tools that were utilized. Finally, it was decided to build the system separating it into two applications, a mobile application developed with the Flutter framework for users and a web application developed with the Angular framework for the administrator, these in turn communicate with the MySQL database using Spring Boot for data management and the creation of APIs that allow the system to communicate between the different components developed. A Model-View-Controller design pattern was utilized to structure the system and we selected to use the agile XP (External Programming) methodology to maintain an orderly workflow. The mobile application was evaluated under the Web Content Accessibility Guidelines (WCAG), obtaining an 80% of satisfaction degree. Utilizing the Tukey test with a 90% confidence level and a 10% margin of error, the equality of means of the Accessibility criteria groups was determined. It is concluded that the "GREIVAG" application is accessible to be used by visually impaired people. It is recommended the development of a web page that consumes the APIs, thus achieving to show the information of the tourist attractions in new platforms.
