Desarrollo de una aplicación móvil para la obtención de información auditiva desde una base de datos relacional, empleando etiquetas NFC con Android.

Abstract

The present titling work was carried out with the objective of developing a mobile application in the Android operating system to obtain auditory information by means of a smartphone, with near field communication technology (NFC), in order that people with visual or partial disability have the possibility of accessing to buy in a supermarket and be able to purchase their products for personal consumption with intention of minimizing time and search facilitating. It was necessary to develop a web service prototype implemented with the object access protocol (SOAP) to simulate a super-data system and consume data from the mobile application, also using SQLite, a relational database management system, was used for the internal storage of data Smartphones and NFC technology, to exchange data between two devices wirelessly, which add NFC NTAG tags and save characteristics of the product by means of a code. The development of the mobile application called "AudiGo" was carried out using the agil methodology for SCRUM software development. For the experimentation of DECSEDIV-FENCE Project in APRODVICH with its collaboration installs were needed, located in Riobamba, where the time people with visual disabilities used to buy a product, was determined; 33 people were divided into two groups, the first group was the experimental, by using the application of another control that carried out the action on a daily basis. The results obtained when using the application or not were compared and determined with a certainty of 95%, that the time that blind people use when using the mobile application was different than the time obtained without its use, due to this, it is concluded that the mobile application is an aid for people with visual disability, besides that, it allows inclusion and improvement of people life quality.
