Implementación de un prototipo de red inalámbrica con nodos descriptores por voz de entornos urbanos para personas no videntes con información de ubicación y acceso web.

Abstract

This project was developed to facilitate the inclusion of visually impaired individuals in the information and communication technology (ICT) sector in Riobamba. The initiative introduces a mobile device that operates via voice activation, enabling users to navigate through a menu to select their desired destination. The system then transmits data from a sending node to a receiving node, which activates at a predetermined distance to notify the user that they are nearing their destination. Upon arrival, the device provides a descriptive overview of the location, detailing its various characteristics. Hardware-wise, the device includes an Arduino Mega module, which facilitates connectivity with an Emic 2 audio synthesizer module. The user interface is equipped with a GPS module, a compass, a SIM module, and wired headphones. The software, developed in C++, orchestrates routines that ensure seamless communication between the hardware components for optimal functionality. The system leverages a wireless network infrastructure to deliver real-time information on location coordinates. The project employs descriptive and field research methodologies. Testing has shown that the device can search for data and receive information within approximately 2 seconds, with minimal errors in coordinate accuracy when navigating within the area. This technological solution significantly aids the mobility of visually impaired persons.
