Resumen
Las personas con discapacidad visual están sujetas a problemas de movilización sobre todo en sociedades donde la inclusión es muy poco o nada desarrollada, lo que usualmente provoca accidentes ocasionados por obstáculos ubicados en alturas superiores a la cintura, no detectadas por un bastón. El proyecto de titulación tiene como objetivo disminuir las posibilidades de accidentes del no vidente y asistir a sus familiares por medio de un dispositivo que permita la detección de obstáculos usando ultrasonido, brinda la opción de monitorear en tiempo real la ubicación del no vidente ante situaciones de emergencia y permitiendo también el envío de mensajes de estado ya que usa una aplicación basada en la telefonía celular desarrollada en app inventor. Usando la metodología PMI se desarrollaron todas las partes del proyecto y para medir la aceptación del producto a través de encuestas a las personas que asisten al centro educativo de discapacidad visual en la ciudad de Guayaquil. La funcionalidad del dispositivo se verificó mediante pruebas de cumplimiento de las partes del diseño propuesto obteniendo como resultado un prototipo de gafas basadas en tecnología arduino, con sensor ultrasónico que permite la detección temprana de obstáculos, además de geolocalización en tiempo real a través de la aplicación móvil, envió de mensajes de actualización de estados como ayuda y control adicional hacia los familiares del no vidente y envío de mensajes de alerta ante situaciones de emergencia, alcanzando todos los objetivos propuestos del proyecto.
People with visual disabilities has many troubles during their transit in the city as well as at interior environments especially in societies where inclusion is less or not developed at all. This situation usually causes accidents due to obstacles located in heights above the waist, that the baton is not able to detect. This project has as objective decrease the possibilities of accident for blind people and help his relatives using a device that allows obstacles detection using ultrasound, it has the option to monitoring in real time the location of the blind person under emergency situations, sends status messages with an application that uses the mobile network. The project was developed using PMI methodology and to measure the acceptance of such kind of device, a survey was done among people that attend the educational center for visual disability at Guayaquil. The operativity and feasibility of the device was probed running test protocols for all its parts and functions, giving as result a prototype of glasses with an ultrasound sensor that allows the early detection of obstacles, in addition to geolocation in real time, status messages can be notified through mobile network to help relatives to be in control and monitor the blind person, and also gives the possibility to send an emergency alert in extreme conditions attaining all the proposed objectives of the project.
