Implementación de un prototipo de gafas y bastón electrónico creando una red inalámbrica de comunicación y alerta para personas con discapacidad visual.

Abstract

Due to the current situation presented the blind people and the restrictions that systems with similar characteristics have, a prototype of glasses and electronic stick was implemented creating a wireless communication and alert network (BGE) for people with visual disabilities. The prototype together allows to detect obstacles by vibrations and to send an alert message when an emergency arises, it is composed of three modules: the actuator module that integrates to white cane, contains an ultrasonic sensor for lower frontal obstacle, it is also used an Arduino Nano. The receiver module consists of three ultrasonic sensors that integrate glasses, depending on the distance to which the obstacle is located with respect to the sensor, the speed of the motor increases or decreases respectively. Finally you get the alert module, it allows to send a help message to the contact number previously selected and then a message with the address of its location coordinates. Of the tests carried out, it was determined that the system presents an error of 5% in distance measurements and a variability of 0.98% which determines that the prototype is stable. When evaluating the implementation cost, it is determine that it is 60% less than similar commercial systems. It is recommended to reduce the size of the prototype and incorporate it into a spectacle structure, establish a hearing system for battery discharge or study the possibility that the type of feeding is self-sustaining.
