Diseño y construcción del sistema de apoyo para personas con visión reducida – Sapvire

Abstract

People with some degree of visual limitation, regardless of their age, gender and socio-economic stratum, have difficulties in mobilizing in public spaces, using public transport, accessing health services and their educational, labor, cultural and social inclusion. Due to these situations, government entities such as the National Institute for the Blind (INCI), the ICT Ministry, mobile technology applications and specialized devices offer a solution to people with visual limitations or low vision. Among the population with limitations are the military who have been victims of attacks and attacks in the armed conflict, the devastating effects were the loss of some limb and / or obtaining some limitation.

In this degree project, a device based on the detection of nearby objects and obstacles was developed to help the movement of people with visual limitations, from low-cost software and hardware tools, integrated into a system that can offer the user agility, independence and protection. At the same time it serves as a guide and alert system in the presence of nearby objects that may interrupt your mobility. The prototype has different electronic elements such as the Arduino Nano V3.0 Atmega 328 card, an HC-SR04 ultrasound sensor and a buzzer, among others. The prototype methodology that was used in the development of this research was documentary and experimental, covering stages and activities of continuous improvement that helped guide the project to its operation. As a result, there is the design and construction of the system, taking into account that a low cost is projected in its manufacture, distribution, acquisition and maintenance. In addition, it is easy to use and attachable to a traditional cane
