Desenvolvimento de um detector de obstáculos de baixo custo para deficientes visuais

Abstract

We live in an increasingly technological world, in this scenario it is extremely important to use the resources we have at our disposal to provide greater inclusion and quality of life for people with disabilities. Therefore, this work presents the study for the development of a low-cost device to aid the mobility of the visually impaired, using notions of microcontrolled systems and electronics. The device has three sensors, which detect obstacles, two actuators, which emit audible and tactile warnings to the visually impaired, and a battery, responsible for supplying the microcontroller, which controls the system and supplies the sensors and actuators. Several tests were carried out with the prototype built, simulating obstacles faced by the visually impaired in their daily mobility, although its operation has been validated, the need for certain improvements is evident, mainly related to the physical and hardware structure.
