Resumen

People with visual disabilities have the problem of their autonomous mobility between obstacles in the path. Thus, assistive technology can help neutralize or decrease this disability, consisting of portable and low-cost assistance elements for use by these visually impaired people. Therefore, in this paper the design and implementation of a help tool for blind people has been carried out using an Arduino-based microcontroller, with ultrasonic devices for obstacle detection and warning devices with various audible levels depending on the distance to the obstacle. In this way the blind person has the possibility of avoiding accidents by detecting obstructions before direct contact and improving their quality of life, with an practical element of easy use and low cost.
