Abstract
In Brazil, according to IBGE (Instituto Brasileiro de Geografia e Estatística), 28.6% of the population has some deficiency. Among these, the visual impairment has the biggest representation, about 14.2% of Brazilians. Their locomotion through the streets of the Brazilian capitals has been an obstacle, mostly due to their lack in special location. To mitigate this problem, a project was developed to assist the visually impaired improving their circulation, based on computational methods and ultrasonic sensors. The developed algorithm is capable of performing distance measurements based on ultrasonic waves with a high level of reliability for distances until 1.6 m. This signal is then transmitted to micro-motors that are equally spaced in a belt around the person. They then start to vibrate in the object direction with intensity proportional to the object distance, allowing an excellent alternative to improve visually impaired people’s life.
