ABSTRACT
Mobility for people with visual impairments is a challenge in places
where there is no knowledge of obstacles. Research carried out in
this work identified that people with visual impairment have difficulties
with obstacles located above 1 meter. Thus, an approach is
proposed to notify the visually impaired person through sound and
vibration about such obstacles. The proposed solution is available on
the ThingSpeak platform and components such as microcontrollers
(ESP8266 NodeMcu ESP-12), sensors, buzzer and GPS were used
in its development. Results confirmed that the proposed approach
correctly identified the existence of obstacles with a height equal
to or greater than 1 (one) meter in the way of visually impaired
people.
