Desenvolvimento de uma Arquitetura Baseada na Internet das Coisas para uma Bengala Eletrônica Baseada no Contexto das Cidades Inteligentes

This paper describes an architecture based on the Internet ofThings (IoT) for the electronic cane project. It was designed toassist the locomotion process of visually impaired individuals inthe context of smart cities. The architecture allows, through amicrocontroller and a GPS module embedded in the cane, toregister and subsequently identify obstacles according thegeographic coordinates. A smartphone was used to transmit andstore this information in the cloud for further processing. Theinteraction of the cane with the smartphone will open a futurerange of applications, such as the identification of points ofinterest, detecting the proximity of other users of the electroniccane, among other uses. The functionality tests were satisfactory,with an accuracy of 80% identifying the recorded obstacles.
