PROTÓTIPO HUET: AUTOMAÇÃO RESIDENCIAL UTILIZANDO LIBRAS

This work presents a home automation prototype, in the context of the Internet of Things, which stands out for being able to recognize some Signs of Libras to activate equipment. The name of the prototype is Huet, in honor of the Frenchman Ernest Huet, who educated and encouraged deaf students to learn sign language in Brazil. The prototype is in its initial phase, consisting of a central node (a low-cost microcomputer, Rasberry Pi) that performs the processing of images captured in a decentralized way by several ESP32-CAM microcontrolled platforms, which can be distributed throughout the house. When identifying a certain pre-programmed Libras sign, the central node sends a message via WiFi to another microcontroller that activates/deactivates a relay, allowing to turn on or off a lamp or a fan, etc. The results show the general functioning of the Huet prototype with the use of a parallel switch, performing the analysis of time and the number of correct identification of the symbols. In addition, this work contributes to the deaf community, through technology, allowing to break the communication barriers of this community with society.
