Luva inteligente converte língua de sinais em fala por meio de app


Especialistas da Universidade da Califórnia (UCLA) criaram uma luva de alta tecnologia capaz de converter, em questões de segundos, a Língua Americana de Sinais (ASL) em fala, por meio de um aplicativo para smartphone.

O sistema inclui um par de luvas com sensores finos e elásticos que envolvem todos os dedos. Por meio de fios elétricos embutidos nos sensores, o aparelho detecta os movimentos que representam letras, frases e números. 

Os gestos então são transformados em sinais elétricos, que são enviados a um circuito localizado no pulso e depois transmitidos a um smartphone, responsável por transformá-los em palavras faladas em um ritmo de uma palavra por segundo. 

Esta não é a primeira invenção do tipo, contudo, os sistemas produzidos até então eram pesados e desconfortáveis. Segundo os especialistas da UCLA, sua criação é leve, barata e duradoura.

 

Resultados dos testes

Os pesquisadores treinaram a luva e o app que a acompanha com quatro usuários surdos. Os participantes repetiram cada gesto manual por 15 vezes e um algoritmo personalizado de aprendizado de máquina transformou esses gestos em letras, números e palavras.

Além disso, os cientistas testaram colar sensores adesivos nos rostos dos usuários, em uma tentativa de capturar as expressões faciais que ajudam a compôr a linguagem de sinais norte-americana.

No total, o sistema aprendeu a reconhecer 660 sinais, incluindo cada letra do alfabeto e os números de zero a nove. Agora, a equipe planeja comercializar a tecnologia patenteada, se puderem acelerar ainda mais o tempo de tradução.

"Nossa esperança é que isso abra um caminho fácil para as pessoas que usam a linguagem de sinais se comunicarem diretamente com quem não usa, sem precisar de outra pessoa para tradução", disse o professor Jun Chen, da UCLA. "Além disso, esperamos que isso ajude mais pessoas a aprenderem a linguagem de sinais".
