Um grupo de cientistas do Georgia Institute of Technology, nos Estados Unidos, apresentou um dispositivo que permite a deficientes f\u00edsicos controlar uma cadeira de rodas ou operar o computador mexendo apenas a l\u00edngua.<\/div>\n
Chamado de Tongue Drive (Impulso da L\u00edngua), o aparelho \u00e9 um im\u00e3 do tamanho de um gr\u00e3o de arroz que deve ser colocado na ponta da l\u00edngua dos pacientes e “substituiria” o cursor do mouse de um computador ou o joystick que controla os movimentos das cadeiras de rodas el\u00e9tricas.<\/div>\n
O movimento do dispositivo magn\u00e9tico \u00e9 detectado por sensores, que podem ser acoplados a um capacete ou a um aparelho ortod\u00f4ntico bucal. Eles s\u00e3o respons\u00e1veis por transmitir os sinais para um computador port\u00e1til que pode ser carregado na roupa ou na cadeira de rodas do usu\u00e1rio.<\/div>\n
Segundo o professor Maysam Ghovanloo, que desenvolveu o dispositivo ao lado do aluno Xueliang Huo, a l\u00edngua foi escolhida porque n\u00e3o \u00e9 controlada pelo c\u00e9rebro por meio da medula espinhal — danificada nos parapl\u00e9gicos.<\/div>\n
“A l\u00edngua \u00e9 diretamente conectada ao c\u00e9rebro por um nervo cranial que geralmente escapa dos danos causados em ferimentos na medula e das doen\u00e7as neuromusculares”, diz Ghovanloo. “Al\u00e9m disso, os movimentos da l\u00edngua s\u00e3o r\u00e1pidos, precisos e n\u00e3o requerem muita aten\u00e7\u00e3o, concentra\u00e7\u00e3o ou esfor\u00e7o”, explica ele.<\/div>\n
Avan\u00e7o<\/strong><\/div>\n
A equipe de pesquisadores realizou testes do aparelho com 18 pessoas saud\u00e1veis, que operaram o mouse do computador e uma cadeira de rodas el\u00e9trica apenas com o movimento da l\u00edngua.<\/div>\n
No teste com os computadores, os participantes testaram seis comandos diferentes que substituiriam o clique e o movimento do mouse –esquerda, direita, para cima, para baixo, clique \u00fanico e dois cliques.<\/div>\n
De acordo com os resultados, a resposta do computador para os comandos dados pela l\u00edngua foram realizadas em menos de um segundo e os participantes tiveram quase 100% de precis\u00e3o nos comandos.<\/div>\n
Um grupo de comandos especial pode tamb\u00e9m ser desenvolvido para se adaptar \u00e0s habilidades e necessidades dos pacientes.<\/div>\n
“A pessoa pode potencialmente treinar nosso sistema para reconhecer o toque em dentes diferentes como comandos diferentes”, explica o cientista.<\/div>\n
Os cientistas apresentaram o novo dispositivo durante um encontro da Sociedade Americana de Engenharia da Reabilita\u00e7\u00e3o e Tecnologia Assistiva, em Washington, nos Estados Unidos.<\/div>\n
A equipe ressaltou que, ao contr\u00e1rio de outros dispositivos, o novo aparelho \u00e9 n\u00e3o-invasivo e seu implante n\u00e3o requer cirurgias complicadas no c\u00e9rebro.<\/div>\n
O pr\u00f3ximo passo ser\u00e1 testar o dispositivo em pacientes com defici\u00eancias graves.<\/div>\n
“Esse dispositivo pode revolucionar o campo da tecnologia assistiva ao ajudar indiv\u00edduos que sofrem de defici\u00eancias s\u00e9rias, como aqueles que sofreram danos graves na medula espinhal, a ter uma vida mais independente, ativa e produtiva”, afirmou Ghovanloo.<\/div>\n
