Previous issue date: 2014-10-29 / Propomos neste trabalho, um novo m?todo de organiza??o conceitual das ?reas que
envolvem a tecnologia assistiva, categorizando-as de forma l?gica e simples; al?m disso,
propomos tamb?m a implementa??o de uma interface baseada em eletrooculografia, capaz
de gerar comandos de alto-n?vel, para acionar dispositivos rob?ticos, computacionais e
eletromec?nicos. Para a valida??o da interface ocular, foi desenvolvido um circuito
eletr?nico associado a um programa computacional que capturou os sinais gerados pelos
movimentos dos olhos dos usu?rios, gerando comandos de alto n?vel, capazes de acionar uma
?rtese ativa e diversos outros sistemas eletromec?nicos. Os resultados mostraram que foi
poss?vel comandar sistemas eletromec?nicos diversos, atrav?s apenas dos movimentos dos
olhos. A interface apresentou-se como uma forma vi?vel para a executar das tarefas
propostas, podendo ser aprimorada no quesito de an?lise de sinais a n?vel digital. O modelo
diagram?tico desenvolvido, apresentou ser uma ferramenta de f?cil uso e entendimento,
suprindo as necessidades de organiza??o conceitual da ?rea de tecnologia assistiva. / We propose in this work, a new method of conceptual organization of areas involving
assistive technology, categorizing them in a logical and simple manner; Furthermore, we also
propose the implementation of an interface based on electroculography, able to generate
high-level commands, to trigger robotic, computer and electromechanical devices. To
validate the eye interface, was developed an electronic circuit associated with a computer
program that captured the signals generated by eye movements of users, generating
high-level commands, able to trigger an active bracing and many other electromechanical
systems. The results showed that it was possible to control many electromechanical systems
through only eye movements. The interface is presented as a viable way to perform the
proposed task and can be improved in the signals analysis in the the digital level. The
diagrammatic model developed, presented as a tool easy to use and understand, providing the
conceptual organization needs of assistive technology
