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
