Protótipo de teste utilizando sinais oculares para auxiliar na mobilidade de pessoas com tetraplegia.

Abstract

This research proposes the development of a prototype, technological equipment using electro-oncographic (EOG) to assist on the mobility of quadriplegic people, in addition to other disabilities that affect motor mobility. The system is divided in four main steps: 1) The first corresponding to the EOG signal module; 2) the second related to the signal processing module, where it'll be propared to be digitized; 3) on the third step the signal is received by a microcontroller, where a feature extraction will be performed, and thus made a signal classification; 4) on the fourth and last step, it is performed control of the object and its movement through commands by eye movement. For a initial study it is proposed the development of a interface that consists in a signal acquisition board, as well as a toy cara, simulating a wheelchair, where the user must move the chair using specific eye movements until it reaches their objective. The proposal will be evaluated by couting the number of errors and the time it will take the user to complete the task. All tests carried out in the laboratory in strictc way, only for colleages present there, so that tests on the target audience (quadriplegic people) were not possible, which would be ideal. The results show that the product works and that the technology proposed is efficient.
