Brain Computer Interfaces through Eletroencefalogram

Being able to control a computational system with one's mind corresponds to an old wish among computational interface designers. In this talk we will present the brain signals aquisition process through eletroencefalograms, applied to brain-computer interfaces design. We will present how these interfaces work, their limitations and the different brain signal acquisitio methodsn that are commonly used in this type of application, aiming to motivate the use of eletroencefalograms as a control mechanism in computer interfaces.
