Brain-computer interface for communication and control purpose
Ron-Angevin, Ricardo; André, Jean-Marc (International Science and Technology Conference Institute (ISTIC), 2022)Brain-computer interfaces (BCI) are a type of assistive technology (AT) that uses the brain signals of users to establish a communication and control channel between them and an external device (usually a computer). BCI ... -
Brain-Computer Interface: comparison of two control modes to drive a virtual robot
Ron-Angevin, Ricardo; Debeyre, Aurélie; Marquet, Yvan; Lespinet-Najib, Véronique; André, Jean-Marc (2015-10-02)A Brain-Computer Interface (BCI) is a system that enables communication and control that is not based on muscular movements, but on brain activity. Some of these systems are based on discrimination of different mental ... -
Brain-Controlled Wheelchair Through Discrimination of Two Mental Tasks
Recently, Brain-Computer Interface (BCI) research has been targeted at the rehabilitation of motor-disabled individuals because it helps to establish a communication and control channel for them. This new channel could ... -
