Brain switch mode: an alternative to drive a brain-controlled wheelchair
Fernández-Rodríguez, Álvaro; Velasco-Álvarez, Francisco; Ron-Angevin, Ricardo (2017-10-04)To date, different control paradigms of low level navigation have been tested for brain-controlled wheelchairs, mainly divided into continuous or discrete control [1]. However, these paradigms have certain drawbacks such ... -
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
Ron-Angevin, Ricardo; Fernández-Rodríguez, Álvaro; Velasco-Álvarez, FranciscoRecently, 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 ... -
