Ron-Angevin, Ricardo; Velasco-Alvarez, Francisco; Varona-Moya, Sergio; Vizcaino-Martin, Francisco Javier; Díaz-Estrella, Antonio (2014-07-22)En este trabajo se presenta una propuesta de control de una silla de ruedas a través de una interfaz cerebro computadora mediante la discriminación de sólo dos tareas mentales. Con el paradigma de control propuesto se ... -
Estudio preliminar de la usabilidad de tres tamaños de teclados basados en Interfaces Cerebro-Computador por pacientes con ELA
Medina-Juliá, María Teresa; Fernández-Rodríguez, Álvaro; Velasco-Álvarez, Francisco; Ron-Angevin, Ricardo (2019-07-25)En referencia a los teclados basados en Interfaces Cerebro Computador que utilizan el biopotencial P300 como señal de control, el tamaño óptimo para personas con discapacidad motora no se ha presentado propiamente. En este ... -
Exploring a P300 Brain-Computer Interface Based on Three Different RSVP Paradigms
Ron-Angevin, Ricardo; Abadie, Maëlle; Cloarec, Maëlle; Filosa, Martin; Jouault, Maurine; [et al.] (Birgit Gersbeck-Schierholz, Leibniz Universität Hannover, Germany, 2019-06)A BCI Speller is a typical Brain-Computer Interface (BCI) system for communication purpose. This technology can provide users with severe motor disability with an assistive device controlled by brain activity. In the present ... -
