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 ... -
Effect of Stimulus Size in a Visual ERP-Based BCI under RSVP
Fernández-Rodríguez, Álvaro; Darves-Bornoz, Aube; Velasco-Alvarez, Francisco Javier; Ron-Angevin, Ricardo (MPDI, 2022)
Rapid serial visual presentation (RSVP) is currently one of the most suitable paradigms for use with a visual brain–computer interface based on event-related potentials (ERP-BCI) by patients with a lack of ocular motility. ... -
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-Alvarez, Francisco Javier; 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 ... -
Posible efecto de interacción entre el paradigma de presentación y el conjunto de estímulos en un teclado virtual controlado a través de una interfaz cerebro-ordenador basada en P300
Fernández-Rodríguez, Álvaro; Medina-Juliá, María Teresa; Velasco-Alvarez, Francisco Javier; Ron-Angevin, Ricardo (2019-07-25)
Muchos trabajos en spellers basados en señal P300 visual han presentado estímulos novedosos que mejoraron el rendimiento utilizando el paradigma fila-columna (RCP). Sin embargo, la presentación visual serial rápida (RSVP) ... -
Preliminary results using a P300 brain-computer interface speller: a possible interaction effect between presentation paradigm and set of stimuli
Fernández-Rodríguez, Álvaro; Medina-Juliá, María Teresa; Velasco-Alvarez, Francisco Javier; Ron-Angevin, Ricardo (2019-06-18)
Several proposals to improve the performance controlling a P300-based BCI speller have been studied using the standard row-column presentation (RCP) par-adigm. However, this paradigm could not be suitable for those patients ... -
Proposals of Control Paradigms Applied to a Brain-Controlled Wheelchair
Several of the neurological diseases that human beings can result in severe disabilities. In some cases, people who suffer from such deficiencies lose any chance of communication with their environment, being the only ... -
Review of real brain-controlled wheelchairs
Fernández-Rodríguez, Álvaro; Velasco-Alvarez, Francisco Javier; Ron-Angevin, Ricardo (IOP Publishing, 2016-10-14)
