BCI-Based Navigation in Virtual and Real Environments
Velasco-Álvarez, Francisco Javier
; Ron-Angevin, Ricardo; López-Gordo, Miguel Ángel (Springer, 2013-06)
A Brain-Computer Interface (BCI) is a system that enables people to control an external device with their brain activity, without the need of any muscular activity. Researchers in the BCI field aim to develop applications ... -
BCI-Controlled Wheelchair; Audio-Cue Motor Imagery-Based Paradigm
Velasco-Álvarez, Francisco Javier; Varona-Moya, Sergio; Blanca-Mena, María José; Sancha-Ros, Salvador; Ron-Angevin, Ricardo (2014-10-22)
In this study we present a control paradigm that enables subjects to drive a real wheelchair using four navigation commands. The control is achieved through the discrimination of two mental tasks (relaxed state versus one ... -
Brain switch mode: an alternative to drive a brain-controlled wheelchair
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 Control of Smartphone Messaging Applications
Velasco-Álvarez, Francisco Javier; Fernández-Rodríguez, Álvaro; Ron-Angevin, Ricardo (IARIA, 2021-07)
This work-in-progress paper presents an implementation of a Brain-Computer Interface (BCI) system focused on the control of the most common messaging applications of a smartphone: WhatsApp, Telegram, e-mail and Short Message ... -
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 ... -
Control de una silla de ruedas a través de un sistema BCI basado en la discriminación de dos tareas mentales
Ron-Angevin, Ricardo; Velasco-Álvarez, Francisco Javier; Varona-Moya, Sergio; Vizcaíno-Martín, 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 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 ... -
Evaluation of visual parameters to control a visual ERP-BCI under single-trial classification
Fernández-Rodríguez, Álvaro; Ron-Angevin, Ricardo; Velasco-Álvarez, Francisco Javier; Diaz-Pineda, Jaime; Letouzé, Théodore; André, Jean-Marc[et al.] (2023)
A brain-computer interface (BCIs) based on event-related potentials (ERPs) is a technology that provides a communication channel between a device and a user through their brain activity. These systems could be used to ... -
Exploring the impact of stimulus transparency in ERP-BCI under RSVP.
Fernández-Rodríguez, Álvaro; Velasco-Álvarez, Francisco Javier; Alvarez, Chloé; Langin, Célia; Letouzé, Théodore; André, Jean-Marc; Ron-Angevin, Ricardo[et al.] (ACM Library Digital, 2024)
Rapid serial visual presentation (RSVP) is currently one of the most suitable paradigms for implementing a visual brain–computer interface based on event-related potentials (ERP-BCI) for patients with limited ocular ... -
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-Álvarez, 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 ... -
Propuesta de BCI basado en RSVP con número reducido de estímulos usando el modo de escritura T9.
Vizcaíno-Martín, Francisco Javier; Velasco-Álvarez, Francisco Javier; Fernández-Rodríguez, Álvaro; Ron-Angevin, Ricardo (Actas Congreso CASEIB 2023, 2023)
Se propone un sistema de comunicación para personas con severas deficiencias motoras, como pacientes afectados de esclerosis lateral amiotrófica, usando una interfaz cerebro computadora. El sistema se basa en el paradigma ... -
Switch mode to control a wheelchair through EEG signals
Ron-Angevin, Ricardo; Velasco-Álvarez, Francisco Javier; Fernández-Rodríguez, Álvaro (Springer, 2016)
This paper presents a switch strategy to control the movement of a Brain-Controlled Wheelchair. After the activation of a Motor Imagery task, an advance movement is started and kept until the same task stop it. This way, ... -
UMA-BCI speller, A P300-Based spelling tool
Velasco-Álvarez, Francisco Javier; Sancha-Ros, Salvador; García-Garaluz, Esther; Fernández-Rodríguez, Álvaro; Medina-Juliá, María Teresa; Ron-Angevin, Ricardo[et al.] (Gernot R. Müller-Putz, Jonas C. Ditz, Selina C. Wriessnegger, 2019)
The brain-computer interface research group of the University of Malaga (UMA-BCI) has developed a speller application based on the wellknown P300 potential which can be easily installed, configured and used. The application ... -
UMA-BCI SPELLER: plataforma de comunicación de fácil configuración basada en el BCI2000 P300 SPELLER
