    • BCI-Controlled Wheelchair; Audio-Cue Motor Imagery-Based Paradigm 

      Velasco-Álvarez, Francisco; Varona-Moya, Sergio; Blanca-Mena, Maria Jose; 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 

      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-Controlled Wheelchair Through Discrimination of Two Mental Tasks 

      Ron-Angevin, Ricardo; Fernández-Rodríguez, Álvaro; Velasco-Álvarez, Francisco
      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 ...
