Audio-cued motor imagery-based brain–compute rinterface: Navigation through virtual and real environments Velasco-Álvarez, Francisco Javier Ron-Angevin, Ricardo Da Silva-Sauer, Leandro Sancha-Ros, Salvador Brain–computer interface(BCI) Navigation Asynchronous Motor imagery(MI) Mental tasks Auditory he aim of this work is to provide a navigation paradigm that could be used to control a wheelchair through a brain-computer interface (BCI). In such a case, it is desirable to control the system without a graphical interface so that it will be useful for people without gaze control. Thus, an audio-cued paradigm with several navigation commands is proposed. In order to reduce the probability of misclassification, the BCI operates with only two mental tasks: relaxed state versus imagination of right hand movements; the use of motor imagery for navigation control is not yet extended among the auditory BCIs. Two experiments are described: in the first one, users practice the switch from a graphical to an audio-cued interface with a virtual wheelchair; in the second one, they change from virtual to real environments. The obtained results support the use of the proposed interface to control a real wheelchair without the need of a screen to provide visual stimuli or feedback This work was partially supported by the Innovation, Science and Enterprise Council of the Junta de Andalucı´a (Spain), project P07-TIC-03310, the Spanish Ministry of Science and Innovation, project TEC 2011-26395 and by the European fund ERDF. 2024-09-27T11:14:38Z 2024-09-27T11:14:38Z 2013-02-13 journal article VoR https://hdl.handle.net/10630/33708 http://dx.doi.org/10.1016/j.neucom.2012.11.038 eng open access application/pdf Elseiver
