Evaluation of switch and continuous navigation paradigms to command a brain-controlled wheelchair Fernández-Rodríguez, Álvaro Velasco-Álvarez, Francisco Javier Bonnet-Save, Manon Ron-Angevin, Ricardo Interacción hombre-ordenador Interfaces de ordenadores A brain-computer interface (BCI) is a technology allowing patients with severe motor dysfunctions to use their electroencephalographic signals to create a communication channel to control devices. The objective of this paper is to study the feasibility of continuous and switch control modes for a brain-controlled wheelchair (BCW) using sensorimotor rhythms (SMR) modulated through a right-hand motor imagery task. Previous studies, which used a continuous navigation control with SMR, have reported the difficulty of maintaining the motor imagery task for a long time, especially for the forward command. The switch control has been presented as a proposal that may help to solve this issue since this task is only used temporary for either disabling or enabling the movement. Regarding the methodology, 10 of 15 able-bodied users, who had overcome the criterion of 30% error rate in the calibration phase, controlled the BCW using both paradigms. The navigation tasks consisted of a straight path divided in five sections: in three of them the users had to move forward, and in the other two the users had to maintain their position. 2025-01-13T07:57:20Z 2025-01-13T07:57:20Z 2018-06-28 journal article Fernández-Rodríguez Á, Velasco-Álvarez F, Bonnet-Save M and Ron-Angevin R (2018) Evaluation of Switch and Continuous Navigation Paradigms to Command a Brain-Controlled Wheelchair.
