“…They are widely used in non-invasive BCI system because of its simplicity, inexpensiveness and high temporal resolution (Kayikcioglu & Aydemir, 2010;Zavala-Fernández, Orglmeister, Trahms, & Sander, 2012). Usually, the BCI system can be utilized to restore the motor functions or to offer mobility for the motor disabled individuals by using a BCI controlled device, such as the motorized wheelchairs or service robots (Rebsamen et al, 2006;Ron-Angevin, Velasco-Alvarez, Sancha-Ros, & da Silva-Sauer, 2011;Velasco-Álvarez, RonAngevin, da Silva-Sauer, & Sancha-Ros, 2013).
