Visual stimuli for the P300 brain–computer interface: A comparison of white/gray and green/blue flicker matrices

An efficient word typing P300-BCI system using a modified T9 interface and random forest classifier

“…Multiple attempts have been made to modify the Farwell and Donchin (FD) paradigm. These modifications include using different matrix sizes [2], changing visual aspects such as color, symbol dimensions, and distance between the symbols [3,4], single character flipping instead of row and column intensification [5], and using a checkerboard paradigm [6]. Some works suggested the potential of region-based [7] or submatrixbased [8] paradigms.…”

Communication Impairment in ALS Patients Assessment and Treatment

“…The computer identifies the attended item as the intersection of the row and column that elicited the largest P300. The RCP has been tested in various configurations to achieve efficient communication that is practical for in-home use Lenhardt et al, 2008;; the paradigm itself has been modified (Guger et al, 2009;Hong et al, 2009;Martens et al, 2009;Salvaris & Sepulveda, 2009;Takano et al, 2009). Unfortunately, none of such alternative paradigms substantially improves P300-based BCI performance.…”

Tensor classification for P300-based brain computer interface

“…One is to optimize stimulator by changing its stimuli or the paradigm. Takano et al used green/blue flicker [4]. Hoffmann et al applied images such as radio, lamp, TV and so on as a flash by changing its brightness [5].…”
