Effective 2-D cursor control system using hybrid SSVEP + P300 visual brain computer interface.

Abstract

Acursorcontrolsystembasedonbrain-computer interface (BCI) provides efficient computer access. These systems operate without any muscular activity from the user. ConventionalBCI-basedcursorcontrolsystemshaveseverallimitations. Therefore, hybrid SSVEP + P300 visual BCI (VBCI)-basedcursorcontrolisneeded to overcome these limitations. This paper explores the feasibility of using noninvasive hybrid SSVEP + P300 VBCI for cursor control as a universal form of computer access. The proposed cursor control system has a graphical user interface (GUI) design that simultaneously evokes both SSVEP and P300 signals in the human cortex. The performance metrics of the proposed system are compared with conventional SSVEP VBCI and P300 VBCI-based cursor control systems. The proposed hybrid SSVEP + P300 BCI-based cursor control system achieves a maximum accuracy of 97.51% with a 27.15 bit/min information transfer rate (ITR). The results proved that the proposed system performed more efficiently than other systems. The proposed system was tested in a noisy environment and found to be suitable for real-world applications.
