A New SSVEP Brain-computer Interface Based on a Head Up Display

摘要：

　　In this paper,we propose a new Steady State Visual Evoked Potential (SSVEP)-based brain-computer interface (BCI) with the visual stimuli displayed on the windshield via a Head Up Display system.Two chessboardimages flickering at specific frequencies and representing different commands were developed as SSVEP stimuli.A linear discriminant analysis classifier was used to recognize the different patterns and output thecorrespondingcommands.Experimental results from three healthy participants with no subject screening being conducted indicate that the average accuracy of the new BCI system is close to 80% with the window length of 4 seconds and step size of 0.25 second,showing that the proposed BCI system is feasible.The potential benefit of this system is that it little obstructs users to look at surroundings while applied to drive a vehicle.
