ABSTRACT
ObjectiveTo evaluate the effect of electroencephalography(EEG) recognition rate resulted by stimulus of visual, auditory and combined perception. MethodsIn virtual traffic environment, the stimuli were designed in traffic information based on visual, auditory and audio-visual fusion. When one of the three stimuli appeared, the subjects completed starting and braking vehicle by imaginary using of right and left hands at the same time. The EEG signals were recorded and the imaginary motion-related features from C3, C4 were extracted and classified. ResultsThe best recognition rates in visual, auditory and fusion perception were 100％, 100％and 83％, respectively, while the averages of the rates were 68.8％ 、82.2％、76.9％, respectively. Conclusion The recognition rates are affected by the audio, visual and fusion stimulus and apparent individual differences exist.
