Steady-State Visual Evoked Potential (SSVEP) in a New Paradigm Containing Dynamic Fixation Points
文献摘要：
Steady-state visual evoked potential(SSVEP) has become a powerful tool for Brain Com-puter Interface (BCI) because of its high signal-to-noise ratio,high information transmission rate,and minimal user training.At present,the edge information of each region cannot be identified in spatial coding based on SSVEP-BCI technology,and the user expe-rience is poor.To solve this problem,this paper de-signed a new paradigm to explore the relationship be-tween the fixation point position of continuous slid-ing and the correlation coefficient ratio in the dual-frequency case.Firstly,the standard sinusoidal sig-nal was employed to simulate the Electroencephalo-gram (EEG) signal,which verified the reliability of characterizing the amplitude variation of test signal by correlation coefficient.Then,the relationship between the amplitude response of SSVEP and the distance be-tween the fixation point and the stimulus in the hor-izontal direction was tested by Canonical Correlation Analysis (CCA) and Filter bank CCA (FBCCA).Fi-nally,the experimental data were offline analyzed un-der the condition of continuous sliding of the fixation point.It is feasible and reasonable to detect the am-plitude change of frequency component in SSVEP by utilizing the spatial coding method in this paper to im-prove the extraction accuracy of spatial information.
