Abstract：A brain computer interface (BCI) makes a pathway between the human brain and the ambient environment, making it possible to control external devices directly by brain. The experimental paradigm is an important aspect for the BCI research, through which the brain signal features required for the classification of the BCI are elicited. In recent years, numerous studies on experimental paradigms have been carried out to improve the performance of BCI. This article reviewed the current status of studies on experimental paradigms of the visual event-related potential based BCI, including paradigm configuration, pattern of stimulus presentation, stimulus type, language model, and hybrid BCI. The challenges and future directions were discussed as well.
