Abstract:

The braincomputer interface system is a communication system through which information can be exchanged with the outside world to express ideas without the aid of peripheral nerves and muscles.In the past 20 years,P300 potential has been attracting much attention as a typical potential of the braincomputer interface system.Many researchers have proposed different paradigms for the P300based braincomputer interface system to improve the performance of the braincomputer interface system.On the basis of summary and induction,three kinds of widely used paradigms with superior performance are discussed in detail,and their performance are compared and summarized.In addition,the physical properties influencing the paradigms are analyzed.Finally,an overview of the trend of future braincomputer interface paradigms development is discussed.
