Abstract

The invention discloses a brain-computer interface communication method which comprises the following steps: displaying flickering stimulation and a space target arranged on the flickering stimulationaccording to a preset stimulation program; collecting an electroencephalogram signal generated by observing the space target, and performing frequency decoding and space decoding on the electroencephalogram signal so as to judge the observed specific flicker stimulation and the specific space target on the specific flicker stimulation; wherein the preset stimulation program is jointly compiled according to the frequency code and the space code. Compared with a machine interface communication method, the method has the advantages that extra modulation dimensions are introduced into the added space target, the communication bandwidth is effectively widened, and the communication rate is increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a brain-computer interface communication method and device, a computer-readable storage medium and a terminal. Background technique [0002] Brain-computer interface (BCI) technology refers to a way of communicating with the outside world directly by measuring EEG signals without relying on traditional physiological output modes. In the existing brain-computer interface technology, there are many different stimulation methods, such as screen stimulation, LED stimulation, etc.; the signals used for analysis mainly include: SSVEP signal, ERP signal (such as P300 signal), motor imagery signal, etc. . [0003] The SSVEP signal has the characteristics of high signal-to-noise ratio and strong correlation with the frequency of the stimulus signal, and is widely used in the research and design of brain-computer interface. Using SSVEP signals, applications such as controlling robo...
