Abstract

The invention provides a two-person cooperative P300-BCI target decision-making system and method. The two-person cooperative P300-BCI target decision-making system comprises a brain-computer interface, a task recognition mechanism and a data processing system. The brain-computer interface is connected with the task recognition mechanism, the data processing system is connected with the task recognition mechanism, the brain-computer interface can receive electroencephalogram information of two testees. Each testee correspondingly identifies whether a to-be-identified task appears on a row coordinate or a column coordinate of the N * N two-dimensional RC normal form interface screen, and the data processing system comprises a normal form test system and a testee electroencephalogram signaldata processing module, so that the row coordinate or the column coordinate of the to-be-identified task identified by each testee can be known; and identification results are obtained. Decision is optimized in a brain-computer interface two-person collaborative decision mode, so that the recognition efficiency is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence brain science and computer technology, in particular to a P300-BCI target decision-making system and method in which two people cooperate. Background technique [0002] Brain computer interface (brain computer interface, BCI), also known as "brain port" or "brain-computer fusion perception", aims to establish a connection path between people and external devices. In the experiment, when the subjects received external When visual stimulation occurs, the internal neural activity of the brain will undergo corresponding changes, and these passive responses will form different EEG spatiotemporal scale patterns. Using computers to collect and analyze EEG signals, the corresponding stimulation signals will be be identified and judged.Through the analysis of these stimulation signals, they can be used as instructions for people to control external equipment, so as to realize the identification of sp...
