Title:
BRAIN-COMPUTER INTERFACE CONTROL METHOD AND SYSTEM BASED ON TWO-BRAIN COUPLING FEATURE
Document Type and Number:
WIPO Patent Application WO/2024/093796
Kind Code:
A1
Abstract:
A brain-computer interface control method based on a two-brain coupling feature, comprising: in response to at least two subjects collaboratively performing a motion control task of a brain-computer interface, dividing synchronously acquired lead pair electroencephalographic data of the at least two subjects into electroencephalographic training data and electroencephalographic test data, wherein the motion control task comprises at least one motion mode; performing two-brain coupling feature extraction on the basis of the electroencephalographic training data, and performing data transformation on the basis of the extracted feature to obtain a feature matrix; inputting the feature matrix into a classifier model for training to obtain a classification model, performing motion mode classification on the electroencephalographic test data on the basis of the classification model to obtain a mode classification result, determining the motion mode completeness of the mode classification result, and obtaining the test classification accuracy according to the completeness determination result; and determining the effectiveness of collaborative brain-computer interface control on the basis of the test classification accuracy.
