Abstract

The invention relates to a visual drive method, control method and control system of a brain wave human-computer interface. In the visual drive method, a plurality of flickering light sources are displayed for user observation, and different phase codes are made for the flash time sequence of the flickering light sources by utilizing time delay; and the visual evoked potential of a user is triggered by the flash time sequence for subsequent control, and the purpose of increasing system use comfort is achieved.

Description

technical field

[0001] The present invention relates to a visual driving method, a control method and a control system of a man-machine interface, in particular to a visual driving method and a control system of an brainwave man-machine interface that is stable in flash sequence and can be easily viewed by users and can be quickly identified. method and control system. Background technique

[0002] Patients with amyotrophic lateral sclerosis (ALS), stroke, head injury, multiple sclerosis and muscular dystrophy are unable to express their wishes, communicate with others, convey emotions, act independently and Self-care, and has barriers to communication with the outside world; therefore, researchers in various countries are trying to develop communication technologies that do not rely on muscles and nerves. One of the feasible methods is to use brain electrical signals (EEG) to communicate ideas as users Such a technology is called Brain Computer Interface (BCI for short), a...
