Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0024] refer to figure 1 , the control system 100 of the electroencephalogram human-machine interface in the preferred embodiment of the present invention is used to control a peripheral device 2, the control system 100 has a flash device 11, a measuring device 12, a computing device 13, an identification device 14, a A control device 15 and a template database 16 .

[0025] The flash device 11 has a programmable chip 110 and a plurality of flashing light sources 111-118 for a user 5 to watch. The flashing timing of each flashing light source 111-118 is to use the programmable chip 110 to control the time delay to achieve different phase encoding. .

[0026] The phase encoding principle adopted by the visual driving method of the brainwave man-machine interface of the present invention is: the phase angle (θ) in a sine wave mathematical formula S (t)=sin (ωt+θ...

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...
