The invention discloses an electroencephalogram head ring
interaction control method and device based on concentration level, and the method comprises the steps: collecting multi-band electroencephalogram signals and user interaction parameters, carrying out spectrum decoupling analysis to recognize a concentration feature baseline, exporting an attention
stability coefficient, and building a cognitive state mapping relation; tracking a high-
response frequency band core to implement
frequency band fusion analysis to form a
control channel, and collecting concentration fluctuation data to construct an
interaction control network; executing multi-task
response analysis to identify an intention switching point, extracting
cognitive load parameters to divide a low-load area and a high-load area, and extracting a
recovery rate to construct an attention
toughness index in an identification conversion process; determining an optimal trigger position in a low-load area according to an attention
toughness index, constructing a brain wave feature chain, aligning the brain wave feature chain with an attention
stability coefficient, determining a low-interference response window, and setting a self-adaptive threshold group; and the
coupling identification false triggering area extracts redundant brain wave components to execute false triggering suppression to generate an
interaction control instruction, so that accurate matching between teaching intervention and the cognitive state of the student is realized.
