说明：  通过计算得到脑电专注度实时采集信息，设计了GUI 界面，按下采集按钮开始采集脑电信号，实时显示专注度值，通过虚拟键盘显示对应专注度范围
(The GUI interface was designed. The EEG signal was collected by pressing the acquisition button. The concentration value was displayed in real time, and the corresponding concentration range was displayed by virtual keyboard)
