Attention is very important for learners,as it is closely related to EEG signals and can be improved through training.This paper proposes a training system based on mobile intelligent terminal application APP for EEG signal feedback,which includes two methods of training:Schulte Grid and arithmetic operation.During training,the attention state information of the trainee's EEG feedback can be viewed in real time,enhancing the training effect.The practical results show that there is a positive correlation between attention and EEG signals.Trainers can significantly improve their attention after long-term training,and training can also enhance their ability to quickly adjust their attention state.
