Experiment Materials and Methods : Thirteen right-handed health subjects aged between 19 and 24 years participated in the study. All subjects had normal or corrected vision and did not have any history of neurological disease. This project was approved by the university’s ethics committee. Before the experiment, subjects were required to sign an informed consent and all were paid 100-Yuan after the experiment. During the experiment, subject was required to sit still for 1 minute and then stand up and keep standing for 1 minute and then sitting down again, and these actions are completed repeatedly and alternately, as shown in Fig.2. EEG signals were recorded during the whole process and each subject finished 6 sessions which takes about 10 min and 1 min break after. Subjects were required to keep quiet during the experiment, especially when they sitting down and stand up, to minimize other movement artifact.
