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

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.
