摘　　要：The electroencephalogram（EEG）characters value of observers can be deduced by collecting brain electrical information when the observers are watching parallax stereo video.The characters value will change clearly when watching asthenopia appear.To investigate the characters of parallax stereo watching asthenopia,the EEG of observers were recorded through the whole watching process of parallax stereo films until watching asthenopia appeared.The recorded EEG data of observers belongs to time-domain information.Fourier transform can process these data to frequency spectrum information.Theαandβwaves average power can be got by Newton-Cotes equation from the information.The ratio ofβpower to the sum ofαandβpower,CV,can be defined as EEG characters value of parallax stereo watching asthenopia and used to estimate the asthenopia degree of observers.Our experiments show that the smaller the CVis,the more serious the asthenopia is.The electroencephalogram（EEG）characters value of observers can be deduced by collecting brain electrical information when the observers are watching parallax stereo video.The characters value will change clearly when watching asthenopia appear.To investigate the characters of parallax stereo watching asthenopia,the EEG of observers were recorded through the whole watching process of parallax stereo films until watching asthenopia appeared.The recorded EEG data of observers belongs to time-domain information.Fourier transform can process these data to frequency spectrum information.Theαandβwaves average power can be got by Newton-Cotes equation from the information.The ratio ofβpower to the sum ofαandβpower,CV,can be defined as EEG characters value of parallax stereo watching asthenopia and used to estimate the asthenopia degree of observers.Our experiments show that the smaller the CVis,the more serious the asthenopia is.
