Abstract: A method for activating an operational mode change of a device. The method includes flashing at least one indicator, wherein each of the at least one indicator flashes at a particular initial frequency. The method also includes receiving electroencephalograph (EEG) data from an EEG device of a user. The method further includes recognizing a portion of the received EEG data to substantially match activation EEG data, wherein the activation EEG data corresponds to predicted or recorded EEG data of the user in observance of one of the at least one indicator flashing at the particular initial frequency. The method additionally includes activating an operational mode change for providing power to a display upon recognizing the portion of the received EEG data to substantially match the activation EEG data.

Abstract: A device for controlling a pointer includes an electroencephalograph for detecting signals in the midline occipital region of the user's brain, and a display system having a pointer surrounded by flashing regions having differing flashing frequencies. The electroencephalograph detects differing signals caused by the differing flashing frequencies whenever the user is looking at one of the flashing regions having differing flashing frequencies, and the device moves the pointer in the relative direction of that region. All regions remain in the same position relative to the pointer.
