Hands-free electroencephalography display enablement and unlock method and apparatus

A method for unlocking a device, comprising:

• displaying a plurality of flashing regions, each region of the plurality of flashing regions flashing at a different frequency, wherein each region of the plurality of flashing regions overlaps with at least another region of the plurality of flashing regions such that a particular location on a display is locatable based upon one or more relative flashing frequencies or intensities at or in proximity to the particular location on the display at a particular time;
• receiving electroencephalograph (EEG) data of a user;
• recognizing at least two sequential portions of the received EEG data to substantially match at least two location EEG data sets, each of the at least two location EEG data sets associated with one particular location of at least two particular locations on the display at one time of at least two particular times;
• determining a track of the user's point of focus as the user's point of focus moves across the display based upon recognizing the at least two sequential portions of the received EEG data to substantially match the at least two location EEG data sets;
• and
• unlocking the device if the track of the user's point of focus substantially matches a predetermined track of the user's point of focus.
