Patent attributes
An electroencephalogram interface system includes: sections for measuring an electroencephalogram and an eye movement; an output section for presenting on a screen an option related to a device operation; a highlight determination section for, if a predetermined time has elapsed since a rotational angular velocity of the eye movement becomes equal to or less than a threshold value, identifying a region of the screen in which the user is fixing one's gaze based on the eye movement, and determining an option to be highlighted; an interface section for highlighting the determined option, and determining an operation of the device based on an event-related potential in the signal based on the timing of highlighting the option; and a timing adjustment section for adjusting a timing of beginning highlighting based on the eye movement after a process of displaying the option on the screen is begun and until the option is displayed on the screen.
