Patent ID: 8466875

Claim:
An electroencephalogram interface system for controlling an operation of a device by utilizing an electroencephalogram signal of a user, comprising: an electroencephalogram measurement section for measuring an electroencephalogram signal of the user; an eye movement measurement section for measuring an eye movement of the user; an output section for presenting on a screen an interface screen containing an option which is related to an operation of a device; a highlight determination section for determining whether a predetermined time has elapsed or not since a point in time when a rotational angular velocity of the eye movement becomes equal to or less than a prestored threshold value, and if the predetermined time has elapsed, identifying a region of the interface screen in which the user is fixing his or her gaze based on the eye movement, and determining an option to be highlighted; an interface section for highlighting the option determined by the highlight determination section, distinguishing a component of an event-related potential contained in the electroencephalogram signal based on the timing of highlighting the option as a starting point, and determining an operation of the device based on the distinguished component; and a timing adjustment section for adjusting a time period before beginning highlighting of the option, based on the eye movement relative to a position of the option after a process of displaying the interface screen is begun and until the interface screen.
