1. An eyeglass-type electroencephalogram interface system having an endpiece portion, a rim portion, and a nose pad portion, and to be worn on a head of a user, comprising:

  • an output section, disposed at the rim portion, and configured to present a visual stimulation to the user;

    an ear electrode portion disposed at a position coming in contact with an ear of the user when the eyeglass-type electroencephalogram interface system is worn;

    a facial electrode portion disposed at the nose pad portion coming in contact with a face of the user below a straight line connecting an external canthus and an internal canthus of an eye of the user, such that the mass of the eyeglass-type electroencephalogram interface system is supported at the nose pad portion, when the eyeglass-type electroencephalogram interface system is worn; and

    an electroencephalogram measurement and determination section configured to measure an event-related potential on the basis of a potential difference between the ear electrode portion and the facial electrode portion, based on a timing of presenting the visual stimulation as a starting point.
