A navigation apparatus determines whether a correction-type-vs.-brain-wave-pattern storing unit stores a correction pattern substantially matching a brain wave pattern produced from a detected brain wave signal by comparing the brain wave pattern with a plurality of types of correction patterns pre-stored in the storing unit, and then determines whether or not an issue of a corresponding correction instruction is appropriate based on the detected current position of a moving object and the one displayed on a display unit when determining that a correction pattern substantially matching the recognized pattern exists in the storing unit. The navigation apparatus then makes a correction to a screen display showing the current position of the moving object according to the correction instruction when determining that an issue of the correction instruction is appropriate.
