Title: Portable navigation device and method with active elements

Abstract: A portable navigation device and method are capable of presenting a destination direction to a user without resorting to visual sensation with a relatively simple configuration. Vibration elements are disposed on or in different positions of a housing. The respective vibration intensities of the vibration elements are determined on the basis of an angular difference .theta. between a destination direction Vn and a terminal direction Vd. The vibration elements are respectively controlled in accordance with the determined vibration intensities. The position of a vibration, which is obtained as a result of blending vibrations of the vibration elements is sensed by a user.
