PORTABLE NAVIGATION DEVICE AND METHOD WITH ACTIVE ELEMENTS
First Claim
1. A portable navigation device comprising:
- a housing;
a position detecting section that detects a current position;
an input section that receives an input for specifying a destination;
a destination direction detecting section that detects a destination direction to the destination from the current position;
a terminal direction detecting section that detects a terminal direction of the housing;
at least three active elements disposed at different positions on or in the housing;
an angular difference calculating section that calculates an angular difference between the destination direction and the terminal direction; and
an active element control section that determines respective tactile sensation intensities of the at least three active elements based on the angular difference to control the at least three active elements in accordance with the tactile sensation intensities.

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 θ 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.
