  • Patent number: 8174499
    Abstract: A navigation apparatus is disclosed. The navigation apparatus includes a remote control device having a manipulation member and a force generator. The manipulation member is movable in response to user's manipulation and enables the user to point to a position on a display screen of the display device remotely. The force generator applies a force to the manipulation member against the manipulation of the manipulation member. The navigation apparatus sets content of the force based on an arrangement of an item image on the display screen, so that the force causes the pointed position to be attracted toward a fixed item image when the pointed position is located around the fixed item image, while the first force does not cause the pointed position to be attracted toward an on-map item image, which is superimposed on a map image.
