Abstract: A terminal device 100 recognizes a swipe operation from a user on a touch panel 120. A control unit 16 reads out information on the resolution from a storage unit 13. Additionally, the control unit 16 sets a threshold value Dth in accordance with a required movement distance Lth by which the swipe operation is determined to be valid. Specifically, the control unit 16 calculates the threshold value Dth by multiplying the required movement distance Lth by the resolution read out from the storage unit 13.

Abstract: It is an object of this invention to provide a navigation apparatus capable of appropriately guiding a user in an intersection and an interchange point. The navigation apparatus is preferably applicable to a navigation apparatus of a movable body such as a vehicle, and includes a display unit and a control unit. The display unit displays map information on a display screen. The control unit allocates a number to passage points in an order from the passage point near a guide point to the passage point far from the guide point, and displays the allocated number in a vicinity of the passage point on the display screen. The guide point indicates a place necessary for a user to turn right or left, and the passage point indicates a place at which turning right or left is possible and which exists between a present position of the user and the guide point. Thereby, the navigation apparatus can appropriately guide the user at the intersection and the branch point.
