Abstract

PURPOSE:To allow a navigation device to navigate a subject with care in a predetermined area and to better the serviceability of the device by displaying information about the current position relative to a first destination when the current position exists within the predetermined area including the first destination, and displaying information about a second destination when the current position goes out of the predetermined area. CONSTITUTION:A plurality of targets are set by an input portion 9 and then navigation for the first target is carried out and the distance to and direction of the first target are displayed 7. When the current position reaches the target zone a first beep is emitted from a buzzer 5 and the target zone is displayed 7 as having been detected. Even after the current position enters into the target zone the distance to and direction f the target can be displayed by control of the input portion 9. When the current position goes out of the first target zone a second beep is emitted from the buzzer 5 and information about a second destination is displayed.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device suitable for guiding a user to a destination.

0002

[Prior Art] By receiving radio waves from GPS satellites, the current location is measured, the distance and direction to the set destination (target) position are displayed, and the user is guided to the destination. Navigation devices are known.

In this case, if there is one target, the distance from the current location to the target location and the direction of the destination location are displayed on the screen in numbers or the like at regular time intervals.

[0004] When the current location reaches within a predetermined area including the target location, a message to that effect is displayed on the screen and a beep sound is emitted.

On the other hand, when there are multiple targets (for example, when passing through a first destination and a second destination to reach a third and final destination), within a predetermined area including the first destination position (
When the current location enters the target zone (e.g., within a circle with a radius of 300 m centered on the target position), a message indicating that the target zone has been detected will be displayed on the screen, a beep will be emitted, and processing such as positioning will proceed to the next step. Can be switched to target.

[0006]The screen display is maintained until a predetermined operation (for example, a key input operation on the operation unit) is performed, and in response to the predetermined operation, the distance and direction to the next second destination are displayed. You can switch to the screen shown below.

[0007]

[Problem to be solved by the invention]

[0008] Therefore, within the target zone, the distance and direction to the target position are not displayed on the screen.
Not convenient to use.

[0009] Furthermore, target switching (automatic) and
Since screen display switching (predetermined operations) is not supported, the user may be confused.

[0010] An object of the present invention is to provide detailed navigation around a target and excellent usability;
To provide a navigation device that allows a user to easily and reliably recognize target switching.

[0011]

[Means for Solving the Problems] A navigation device according to the present invention provides a method for determining the current location relative to a first destination location on the condition that the current location exists within a predetermined area including a preset first destination location. A first display means 3, 7, 9 on which information about the current location is visually displayed, and the current location relative to a preset second destination location on the condition that the current location reaches from within the predetermined area to outside the predetermined area. second display means 3, 7 on which information about the second display is visibly displayed;
It is characterized by having the following.

0012

[Operation] In the navigation device according to the present invention, when the current location exists within a predetermined area including the first destination, information regarding the current location (e.g., direction, distance) with respect to the first destination is displayed. .

[0013] When the current location moves out of the predetermined area, information regarding the current location relative to the second destination location is displayed.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the navigation device according to the present invention will be described below with reference to the drawings.

In FIG. 1, a receiver 1 receives radio waves from a GPS satellite and inputs them to a control section 3.

The control section 3 is mainly composed of a microcomputer, etc., and controls the activation of the buzzer 5 and the display of various contents on the display 7 in response to the operation of the key input section 9. conduct.

The processing procedure performed by the control unit 3, which is the gist of the present invention, will now be explained with reference to the flowchart shown in FIG.

First, when a plurality of targets are set using the key input unit 9 (the order of each target is set), navigation to the first target is performed, so information regarding the current location with respect to the first target, That is, the distance to the first target and the direction of the first target are each displayed on the display 7 (step S1).

The display continues to be displayed one after another until the current location enters a predetermined area (target zone; for example, within a circle with a radius of 300 m centered on the target location), and when the current location reaches the boundary of the target zone ( Step S3 YES), the buzzer 5 emits a first beep sound, and the display 7 displays that the target zone has been detected (Steps S5 and S7).

In this case, even if the current location is within the target zone, the distance and direction to the target can be displayed by operating the key input section 9 (step S9).
, when exiting the target zone of the first target (step S11 YES), a second beep sound (different sound from the first beep sound) is emitted from the buzzer 5 (step S13).

[0021] In this manner, by making the beep sounds different when entering the target zone and when exiting the target zone, the user can clearly grasp the movement situation.

[0022] Then, on the condition that the next target is set (not the final target) (step S15 YES), processing for navigation to the next target (second destination) is performed (step S15). S17), the process returns to step S1 and similar processing is performed.

As explained above, in this embodiment, since the distance and direction to the first target are displayed even within the target zone, it is easy to use.

Furthermore, when exiting the target zone, the display changes to the next target with a beep sound, so the user can easily and reliably recognize the change.

[0025]

As can be understood from the above explanation, in the navigation device according to the present invention, when the current location exists within a predetermined area including the first destination location, the navigation device according to the present invention provides information regarding the current location relative to the first destination location. Information (e.g. bearing, distance) is displayed.

[0026] When the current location moves out of the predetermined area, information regarding the current location relative to the second destination location is displayed.

[0027] Accordingly, navigation around the first destination (within a predetermined area) can be performed in detail, resulting in excellent usability.

Furthermore, since the timing of switching between the display for the first destination and the display for the second destination is appropriate, the user can easily and reliably recognize the switch.
