Hereinafter, an operation of a mobile navigation apparatus for memo recording local information of a voice according to the present invention will be described with reference to FIGS. 2 to 6.

First, the operation of the voice memo registration mode according to the present invention will be described with reference to FIGS. 2 and 3.

When the navigation device is powered on with the moving of the moving object, the system controller 16 sets the navigation device to the driving mode in step 300 and then performs calculations to determine the current position of the moving object currently driven in step 302. Continue driving while displaying your current location on the screen. When the vehicle arrives at an area where voice memo registration is required, the driver inputs a selection key indicating the voice memo registration mode through the input control unit 14, and the system control unit 16 enters the voice memo registration mode. In step 304 it is checked.

If the voice memo registration mode is confirmed in step 304, the system controller 16 extracts the coordinates of the area for registration in step 306. In this case, the coordinate may be the coordinate of the current point or the coordinate of the passing point. It designates the desired point by using the cursor on the screen, so it extracts the coordinates of the designated area. Depending on the detailed view of the map stored in the map storage unit 18, the area designation may not be clear. In this case, the coordinates of the point closest to the designated place are extracted. When the area coordinates are extracted in this way, the driver uses a microphone installed at an appropriate location in the car to make a voice memo of necessary information about the area. Then, the system controller 16 stores the voice for the local coordinates and the memo extracted in step 308 in the voice storage 22. The system controller 16 stores the voice information of the corresponding region input through the microphone 28 in the voice storage 22 until the voice is no longer memorized in step 310. When the recording of the voice memo for the region is ended, the operation of the current position of the moving object is performed again in step 312 to continue driving while displaying the current position on the map screen, and the system control unit 16 in step 314. After confirming that the vehicle has arrived at the destination, if the destination arrival is confirmed, the operation of the voice memo registration mode ends.

Next, the operation of the voice memo playback mode according to the present invention will be described with reference to FIGS.

When the navigation device is powered on with the moving of the moving object, the system controller 16 sets the navigation device to the driving mode in operation 400. Next, the system control unit 16 calculates the position of the current area being driven in step 402, and searches for the vicinity of the current position. At this time, if the point registered in the voice memo registration mode is confirmed in step 404, the voice memo registered with respect to the point (coordinate) is reproduced through the speaker 26 in steps 406 and 408. In step 402, not only the operation on the current position but also the calculated current position is searched, which is to provide the user with the registered voice memo before passing through the point where the voice memo is already registered.

When the voice memo playback of the corresponding point is ended, it is determined in step 410 whether the voice memo that has just been played back is needed later for efficient use of the voice reproducing unit 24. The reproduced voice memo is deleted from the voice storage unit 22. In addition, in step 410, not only the request for deleting the voice memo but also the change request for the voice memo is checked. When the request for changing the voice memo is confirmed, in step 412, the system controller 16 changes the voice memo. When the reproduction of the voice memo and the deletion / change of the voice memo for the region are ended, the system controller 16 performs operation on the current position of the moving object again in step 414, and the moving object reaches the destination in step 416. After confirming the arrival, if the destination arrival is confirmed, the operation of the voice memo playback mode is terminated.

Next, the operation of the simulation driving mode according to the present invention will be described with reference to FIGS. 2 and 5. This mode simulates driving on the map screen and listens to the voice memo information registered between the starting section and the destination section in advance, and checks the preparations or the contents to be known for the next driving in advance. In addition to driving, even in the first traveled area, the user or a person who is familiar with the area can take notes of the road information and local information at a necessary point, and also can change or delete the memo voice information.

If the simulation driving mode is set by the user after the navigation device is powered on, the system controller 16 sets the navigation device to the simulation driving mode in step 500.

In the simulation driving mode, when the user first looks at the map screen displayed on the display unit 20 and sets the starting point and the destination through the input operation unit 14, the system control unit 16 calculates the optimum path in step 502. The route is searched to display this route on the map screen and displayed on the display unit 20. Thereafter, in step 504, if the point where the voice memo is registered is confirmed in step 506, the voice memo about the point coordinate is reproduced through the speaker 26 in step 508. If it is confirmed in step 510 that the voice memo playback of the corresponding point is ended, the system controller 16 determines whether the voice memo that has just been reproduced later is necessary for efficient use of the voice storage 22 in step 512. If it is judged and unnecessary, the voice storage unit 22 deletes the reproduced voice memo or changes the voice memo if necessary. Then, go back to the driving mode and simulate driving. If the moving object reaches the point where the voice memo is registered, repeat the above process and if the voice memo is needed for the information that the user already knows at any point, Take notes and save the coordinates. In step 518, after confirming that the destination has been reached, the operation of the simulation driving mode is terminated when the destination is reached.

Next, the operation of the voice memo management mode according to the present invention will be described with reference to Figs. This mode shows voice memos managed as the user selects an arbitrary place from the map screen displayed on the display unit 20.

If the voice memo management mode is set by the user after the navigation device is powered on, the system control unit 16 sets the navigation device to the voice memo management mode in step 600, and then, on the display unit 20 in step 602. Display the map screen on. In this case, when the user selects a random place from the map screen displayed on the display unit 20, the system controller 16 confirms that the random place is selected in step 604.

The random place selection from the user identified in step 604 may be a place according to a new registration, or a pre-registered place for changing or deleting a voice memo. In step 606, after confirming whether the random place is selected according to the voice memo new registration, if it is confirmed, the system controller 16 proceeds to steps 612 and 614 and registers the newly registered voice memo. Stores the coordinates corresponding to the voice memo.

On the other hand, if it is determined in step 606 that it is not a random place selection according to the voice memo new registration, the system controller 16 checks whether the voice memo is already registered in step 608 and then the voice memo is already registered. If it is confirmed as a place in step 610 it is determined whether or not to change the voice memo or to delete the voice memo. The operation of changing or deleting the voice memo is performed in step 616. If there is no request to change or delete the voice memo of the registered place, the operation of the voice memo management mode is terminated.

As mentioned above, by taking a note of traffic information or local information using voice, various and flexible help can be obtained according to user's needs, and troublesome operation can be avoided when registering local information, and the time required for registration can be shortened. There is an advantage. In addition, it is possible to register local information without looking at the map screen while driving, thus preventing the risk of an accident, and knowing the local information while driving in advance, there is an advantage of safe and convenient driving.
