  ADVANTAGE OF THE INVENTION According to this invention, in the navigation apparatus which memorize | stores the memo input by handwriting in relation with the specific point on a map, the point which associates a memo can be changed freely.

  A configuration of a navigation apparatus according to an embodiment of the present invention is shown in FIG. This navigation device is used by being mounted on a vehicle, and records characters, symbols, figures, and the like input by handwriting on a touch panel as memo information. The navigation device 1 shown in FIG. 1 includes a control circuit 11, a ROM 12, a RAM 13, a current location detection device 14, an image memory 15, a display monitor 16, an input device 17, and a disk drive 18. The disc drive 18 is loaded with a DVD-ROM 19 in which map data is recorded.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various processes and controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. Based on the map data recorded on the DVD-ROM 19, the control circuit 11 displays a road map, sets a destination, searches for a recommended route to the set destination, and the like.

  The current location detection device 14 is a device that detects the current location of the host vehicle. For example, a vibration gyro 14a that detects the traveling direction of the host vehicle, a vehicle speed sensor 14b that detects a vehicle speed, and a GPS sensor that detects a GPS signal from a GPS satellite. 14c and the like. The navigation device 1 can determine a route search start point when searching for a recommended route based on the current location of the host vehicle detected by the current location detection device 14.

  The image memory 15 temporarily stores image data to be displayed on the display monitor 16. The image data includes road map drawing data for displaying a road map, various graphic data, and the like, and is created by the control circuit 11 based on the map data recorded on the DVD-ROM 19. Various images such as road map images are displayed on the display monitor 16 using the image data stored in the image memory 15.

  A touch panel 16a is combined with the display monitor 16, and when any position on the display monitor 16 is touched by a user's finger or the like, information indicating the touch position is output from the touch panel 16a to the control circuit 11. . Based on the touch position information, the control circuit 11 determines which part of the image displayed on the display monitor 16 is touched at that time. The navigation device 1 according to the present embodiment performs various processes according to touch panel operations from the user detected by the touch panel 16a and the control circuit 11.

  The input device 17 is for accepting various operation inputs from the user, and is realized by an operation panel, a remote controller, or the like. For example, the input device 17 performs operations such as inputting a search condition for searching for a destination facility, instructing a map scroll direction, and changing a map scale. These operations can also be performed by the touch panel operation described above. Therefore, the input device 17 is not essential in the navigation device 1 of the present embodiment, and may not be provided.

  The disk drive 18 reads map data for displaying a road map from the loaded DVD-ROM 19. This map data represents route calculation data used for route search to the destination, route guidance data used to guide the vehicle to the destination according to the recommended route, such as intersection name and road name, and roads Includes road data. The map data also includes background data representing map shapes other than roads such as rivers, railways, various facilities on the map (landmarks), and the like.

  In the road data, the minimum unit representing a road section is called a link, and each road is composed of a plurality of links. A point connecting the links is called a node, and each node has position information (coordinate information). The link shape, that is, the shape of the road is determined based on the position information of the node. Although an example using a DVD-ROM is described here, the map data may be read from a recording medium other than the DVD-ROM, such as a CD-ROM or a hard disk.

  When the destination is set by the user by the operation of the input device 17 or the touch panel operation, the navigation device 1 uses the current location detected by the current location detection device 14 as a route search start point, based on the above-described route calculation data. A route search from the current location to the destination is performed by calculating the algorithm. The recommended route obtained as a result of the route search is displayed on the road map separately from other roads by changing its display form, for example, display color. Thus, the user can recognize the recommended route on the road map displayed on the display monitor 16. In addition, the navigation device 1 guides the host vehicle by instructing the traveling direction by an image or voice to the user so that the host vehicle can travel according to the recommended route. In this way, route guidance to the destination is performed by displaying the road map and guiding the vehicle to the destination according to the recommended route.

  An example of a road map image displayed on the display monitor 16 in the navigation device 1 of the present embodiment is shown in FIG. In this road map image, a vehicle position mark indicating the vehicle position is displayed at the center of the map, and a recommended route is displayed with a thicker line than other roads. A memo input button indicated by reference numeral 21 is displayed at the right end of the screen. When the memo input button 21 is pressed by the user, a handwritten memo input screen is displayed, and the navigation device 1 shifts to a mode for accepting an input of the handwritten memo from the user.

  FIG. 3 is an example of a handwritten memo input screen displayed when the memo input button 21 of FIG. 2 is pressed. In this handwritten memo input screen, when the user traces the input field indicated by reference numeral 22 on the display monitor 16 with a finger or the like, the locus of the touch position is acquired by the navigation device 1 as a handwritten memo, and the contents of the handwritten memo are further displayed. It is stored in the navigation device 1. Thereby, the user can input memo information including arbitrary characters, symbols, figures, and the like by handwriting and store the memo information in the navigation device 1 as a handwritten memo. For example, as shown in FIG. 3, the characters “Tomei Work 8/4 to 8/6, near Gotemba” inputted by handwriting are stored as handwritten memos.

  Portions indicated by reference numerals 23, 24, 25 and 26 are tabs for switching between the handwritten memo input screen of FIG. 3 and the various display setting screens shown in FIGS. Among these, the tab 23 written as “input” is used for switching from another screen to the handwritten memo input screen of FIG. 3. That is, when the tab 23 is pressed while any one of the screens shown in FIGS. 4, 5 and 6 described below is displayed on the display monitor 16, the handwritten memo input screen shown in FIG. 3 is displayed.

  The tab 24 written as “period” is used for switching to the display period setting screen shown in FIG. When the tab 24 is pressed, a screen as shown in FIG. 4 is displayed on the display monitor 16. The user can set a period for displaying the handwritten memo on the display period setting screen. For example, as shown in FIG. 4, when a mark written as “one month from today” is selected by the user's touch panel operation, the display condition described later is satisfied for one month from the input date of the handwritten memo. Sometimes the contents of the handwritten memo are automatically displayed. Note that when a part written as “detailed setting” is selected, a screen for setting a more detailed display period by specifying a date or the like is displayed.

  The tab 25 written as “trigger” is used for switching to the display trigger setting screen shown in FIG. When the tab 25 is pressed, a screen as shown in FIG. 5 is displayed on the display monitor 16. The user can set conditions for displaying a handwritten memo on the display trigger setting screen. For example, as shown in FIG. 5, when a mark written as “From the present location” and a mark written as “500 m” are selected by the user's touch panel operation, the mark is automatically within 500 m from the point where the handwritten memo is pasted. When the vehicle position approaches, the contents of the handwritten memo are automatically displayed. In addition, when the mark written “From recommended route” is selected instead of the mark “From current location”, when the recommended route approaches within 500 m from the point where the handwritten memo is pasted, The contents of the handwritten memo are automatically displayed. A method for pasting a handwritten memo on the map will be described later.

  The tab 26 written “Sound” is used for switching to the display sound setting screen shown in FIG. When the tab 26 is pressed, a screen as shown in FIG. 6 is displayed on the display monitor 16. The user can set the presence or absence of a sound when displaying a handwritten memo on the display sound setting screen. For example, as shown in FIG. 6, when a mark written “ON” is selected by a user's touch panel operation, a predetermined sound is output when the contents of a handwritten memo are automatically displayed as described above. The On the other hand, when a mark written as “OFF” is selected, such audio output is not performed.

  When the end button 27 is pressed on any of the screens of FIGS. 3 to 6, the input of the handwritten memo ends. At this time, the contents of the handwritten memo input in FIG. 3 and the contents of the various setting conditions set in FIGS. 4 to 6 are temporarily stored by the navigation device 1.

  When the input of the handwritten memo is completed as described above, the memo pasting screen shown in FIG. On the memo pasting screen, a memo icon 30 representing the input handwritten memo is displayed together with the map image. When the user touches the memo icon 30 with a finger or the like and moves (drags) on the display monitor 16 while touching the memo icon 30, a copy of the memo icon 30 is created and is created in accordance with the movement of the finger or the like. A copy of the memo icon 30 moves on the map image. Thereby, the input handwritten memo can be pasted at an arbitrary point on the map.

  FIG. 8 and FIG. 9 show how a handwritten memo is pasted by creating and moving a copy of the memo icon 30 as described above. When the memo icon 30 is dragged by the user's touch panel operation, a memo icon 31 that is a copy of the memo icon 30 is created as shown in FIG. 8, and the memo icon 31 moves on the map image. When the user drags the memo icon 31 to a point where the input handwritten memo is to be pasted, the user releases the finger that performed the drag operation from the display monitor 16. Then, the memo icon 31 is displayed at the position where the finger is released, and the handwritten memo is pasted at the point corresponding to the position on the map image. When the vehicle position or recommended route approaches within the distance set by the display trigger setting screen of FIG. 5 from the memo pasting point, the contents of the pasted handwritten memo, that is, the handwritten characters shown in FIG. Is displayed.

  When pasting a handwritten memo at another point, another memo icon 32 is created as a copy of the memo icon 30 as shown in FIG. 9 by dragging the memo icon 30 as in FIG. Is pasted at the point where the user releases the finger. By repeating the same operation as this, the user can paste an arbitrary number of handwritten memos at arbitrary points. As described above, in the navigation device 1 of the present embodiment, a plurality of memo icons are created by duplicating the memo icon representing the handwritten memo input by the user, and the plurality of memo icons are moved to different positions on the map image. Thus, the input handwritten memo can be pasted to a plurality of points.

  Note that a position confirmation button 41, a location search button 42, and a genre designation button 43 are displayed on the screens shown in FIGS. When the position confirmation button 41 is pressed by the user's touch panel operation, the memo pasting point determined so far is confirmed as described above, and a road map image after pasting the handwritten memo as shown in FIG. 10 is displayed. Transition to the mode to perform. On the road map displayed at this time, memo icons 31 and 32 pasted as described in FIGS. 8 and 9 are displayed.

  The place search button 42 is a button for searching a place where a handwritten memo is pasted. When the location search button 42 is pressed by a user's touch panel operation, a screen for inputting search conditions is displayed. When a search condition such as an address, place name, or facility name is input on the input screen, the corresponding place is searched and a map in the vicinity is displayed. The user can paste a handwritten memo at any point on the map displayed in this way using the method described above.

  The genre designation button 43 is a button for pasting a handwritten memo to a facility of a designated genre. When this genre designation button 43 is pressed by a user's touch panel operation, a screen for designating a facility genre is displayed. By designating any facility genre on the genre designation screen, the corresponding facility is searched, and a handwritten memo is pasted to each facility. At this time, the drag operation for moving the memo icon as described above is unnecessary. In addition, you may make it narrow down further the facilities made into the object which pastes a handwritten memo among the searched facilities. For example, facilities within a predetermined distance from the vehicle position, facilities selected by the user, and the like can be narrowed down as handwritten memo pasting targets.

  As described above, the handwritten memo is input by the user's touch panel operation and pasted at an arbitrary point on the map. FIG. 11 shows a flowchart of processing executed in the control circuit 11 at this time. In step S10, it is determined whether or not the memo input button 21 in FIG. 2 has been pressed. If it has been pressed, the process proceeds to the next step S20.

  In step S20, the handwritten memo input screen of FIG. On this handwritten memo input screen, memo information represented by characters, symbols, figures, etc. is input by handwriting from the user by a touch panel operation. In the next step S30, it is determined whether any of the tabs 23 to 26 is pressed. If any tab is pressed, the process proceeds to step S40, and the display screen is switched according to the pressed tab in step S40. Thereby, any one of the handwritten memo input screen of FIG. 3, the display period setting screen of FIG. 4, the display trigger setting screen of FIG. 5, or the display sound setting screen of FIG. 6 is displayed. In the display setting screens of FIGS. 4 to 6, as described above, the display period of handwritten memos, display conditions, and presence / absence of display sound are set. If step S40 is performed and a display screen is switched, it will progress to the following step S50. On the other hand, if no tab is pressed in step S30, the process proceeds to step S50 without executing step S40.

  In step S50, it is determined whether or not the end button 27 is pressed on any of the screens of FIGS. 3 to 6 displayed on the display monitor 16 at that time. If the end button 27 is pressed, the process proceeds to the next step S60. If the end button 27 has not been pressed, the process returns to step S30, and the handwritten memo input process as described above is continued.

  In step S60, the memo information input by handwriting on the handwritten memo input screen of FIG. 3 is acquired as a handwritten memo and temporarily stored. In the next step S70, the memo pasting screen of FIG. On the memo pasting screen, a memo icon 30 is displayed together with the map image.

  In step S80, it is determined whether or not the user has performed a drag operation on the memo icon displayed in step S70. When the drag operation is performed in the touch panel operation from the user, as described with reference to FIGS. 8 and 9, the memo icon 30 is duplicated in step S90 according to the drag operation, and is duplicated in the next step S91. Move the memo icon on the map image. The point corresponding to the position on the map image where the memo icon has been moved in this way is set as the memo pasting point. If step S91 is performed, it will progress to step S100. On the other hand, if the drag operation is not performed in step S80, the process proceeds to step S100 without executing steps S90 and S91.

  In step S100, it is determined whether the display range of the map has been changed. The map display range is changed by scrolling the map or changing the map scale. When the map display range is changed by these, the process proceeds to step S110, the map of the display range after the change is displayed in step S110, and then the process proceeds to step S120. On the other hand, if the map display range is not changed in step S100, the process proceeds to step S120 without executing step S110.

  In step S120, it is determined whether or not the location search button 42 in FIGS. If the location search button is pressed, the process proceeds to step S130, and the memo attachment location search process shown in the flowchart of FIG. 12 is executed in step S130. The contents of the flowchart of FIG. 12 will be described later. If step S130 is performed, it will progress to the following step S140. On the other hand, if the location search button is not pressed in step S120, the process proceeds to step S140 without executing step S130.

  In step S140, it is determined whether or not the genre designation button 43 in FIGS. If the genre designation button is pressed, the process proceeds to step S150, and the memo pasting genre designation process shown in the flowchart of FIG. The contents of the flowchart of FIG. 13 will be described later. After step S150 is executed, the process proceeds to the next step S160. On the other hand, if the genre designation button is not pressed in step S140, the process proceeds to step S160 without executing step S150.

  In step S160, it is determined whether or not the position confirmation button 41 in FIGS. If the position confirmation button is pressed, the process proceeds to step S170, and in step S170, the memo pasting point determined as described above is associated with the handwritten memo. In the next step S180, the result of step S170 is used to store the memo pasting point and the handwritten memo in association with each other. At this time, the setting conditions such as the display period, display conditions, and presence / absence of display sound set on each display setting screen of FIGS. In step S180, in order to store the memo pasting point and the handwritten memo in association with each other, data representing their contents is recorded in the rewritable ROM 12, for example.

  If step S180 is performed, the flowchart of FIG. 11 will be complete | finished. Thereafter, the map screen after pasting the handwritten memo as shown in FIG. 10 is displayed on the display monitor 16. On the other hand, if the position confirmation button is not pressed in step S160, the process returns to step S80 and the process described in each of the above steps is repeated to continue the handwritten memo pasting process.

  Next, the memo sticking location search process shown in FIG. 12 will be described. In step S131, search conditions are set. When an address, place name, facility name, or the like is input as a search condition in step S131, a place corresponding to the search condition is searched in the next step S132. In the next step S133, a map image near the location searched in step S132 is displayed on the display monitor 16. By executing the processing of steps S90 and S91 in FIG. 11 on this map image, the memo icon is moved to an arbitrary position on the map image in accordance with the user's drag operation. As a result, the point corresponding to the position on the map image to which the memo icon has been moved is set as the memo pasting point. If step S133 is performed, the flowchart of FIG. 12 will be complete | finished and it will return to FIG. 11, and will progress to step S140 following step S130.

  Next, the memo pasting genre designation process shown in FIG. 13 will be described. In step S151, the facility genre is designated. When a facility genre is specified in step S151, a facility corresponding to the facility genre is searched in the next step S152. For example, when the facility genre of “CD, record store” is specified in step S151, the facility corresponding to the CD store or record store is searched in step S152. At this time, only facilities that satisfy a specific condition, for example, facilities that are within a predetermined distance from the position of the vehicle, may be searched.

  In step S153, the facility searched in step S152 is used as a memo pasting point, and a copy of the memo icon displayed in step S70 of FIG. 11 is pasted on the facility. When a plurality of facilities are searched, a copy of the memo icon is pasted using each facility as a memo pasting point. Note that a memo icon may be pasted only for the facility selected by the user among the searched facilities. When step S153 is executed, the flowchart of FIG. 13 is ended, the process returns to FIG. 11, and the process proceeds to step S160 subsequent to step S150.

  As described above, the handwritten memo inputted by the touch panel operation is stored in the navigation device 1, the stored handwritten memo is pasted at an arbitrary point on the map, and the memo pasting point and the handwritten memo are Associate.

  Next, FIG. 14 shows a flowchart of processing executed by the control circuit 11 when the handwritten memo stored in the flowchart of FIG. 11 is automatically displayed on the navigation device 1. In step S200, one of the memo pasting points set in the flowchart of FIG. 11 is selected. Note that one of handwritten memos input by the user is associated with the memo pasting point selected here.

  In step S210, it is determined whether or not the current situation satisfies the display condition set for the memo pasting point selected in step S200. This display condition is set on the display trigger setting screen in FIG. 5 among the display screens after being switched in step S40 in the flowchart in FIG. It is set as a display condition that the memo pasting point is within a predetermined distance from the current location, or that the memo pasting point is within a predetermined distance from the recommended route. If the display condition is satisfied, the process proceeds to step S220. If the display condition is not satisfied, the flowchart of FIG. As described above, in step S210, it is determined whether or not to display the handwritten memo based on the positional relationship between the vehicle position or the recommended route and the memo pasting point.

  In step S220, it is determined whether or not the present is within the set display period. This display condition is set on the display period setting screen of FIG. 4 among the display screens after being switched in step S40 of the flowchart of FIG. If it is within the display period, the process proceeds to step S230. If it is not within the display period, the flowchart of FIG. By executing this step S220, only the handwritten memo that includes the present within the set display period is displayed among the handwritten memos that are determined to be displayed because the display condition is satisfied in step S210.

  In step S230, it is determined whether or not the display sound is set. The presence / absence of the display sound is set on the display sound setting screen of FIG. 6 among the display screens after switching in step S40 of the flowchart of FIG. If the display sound is set, the process proceeds to step S240, and after a predetermined display sound is output in step S240, the process proceeds to step S250. On the other hand, if no display sound is set, the process proceeds to step S250 without executing step S240.

  In step S250, the handwritten memo stored in association with the memo pasting point selected in step S200 is displayed on the display monitor 16. However, it is not displayed when the handwritten memo is already displayed. When a plurality of handwritten memos are displayed, the plurality of handwritten memos may be reduced and displayed side by side, or the user may select which handwritten memos are displayed.

  In step S260, it is determined whether all memo pasting points have been selected in step S200. If there is a memo pasting point that has not been selected yet, the process returns to step S200, and after selecting any of the unselected memo pasting points in step S200, the above processing steps are repeated. If all the memo pasting points have been selected, the flowchart of FIG. 14 ends. As described above, the stored handwritten memo is displayed.

According to the embodiment described above, the following operational effects can be obtained.
(1) Based on the locus of the touch position in the touch panel operation from the user, the memo information input by handwriting from the user is acquired as a handwritten memo (step S60), and the memo icon representing the handwritten memo is displayed together with the map image on the display monitor 16. (Step S70). The memo icon is moved on the map image in accordance with the drag operation in the touch panel operation from the user (step S91), and the point corresponding to the moved position on the map image is set as the memo pasting point, and the memo pasting is performed. The point and the handwritten memo are associated and stored (steps S170 and S180). Since it did in this way, even after inputting a handwritten memo, the point which registers the handwritten memo can be changed freely.

(2) The memo icon is duplicated to create a plurality of icons (step S90), and the plurality of icons are moved to different positions on the map image in step S91. Since it did in this way, the input handwritten memo can be pasted and registered in a plurality of points.

(3) Based on the positional relationship between the vehicle position or the recommended route and the memo pasting point, it is determined whether or not to display the handwritten memo (step S210), and the handwritten memo determined to be displayed is displayed on the display monitor 16. Displayed (step S250). Since it did in this way, what is necessary in the handwritten memo registered in various points can be displayed automatically.

(4) In step S40, the display screen is switched to the display period setting screen of FIG. 4, and the display period of the handwritten memo is set on the display period setting screen. And among the handwritten memos determined to be displayed in step S210, only the handwritten memos that include the present in the set display period are displayed on the display monitor 16 (steps S220 and S250). Since it did in this way, only the handwritten memo within the set display period can be displayed automatically, and the handwritten memo outside the unnecessary display period can be prevented from being displayed.

  In the above-described embodiment, an example in which characters, symbols, figures, and the like input by handwriting from the user are directly acquired as handwritten memos has been described. However, processing such as character recognition is performed on the characters and the like input by handwriting. Thus, the memo information may be acquired as text data. In the present invention, the memo information may be acquired by any method as long as the memo information input by handwriting from the user is acquired based on the locus of the touch position of the user in the touch panel operation. In addition, when the memo information is acquired by the method as described above, by further allowing the user to input the display conditions and display period of the handwritten memo, the presence or absence of display sound with characters, etc., and recognizing the input characters, These contents can also be set.

  Moreover, in said embodiment, the memo information input by handwriting from the user is acquired as a handwritten memo, the handwritten memo is converted into an icon, and the pasted point and the memo information are associated with each other. Although an example has been described, the present invention can be applied to other than handwritten memos. For example, information such as a mail or a photographic image transmitted from a mobile phone may be acquired by a navigation device, and the information may be iconized and pasted at an arbitrary point. Further, when a mobile phone equipped with a GPS (Global Positioning System) receiver is used, the position information detected by the GPS signal received by the mobile phone is transmitted to the navigation device together with the above-mentioned mail and photographic images. Thus, the point indicated by the position information may be automatically associated with information such as an email or a photo image.
