Here, “ranking” in this example is information indicating the degree of popularity obtained by extracting and classifying genres and keywords from articles such as information magazines using known techniques such as morphological analysis and classifying them by the genres and keywords. Means. The “ranking” may be a ranking by an information provider such as a company, or may be a ranking based on a result of totaling evaluations by a plurality of general users. The same applies to the “introduction article”.

  The comment creation information storage unit F4 is a storage medium that stores comment creation information required when the navigation device 10 creates a comment in the comment creation process. In the comment creation information, it is assumed that a comment creation condition is associated with a basic sentence used when the comment creation condition is satisfied.

  FIG. 4 is an explanatory diagram illustrating an example of a storage state of comment creation information in the comment creation information storage unit F4. As shown in FIG. 4, the comment creation information in this example is information including a comment number (comment No), a basic sentence, a display priority, a blank insertion word, a comment creation condition, and a comment creation flag. is there.

  In the comment creation information, for each comment No., one or more basic sentences, a display priority corresponding to the basic sentence, and a predetermined portion in the basic sentence (a blank part previously provided in the basic sentence. In FIG. , The symbol “□” and “○” part), the blank insertion word that is the character string (or the information on the basis of the inserted character string such as the estimated arrival time), the comment creation condition, and the comment A comment creation flag indicating whether or not to determine whether or not a creation condition is satisfied is associated. In the comment creation process described later, when the comment creation condition with the comment creation flag set to “1” is satisfied, a blank insertion word is determined according to the user's situation and inserted into the basic sentence to comment Is created. When a predetermined comment display condition (a condition indicating that safety can be estimated to be ensured even if the concentration on driving is reduced, such as when the vehicle stops traveling) is satisfied The created comment is displayed according to the display priority. When “0” is set in the comment creation flag, whether the comment creation condition is satisfied is not determined. In addition, the facility name in the comment creation condition may be stored linked to the POI information stored in the POI information storage unit F3.

  The comment creation conditions in this example include POI information such as “when POI information indicating a predetermined condition (for example, including keywords such as“ meal ”and“ family ”) is located within a predetermined range from the current location of the vehicle”. Such as those defined in relation to the function of the navigation device 10 such as “when the estimated arrival time to a predetermined transit point is within a preset time” These conditions can be set. If the navigation system 100 is connected to a camera device, the content that can be read from the camera image may be reflected. Specific examples of information related to comment creation conditions include vehicle travel history (route, speed), destination and destination route, information search history, facilities around current location, time information, sensor information The vehicle state can be considered.

  The basic sentence in this example includes sentences having the same blank insertion word and different styles. That is, as shown in FIG. 4, for example, “present” and “now” in “currently close to □” and “currently close to □”. (Phrases) are included. Also, a basic sentence whose tone (sentence) is different from other basic sentences, such as a so-called colloquial tone such as “I came near □” may be included. Note that if the basic sentence becomes too long, it may be difficult to create the comment that the user intended, and it may take a long time for the user to check the comment content. It is good also as a structure which restrict | limits the number of characters of the possible basic sentence. Further, when the number of characters when a blank insertion word is inserted into the basic sentence (that is, the created comment) exceeds a predetermined number, the comment may not be displayed.

  Further, it is assumed that a blank insertion word has a set condition set according to a comment creation condition. That is, for example, when “when passing the main intersection” is stored as the comment creation condition, for example, “main intersection name” needs to be set as the blank insertion word condition. Thus, when it is determined from the position information and map information that the vehicle has passed the main intersection, the name of the main intersection that has passed is specified by the control unit C and stored as a blank insertion word. Whether or not the character string is stored as a blank insertion word can be determined by referring to the POI information. The blank insertion word condition is set in advance by the provider or the user of the navigation apparatus 10, and the contents once set can be edited. Also, a plurality of blank insertion words can be set in one basic sentence. In this case, the configuration may be such that the position of the blank in the basic sentence and the setting content of the blank insertion word are stored in association with each other.

  The transmission destination information storage unit F5 is a storage medium for storing transmission destination information regarding a transmission destination to which the created comment is transmitted.

FIG. 5 is an explanatory diagram illustrating an example of a storage state of transmission destination information in the transmission destination information storage unit F5. As illustrated in FIG. 5, the transmission destination information includes a transmission destination name and a transmission destination address. Comments can be sent to not only personal email addresses but also WWW (World
An electronic bulletin board or a web log (blog), which is a kind of web page on Wide Web), can be considered. The transmission destination is selected by the control unit C of the navigation device 10 according to the situation, that is, the content of the comment, the current position (administrative world, sightseeing area, etc.), sensor information, and an available communication network. It is good also as a structure.

  In this example, it is assumed that the information stored in the storage unit F, particularly the contents of comment creation information and transmission destination information, can be edited by the user.

  Next, the operation of the navigation device 10 of the present invention will be described with reference to the drawings. Note that a detailed description of processing not particularly related to the present invention may be omitted.

  FIG. 6 is a flowchart illustrating an example of comment creation processing executed by the navigation device 10. In the comment creation process, the navigation system 100 performs a process for executing an operation for creating a comment according to the user's situation.

  The comment creation process in this example is automatically started when the navigation device 10 is activated. Note that the comment creation processing may be configured to start / stop when the user presses a specific button provided on the input device 70, for example.

  In the comment creation process, the control unit C, at a predetermined time interval (for example, every minute or every five minutes), the current position, the peripheral facilities existing around the current position, the predicted arrival time of the destination, and the route Information necessary for determining whether or not a comment creation condition in which “1” is set in the comment creation flag, such as a predicted passage time of the ground, is satisfied (comment creation condition determination information) is confirmed (step S101). .

  After confirming the comment creation condition determination information, the control unit C determines whether or not the comment creation condition is satisfied (step S102). If it is determined that the comment creation condition is not satisfied (N in step S102), the control unit C transitions to step S101. On the other hand, if it is determined that the comment creation condition is satisfied (Y in step S102), the control unit C identifies the basic sentence corresponding to the satisfied comment creation condition and inserts it in the blank provided in the basic sentence. A blank insertion word is determined and stored according to information (including comment creation condition determination information) related to the current situation such as the current position and current time (step S103).

  When the blank insertion word is stored, the control unit C creates a comment indicating the current state of the vehicle by inserting the blank insertion word into the blank of the basic sentence in the comment creation information by the comment creation unit 16 (step S104). .

  When the comment is created, the control unit C stores the created comment in the storage unit F. In this example, the control unit C stores a comment for each comment No. When a comment having the same comment No. is already stored, the newly created comment is overwritten and stored ( Save). When the created comment is stored, the control unit C transitions to step S101. In this example, even when the comment is not overwritten and saved, only the comment indicating the current situation is set as a transmission candidate. Therefore, when a predetermined time has elapsed since the comment was created, the control unit C reads the comment from the storage unit F. Shall be deleted.

  The comment creation process ends when the navigation device 10 is turned off.

  Next, comment transmission processing executed by the navigation device 10 will be described. In the comment transmission process, a process for transmitting the comment stored in the storage unit F by the comment creation process to the outside using the transmission destination information is performed. Note that a detailed description of processing not particularly related to the present invention may be omitted.

  FIG. 7 is a flowchart illustrating an example of the comment transmission process in this example. The comment transmission process in this example is executed when there is a comment that has not been transmitted among the comments created by the comment creation process.

  In the comment transmission process, first, the control unit C determines whether or not the vehicle is stopped based on the vehicle speed information received by the vehicle speed information receiving unit 13 (step S201). If it is determined that the vehicle is in a stopped state (Y in step S201), the control unit C displays a comment selection screen on the display screen 61A of the image display device 61 according to the display priority in the comment creation information ( Step S202).

  FIG. 8 is an explanatory diagram illustrating an example of a comment selection screen. As shown in FIG. 8, the comment selection screen is used to switch the comment display area 101 that displays comments to be selectable and the screen displayed on the display screen 61 </ b> A from the comment selection screen to a normal menu screen, route guidance screen, or the like. A return button 102, a style change button 103 for changing the style of the selected comment, and a decision button 104 for determining the selected comment as a transmission comment.

  The control unit C displays the created comment in the comment display area 101. Note that in this example, the control unit C selects and displays the created comments having the corresponding display priority set to “1” (see FIGS. 4 and 8). That is, in the comment display area 101 in this example, among the created comments, one comment corresponding to each comment No. is displayed.

  When the comment selection screen is displayed, the control unit C accepts selection of the comments 101a and 101b displayed in the comment display area 101 so as to be selectable (step S203). Here, when the selection of the comments 101a and 101b is not accepted (N in Step S203), the control unit C determines whether or not the vehicle has started moving (Step S204). Here, if it determines with the vehicle having started moving (Y of step S204), the control part C will erase | eliminate a comment selection screen, and will change to step S201.

  On the other hand, if it is determined that the selection of the comment has been received in accordance with the operation of the input device 70 by the user (Y in step S203), the control unit C determines whether the selection of the style change button 103 has been received (step S205). . In this example, upon accepting that the user has selected the comments 101a and 101b displayed in the comment display area 101, the control unit C temporarily selects the selected comment as a comment in the “selected state”. To remember. Further, upon accepting selection of a comment in the “selected state”, the control unit C cancels the “selected state”. When there is no comment in the “selected state”, the control unit C does not accept selection of the style change button 103 and the determination button 104. Here, the case where the comment 101a is in the selected state will be described as an example.

  If it is determined that selection of the style change button 103 is not accepted when one or more comments are in a selected state (N in step S205), the control unit C determines whether selection of the decision button 104 has been accepted. (Step S206). If it is determined that the selection of the determination button 104 has not been received (N in step S206), the control unit C determines whether or not a request to cancel the comment selection state (comment selection cancellation request) has been received ( Step S207). If it is determined that a comment selection cancellation request has not been received (N in step S207), the control unit C transitions to step S205.

  On the other hand, if it is determined that a comment selection cancellation request has been received (Y in step S207), the control unit C cancels the comment selection state (step S208), and proceeds to step S203.

  On the other hand, when determining that the selection of the determination button 104 has been received (Y in step S206), the control unit C refers to the transmission destination information storage unit F4 and displays the transmission destination selection screen on the display screen 61A (step S209). .

  FIG. 9 is an explanatory diagram illustrating an example of a transmission destination selection screen. As shown in FIG. 9, the transmission destination selection screen includes a transmission destination display area 201 and a transmission button 202.

  When the transmission destination selection screen is displayed, the control unit C selects the transmission button 202 in a state where one of the transmission destination names 201a and 201b displayed in the transmission destination display area 201 is selected (selected state). Is received, the address corresponding to the transmission destination name in the selected state is determined as the transmission destination, and the comment 101a in the selected state when the determination button 104 is selected (Y in step S206) (or will be described later). The change candidate comment 302a in the selected state on the style change screen to be transmitted (see FIG. 10) is transmitted (step S210), and the process here is terminated.

  On the other hand, when it is determined that the selection of the style change button 103 has been received (Y in step S205), the control unit C displays the style change screen on the display screen 61A (step S211).

  FIG. 10 is an explanatory diagram illustrating an example of a style change screen. As shown in FIG. 10, the style change screen includes a change target comment display area 301, a change candidate comment display area 302, a display switching button (comment selection screen button) 303 for returning to the comment selection screen, and a determination button 104. Including. Here, in the change target comment display area 301, the comment that was in the selected state when the style change button 103 was selected is displayed. In addition, in the change candidate comment display area 302, as in the comments displayed in the change target comment display area 301, comments with different styles including the current situation of the vehicle (that is, change candidate comments having the same comment No and different basic sentences) 302a, 302b) are displayed according to the display priority.

  When the style change screen is displayed, the control unit C accepts selection of a change candidate comment (step S212). If the selection of the change candidate comment is not accepted (N in step S212) and the selection of the display switching button 303 is accepted, the control unit C switches the screen displayed on the display screen 61A from the style change screen to the comment selection screen. Then, the process proceeds to step S205.

  On the other hand, for example, when selection of the change candidate comment 302a is received (Y in step S212), the control unit C cancels the selection state of the comment 101a that was in the selected state on the comment selection screen, and the change candidate comment 302a selects The information is temporarily stored as being in a state, and the corresponding display priority is changed (step S213). That is, for example, the display priority corresponding to the change candidate comment 302a is changed to "" by exchanging the display priority corresponding to the comment 101a in which the selected state is released and the change candidate comment 302a that is newly selected. 1 ”. When the selection of the change candidate comment 302a in the selected state is received, the control unit C cancels the selection state of the change candidate comment 302a, sets the comment 101a to the selected state, and returns the display priority to before the change. Then, the process proceeds to step S212.

  When the display priority is changed, the control unit C determines whether selection of the determination button 104 has been accepted (step S214). If it is determined that the selection button 104 has been selected (Y in step S214), the control unit C transitions to step S209.

  On the other hand, if the selection of the determination button 104 is not accepted (N in step S214) and the selection of the display switching button 303 is accepted, the control unit C deletes the style change screen and transitions to step S202. At this time, the control unit C cancels the selection state of the change candidate comment 302a, but adopts the display priority after the change. Thereby, the content of the comment 101a on the comment selection screen is changed to the content of the change candidate comment 302a.

  In addition, the control part C is good also as a structure which performs movement determination of a vehicle independently of comment transmission processing, and stops comment transmission processing according to detecting the movement of a vehicle. Further, when the movement of the vehicle is detected during the execution of the comment transmission process, the control unit C interrupts the comment transmission process, and then resumes the comment transmission process from the previously interrupted step when detecting the stop of the vehicle. It is good.

  As described above, in the above-described embodiment, the current position of the moving object (for example, a vehicle) is displayed on the map on the display screen of the display device (for example, the display screen 61A of the image display device 61). The navigation device 10 that guides the mobile body to the destination includes a comment creation information storage unit F4 that stores comment creation information in which a comment creation condition is associated with a basic sentence used when the comment creation condition is satisfied. Determine whether the comment creation conditions are met, and when it is determined that the comment creation conditions are met, refer to the comment creation information to identify and move the basic sentence associated with the comment creation conditions Check the current state of the body (for example, comment creation condition judgment information), and check the blank insertion word to be inserted in the blank provided in the specified basic sentence Determined according to the current situation, insert the blank insertion word determined in the blank of the specified basic sentence to create a comment including the current situation of the mobile object, and display the created comment on the display screen 61A, Since the created comment is transmitted in response to a transmission instruction (for example, selection of the decision button 104), an external device is created by creating a sentence according to the user's situation without hindering concentration on driving. Will be able to send to.

  That is, the navigation device 10 can create a sentence by determining a blank insertion word corresponding to the current situation of the user and inserting it into the basic sentence, so the user is willing to create a sentence. You will not be drawn and you can concentrate on driving. In addition, by accepting editing of comment creation information such as basic texts by the user in advance, it becomes possible to create a comment according to the user's intention.

  In the above-described embodiment, the navigation device 10 receives a change instruction of the displayed comment style, and in response to the reception of the change style instruction, a comment (for example, a change target) A style change comment in which the style is changed for the comment displayed in the comment display area 301, and the style change comment including the current status of the moving body (for example, a vehicle) in the same manner as the comment that received the style change instruction , The comment displayed in the change candidate comment display area 302) is displayed on the display screen 61A, so that a comment according to the user's intention can be transmitted.

  Although not particularly mentioned in the above-described embodiment, the navigation device 10 changes the word used in the comment in the comment (for example, the comment displayed in the change target comment display area 301) that has received the style change instruction. At least any of the style change comment (for example, the change candidate comment 302a for the comment 101a) and the style change comment (for example, the change candidate comment 302b for the comment 101a) in which the style of the comment received the style change instruction has been changed It is good also as a structure which displays either. That is, two or more basic sentences are always associated with each comment No, and at least one or more stylistic change comments are displayed according to the stylistic change instruction, so that a comment according to the user's intention may not be displayed. Can be reduced.

  Although not particularly mentioned in the above-described embodiment, the navigation device 10 predicts the current position of the moving object (for example, a vehicle), the surrounding facilities existing around the current position, and the arrival prediction of the destination. It is good also as a structure which confirms any one or more among time and the passage estimated time of a waypoint. By including these in the current status to be confirmed, the comment to be created can be made a comment indicating the current status of the user.

  Although not particularly mentioned in the above-described embodiment, the navigation device 10 specifies a basic sentence every time it is determined that a comment creation condition is satisfied, and creates a comment every time a basic sentence is specified. The plurality of created comments may be displayed so as to be selectable. By not limiting the number of comment creations, it is possible to increase the possibility of creating a comment that the user does not predict, and to increase the preference for comment selection.

  In the above-described embodiment, the navigation device 10 is configured to display a newly created comment when a comment is newly created for the same basic sentence, and thus is close to the current situation of the user. A comment to be transmitted can be selected from comments.

  In the above-described embodiment, the case where the user selects the comment transmission destination has been described. However, the comment creation information and the transmission destination information are stored in association with each other so that the user can select the transmission destination. The step of accepting may be configured to be omissible. With such a configuration, the time required for the user to send a comment can be shortened. This is particularly effective when the comment destination is always limited to a specific partner, such as when the user is only interested in writing on an electronic bulletin board on the Internet.

  Although not particularly mentioned in the above-described embodiment, the control unit C accumulates the comment created in the comment creation process and the comment transmission history in the storage unit F, and the once sent comment is displayed again. It is good also as a structure which does not. With such a configuration, a user who has finished driving a vehicle can check comments created during driving by referring to the comment creation information. That is, for example, after the driving is finished, the created comment can be provided as a reference when the user confidence creates a comment. Also, the display priority in the comment creation information can be calculated from the transmission history.

  Also, the time when the comment was created and the time when the comment was sent are stored, and the comment selection screen display condition (or display priority calculation) indicates that there is a comment created after the last sent comment. In the comment display area 101, only a comment created after the last transmitted comment may be displayed. With such a configuration, it becomes possible to display and transmit a more real-time comment.

  Further, the display method of the style change screen is not limited to the above-described embodiment (see FIG. 10). For example, in response to selection of the comment 101a displayed in the comment display area 101 on the comment selection screen, The change candidate comment to be displayed may be displayed in a pull-down manner.

  INDUSTRIAL APPLICABILITY The present invention is industrially useful in an industry that handles devices that provide vehicle route guidance, and is also useful in the market for electrical appliances such as car navigation devices capable of information communication.
