  By the way, it is assumed that a passenger of a vehicle equipped with a navigation device searches the POI data of the navigation device to specify a destination, and performs a purpose such as entertainment and eating and drinking. Even if the passenger wishes to go to the destination again, the same search as the previous time will be executed from the beginning if he / she does not remember the detailed address of the visit destination. Also, if you ’re disappointed with the entertainment and food you ’ve been visiting and you feel you ’re drowned in visiting the same facility, and you do n’t remember the destination, Visiting without knowing that the facility you have visited makes you feel uncomfortable.

  In order to avoid such a situation, it is possible to acquire the information on the visited place by storing the content associated with the position information using the technique described in Patent Document 1. However, even if such technology is used, complicated processing such as application activation and manual input is required to register content, and the target information may be missed while spending time for the search. .

  In view of such problems, an object of the present invention is to provide a navigation device, a navigation method, and a navigation program capable of recording a visited place with a simple operation and improving the convenience of a passenger.

  In order to solve the above-described problems, a typical configuration of the navigation device (100) of the present invention includes a map storage unit (232) that stores map data in advance in a navigation device mounted on a vehicle, A position acquisition unit (202) that acquires position information, a display unit (204), a map based on map data, a display control unit that displays on the display unit the position of the vehicle based on the acquired position information, and a vehicle If the stop determination unit (250) determines that the vehicle is in a stopped state when the elapsed time since the vehicle has stopped at an arbitrary position is equal to or longer than a predetermined time, the vehicle stops when the stop determination unit determines that the vehicle is in a stopped state. Based on the position information of the position, the visit destination candidate derivation unit for deriving one or a plurality of visit destination candidates of the passenger from area data indicating information on the visit destination candidates existing within a predetermined range from the current position ( 52), a visit destination specifying unit (254) for specifying a visit destination visited by the passenger from one or a plurality of visit destination candidates in accordance with the passenger's input, and an area of the visit destination specified by the visit destination specifying unit A storage control unit that stores visit information indicating visit in association with the data in the visit information storage unit (236).

  With this configuration, the passenger can leave the visit information indicating that the visit has been made without any troublesome operations. Then, when searching for destinations with the same purpose on the map data, it is possible to quickly find the target facilities by referring to the visit information, and on the contrary, avoid the facilities that were disappointing. Can also be determined. Furthermore, it is possible to memorize only a more significant visited place by eliminating a short time stop that does not need to be recorded, such as waiting for a signal or just stopping at a vending machine.

  The display control unit further includes a touch panel (210) for displaying one or more visit destination candidates on the display unit and detecting contact with a position corresponding to the one or more visit destination candidates displayed on the display unit, The visited site specifying unit may specify the visited site by contact input of the passenger through the touch panel.

  With this configuration, the passenger can store the visit information indicating that he / she has visited by simply touching the item of the visit destination among the visit destination candidates displayed on the display unit, and easily The operation can be completed in a short time and the operation can be resumed.

  A touch panel for detecting contact with the characters displayed on the display unit is further provided, and the storage control unit further includes the date and time information when the visit is made and the passenger's message input through the touch panel as visit information. When the visit information is associated with the area data corresponding to the facility displayed on the map selected by the passenger, the display control unit stores the visit information as the visit information associated with the area data. Either or both of the date information and the message being displayed may be displayed on the display unit.

  In the present invention, date / time information at the time of a visit and a message input through a touch panel are recorded as the visit information. Furthermore, the recorded date information and message are displayed according to the passenger's selection. With this configuration, the passenger can leave not only the fact of the visit but also the date / time information at the time of the visit and an arbitrary message, and can accumulate more information about the visited place. For example, if it is a restaurant, it is possible to record the quality of the taste and refer to it later when eating out.

  For example, a facility that has passed by the time of stopping is less likely to be a passenger's visit than a facility that has not passed. In addition, there is a high possibility that the facility ahead in the approach direction is a visited site. In the present invention, priority is set for the destination candidate from the approach direction and the direction of the vehicle, and it is confirmed whether the visit is made from the destination candidate of the facility having a high priority, that is, the passenger is likely to visit. To do. With such a configuration, it is possible to specify a visited place with fewer questions and responses, and the passenger can store the visit information with less burden.

  The visited site specifying unit selects a question corresponding to the visited genre information from a plurality of questions associated with the genre information (240) included in the area data, and the voice control unit outputs the selected question as a voice You may make it output to a part.

  With this configuration, for example, when a restaurant is listed as a candidate for a visit, the voice control unit causes the voice output unit to output a question asking about the impression of the meal, so that the passenger responds to the impression of the meal, It can be specified that the visited place was a restaurant. Further, if the visit destination candidate is a bowling alley, the visit destination can be identified more reliably by making a question according to the genre information of the visit destination candidate such as outputting a question about the score.

  The navigation device further includes a voice input unit that inputs the voice of the passenger and a voice output unit that outputs the voice, and the storage control unit is further input with the date and time information at the time of the visit and the voice. When the passenger's message is stored in the visit information storage unit as visit information and the visit information is associated with the area data corresponding to the facility on the map selected by the rider, the visit information associated with the area data is You may further provide the audio | voice control part which outputs either one or both of the stored date information or a message to an audio | voice output part.

  In the present invention, date information at the time of the visit and a message input by voice are also recorded as the visit information. Furthermore, the recorded date information and message can be displayed according to the passenger's selection. With such a configuration, the passenger can leave not only the fact of the visit but also the date / time information at the time of the visit and an arbitrary message, and can accumulate more information about the visited place. For example, in the case of an accommodation facility, it is possible to store impressions regarding bedding and the like and refer to it when selecting an accommodation facility at a later date.

  A visit destination search unit (256) for searching the keyword input by the passenger from the date information or the message is further provided, and the display control unit displays the date information or the destination area data associated with the message that matches the keyword. May be displayed.

  In the following embodiment, it is an object to record the visited place with a simple operation and improve the convenience of the passenger while avoiding the above-described situation. Hereinafter, a configuration of a navigation device according to the embodiment, a navigation method using the navigation device, and a navigation program will be described.

(Navigation device 100)
FIG. 1 is an external view showing an example of the navigation device 100, and FIG. 2 is a block diagram showing the configuration of the navigation device 100. The navigation device 100 includes a storage unit 200, a position acquisition unit 202, a display unit 204, a voice output unit 206, a central control unit 208 that functions as a display control unit, a storage control unit, and a voice control unit, and a touch panel 210. A voice input unit 212, an external storage unit 214, a wireless communication unit 216, a portable position acquisition unit 218, and an operation unit 220. The display control unit, the storage control unit, and the voice control unit may be integrally formed as the central control unit 208, or may be formed separately.

  The storage unit 200 stores time information, position information, and the like used when a stop determination unit 250 described later determines a stop state by a central control unit 208 described later. In addition, the storage unit 200 functions as an execution program storage unit 230, a map storage unit 232, an area data storage unit 234, a visit information storage unit 236, and a stop exclusion list storage unit 238 that register the processing of the navigation device 100. The execution program storage unit 230, the area data storage unit 234, the visit information storage unit 236, and the stop exclusion list storage unit 238 may be integrally formed as the storage unit 200, or may be formed separately. The map storage unit 232 stores map data for displaying a map on the display unit 204 in advance. The area data storage unit 234 stores area data such as POI data including genre information 240 indicating genres such as longitude, latitude, facilities, etc. of facilities, buildings, areas, etc. on the map in advance. The area data indicates information on the visit destination candidates derived by the visit destination candidate deriving unit 252 described later.

  Further, the central control unit 208 indicates that the passenger has visited at least the position of the predetermined area data, and stores the visit information associated with the visited area data in the visit information storage unit 236. The visit information can also include date and time information and a message when the passenger visits. Furthermore, the central control unit 208 causes the stop exclusion list storage unit 238 to store a stop exclusion list that is a list of position information such as longitude and latitude at positions where visit information is not stored even when the vehicle stops.

  The position acquisition unit 202 performs wireless communication with a GPS (Global Positioning System) satellite 290, acquires position information of a vehicle on which the navigation device 100 is mounted, and transmits the position information to the central control unit 208. Based on the position information, the central control unit 208 causes the display unit 204 to display the position of the vehicle on the map.

  The display unit 204 includes, for example, a liquid crystal display, an organic EL (Electro Luminescence) display, or the like. The central control unit 208 includes a map based on the map data 232, a position on the map of the vehicle based on the position information acquired by the position acquisition unit 202, a route to the destination set by the passenger, and a display unit 204. Various images are displayed on the display unit 204 in addition to the traffic congestion information of the road on the displayed map and one or a plurality of visiting site candidates derived by the visiting site candidate deriving unit 252 described later. Further, the display unit 204 superimposes a touch panel 210 described later on the surface thereof.

  When the facility in which the visit information is recorded in the visit information storage unit 236 is displayed on the display unit 204, the central control unit 208 displays the date / time information at the time of the visit and the text message recorded by the passenger through the touch panel 210 described later. Is created and displayed on the display unit 204. The passenger can display the recorded date information and message by selecting desired data from the list.

  With such a configuration, the passenger can leave not only the fact of the visit but also the date / time information at the time of the visit and an arbitrary message, and can accumulate more information about the visited place. For example, if it is a restaurant, it is possible to record the quality of the taste and refer to it later when eating out.

  The voice output unit 206 guides the destination direction of the vehicle by voice and outputs a question for the visit destination specifying unit 254 described later to specify a visit destination candidate. The voice output unit 206 is also input to the central control unit 208 from the voice input unit 212 described later, and outputs a voice message of a passenger stored in the visit information storage unit 236 described later by the central control unit 208. .

  The central control unit 208 controls the entire navigation device 100 according to the execution program stored in the execution program storage unit 230 by a semiconductor integrated circuit including a central processing unit (CPU). The central control unit 208 causes the display unit 204 to display a map based on the map data and a vehicle position based on the position information acquired by the position acquisition unit 202. Further, the central control unit 208 stores the visit information in the visit information storage unit 236 and the stop exclusion list in the stop exclusion list storage unit 238. In addition, the central control unit 208 sets a visited flag indicating that it has been visited in the area data corresponding to the visited facility. Further, the central control unit 208 includes a stop determination unit 250, a visit destination candidate derivation unit 252, a visit destination specifying unit 254, and a visit destination search unit 256.

  From the position information acquired from the position acquisition unit 202, the stop determination unit 250 determines whether or not the vehicle on which the navigation device 100 is mounted is in a stop state at a predetermined speed (about 0 km / h). If the stop determination unit 250 determines that the vehicle is in a stop state, the central control unit 208 causes the storage unit 200 to store the date and time at the time of stop and the position information acquired from the position information acquisition unit 202. The stop determination unit 250 acquires the date and time and position information when the vehicle is again at a predetermined speed or higher, the time difference between the date and time is equal to or longer than a predetermined time, and the distance between the position information differences is equal to or greater than a predetermined distance. In the case of, it is determined that the vehicle was stopped. Alternatively, the stop of the engine may be detected to determine that the vehicle is stopped.

  Furthermore, the navigation device 100 includes an acceleration sensor and a speed sensor, and the stop determination unit 250 does not receive the position information from the position acquisition unit 202 and makes a determination, but there is no output from the acceleration sensor or the speed sensor (acceleration or speed). The vehicle stop state may be determined based on the fact that the speed is zero.

  At this time, the stop determination unit 220 refers to the stop exclusion list stored in the stop exclusion list storage unit 238, and the position information acquisition unit 202 acquires one or more pieces of position information indicated in the stop exclusion list. If it coincides with the position information, the vehicle is not determined to be in a stopped state even if the vehicle stops at the position indicated by the position information and the elapsed time is equal to or longer than a predetermined time. Or, if the position acquired by the position information acquisition unit 202 is included in a predetermined range centered on one or more positions shown in the stop exclusion list, even if the vehicle stops for a predetermined time or more Not determined to be in a stopped state. As described above, in the present embodiment, the stop exclusion list is a list of position information that is not determined to be a stop state.

  If such a configuration is not adopted, even if there is no need to memorize the visited place, such as stopping a private car at the parking lot at home, etc., the visited place identifying unit 254 will try to identify the visited place. Troublesome work such as deletion of information occurs. In this embodiment, the passenger can register the location where there is no need to record the visit destination, such as the home, in advance in the stop exclusion list, so that the boarding can be performed for unnecessary recording work of the visit destination. It is possible to avoid a situation in which a person feels annoying.

  The visit destination candidate deriving unit 252 is an area existing within a predetermined range from the current position based on the position information of the stopped position acquired by the position acquiring unit 202 when the stop determining unit 250 determines that the stop is in the stopped state. One or more destination candidates for the passenger are derived from the data. The central control unit 208 causes the display unit 204 to display the list of candidates for the visit destination. For example, “family restaurant XXX”, “XXX park”, “XXX bowling alley”, and the like are derived as visited candidates, and a list of the visited candidates is displayed on the display unit 204.

  The visited site specifying unit 254 identifies the visited site visited by the passenger from the one or more visited site candidates derived by the visited site candidate deriving unit 252 through the touch panel 210 or the voice input unit 212.

  When specifying through the touch panel 210, a visit place is specified by the contact input of the passenger through the touch panel 210. By identifying the visit destination using the touch panel 210, the passenger simply visits the visit destination item among the visit destination candidates displayed on the display unit 204, and stores the visit information indicating the visit. It can be stored in the unit 236, the operation can be completed easily and in a short time, and the operation can be resumed.

  In addition, the voice output unit 206 outputs a question for specifying a visit destination candidate by voice, and the voice input unit 212 inputs the voice of the passenger's response to the central control unit 208, whereby the passenger's response to the question is answered. It is also possible to specify a place to visit based on. The central control unit 208 repeatedly outputs a plurality of questions about the visited site to the voice output unit 206 until the visited site specifying unit 254 can identify the visited site, so that the passenger can perform complicated manual work and visual recognition of the display unit 204. It is possible to specify a place to visit by simply answering verbally without performing the operation, and it is also possible to perform the departure work while recording the visit information. Therefore, the visit information can be stored with less burden.

  Further, when there are a plurality of visit destination candidates, the visit destination specifying unit 254 sets a priority for the visit destination candidates based on the current time. The central control unit 208 causes the voice output unit 206 to preferentially output a question about a visit destination candidate having a high priority.

  For example, during lunch time, restaurants that are likely to be open during the day are positioned higher than the candidates for the visit, and in the evening, sports gyms are positioned higher than the candidates for the visit. Focus on the most likely destinations at the stage. With such a configuration, it is possible to specify a visited place with fewer questions and responses, and the passenger can store the visit information with less burden.

  Similarly, when there are a plurality of visit destination candidates, the visit destination specifying unit 254 determines the approach direction to the stopped position calculated based on the position information acquired by the position acquisition unit 202 described later, and the direction of the vehicle at the time of stopping Accordingly, priority may be set for the visiting destination candidates, and the central control unit 208 may cause the voice output unit 206 to preferentially output questions about the visiting destination candidates with high priority.

  For example, a facility that has passed by the time of stopping is less likely to be a passenger's visit than a facility that has not passed. In addition, there is a high possibility that the facility ahead in the approach direction is a visited site. In the present embodiment, priority is set for the destination candidate based on the approach direction and the direction of the vehicle, and it is determined whether or not a visit is made from a destination candidate of a facility having a high priority, that is, a possibility that the passenger has visited. Check. With such a configuration, it is possible to specify a visited place with fewer questions and responses, and the passenger can store the visit information with less burden.

  FIG. 3 is an explanatory diagram showing an example of setting priorities of visiting destination candidates. It is assumed that the vehicle travels on the road as indicated by an alternate long and short dash line and stops at a position X in the figure. The facility C, the facility F, and the facility G have a low priority because the vehicle has passed in front of them. Moreover, since the facility B and the facility D are also located in the opposite lane, the priority is set low. That is, in this figure, facilities A and E are set with high priority as candidates for visiting destinations.

  The storage unit 200 stores a question in advance in association with the genre information 240 included in the area data. The visited site specifying unit 254 may select a question according to the genre information 240 of the visited site, and the central control unit 208 may cause the audio output unit 206 to output the selected question. For example, when a restaurant is listed as a candidate for a visit, the voice output unit 206 outputs a question asking about the impression of the meal, and when the passenger answers the impression of the meal, the visit is a restaurant. Can be identified. Further, if the visit destination candidate is a bowling alley, it is possible to specify the visit destination more reliably by asking a question according to the genre information 240 of the visit destination candidate such as outputting a question about the score.

  Furthermore, the central control unit 208 causes the visit information storage unit 236 to store the visit information indicating that the user has visited in association with the area data of the visit destination specified by the visit destination specifying unit 254 described later. The visit information includes date and time information at the time of the visit, a passenger's message input through the touch panel 210, and the like. When the visit information is associated with the area data corresponding to the facility displayed on the map, the central control unit 208 displays the color of the facility indicated by the area data displayed on the map, The pattern or shape is changed and displayed on the display unit 204. With this configuration, the passenger can easily see on the map whether the visitor has visited in the past, and can quickly reach the target information.

  FIG. 4 is a flowchart showing a flow of processing for changing the display of the facility corresponding to the area data associated with the visit information. When the central control unit 208 acquires area data such as a facility to be displayed on the display unit 204 from the area data storage unit 234 (S300), is the visit information associated with the area data stored in the visit information storage unit 236? It is confirmed whether or not (S302). When there is visit information (S302 YES), the central control unit 208 performs processing for changing the color of the facility or the like indicated by the area data (S304). Then, the central control unit 208 causes the display unit 204 to display a map showing the facilities corresponding to the area data using colors different from the others (S306).

  FIG. 5 is an explanatory diagram showing a display example of a facility or the like in which visit information is registered. In particular, FIG. 5A is an explanatory diagram showing a display example of a facility corresponding to area data associated with visit information, and FIG. 5B is stored in the visit information storage unit 236. It is explanatory drawing which showed the example of a display of the date information and message at the time of a visit contained in visit information.

  When the display unit 204 displays the facilities A and B where no visit information is stored in the visit information storage unit 236 and the facility C where the visit information is stored in the visit information storage unit 236, the central control unit 208 As shown in FIG. 5A, the facility C is displayed on the display unit 208 in an emphasized color (illustrated by hatching) that is easy to visually recognize. When the passenger touches the place where “facility C” is displayed on the touch panel 210, the central processing unit 208 causes the display unit 208 to display date and time information at least when the visit is made, as shown in FIG. At this time, if a voice message related to the facility C is stored in the visit information storage unit 236, the central processing unit 208 reads a sentence indicating that the voice message is stored, for example, “voice message exists” and “playback”. Characters are displayed on the display unit 204. The passenger can check the voice message stored in the past through the voice output unit 206 by touching the portion where “play” is displayed. If a text message related to the facility C is stored in the visit information storage unit 236, the central processing unit 208 displays a sentence indicating that the text message is stored, for example, “text message present” and “display”. It is displayed on the display unit 204. The passenger can check the text message stored in the past through the display unit 204 by touching the place where “display” is displayed.

  The visit destination search unit 256 searches the visit information storage unit 236 from the date / time information or the message for the keyword input by the passenger, and the facility corresponding to the date / time information or message corresponding to the visit destination corresponding to the keyword Etc. and make a list of them. The central control unit 208 causes the display unit 204 to display the list created by the visit search unit 256. With this configuration, the passenger stores the name of the dish that has left an impression on the facility or the like that he / she visited in advance as text via the touch panel 210 or a voice message input by the voice input unit 212, and the position is later Even if the memory of the facility name or the like becomes ambiguous, the area data of the visited place can be extracted and displayed by searching the name of the dish as a keyword. By selecting the area data, the passenger can specify the location of the visited place, the facility name, and the like, and can more reliably find the visited place.

  The touch panel 210 has various detection methods such as a resistive film method (pressure sensitive method), a capacitance method, an infrared light shielding method, an ultrasonic surface acoustic wave method, an electromagnetic induction method, an electrostatic coupling method, an acoustic pulse recognition method, and an image recognition method. Using the method, a user operation input corresponding to the display on the surface of the display unit 204 is received. For example, the touch panel 210 detects contact with a position corresponding to one or a plurality of visited candidates displayed by the central control unit 208 on the display unit 204. The passenger can input text to the central control unit 208 through the touch panel 210 by touching the characters displayed on the display unit 204.

  The voice input unit 212 inputs the passenger's voice to the central control unit 208. For example, the voice input unit 212 responds to a question output from the voice output unit 206 when the visit destination specifying unit 254 specifies a visit destination, or by a voice response made by a passenger or a voice when a visit is made. The message is input to the central control unit 208. The central control unit 208 causes the visit information storage unit 236 to store the date and time information at the time of the visit and the message input by voice through the voice input unit 212 as visit information. Thereafter, when the visit information is associated with the area data corresponding to the facility selected on the map, the central control unit 208 causes the display unit 204 to display the date and time information associated with the area data. Further, the central control unit 208 may cause the voice output unit 206 to output a voice message.

  With this configuration, the passenger can leave not only the fact of the visit but also the date / time information at the time of the visit and an arbitrary message, and can accumulate more information about the visited place. For example, in the case of an accommodation facility, it is possible to store impressions regarding bedding and the like and refer to it later when selecting an accommodation facility.

  FIG. 6 is a table explaining area data and visit information. In particular, FIG. 6A shows an example of area data, and FIG. 6B shows an example of visit information. The area data includes a unique area data ID, longitude, latitude, genre information 240, address, name, visited flag, and the like. The visit information includes a unique visit ID, date and time information (year / month / day, time) at the time of visit, a voice message stored through the voice input unit 212, a text message input through the touch panel 210, an area data ID, longitude, latitude Etc. are included. The data name stored as voice message or text message data may be an area data ID or a name including longitude and latitude. With this configuration, the central control unit 208 can more quickly check the visit information related to the area data.

  Since the visit information shown in FIG. 6B includes the area data ID of the visit destination, the central control unit 208 determines that the area data ID included in the visit information and the area data ID shown in FIG. Can be called, and all the matching items can be extracted, and the visited longitude, latitude, genre information 240, address, and name can be called.

  The navigation apparatus 100 can also include an external storage unit 214. The external storage unit 214 includes a detachable storage medium such as a USB (Universal Serial Bus) memory, an SD (Secure Digital) memory card, and a portable HDD (Hard disk drive). Further, the external storage unit 214 can function as a visit information storage unit 236, as with the storage unit 200. When the external storage unit 214 functions as the visit information storage unit 236, the passenger can easily retrieve the stored visit information from the navigation device 100 and connect to a personal computer or the like to update the blog on the Internet. It can be used for content when doing so.

  The central control unit 208 may store the visit information only in the external storage unit 214, or may store the visit information in both the external storage unit 214 and the storage unit 200. In the latter case, as an example, the central processing unit 208 causes the external storage unit 214 to store a copy of the visit information stored in the storage unit 200. The passenger can drive the vehicle equipped with the navigation device 100 and accumulate visit information even when the external storage unit 214 is removed. Thereafter, when the external storage unit 214 is connected to the navigation device 100, the central processing unit 208 updates the visit information in the external storage unit 214 with the visit information in the storage unit 200.

  In addition, when a passenger owns a portable terminal 292 having a function of acquiring and transmitting its own location information every predetermined time, and visiting the visited place while holding the portable terminal 292, A portable position acquisition unit 218, which will be described later, acquires position information of the portable terminal 292, and a visit destination specifying unit 224 specifies a visit destination based on the position information acquired by the portable position acquisition unit 218. With this configuration, the location information after the passenger gets off the vehicle can be acquired from the portable terminal 292 and the trajectory can be calculated, so that the visited place can be specified more accurately.

  At this time, the wireless communication unit 216 updates the content of the blog service by connecting to the Internet through the base station 294 or the like and uploading the visit information to a WEB server (not shown) on the Internet.

  The portable position acquisition unit 218 acquires position information of the portable terminal 292 from the portable terminal 292 owned by the passenger, and transmits the position information to the visited site specifying unit 254. With this configuration, the location information after the passenger gets off the vehicle can be acquired from the portable terminal 292 and the trajectory can be calculated, so that the visited place can be specified more accurately. Further, the portable position acquisition unit 218 may acquire the position information of the portable terminal 292 through Bluetooth (registered trademark), Zigbee, or WiMax. By using an existing wireless communication system, the navigation apparatus 100 can be manufactured at a lower cost.

  The operation unit 220 adjusts the volume of the sound output from the sound output unit 206 of the navigation device 100 and changes the screen for displaying the current position of the vehicle on which the navigation device 100 is mounted. Is transmitted to the central control unit 208. Although the same input can be performed using the touch panel 210 described above, the operation unit 220 can always perform a fixed operation regardless of the display content of the screen.

  As described above, by using the navigation device 100 according to the present embodiment, the passenger can leave the visit information indicating that he / she has visited without any troublesome operations. Then, when looking at destinations with the same purpose on the map, you can quickly find the target facilities by referring to the visit information, and conversely, avoid the facilities that were disappointing. It can also be determined. Furthermore, it is possible to store only a more significant visited place by eliminating a short time stop that does not need to be recorded, such as waiting for a signal or stopping at a vending machine.

  In addition, a program that functions as the navigation device 100 and a recording medium that records the program are also provided by the computer.

(Navigation method)
FIG. 7 is a flowchart for explaining the overall processing flow of the navigation device 100. The stop determination unit 250 determines from the position information acquired from the position acquisition unit 202 whether or not the vehicle on which the navigation device 100 is mounted has stopped at a predetermined speed (about 0 km / h) (S400). When the stop determination unit 250 determines that the vehicle has stopped (S400 YES), the central control unit 208 stores the time information and position information at that time in the storage unit 200 (S402). When the power of the navigation device 100 is ON (S404 YES), the navigation apparatus 100 waits while acquiring the position from the position acquisition unit 202 and monitoring the moving state until the vehicle starts moving again (S406 YES). When the vehicle starts to move (NO in S406), the difference time is calculated from the difference between the date and time when the vehicle is moving and the date and time when the vehicle is stopped, and the difference distance is calculated from the difference between the position when the vehicle is moving and the position when the vehicle is stopped. If it is larger and the difference distance is within the predetermined distance (YES in S408), a candidate for visit is derived (S414). If the difference time is within the predetermined time or the difference distance is greater than or equal to the predetermined distance (NO in S408), the stop state detection process (S400) is repeated.

  If the power of the navigation device 100 is OFF (S404 NO), the system waits until the power is turned ON (S410 NO). When the power is turned ON (S410 YES), the difference time and the difference distance are determined as in S408. (S412). If the difference time is within the predetermined time or the difference distance is equal to or greater than the predetermined distance (NO in S408), the process is repeated from the stop state detection process (S400). If the difference time is greater than the predetermined time and the difference distance is within the predetermined distance (S412 YES), a candidate for a visit is derived (S414). If the difference time is equal to or shorter than the predetermined time (NO in S412), the process is repeated from the stop state detection process (S400).

  When the mobile location acquisition unit 218 detects a wireless communication connection with the mobile terminal 292 (S416 YES), the mobile location acquisition unit 218 acquires location information from the mobile terminal 292 (S418). Subsequently, the visit destination specifying unit 254 refers to the location information from the mobile terminal 292, and if there is not, the visitor specifying unit 254 selects the visit location by answering the passenger's answer to the voice question or by selecting the passenger's touch panel 210. Specify (S420). Then, a voice or text message is stored as visit information (S422), and the process is repeated from the stop state detection process (S400).

  FIG. 8 is a flowchart for explaining the flow of processing in the visit destination specifying step (S420) in FIG. When the visited site specifying unit 254 acquires the visited site candidate derived by the visited site candidate deriving unit 252 (S500), the visited site identifying unit 254 determines whether the mobile location acquiring unit 218 has acquired the mobile location information (S502). When the mobile location information has been acquired (S502 YES), the location indicated by the mobile location information is specified as the visited location (S504), and the process is terminated. If the mobile location information has not been acquired (NO in S502), priorities are given to the visited candidates from the current time (S506). Furthermore, priority is given to a visit destination candidate from the approach direction and direction of the vehicle carrying the said navigation apparatus 100 (S508). Then, the visited candidate is displayed on the screen, and at the same time, a question for specifying the visited candidate is output from the voice output unit 206 (S510).

  If there is a cancel instruction from the passenger through the voice input unit 212 or the touch panel 210 (S512 YES), the process ends. If there is no cancellation instruction from the passenger (NO in S512) and there is an answer to the question through the voice input unit 212 (YES in S514), the visit destination is specified in the voice question format (S520). If there is no answer and there is an input from the touch panel (S516 YES), the visited place is specified by the input (S518). If there is no input from the touch panel (NO in S516), the process waits until there is a cancel instruction, an answer to the question, or input from the touch panel.

  Even in such a navigation method, it is possible to record the visited place with a simple operation and to improve the convenience of the passenger.
