  Subsequently, the operator operates the information terminal 12 a to transmit the input items to the information providing server 11 via the network 27. Then, the transmission / reception unit 14 receives transmission information from the information terminal 12a. At this time, the terminal specifying unit 16 extracts an ID key included in the transmission information, and specifies a personal file stored in the PIM database 21 corresponding to the information terminal 12a. Here, it is assumed that the personal file is created corresponding to the operator, and the ID key is information for specifying the operator.

  Further, the PIM processing unit 25 extracts items such as date / time, point, action schedule, and memo from the transmission information. In this case, the PIM processing unit 25 accesses the POI search unit 23 and acquires the position coordinates of the point. The PIM processing unit 25 selects and accesses the personal file specified by the terminal specifying unit 16 from the personal files stored in the PIM database 21, and stores the items in the personal file. . In this case, in the present embodiment, a date is extracted from the date and time, and items such as the date and time, a point (including position coordinates), an action schedule, and a memo are registered in association with the date. As a result, the schedule input by the operator is registered in the personal file corresponding to the operator stored in the PIM database 21.

  Next, the operator operates the information terminal 12b and confirms his / her schedule for the next month, for example. In this case, the operator transmits a schedule request from the information terminal 12 b to the information providing server 11 via the network 27. Then, the transmission / reception unit 14 receives transmission information from the information terminal 12b. At this time, the terminal specifying unit 16 extracts an ID key included in the transmission information, and specifies a personal file stored in the PIM database 21 corresponding to the information terminal 12b. Here, as described above, since the personal file is created corresponding to the operator, the ID key is information for specifying the operator.

  Then, the PIM processing unit 25 extracts matters relating to the schedule for the next one month from the specified personal file. Here, the items are items such as the operator's point, action schedule, and memo registered in association with the date. Then, after the data is converted in the transmission information creation unit 26, the item is transmitted from the transmission / reception unit 14 to the information terminal 12b. If the PIM program is not stored in the information terminal 12b, the PIM program is attached to the item and transmitted.

  Subsequently, the display control device of the information terminal 12b that has received the item causes the display device to display a schedule including the item as a schedule display screen 30 as shown in FIG. Here, the schedule display screen 30 displays a calendar 37 indicating the next month, for example, July 2001. Further, the schedule display screen 30 includes a title 31 of the schedule display screen 30, a current time (hour / minute) 32, and a last update date and time (year / month / day / date) that is the date and time when the schedule was last updated. Hour / minute) 33 and month (year / month) 34 indicated by the calendar 37 are included.

  Reference numeral 35 denotes date information for displaying date information indicated by a cursor 39, which will be described later. Reference numeral 36 denotes other items that can be displayed on the schedule display screen 30, for example, tags (identifiers) indicating registration points, notes, and the like. Reference numeral 38 denotes an icon displayed in a frame corresponding to each date on the calendar 37, and indicates that the destination and the action schedule are registered in association with the corresponding date.

Then, after the map is subjected to data conversion in the transmission information creation unit 26, it is transmitted from the transmission / reception unit 14 to the information terminal 12b and displayed on the display device of the information terminal 12b.

  The map creation unit 22 may create a map in advance when the schedule input by the operator is registered in the personal file. In this case, the PIM processing unit 25 extracts the destination and transmits it to the map creation unit 22. When the map corresponding to the point is created, the PIM processing unit 25 stores the map in the personal file of the operator in the PIM database 21 in association with the point and date. Thereby, when the matter regarding a schedule is transmitted to the said information terminal 12b according to the request | requirement from the information terminal 12b, the map created beforehand can also be transmitted. Therefore, even when the information terminal 12b does not store map information and does not have a map creation unit, the information terminal 12b immediately displays a map corresponding to the location as a map display screen 40. be able to.

  Further, facilities around the point may be searched and displayed on the map display screen 40. In this case, for example, when the operator inputs the type of facility related to the action schedule, the facility of the type existing around the point is searched. When the information terminal 12b stores POI information in a storage device and has a POI search unit, the information terminal 12b searches for a facility around the point and displays it on the display device.

  On the other hand, when the information terminal 12b does not store the POI information and does not have the POI search unit, the information terminal 12b requests the facility providing search together with the location to the information providing server 11 via the network 27. Send. Then, the POI search unit 23 of the information providing server 11 accesses the POI database 18 and searches for facilities around the point. Then, after the found facility is subjected to data conversion in the transmission information creation unit 26, it is transmitted from the transmission / reception unit 14 to the information terminal 12b and displayed on the display device of the information terminal 12b.

  The POI search unit 23 may search for a facility in advance when the schedule input by the operator is registered in the personal file. In this case, the PIM processing unit 25 extracts the points and the action schedule and transmits them to the POI search unit 23. When a facility of a type that exists in the vicinity of the point and is related to the action schedule is searched, the PIM processing unit 25 adds the facility and the date to the operator's personal file in the PIM database 21. Store in association with. Thereby, when the matter regarding a schedule is transmitted to the said information terminal 12b according to the request | requirement from the information terminal 12b, the facility searched beforehand can also be transmitted. Therefore, even when the information terminal 12b does not store POI information and does not have a POI search unit, the information terminal 12b immediately displays the facilities around the point on the map display screen 40. can do.

  Further, a route to the point may be searched and displayed on the map display screen 40. In this case, the route search is normally performed with the destination of the route as the point and the departure point as the home, but the destination and the departure point can be arbitrarily designated. When the information terminal 12b stores road information or the like in a storage device and has a route search unit, the information terminal 12b searches for a route to the point and displays it on the display device.

  On the other hand, when the information terminal 12b does not store road information or the like and does not have a route search unit, the information terminal 12b performs route search together with the points to the information providing server 11 via the network 27. Send a request. Then, the route search unit 24 of the information providing server 11 accesses the road database 19 and searches for a route to the point. Then, after the searched route is subjected to data conversion in the transmission information creation unit 26, it is transmitted from the transmission / reception unit 14 to the information terminal 12b and displayed on the display device of the information terminal 12b.

  The route search unit 24 may search for a route in advance when the schedule input by the operator is registered in the personal file. In this case, the PIM processing unit 25 extracts the point and transmits it to the route search unit 24. When a route corresponding to the point is searched, the PIM processing unit 25 stores the route in the personal file of the operator in the PIM database 21 in association with the point and date. Thereby, when the matter regarding a schedule is transmitted to the information terminal 12b in response to a request from the information terminal 12b, a route searched in advance can also be transmitted. Therefore, even when the information terminal 12b does not store road information and does not have a route search unit, the information terminal 12b immediately displays the route to the point on the map display screen 40. be able to.

  Here, the route search unit 24 accesses the traffic information database 20 when searching for a route, and considers the traffic information stored in the traffic information database 20 such as traffic jam information and traffic regulation information. You may search. Further, the route search unit 24 may search for a route by predicting the occurrence of a traffic jam based on the accumulated statistical information and scheduled event information. For example, a road around a station or a large commercial facility, and a specific time every day excluding weekends, for example, a scheduled time to pass through a road that is statistically confirmed to have traffic jams in the evening is the specific time. If so, a route that avoids the road is searched. In addition, traffic congestion is predicted around places where events such as festivals, parades, fireworks displays, etc. are scheduled, so a route that avoids roads around the places is searched.

  Furthermore, the route search unit 24 may search for a route based on weather information such as a weather forecast stored in the traffic information database 20. For example, when heavy rain is expected, a route that avoids mountain roads where slip accidents frequently occur may be searched.

  The information terminal 12b stores traffic information such as traffic jam information and traffic regulation information, accumulated statistical information and scheduled event information, weather information such as a weather forecast, etc. in a storage device, and a route search unit. If so, the information terminal 12b searches for a route in consideration of the traffic information, statistical information, event information, weather information, etc. without transmitting a route search request to the information providing server 11. be able to.

  When the operator designates the date indicated by the cursor 39, the information terminal 12b displays a map corresponding to the registered location on the display device, and traffic such as traffic jam information and traffic regulation information corresponding to the date. Information can also be displayed on roads on the map.

  In this case, the information terminal 12b transmits a traffic information request together with the location to the information providing server 11. Then, the route search unit 24 of the information providing server 11 accesses the traffic information database 20 to generate traffic congestion, traffic based on the accumulated statistical information about the road around the point and the scheduled event information. Predict traffic information such as regulations. In this case, traffic information such as occurrence of traffic congestion, traffic regulation, and the like is predicted in consideration of the day of the week, season, and time included in the action schedule corresponding to the date. Then, after the predicted traffic information corresponding to the date is converted into data in the transmission information creation unit 26, it is transmitted from the transmission / reception unit 14 to the information terminal 12b and displayed on the display device of the information terminal 12b.

  In addition, the predicted traffic information can be stored in the personal file of the operator in the PIM database 21 in association with the location and date.

  When the information terminal 12b stores traffic information such as traffic jam information and traffic regulation information, accumulated statistical information, scheduled event information, and the like in the storage device, the information terminal 12b provides information Traffic information such as the occurrence of traffic congestion and traffic regulation can be predicted without transmitting a traffic information request to the server 11.

  When the operator designates the date indicated by the cursor 39, the information terminal 12b displays a map corresponding to the registered point on the display device and also displays the weather forecast corresponding to the date on the road on the map. You can also

Is displayed. Thereby, the operator can easily grasp the contents of the schedule item 77 corresponding to the desired date and the point corresponding to the schedule item 77.

  Next, a third embodiment of the present invention will be described. The description of the same structure and the same operation as those of the first and second embodiments will be omitted.

  FIG. 10 is a first diagram showing a display screen of an information terminal in the third embodiment of the present invention, FIG. 11 is a second diagram showing a display screen of the information terminal in the third embodiment of the present invention, FIG. 12 is a flowchart showing the operation of the information terminal in the third embodiment of the present invention.

  In the present embodiment, when the information terminal has the current position detection device, the current position detected by the current position detection device is corrected based on the points registered as items related to the schedule. It has become. Thereby, even when the accuracy of the current position detection device is low, an accurate current position can be displayed on the map.

  Here, when the details of the input schedule are displayed on the display device of the information terminal 12b, a schedule details display 85 as shown in FIG. 10 is displayed. In FIG. 10, the schedule detail display 85 is displayed to the full screen size of the display device, but is displayed side by side with the map display screen as shown in FIGS. 1, 4, 8 and 9. You may do it. The schedule detail display 85 includes a scheduled date and time field 86 indicating the date and time corresponding to the schedule item, a name field 88 indicating the name of the spot corresponding to the schedule item, a memo field 89 indicating a memo about the schedule item, and the address of the spot. An address field 90 to be displayed, a TEL field 91 indicating a telephone number to be referred to, and an input date field 92 indicating a date on which a schedule item is input are included.

  Further, in the present embodiment, the display control device of the information terminal 12b displays a map 95 around the current position on the display device as shown in FIG. In FIG. 11, the map 95 is displayed to the full screen size of the display device. However, as shown in FIGS. 1, 4, 8, and 9, the map 95 is displayed side by side with the schedule display screen. May be. The map 95 includes a current position mark 96.

  In the information terminal 12b, the PIM processing unit 25 in the information providing server 11 selects and accesses the personal file of the operator of the information terminal 12b from the personal files stored in the PIM database 21. Check whether the schedule item corresponding to the time is registered.

  Here, in the example shown in FIG. 10, since the date and time corresponding to the schedule item is 13:00 on September 13, 2001, the PIM processing unit 25 is 13:00 on September 13, 2001. Until it becomes, it is repeatedly checked whether or not the schedule item corresponding to the current time is registered. When the current time becomes September 13, 2001, 16:00, the PIM processing unit 25 determines that the schedule item corresponding to the current time is registered, and the point corresponding to the schedule item is determined. The name, that is, ΔΔ station is extracted. Subsequently, the PIM processing unit 25 accesses the POI search unit 23 and acquires the position coordinates of ΔΔ station as a point corresponding to the schedule item. Then, the position coordinates of the ΔΔ station are transmitted to the information terminal 12b.

  Then, the information terminal 12b determines whether or not the distance between the ΔΔ station as the point corresponding to the received schedule item and the current position detected by the current position detection device is equal to or less than a predetermined value. If it is determined that the schedule position is equal to or less than the predetermined value, the schedule position is estimated to be the correct current position, the current position is corrected, and the schedule position is matched. This is because the position coordinates of the point corresponding to the schedule item based on the map information are considered to have less error than the current position detected by the current position detection device of the information terminal such as the information terminal 12b. When the distance between the current position detection device and the current position detected by the current position detection device is equal to or smaller than the predetermined value, the information terminal 12b can actually estimate that the information terminal 12b exists at the point corresponding to the schedule item. It is. That is, it can be assumed that the operator is acting according to the schedule. As a result, the current position mark 96 in the map 95 around the current position of the information terminal 12b is corrected to the position 97 of ΔΔ station as the point corresponding to the schedule item.

  If it is determined that the distance between the station corresponding to the schedule item and the current position detected by the current position detection device is not less than a predetermined value, the information terminal 12b detects the current position detected by the current position detection device. Is assumed to be the correct current position, and the current position is not corrected. This is because if the distance between the point corresponding to the schedule item and the current position detected by the current position detection device is greater than a predetermined value, the information terminal 12b may infer that the information terminal 12b does not exist at the point corresponding to the schedule item. Because it can. That is, it can be assumed that the operator is not acting according to the schedule.

  When the information terminal 12b includes the PIM processing unit 25, the PIM database 21, the POI search unit 23, etc., the above-described operations are all performed without communicating with the information providing server 11. 12b can be performed alone.

Next, a flowchart will be described.
Step S1: It is determined whether or not a schedule item is registered at the current time. If it is registered, the process proceeds to step S2. If it is not registered, the check is repeated until it is registered.
Step S2: It is determined whether or not the distance between the point corresponding to the schedule item and the current position is equal to or less than a predetermined value. If it is equal to or smaller than the predetermined value, the process proceeds to step S3.
Step S3: The point corresponding to the schedule item is estimated as the current position, and the current position is corrected.
Step S4: The position detected by the current position detection device is estimated as the current position.

  As described above, in the present embodiment, when the information terminal 12b has the current position detection device, the current position detected by the current position detection device is corrected based on the point corresponding to the schedule item. It has become. Thereby, even when the accuracy of the current position detection device is low, the accurate current position can be displayed on the map, and the operator can easily grasp the accurate current position.
