BACKGROUND OF THE INVENTION
  The present invention relates to a portable information terminal that is carried by an individual and used to manage work items that the user must do, and in particular, stores work items that must be carried out at a specific point or facility. A portable information terminal that performs processing such as notifying the user by detecting approaching or leaving the facility and notifying the user, or notifying the person other than the user of the position and status by performing communication.And its navigation methodAbout.
[0002]
[Prior art]
The conventional portable information terminal has a function (so-called action list) for specifying and recording the start date, deadline date, and importance of the work item in order to manage the work item that the user has to do. There was something installed. The user displays unprocessed work items in the action list in descending order of importance, and sometimes checks whether the deadline has passed so that the user can remember the work items. Also, at the time of confirmation, a work item that has already been completed is checked and excluded from the unprocessed work item list.
[0003]
In addition, in order to manage a schedule, a conventional portable information terminal stores a schedule by designating a date and time, and notifies a user (alarm) in order to remind the date and time of the schedule (so-called alarm). , Schedule) was installed. The user was reminding the user that there was a plan by using the schedule to check if the specific date and time were already filled in the schedule, or by making an alarm sound to inform the scheduled time. . In addition, the schedule and the action list are linked, and there is a work item displayed on the schedule from the start date to the deadline date.
[0004]
On the other hand, various techniques shown below have been proposed as a technique for associating and processing a schedule and a place.
[0005]
For example, an apparatus described in Japanese Patent Application Laid-Open No. 10-124464 (hereinafter referred to as Document 1) is an information processing apparatus having a communication function, and a schedule including scheduled start time, location, and partner data is registered in advance. Keep it. Then, by acquiring the current position and the current time, if it is determined that you are at a point far from the planned location and do not reach the planned location by the start time, a message is sent to the other party registered in the schedule. It is supposed to send.
[0006]
Japanese Patent Laid-Open No. 10-187625 (hereinafter referred to as Document 2) is a schedule management system, which includes schedule information input means for inputting schedule information from each user, and the current position of each user. A position detection means for detecting a predetermined message, a notification means for notifying each user of a predetermined message, a clock means having a calendar function, and a management means, the time information of the current time and the schedule information substantially match, and A predetermined message is transmitted to the user when the preset location does not match the current location.
[0007]
Moreover, as a prior art regarding the position display system, there is an information processing apparatus described in Japanese Patent Laid-Open No. 2000-112347 (hereinafter referred to as Document 3). This information processing apparatus displays map information including place name information indicating a specific point, extracts place name information from the map information, and stores place name information corresponding to target information such as a name input by the user and service contents. When it is determined that the point indicated by the place name information extracted from the map is close to the point indicated by the stored place name information, notification is made or target information is displayed.
[0008]
[Problems to be solved by the invention]
However, since there is no means for notifying the user of the conventional action list, there is a problem that even if the user approaches the place where the work should be performed, the user passes by without knowing the work item.
[0009]
In addition, the normal schedule can be notified at a specific date and time, or the documents 1 and 2 can be notified when the user is not registered at a specific date and time. There is a problem that it is not possible to use it when it is a work that may be connected to a specific place.
[0010]
In the case of Document 3, since the place name information must be included in the map information, the user must always enter the place name of the target information, and the place name of the target information cannot be input. There was a problem that was not available.

FIG. 5 is a flowchart for explaining processing for notifying and displaying memo information when it is determined that an approach has been made and approached. The processing procedure will be described below with reference to the flowchart shown in FIG.
[0036]
In step S11, the current position is acquired by the current position acquisition means 11, and in step S12, it is checked whether or not it has been acquired. As a result, when the current position cannot be acquired (when No is determined in step S12), the process returns to step S11. On the other hand, when the current position can be acquired (when it is determined Yes in step S12), the operation proceeds to step S13 to acquire a set value such as the longitude and latitude of the set point, and in step S14, the set value is set. Check if the value was obtained. As a result, if all the set values have been extracted and no further set values can be extracted, the process ends.
[0037]
On the other hand, when the set value can be acquired (when it is determined Yes in step S14), the operation proceeds to step S15, and it is checked whether the distance between the current position and the set point is equal to or less than the threshold value. As a result, if it is larger than the threshold value, the operation returns to step S13, and if it is less than the threshold value, the operation proceeds to step S16. In step S16, the user is notified that the current position has approached the set point by using an LED and a buzzer (including vibration), and the memo information is taken out from the storage means 14a and displayed on the display means 12 according to the memo type. Display and return to step S13. In this processing, since the determination is performed until the set value cannot be extracted, a plurality of set values can be set.

This will be specifically described below.
[0040]
  FIG. 6 shows this embodiment.StateIt is a block diagram which shows the electric constitution of the portable information terminal 10b.
[0041]
  The mobile information terminal 10b receives a radio wave from a GPS satellite and calculates current position acquisition means 11 for calculating the position information of the terminal 10b, an input means 13b such as a button or a key, an input set point, memo information, It comprises at least a storage means 14b for storing telephone numbers and mail addresses, a communication means 17 for sending mails and short messages, and a control means 16b for controlling the operations of these means. Other functional blocks may include display means, notification means, batteries, etc., but the operation of these functional blocks isStateHowever, since it is not important, illustration is omitted here.
[0042]
  This embodimentStateIn this case, the input unit 13b is a button, a key, or the like, and is configured to store the longitude and latitude of the current position acquired by the current position acquisition unit 11 in the storage unit 14b by key operation. This is the embodimentIn stateIs because it does not have a display means that can withstand the display of the map, and if there is a display means such as a fine liquid crystal panel,Reference exampleAs shown in FIG. 1, a map may be displayed on the display unit 14a, and the cursor may be moved with a tablet or a key to indicate a point on the map.
[0043]
  In addition, this embodimentStateThe storage means 14b is composed of, for example, a random accessible RAM, and stores the latitude / longitude of the set point, a telephone number, a mail address, memo information, and the like. However, a rewritable flash ROM may be used.
[0044]
  This embodimentStateThe communication means 17 for transmitting and receiving short messages and e-mails is realized as a wireless communication module, and the inside thereof is, for example, an antenna, an oscillation circuit, a modulation circuit, a central processing unit (CPU), a protocol processing stack, and a message. It is composed of a ROM that is a read-only memory that stores transmission / reception application programs and the like, and a RAM that is a random access memory that temporarily stores data used for processing. The detailed explanation is given in this embodiment.In stateIs not particularly important and is omitted here. Further, the communication means 17 does not need to be built in the portable information terminal, and the portable information terminal may be provided with an external card slot, and a wireless module may be inserted into the slot so that communication is possible.
[0045]
  In addition, this embodimentStateThe control means 16b includes, for example, a central processing unit (CPU), a ROM that is a read-only memory that stores a control program, and a RAM that is a random access memory that temporarily stores data. The storage unit 14b may be a part of the ROM or RAM of the control unit 16b.
[0046]
FIG. 7 is a chart showing an example of setting value data stored in the storage unit 14b. That is, it has the latitude and longitude of the set point, the threshold A, the threshold B, the telephone number, the mail address, and the memo as elements. For example, the setting point is 140.140 degrees east longitude and 35.057 degrees north latitude, the threshold value A for approach determination is 10 meters, the threshold value B for determination of distance is 30 meters, and it is shorted to a mobile phone with a number of 090-1234-XXXX. Send a message, address XXXX @ AAA. ne. Send an email to jp.
[0047]
FIG. 8 is a flowchart for explaining a process of transmitting memo information when it is determined that the user has moved away from the set point after determining that the user has approached the set point. The processing procedure will be described below with reference to the flowchart shown in FIG.
[0048]
In step S21, the current position is acquired by the current position acquisition unit 11, and in step S22, it is checked whether it has been acquired. As a result, when the current position cannot be obtained (when No is determined in step S22), the process returns to step S21. On the other hand, if the current position can be acquired (if determined as Yes in step S22), the operation proceeds to step S23 to acquire a set value such as the longitude and latitude of the set point. In step S24, the set value is set. Check if the value was obtained. As a result, if all the set values have been extracted and no further set values can be extracted, the process ends.
[0049]
On the other hand, when the set value can be acquired (when it is determined Yes at step S24), the operation proceeds to step S25 to check whether the approach flag is set. If the approach flag is set (if determined as Yes in step S25), the operation proceeds to step S28, and if the approach flag is not set (if determined as No in step S25). Advances the operation to step S26.
[0050]
In step S26, it is checked whether the distance between the current position and the set point is equal to or less than a threshold value A.
Then, if it is larger than the threshold A (if determined No in step S26), the process returns to step S23, and if it is equal to or less than the threshold A (if determined Yes in step S26), the operation proceeds to step S27. In step S27, an approach flag is set and the process returns to step S23.
[0051]
On the other hand, in step S28, it is checked whether the distance between the current position and the set point is greater than or equal to the threshold value B. If it is smaller than the threshold value B (No in step S28), the process returns to step S23, and if it is greater than or equal to the threshold value B, the operation proceeds to step S29, the approach flag is cleared, and the telephone number and mail address are set. The memo information is transmitted to the process, and the process returns to step S23.
[0052]
Here, the threshold value B is larger than the threshold value A. For example, when a retail store is considered as the set point, the threshold A may be as small as 10 meters and the threshold B may be as small as 30 meters. However, when considering the platform of the station, the threshold A is 50 meters and the threshold B. Needs to be as large as 100 meters. In the processing operation described above, notification is not performed, but notification means such as a buzzer, an LED, or a vibration member may be provided to notify the user during communication.
[0053]
  This embodimentStateAccording to the portable information terminal 10b, for example, when a company is set as a set point and the telephone number of the home is stored in the storage unit 14b, it is possible to automatically call the home and notify the return home when leaving the company. In addition, a child of an age that is difficult to make a call by himself / herself can have the portable information terminal 10b to inform a parent of returning home from a kindergarten, an elementary school or a cram school.

In step S31, the current position is acquired by the current position acquisition unit 11, and in step S32, it is checked whether the current position has been acquired. As a result, when the current position cannot be acquired (when it is determined No in step S32), the process returns to step S31. On the other hand, when the current position can be acquired (when it is determined Yes in step S32), the operation proceeds to step S33, and it is checked whether or not the search range has been exceeded.
[0062]
As a result, if it is out of the search range (if it is determined Yes in step S33), the operation proceeds to step S34, and if it is not out of the search range (if it is determined No in step S33), it proceeds to step S35. And proceed with the operation.
[0063]
In step S34, the server location database is searched in the new search range, and in step S35, setting values such as longitude and latitude of the object obtained by the search are acquired. In the next step S36, it is checked whether or not the set values have been acquired. If all the set values have been extracted and cannot be extracted any more, the process ends.
[0064]
On the other hand, when the set value can be acquired (when it is determined Yes in step S36), the operation proceeds to step S37, and it is checked whether the distance between the current position and the set point is equal to or less than the threshold value. As a result, if it is larger than the threshold value, the operation returns to step S35, and if it is less than the threshold value, the operation proceeds to step S38. In step S38, the user is informed that the current position has approached the set point by using an LED and a buzzer (including vibration), the memo information is taken out from the storage means 14c, and is displayed on the display means 12 according to the memo type. Display and return to step S35.
