2. Description of the Related Art In recent years, systems using GPS have been used in various fields. For example, in a car navigation system for a car, a current position is acquired by using GPS, map information is read from a CD-ROM or the like, and based on the position information acquired by GPS, the current position of the car. Is displayed by displaying a map on the screen. As the car moves, the road map displayed on the screen is updated, and a map around the road can be displayed.

In recent years, there have been some watches that have a built-in GPS function in a watch that is much smaller than the above-mentioned vehicle-mounted type. For example, Casio Computer Co., Ltd.'s "GPS built-in watch" PROTREK SATELLITE NAV
I "] and JP-A-8-122093.

The "GPS built-in watch" PROTREK SATELLITE NAVI "" of Casio Computer Co., Ltd. stores start-up data distributed from a satellite in a memory, and stores this data in a current location based on an area and time registered in advance. Is assumed. When acquiring data, continuous measurement can be performed. For example, month, day, hour, minute, latitude, and longitude as start-up data can be acquired every 10 minutes and stored in the memory.

[0005] In Japanese Patent Application Laid-Open No. 8-122,093, the time and the location point of the position detecting device at that time are stored in an IC card mounted on the portable position detecting device every predetermined time (one minute). Thus, the time series data of the time and the location point is created. Next, the daily report creation support device divides the time series data of the time and the location point created in the IC card into a time zone in which the position detection device is moving and a time zone in which the location detection device is stationary. For the stationary time zone, based on the position information, the corresponding map information (for example, “@Sangyo Co., Ltd. XX branch office”) is stored in the CD-R.

FIG. 2 shows an example of the data structure of a table storing the longitude / latitude, its effective range, and the place (place name) according to the present invention.

This table 31 has a latitude 31a and a longitude 3
1b, an area 31c, a type 31d, a flag 31e, and a place (place name) 31f. In the example shown in FIG. 2, the data (101-1) of ten points
To 31-10) are registered in the table 31. Each data of this table 31 can be edited using an editor. The first nine locations (data 31-1
) To 31-9), the user has input an appropriate place name (for example, “home”). When the data is acquired, the date and time (09/01/01) are set as default values for the last place (data 31-10).
18:56) is temporarily set as a place name.

Here, N at latitude 31a represents north latitude and south latitude is represented by S. Similarly, E at longitude 31b represents east longitude, and west longitude is represented by W. For example, in the first data 31-1 in FIG.
43820 is north latitude 34 ° 38'20 ″ (hereinafter, degrees, minutes,
The notation of the second is represented by °, ', ″, respectively, where 1 ″ corresponds to about 30 m. Also, E13548
20 represents 135 ° 48'20 ″ east longitude, where 1 ″
Corresponds to about 25 m.

The area 31c is the distance from a point to the north, south, east, west, and east, which is represented by m. The default value is set to 100, and at that time, the inside of a 200 m square is the place. The value of the area 31c can be changed by an editor. It is desirable that the value of the area 31c be converted into ° ′ ″ (degree / minute / second) in advance when the program is started.

The type 31d is a type of a method for obtaining data in the file 32, and is obtained when the user enters a location within the range defined by the area 31c around a point indicated by the latitude 31a and the longitude 31b. The default value is 1 for things, 2 for things you get when you leave, 3 for things you get on entering and leaving, 0 for things you don't.
And

The flag 31e includes a latitude 31a and a longitude 31b.
Is set to 1 when it is located within a range defined by the area 31c around the point indicated by, and is set to 0 when it is not.

For example, in FIG.
In the case of 1-7, the location is "Tokyo" from the data of the latitude 31a and the longitude 31b, the value of the area 31c is 10000 m, and in the case of the eighth data 31-8, the location is from the data of the latitude 31a and the longitude 31b. In "Shinjuku", the value of the area 31c is 1000 m, and in the case of the ninth data 31-9, the location is "Tokyo" from the data of the latitude 31a and the longitude 31b, and the value of the area 31c is 200m. Therefore, assuming that the user is currently in the location within the “Tokyo” area of the ninth data 31-9, the values of the seventh to ninth flags 31e are all “1”. Next, the value of the ninth flag 31e changes to 0 if the value comes out of the “Tokyo” range, and the value of the eighth flag 31e changes to 0 if the value comes out of the range of “Shinjuku”. When the value finally changes from the range of "Tokyo", the value of the seventh flag 31e is also 0.
Changes to

The data of each item in the table 31 can be edited except for the flag 31e.
Therefore, if the latitude and longitude can be checked, the data of the unknown point can be stored in advance.

FIG. 3 shows an example of the data structure of a file storing information relating to the date / time and location (location name) at which the location information was obtained and information on entering and exiting the location according to the present invention.

This file 32 has a date 32a, a time 3
2b, entry / exit 32c to the place, and place (place name) 32d. In the example shown in FIG.
Data of ten points (32-1 to 32-10) is registered in the file 32. Data acquired by GPS is added to this file 32 in units of one line.
The date 32a and the time 32b are at the time when the data is acquired, and are within the range defined by the area 31c around the point indicated by the latitude 31a and the longitude 31b acquired and registered in the table 31 at that time. Are entered, and those that come out of the area are displayed as out. The place (place name) 32d is a place (place name) 31f in the table 31.

For example, in FIG. 3, the tenth data 32-10 is the latest data, and the date 32a is 09 /
01, the time 32b is obtained at 18:56, and a certain place is obtained in the table 31. The information in the file 32 can be referred to later as a behavior memo, and can be edited to be a report or a diary.

FIG. 4 is a diagram showing a display example on the display device during which the processing according to the present invention is being executed.

The data items displayed on the display device 5 include the date and time stored in the file 32 of FIG.
Time, entry / exit, and place (place name). Here, data is displayed in units of one line. However, it is not necessary to be limited to one line. In the case of FIG. 4, the data 5-10 displayed last is the latest data.

First, by starting the process, the GPS receiver 7 is operated to measure the current position (step S).
101). Next, data stored in the table 31 is checked in order from the head to the tail (step S102). As a result of the search, it is determined whether there is remaining data (step S103). If there is no remaining data, wait for time (step S104), here wait for about 10 minutes, return to step S101, operate the GPS receiver 7 again, and measure the current position. On the other hand, if there is remaining data, it is determined whether or not the current position acquired in step S1 is within the area of the data (step S105).

If it is within the area, it is determined whether the data flag is 1 (step S10).
6). If the flag is 1, since the player has already entered the area, the process returns to step S2 without doing anything. Flag is 1
If not, the flag is changed to 1 (step S10).
7). Further, it is determined whether the type is 1 or 3 (step S108). If the type is not 1 or 3, nothing is performed and the process returns to step S102. If the type is 1 or 3, a line feed code is added to the data consisting of month, day, time, entry / exit, and location (location name), and the data following the data stored at the end of the file 32 is added. Is added to the display device 5 as the latest data (step S112).
Is displayed as the latest data (step S113), and the process returns to step S102.

On the other hand, if the data is not within the area in step S105, it is determined whether or not the flag of the data is 0 (step S109). If the flag is 0, it has already left the area, and the process returns to step S2 without doing anything. If the flag is not 0, the flag is changed to 0 (step S110). Further, it is determined whether the type is 2 or 3 (step S111).
If the type is not 2 or 3, the process returns to step S102 without doing anything. If the type is 2 or 3, a line feed code is added to the data consisting of the date, time, entry / exit, and location (location name), and the data following the data stored at the end of the file 32 is added. Then, the data acquired this time is added as the latest data (step S112), and the acquired data is displayed on the display device 5 as the latest data (step S113), and the process returns to the step S102.

For example, in FIG. 3, the tenth data 32-10, "Month / Date 09/01, Time 18:
56, in / out, location 09/01 18:56 "corresponds to the latest data.

FIG. 6 is a flow chart for explaining a flow for acquiring data of a place in a table at a place, which is a part of the processing in the present invention. Specifically, on the display screen of FIG.
It is a flowchart for demonstrating the operation at the time of touching.

First, the current position is measured by operating the GPS receiver 7 (step S201). Next, in order to create data relating to the items constituting the table 31 shown in FIG. 2, latitude 31a, longitude 31b, area 31c, type 31d, flag 31e, and place (place name) 31f,
The data of the current position acquired from the GPS receiver 7 is stored in the latitude 31a and the longitude 31b, and the default values 100, 1, and 1 are stored in the area 31c, the type 31d, and the flag 31e, respectively. The provisional data is added as the data including the date and time at that time, and the data to which a line feed code is added is added as the latest data next to the last data stored in the table 31 (step S202). Further, in order to create data relating to the date 32a, time 32b, entry / exit 32c to the area, and place (place name) 32d of the items constituting the file 32 shown in FIG. The date / time data obtained from
2b, the entry / exit 32c to the area is determined based on the data registered in the table 31 and the temporary data of the place (place name) 32d is converted into data ( This data is the same as the data registered in the location 31f of the item in the table 31), and the data to which the line feed code is added is added to the file 3.
2 is added as the latest data next to the last data stored in step 2 (step S203). Finally file 3
2 is displayed on the display device 4 as the latest data (step S204), and the process is terminated.
The processing in step S203 is performed based on the contents described in the description of FIG.

For example, in FIG. 4, the last displayed data 5-10, "Month / Date 09/01, Time
18:56, entry / exit, location 09/01 18: 5
"6" corresponds to the latest data.
