Description

  The present invention relates to a portable terminal, an information processing method, and a program to be executed by a computer.

  Users of mobile terminals such as mobile phones and PHS (Personal Handy-phone System) often notify other people of the business mainly by e-mail unless they are in a hurry. For example, when multiple people gather at a predetermined date and time, such as a meeting, when it is known that it will be delayed earlier than the meeting time, e-mail the expected arrival time at the meeting place to the representative You can notify at. When it is known that the time is close at the meeting time, it is highly likely that the representative will be notified to the representative by telephone, not by e-mail, in order to quickly and reliably notify the delay.

  An example of a mobile information terminal that makes it possible to notify an expected arrival time of a destination to a waiting party is disclosed in Patent Document 1. In the method disclosed in this document, when the mobile information terminal detects the current location, calculates the estimated arrival time of the destination, and when the estimated arrival time is later than the waiting time, the user enters the mobile information terminal. By inputting the estimated arrival time, the mobile information terminal notifies the opponent terminal of the estimated arrival time.

The network 30 shown in FIG. 2 includes devices such as a mail server that controls transmission / reception of electronic mail and a router that forwards packets to a destination. However, these devices are not shown in FIG. .

  Next, each configuration of the mobile terminal 10 shown in FIG. 1 will be described in detail. Here, it is assumed that the mobile terminal 10 shown in FIG. 1 is the mobile terminal 10a shown in FIG. 2, and the other mobile terminal that transmits and receives e-mails to and from the mobile terminal 10a is the mobile terminal 10b.

  The wireless communication unit 11 transmits and receives e-mails to and from other mobile terminals via a base station connected to the network 30. The storage unit 13 is a message informing the arrival schedule corresponding to the waiting information including information of the destination, the meeting time and the e-mail address, the information of the map in which the destination is written, and the distance from the destination. And a table in which are described. The position information acquisition unit 12 acquires position information indicating the current position in the map stored in the storage unit 13 according to an instruction from the control unit 15 and notifies the control unit 15 of the position information. In the following description, the position information is coordinate information having latitude and longitude as coordinates. However, the position information may be determined by defining other coordinates.

  The control unit 15 causes the position information acquisition unit 12 to acquire position information at regular intervals until the date and time of the waiting information is reached, and calculates the distance between the position information and the destination each time the position information is acquired. To do. And the control part 15 reads the message corresponding to the calculated distance from the table in the memory | storage part 13, produces | generates the electronic mail containing a message, and transmits to the e-mail address contained in waiting information. When the e-mail address included in the waiting information is the address of the mobile terminal 10b, the control unit 15 transmits the e-mail to the mobile terminal 10b.

  In addition, when receiving an e-mail with the e-mail address included in the waiting information as a transmission source, the control unit 15 causes the display unit 14 to display a message included in the e-mail. When the e-mail address included in the waiting information is the address of the mobile terminal 10b, the control unit 15 causes the display unit 14 to display an e-mail message received from the mobile terminal 10b.

  In the flowchart shown in FIG. 3, the processing of step 1007 and step 1008 is shown to be executed after step 1006, but it may be executed anywhere between step 1002 and step 1006.

  According to the present embodiment, when approaching the date and time of waiting for each member, the waiting time is a guideline for how long it will arrive at the meeting place without operating the mobile terminal by itself. Can be transmitted to the mobile terminals of other members. In addition, when an e-mail from another member is received, it is possible to check on the screen of the display section how long the other member can go to the meeting place without operating the portable terminal. Below, the embodiment of the portable terminal of the present invention is described in detail.

(First embodiment)
The configuration of the mobile terminal of this embodiment will be described. Similarly to the mobile terminal 10 shown in FIG. 1, the mobile terminal of the present embodiment also transmits and receives data in packets according to IP with other mobile terminals via the Internet.

  FIG. 4 is a block diagram illustrating a configuration example of the mobile terminal according to the present embodiment. As illustrated in FIG. 4, the mobile terminal 50 includes a communication unit 110, a position information acquisition unit 12, a storage unit 13, a display unit 14, an operation unit 16, an acceleration sensor 17, and a control unit 15. . The communication unit 110 includes a short-range communication unit 111 and a wireless communication unit 112. The control unit 15 includes a schedule management unit 151, a clock unit 152 that measures time, an e-mail control unit 153, and a movement prediction unit 154.

  The control unit 15 includes a CPU (Central Processing Unit) (not shown) that executes processing according to a program, and a memory (not shown) for storing the program. The clock unit 152 is configured by a dedicated circuit, but each of the schedule management unit 151, the email control unit 153, and the movement prediction unit 154 is virtually configured in the portable terminal 50 by the CPU executing a program. The Note that some or all of the schedule management unit 151, the e-mail control unit 153, and the movement prediction unit 154 may be configured by a dedicated circuit.

  The wireless communication unit 112 of the communication unit 110 corresponds to the wireless communication unit 11 illustrated in FIG. 1 and is connected to the Internet via a base station. The wireless communication unit 112 may be a communication unit for PHS (Personal Handy-phone System), or may be a communication unit for a macro cell in which the communication range of one base station is wider than PHS. The base station may be a wireless LAN (Local Area Network) access point.

  The display unit 14 is a liquid crystal display or an organic EL (electroluminescence) display. The near field communication unit 111 is a communication unit for NFC (Near Field Communication) such as Bluetooth (registered trademark), FeliCa (registered trademark), and infrared communication.

  The storage unit 13 stores information on a map in which main place names and building names are described using latitude and longitude as coordinates. The place name and the building name are, for example, the name of a transportation station or stop, the name of a tourist place such as Tokyo Tower and Sensoji Temple, and the name of a store such as XX department store and XX restaurant.

  The storage unit 13 stores waiting information. The meeting information includes information on a meeting place designated as a meeting place (hereinafter referred to as a destination), a meeting date and time, an address of a mobile terminal of a member who gathers at the meeting place, and a message exchange time. The message exchange time is a time for determining the time to start exchanging notifications of arrival schedules at the meeting place by calculating backward from the meeting date and time. For example, if the meeting date and time is set to 5 pm on March 1, 2011 and the message exchange time is set to 2 hours, the arrival schedule will be sent to other members by e-mail when it is 3 pm on March 1, 2011. Start notification to.

  The range of the map stored in the storage unit 13 is, for example, a range having a radius of 10 kilometers centered on the destination designated as the meeting place. Further, the storage unit 13 stores a table in which a message notifying the arrival schedule corresponding to the distance d from the destination to the current position is described. FIG. 5 shows an example of a table stored in the storage unit shown in FIG.

  In the table shown in FIG. 5, a message is described corresponding to the distance d. In the table shown in FIG. 5, a message is described corresponding to the moving speed v (km / h) in consideration of a moving means other than walking. Among the means for moving to the meeting place, a means other than walking can be a bicycle, a car, a train, or the like. In the table shown in FIG. 5, in order to simplify the explanation, there are two cases where the moving means is walking (v ≦ 5 km / h) and other cases (v> 5 km / h). In FIG. 5, in the case of walking, it is set based on information that the speed of an adult male is about 4 km / h. However, the method for determining whether or not the moving means is walking is not limited to this method.

  In addition, in FIG. 5, when 5 km ≦ d ≦ 7 km, the message is the same regardless of the moving speed because it is impossible to come to the meeting place on foot from a distance of 5 km or more. The message is set in one way, assuming that the moving means is used. For 100 m ≦ d ≦ 200 m, the message is the same when the moving means is walking and when it is not walking. The reason will be explained. When using a moving means other than walking, if the distance to the meeting place is 200 m or less, the possibility of switching from the moving means to walking increases. It is considered that it takes time to put a bicycle in a bicycle parking lot when switching the means of transportation from bicycle to walking. It is considered that it takes time to pass through a crowded ticket gate when switching from a train to a walking means. It is thought that it takes time to give and receive money when the means of transportation is switched from taxi to walking. Thus, the message of the person who has the possibility of switching the transportation means is set to the same message as the person who is walking and waiting.

  In addition, when each of the schedule management unit 151, the email control unit 153, and the movement prediction unit 154 is virtually configured by the CPU executing the program, the schedule management unit 151, the email control unit 153, and Application software programs corresponding to each of the movement prediction units 154 are stored in the storage unit 13 in advance.

  The position information acquisition unit 12 includes a calculation circuit that obtains the latitude and longitude of the current position by a GPS (Global Positioning System) function. By executing the GPS function, the position information acquisition unit 12 obtains time information received from each of a plurality of artificial satellites and latitude and longitude information of each artificial satellite via a GPS antenna (not shown). Based on the trajectory information included, the latitude and longitude of the current position are obtained from a predetermined arithmetic expression. When the position information acquisition unit 12 receives the control signal from the schedule management unit 151, the position information acquisition unit 12 acquires the position information at regular time intervals and notifies the movement prediction unit 154 of the acquired position information.

  The method for acquiring the position information is not limited to the method using the GPS function. The position information acquisition unit 12 is in a state in which the wireless communication unit 11 can communicate with a plurality of base stations, and when the latitude and longitude information of each base station is notified to the portable terminal 50, the wireless communication unit 11 The position information may be obtained based on the intensity of the radio wave received from the base station. In PHS, position information can be acquired by this method. As a specific example, the distance between each of the three base stations and its own device is predicted based on the strength of the radio wave received from each of the three base stations, and the three points are used to calculate the distance from the predicted three distances. It is possible to determine the position of the device. Further, when the user passes through the ticket gate of the station, the short-range communication unit 111 communicates with the ticket gate, so that the position information acquisition unit 12 displays the station information notified from the ticket gate by the short-range communication unit 111. It is good also considering the station where a user exists now as positional information.

  Further, the position information acquisition method is not limited to any one of the plurality of methods described above, and two or more methods may be combined. As an example of a combination of the two, AGPS (Assisted GPS) that combines a GPS function and the strength of radio waves from a plurality of base stations is known. In particular, in places where it is difficult to receive radio waves from artificial satellites, such as underpasses and valleys of buildings, methods other than GPS are effective for obtaining position information. In the following, a case will be described where the position information acquisition unit 12 acquires position information of the current position by executing the GPS function.

  Next, each component in the control unit 15 shown in FIG. 4 will be described.

  When the user operates the operation unit 16 to input a destination, a meeting date / time, and a message exchange time, the schedule management unit 151 stores the waiting information including these pieces of information in the storage unit 13. When a request for waiting information is received from the e-mail control unit 153, the waiting information is passed to the e-mail control unit 153. After that, when the waiting information to which the e-mail address information is added is received, it is already stored in the storage unit 13. The waiting information is updated to the contents added with the e-mail address. The schedule management unit 151 monitors the time measured by the clock unit 152, and when the remaining time until the meeting date and time is equal to or shorter than the message exchange time, in order to instruct the start of the message exchange process, the location information acquisition unit 12, e-mail A control signal is transmitted to the control unit 153 and the movement prediction unit 154.

  Note that the schedule management unit 151 may manage a schedule other than the waiting information, and perform management to notify the user by an alarm or the like when the date and time specified in the schedule comes. Further, when the user operates the operation unit 16 and inputs an instruction to transmit the waiting information via the short-range communication unit 111, the schedule management unit 151 sends the waiting information to the outside via the short-range communication unit 111. Send to.

  The clock unit 152 measures the time according to the clock signal in the own device. When an error occurs between the time to be measured and the correct time, the clock unit 152 receives the correct time from the base station when the wireless communication unit 112 communicates with the base station. The time error may be corrected based on the time information received by the unit 112 from the base station.

  The configuration of the movement prediction unit 154 will be described. FIG. 6 is a flowchart showing the operation of the movement prediction unit 154. The movement prediction unit 154 includes a temporary storage memory (not shown), and temporarily stores a change over time in acceleration measured by the acceleration sensor 17 when receiving a control signal to start message exchange processing from the schedule management unit 151. Accumulate in memory (step 201). When the movement prediction unit 154 acquires the position information from the position information acquisition unit 12, the movement prediction unit 154 calculates a distance d between the destination and the position information (step 202). As an example of the calculation method of the distance d, there is a method of calculating using the three-square theorem from the latitude and longitude coordinates in each of the destination and the position information. It is determined whether or not the distance d calculated in step 202 is equal to or smaller than a predetermined distance. If the distance d is equal to or smaller than the predetermined distance, the movement prediction unit 154 ends the process, and the distance d is smaller than the predetermined distance. If so, go to step 204. In the case of the table shown in FIG. 5, the predetermined distance serving as a determination criterion is 30 m.

  Further, the movement prediction unit 154 calculates the average speed of the portable terminal 50 based on the information on the change with time of the acceleration accumulated in the temporary storage memory. This average speed corresponds to the moving speed v of the table shown in FIG. 5 (step 204). Subsequently, the movement prediction unit 154 refers to the table stored in the storage unit 13 and selects a message corresponding to the calculated distance d and movement speed v (step 205). Thereafter, the movement prediction unit 154 passes the selected message to the e-mail control unit 153 (step 206), erases the information in the temporary storage memory, and returns to step 201. In the table stored in the storage unit 13, when a numerical value is not written in the movement speed, the movement prediction unit 154 selects a message according to the distance d without depending on the magnitude of the movement speed.

  When the user operates the operation unit 16 to select waiting information and designates an e-mail address as a destination, the e-mail control unit 153 creates an e-mail attached with the waiting information and sends the e-mail via the wireless communication unit 112. send mail. Then, the e-mail control unit 153 includes information on the address that is the destination of the transmitted e-mail in the waiting information and returns it to the schedule management unit 151.

  Further, when the e-mail control unit 153 receives a control signal for starting the message exchange process from the schedule management unit 151 and then receives the e-mail via the wireless communication unit 112, the source of the received e-mail is changed. It is determined whether or not it matches the e-mail address of the waiting information. As a result of the determination, if these e-mails match, the e-mail control unit 153 displays a message attached to the e-mail on the display unit 14, and if these e-mails do not match, the e-mail has been received. Is displayed on the display unit 14. Further, upon receiving a message from the movement prediction unit 154, the e-mail control unit 153 creates an e-mail including the message, and transmits the e-mail to the e-mail address included in the waiting information.

  Here, when a plurality of pieces of waiting information are stored in the storage unit 13, the e-mail address read by the e-mail control unit 153 is described in the waiting information whose time until the waiting time is equal to or less than the message exchange time. Addresses. The schedule management unit 151 includes the waiting information to be subject to message exchange processing in the control signal transmitted to the email control unit 153, so that the email control unit 153 identifies the waiting information to be subject to message exchange processing. You may be able to do it.

  In addition, in this embodiment, although the control method in case a user's moving means is either walking or other than that is demonstrated, when the moving means is decided beforehand as one like "walking only", There is no need to provide the acceleration sensor 17, a table describing a message according to the distance d is prepared, and the movement prediction unit 154 may select the message according to the distance d.

  Next, the operation of the mobile terminal of this embodiment will be described. FIG. 7 is a diagram illustrating an example of a communication system including the mobile terminal according to the present embodiment.

  Each of the portable terminals 50a and 50b illustrated in FIG. 7 corresponds to the portable terminal 50 described with reference to FIG. As shown in FIG. 7, portable terminals 50 a and 50 b and server 40 are connected to network 30. The server 40 uses latitude and longitude as coordinates, a storage unit 41 for storing map information in which main place names and building names are described, and control for providing map information in response to requests from the mobile terminals 50a and 50b. Part 42. The range of the map which the memory | storage part 41 memorize | stores is wider than the map stored in portable terminal 50a, 50b. The control unit 42 refers to the map stored in the storage unit 41 and converts names such as a place name and a building name into coordinate information of latitude and longitude of the position indicated by the name.

  FIG. 8 is a sequence diagram showing the operation of the communication system shown in FIG. FIG. 9 is a flowchart showing an operation procedure of the mobile terminal according to the present embodiment. FIG. 9 is a flowchart in the case where the mobile terminal 50a is the main body, but the same applies to the mobile terminal 50b.

  The user A of the portable terminal 50a talks with the user B of the portable terminal 50b directly or by telephone, and determines the meeting place and the meeting date and time. The user A operates the operation unit 16 of the portable terminal 50a and inputs the waiting information in which the meeting place, the meeting date and time, and the message exchange time are set. After storing the waiting information in the storage unit 13 (step 1201), the portable terminal 50a reads the name of the meeting place from the waiting information and sends a request for the coordinate information and a coordinate information request signal including information on the name to the network 30. To the server 40 (step 1202).

  When receiving the coordinate information request signal from the portable terminal 50a, the control unit 42 of the server 40 reads the name information from the coordinate information request signal, refers to the map information stored in the storage unit 41, and indicates the position indicated by the read name. The coordinate information of the latitude and longitude is read out (step 1203). And the control part 42 transmits the positional information containing the information of the latitude and the longitude to the portable terminal 50a (step 1204). When receiving the position information from the server 40, the portable terminal 50a rewrites the meeting place in the meeting information with the position information. Thereafter, when the user A operates the portable terminal 50a to input an instruction to transmit the waiting information to the portable terminal 50b, the portable terminal 50a transmits the waiting information to the portable terminal 50b (step 1205).

  Here, the case where the user A and the user B meet will be described, but the number of people waiting is not limited to two, and may be three or more. The meeting information may be transmitted from the portable terminal 50 a to the portable terminal 50 b using the short-range communication unit 111, and an e-mail attached with the meeting information is transmitted via the network 30 using the wireless communication unit 112. You may send it.

  An example in which the number of people waiting is two or more and the short-range communication unit 111 notifies the waiting information will be described. At a regular meeting, the secretary decides the schedule for the next meeting at the end of the meeting held on one day, and the secretary creates the schedule for the next meeting by operating his mobile device. In a place where everyone is present, it is conceivable to use the short-range communication unit 111 to directly transmit the schedule from the secretary's mobile terminal to the mobile terminals of other participants.

  An example in which waiting information is notified by e-mail via the network 30 will be described. After multiple members decide the date and time of the meeting by telephone or other means of contact, the secretary operates the mobile terminal to register the waiting information in the mobile terminal, and attaches the waiting information to an e-mail and carries the other member's mobile phone. Send to the terminal. The mobile terminal that has received the e-mail stores the waiting information attached to the e-mail in the storage unit.

  Also, an e-mail format for notifying waiting information may be determined in advance. As described above, after multiple members decide the date and time of the meeting by means of telephone or other communication means, the secretary operates the mobile terminal and registers the location information and the waiting time in the e-mail format. While being stored as a schedule, an e-mail is transmitted to the mobile terminals of other members. The mobile terminal that has received the e-mail reads position information, waiting information, and the like from the e-mail, and stores the read information in the storage unit as waiting information.

  In step 1205 of FIG. 8, the mobile terminal 50a shows a case where the waiting information is attached to the electronic mail and transmitted to the mobile terminal 50b. The portable terminal 50b stores the waiting information received from the portable terminal 50a in the storage unit 13 (step 1206).

  Thereafter, when the time until the meeting time becomes equal to or shorter than the message exchange time, the portable terminal 50a calculates the distance d and the moving speed v between the current position and the destination according to the determination in step 1101 shown in FIG. A message corresponding to the moving speed v is selected from the table (steps 1102, 1103, 1105). Then, the portable terminal 50a transmits an electronic mail including the selected message to the portable terminal 50b (Step 1207 shown in FIG. 8 and Step 1106 shown in FIG. 9). Similarly to the portable terminal 50a, the portable terminal 50b creates an electronic mail and transmits it to the portable terminal 50a (step 1209 shown in FIG. 8, steps 1102, 1103, 1105, and 1106 shown in FIG. 9).

  When receiving the electronic mail (step 1007 in FIG. 9), the portable terminal 50b determines whether or not the transmission source of the electronic mail is the portable terminal 50a (step 1008 in FIG. 9), and the transmission source of the received electronic mail If the mobile terminal 50a is, the message attached to the e-mail is displayed on the display unit 14 (step 1009 in FIG. 9 and step 1208 in FIG. 8). On the other hand, when the transmission source of the received electronic mail is not the mobile terminal 50a, the mobile terminal 50b displays on the display unit 14 that the electronic mail has been received (step 1010). Similarly to the portable terminal 50a, the portable terminal 50a determines whether or not to display the message attached to the e-mail (step 1210 shown in FIG. 8 and steps 1007 to 1010 shown in FIG. 9). Until the distance d to the meeting place becomes equal to or less than a predetermined distance, the portable terminals 50a and 50b transmit an electronic mail including a message to the partner portable terminal (step 1104 shown in FIG. 9).

  FIG. 10 is a diagram illustrating an example of the screen of the display unit. FIG. 10A shows an example of the screen of the display unit 14 of the mobile terminal 50a, and FIG. 10B shows an example of the screen of the display unit 14 of the mobile terminal 50b. As shown in FIG. 10A, the display unit 14 of the portable terminal 50a displays that the user B arrives at the destination in “a few minutes”. As shown in FIG. 10B, the display unit 14 of the portable terminal 50b displays that the user A has arrived at the destination. In addition, the screen in FIG. 10B displays that an e-mail has been received from a terminal other than the portable terminal 50a.

  In this way, for each of the user A and the user B, a message corresponding to the time taken from the current location to the meeting place is notified to the portable terminal of another user at a constant time interval and displayed on the display unit. As a result, the user A and the user B do not need to perform an operation for notifying other users of the estimated arrival time while moving to the meeting place.

  In addition, e-mail received from a terminal other than the person who is waiting is treated as a normal mail, but for an e-mail received from the terminal of the person who is waiting, a message attached to the e-mail is displayed on the display unit. Is displayed. Therefore, the user A and the user B quickly select an e-mail to be opened, and how long the other members will arrive at the meeting place without performing the operation of opening the selected e-mail. It becomes possible to know.

  According to the present embodiment, when approaching the date and time of waiting for each member, the waiting time is a guideline for how long it will arrive at the meeting place without operating the mobile terminal by itself. Can be transmitted to the mobile terminals of other members. In addition, since an e-mail message received from the mobile terminal of another member is displayed on the display unit, it is not necessary to open the e-mail by operating the mobile terminal by yourself. Therefore, it is possible to check on the screen of the display section how long other members can go to the meeting place without operating the mobile terminal by themselves. As a result, the load on the operation of the user's mobile terminal is reduced.

  In addition, even when there is a member who is late in the meeting place, the member who arrives first can grasp how long the member who arrives late arrives, and the stress generated when waiting is reduced. Furthermore, while moving to the meeting place, it is possible to check the movement state of each other by exchanging messages with other members many times. According to the present embodiment, it is possible to provide the user with a user interface that can reduce the load related to the operation.

  In the present embodiment, the case where the position information acquisition unit 12 obtains the position information of the mobile terminal 50 from the radio wave received from the GPS or the radio wave received from the base station has been described. However, the calculation process executed by the position information acquisition unit 12 May be executed by a CPU (not shown) provided in the control unit 15. Further, in the present embodiment, the case where the user inputs the message exchange time has been described, but it may be set in the waiting information in advance.

  Further, in the portable terminal of the present embodiment, after the time until the meeting date and time is equal to or less than the message exchange time, it is determined whether or not to open the received e-mail. As explained in the case of performing registration depending on whether or not it is registered in the e-mail, the sending terminal attaches to the e-mail unique header information for instructing opening of the e-mail, and the receiving terminal sends a header to the e-mail. Whether or not to display an e-mail message on the display unit 14 may be determined based on whether or not information is attached.

(Second Embodiment)
In this embodiment, in the first embodiment, a character that is different for each member that is waiting is displayed on the display unit together with a message from another member that is waiting. In the present embodiment, a configuration different from that of the first embodiment will be described in detail, and a detailed description of the same configuration and operation as those of the first embodiment will be omitted.

  The configuration of the mobile terminal of this embodiment will be described with reference to FIG.

  In the storage unit 13, images of a plurality of types of characters are registered in advance. When the waiting information including a plurality of e-mail addresses is stored in the storage unit 13, the user of the portable terminal 50a operates the operation unit 16 to select a plurality of types of characters for each of the plurality of e-mail addresses. A different character is designated for each e-mail address and registered in the waiting information.

  When the e-mail control unit 153 displays an e-mail message with the address registered in the waiting information as a transmission source on the display unit 14, the e-mail control unit 153 displays the character registered with the address next to the message. .

  In the present embodiment, the operation is the same as that of the mobile terminal of the first embodiment except that the mobile terminal displays the character together with the message on the display unit, and thus detailed description of the operation is omitted. The screen of the display unit will be described in detail.

  FIG. 11 is a diagram illustrating an example of a screen of the display unit of the mobile terminal according to the present embodiment. Here, in addition to user A of mobile terminal 50a and user B of mobile terminal 50b described in the first embodiment, user C of mobile terminal 50c is added as a waiting member.

  11A shows an example of the screen of the display unit 14 of the mobile terminal 50a, FIG. 11B shows an example of the screen of the display unit 14 of the mobile terminal 50b, and FIG. 11C shows the screen of the mobile terminal 50c. An example of the screen of the display part 14 is shown.

  As shown in FIG. 11 (a), a message that “arriving in a few minutes” is displayed next to the character 71 corresponding to the user B on the display unit 14 of the portable terminal 50a. A message indicating that “10 minutes or more” is required is displayed next to the corresponding character 72. On the display unit 14 of the mobile terminal 50b shown in FIG. 11B, a message indicating that the destination has been reached is displayed next to the character 73 corresponding to the user A, and next to the character 72 corresponding to the user C. A message indicating that “10 minutes or more” is required is displayed. In addition, the screen in FIG. 11B displays that an e-mail has been received from a terminal other than the mobile terminals 50a and 50c. On the display unit 14 of the portable terminal 50c shown in FIG. 11C, a message that “arriving in a few minutes” is displayed next to the character 71 corresponding to the user B, corresponding to the user A. Next to the character 73, a message indicating that it has arrived at the destination is displayed.

  According to the present embodiment, not only the same effect as in the first embodiment can be obtained, but also characters corresponding to the members are displayed in each message even if the number of members waiting is three or more. Because it is displayed in the department, it becomes easier to see who will arrive at the meeting place. In the present embodiment, the case where a character is displayed together with a message has been described. However, information other than the character may be used as long as it is information for identifying the person such as the name of the person who is waiting.

(Third embodiment)
In the present embodiment, the frequency of message exchange is increased when approaching the meeting place in the first embodiment. Since this embodiment has the same configuration as that of the first embodiment, operations different from those of the first embodiment will be described in detail.

  FIG. 12 is a flowchart showing a part of the operation of the mobile terminal of this embodiment. FIG. 12 shows a part to be added to the flowchart shown in FIG. The second distance in step 1104 in FIG. 12 corresponds to the “predetermined distance” shown in step 1104 in FIG. 9, and the first distance is larger than the second distance.

  The movement prediction unit 154 determines whether or not the calculated distance d is equal to or less than the first distance (step 1301), and if the distance d is equal to or less than the first distance, the position information acquisition unit 12 stores the position information. While increasing the acquisition frequency, the calculation frequency of the moving speed v is increased. As a result, the electronic mail control unit 153 increases the number of messages notified from the movement prediction unit 154 per unit time, and thus increases the transmission frequency of the electronic mail (step 1302). If the distance d is greater than the first distance in step 1301, the movement prediction unit 154 proceeds to step 1104.

  In the flowchart shown in FIG. 12, the processing of step 1302 may be performed a plurality of times by a loop. However, if the processing of step 1302 is performed once, the processing of step 1302 is performed even if the processing proceeds to the second time. The program may be written so as not to be executed, or the program may be written so as to increase the transmission frequency of the e-mail step by step each time the processing of step 1302 is performed according to a loop.

  In this embodiment, not only the same effect as in the first embodiment is obtained, but if the frequency of message exchange increases as the distance to the meeting place approaches, the person who arrives at the meeting place earlier will be delayed. Since it is possible to frequently receive notifications of arrival schedules of visitors, the stress caused by waiting is reduced. This embodiment may be applied to the second embodiment.

  The present invention is a mobile terminal device such as a mobile phone, PHS, PDA (Personal Digital Assistants), and has a communication function such as e-mail and a position information acquisition function such as GPS. Can be applied to.
