  Hereinafter, the reception system 100 will be described in detail with reference to FIGS.

  FIG. 1 schematically shows a configuration of a reception system 100 according to an embodiment. The reception system 100 according to the present embodiment is a system that is used in reception at a hospital, reception at a pharmacy, or the like, and is a system for making a call to a mobile terminal of a person who is waiting in turn at reception at an appropriate timing. .

  As illustrated in FIG. 1, the reception system 100 includes a mobile terminal 10 and a server 50. The mobile terminal 10 can communicate with a base station 70 connected to a network 80 including a carrier communication network and the Internet. The server 50 is connected to the network 80.

  The mobile terminal 10 is a terminal such as a mobile phone or a smartphone held by a person (referred to as a user) who is waiting for a turn in reception at a hospital or a pharmacy. The mobile terminal 10 has a function of detecting the user's movement route by autonomous navigation, a function of cooperating with the server 50 when the user is waiting in turn at the reception, in addition to the call function and the Internet function.

  FIG. 2A shows a hardware configuration of the mobile terminal 10. As shown in FIG. 2A, the mobile terminal 10 includes a display unit 11, an input unit 13, an acceleration sensor 15, a geomagnetic sensor 17, a gyro sensor 19, a GPS (Global Positioning System) module 21, a communication unit 23, and a control. The apparatus 20 etc. are provided.

  The display unit 11 includes a liquid crystal display, an organic EL (Electro-Luminescence) display, and the like, and displays various types of information under instructions from the control device 20. The input unit 13 includes a touch panel and a keyboard, and is used by the user to input various information.

  The acceleration sensor 15 is a sensor that can detect the acceleration in the triaxial direction that acts on the mobile terminal 10. The geomagnetic sensor 17 is a sensor capable of detecting geomagnetism on a three-axis coordinate system. The gyro sensor 19 is a sensor that can detect angular velocities in three axial directions. The GPS module 21 receives GPS data from GPS satellites, and acquires position information of the mobile terminal 10, here latitude and longitude.

  The communication unit 23 performs communication with the server 50 via the base station 70 and the network 80 illustrated in FIG.

  The control device 20 comprehensively controls the operation of each unit of the mobile terminal 10. FIG. 2B shows the hardware configuration of the control device 20. As shown in FIG. 2B, the control device 20 includes a CPU (Central Processing Unit) 90, a ROM (Read Only Memory) 92, a RAM (Random Access Memory) 94, and a storage unit (here, an HDD (Hard Disk Drive)). 96), an input / output interface 97, and the like. Each part of the control device 20 is connected to the bus 98. The input / output interface 97 is connected to each unit, each sensor, and the like shown in FIG. In the control device 20, when the CPU 90 executes a program (including a movement information processing program) stored in the ROM 92 or the HDD 96, a movement trajectory information acquisition unit 30 as an acquisition unit and an extraction unit as shown in FIG. The functions of the movement trajectory processing unit 32 as the information transmission unit 34, the information transmission unit 34 as the calculation unit, and the notification unit 36 are realized. 3 also shows a movement locus line management table 40, a duplication management table 42, and a movement locus line management table (after correction) 44 stored in the HDD 96 or the like.

  The movement trajectory information acquisition unit 30 acquires detection results of the acceleration sensor 15, the geomagnetic sensor 17, the gyro sensor 19, and the GPS module 21. Then, the movement trajectory information acquisition unit 30 calculates the positioning coordinates of the user by autonomous navigation and stores them in the movement trajectory line management table 40. Further, the movement trajectory information acquisition unit 30 calculates the user's movement distance, movement speed, and movement trajectory line function based on the user's positioning coordinates, and stores them in the movement trajectory line management table 40. Here, the autonomous navigation is a GPS module that estimates the user's position coordinates using the detection results of the acceleration sensor 15 and the geomagnetic sensor 17 or the gyro sensor 19 and intermittently obtains the user's position coordinates. This is a method of calculating the positioning coordinates of the user by correcting using the detection results of 21. By using this autonomous navigation, the number of times of detection by the GPS module 21 can be suppressed, and there is an advantage that power consumption can be reduced.

  FIG. 5 shows the data structure of the movement trajectory line management table 40. As shown in FIG. 5, the movement trajectory line management table 40 includes “sample ID”, “positioning coordinate”, “positioning time”, “positioning interval”, “movement distance”, “movement speed”, “movement trajectory line function”. ”Field.

  In the “sample ID” field, the serial number of the positioning coordinates of the user calculated by the movement trajectory information acquisition unit 30 is stored. In the “positioning coordinate” field, the user's positioning coordinates (latitude and longitude) calculated by the movement trajectory information acquisition unit 30 are stored. The “positioning time” field stores the time at which the user's positioning coordinates are calculated. The “positioning interval” field stores an interval at which the user's positioning coordinates are calculated. The “movement distance” field stores a distance value calculated from the positioning coordinates acquired immediately before and the positioning coordinates acquired next. It should be noted that the movement distance calculated from the information on the number of steps obtained from the acceleration sensor 15 and the information on the user's predetermined step length may be stored in the “movement distance” field. The “moving speed” field stores the value of the moving speed of the user calculated based on the moving distance and the positioning interval. The field of “movement trajectory line function” stores an expression of a linear function indicating the direction in which the user is moving on the relative coordinate system (XY coordinate system). The relative coordinate system is assumed to be associated in advance with an absolute coordinate system represented by latitude and longitude.

  The movement trajectory processing unit 32 is based on the information on the route (outward route) from which the user has moved from the reception while the user is waiting for the turn at the reception, and the route that the user is likely to move when returning to the reception ( Information on the return trip) is calculated. Specifically, the movement trajectory processing unit 32 uses the duplication management table 42 to connect the reception along the forward movement trajectory as shown by a broken line in FIG. A redundant trajectory other than the trajectory is extracted, and this redundant trajectory is deleted from the forward movement trajectory to obtain a return path as shown in FIG. In addition, the movement trajectory processing unit 32 stores information on the calculated return path in the movement trajectory line management table (after correction) 44.

  FIG. 6B shows an example of the data structure of the movement trajectory line management table (after correction) 44. The movement trajectory line management table (after correction) 44 has fields of “sample ID”, “positioning coordinates”, “positioning time”, “movement distance”, and “movement speed” as shown in FIG. 6B. . As can be seen by comparing the movement trajectory line management table (after correction) 44 in FIG. 6B and the movement trajectory line management table 40 in FIG. 5, the movement trajectory line management table (after correction) 44 is “positioning interval”. ”And“ movement trajectory line function ”are not provided. Further, in the movement track line management table (after correction) 44, data of sample ID = 4 to (N−1) existing in the movement track line management table 40 is deleted.

  The duplication management table 42 has a data structure as shown in FIG. 6A, details of which will be described later.

  The information transmission unit 34 transmits to the information reception unit 52 of the server 50 the sum of the movement distances of the return path calculated from the data stored in the movement track line management table (after correction) 44 and the average movement speed. .

  When there is a call from the server 50, the notification unit 36 notifies the user that the call has been received from the reception using the display unit 11, a speaker (not shown), a vibrator, or the like.

  Returning to FIG. 1, the server 50 is a device that executes processing in hospital reception. FIG. 4 shows the hardware configuration of the server 50. As shown in FIG. 4, the server 50 includes a CPU 190, a ROM 192, a RAM 194, a storage unit (HDD) 196, a network interface 197, a display unit 193, an input unit 195, a portable storage medium drive 199, and the like. Each part of the server 50 is connected to the bus 198. The display unit 193 includes a liquid crystal display and the like, and the input unit 195 includes a keyboard and a mouse. In the server 50, when the CPU 190 executes a program stored in the ROM 192 or the HDD 196 or a program read by the portable storage medium drive 199 from the portable storage medium 191, the information receiving unit 52 shown in FIG. The function of the call processing unit 54 as a time calculating unit and a calling unit is realized. FIG. 3 also shows a call management table 60 stored in the HDD 196 or the like.

  The information receiving unit 52 receives the information transmitted from the mobile terminal 10 side (average of moving distance and moving speed on the return path) and stores the information in the call management table 60. The call management table 60 is a table for managing the time until the user is called at the reception. FIG. 7 shows an example of the data structure of the call management table 60. As shown in FIG. 7, the call management table 60 includes “order ID”, “user ID”, “total moving distance”, “average moving speed”, “moving time”, “time until start of reception”, “ It has a field of “Remaining time until call”. The “order ID” field stores a serial number assigned to the user in the order of acceptance. The user identifier is stored in the “user ID” field. The “total distance traveled” field stores the total distance traveled on the return path transmitted from the mobile terminal 10 side. The “average moving speed” stores the average moving speed transmitted from the mobile terminal 10 side. The “travel time” stores the time required to travel on the return path calculated from the value stored in the “total travel distance” field and the value stored in the “average travel speed” field. “Time to start reception” stores the time until the user needs to arrive at the reception. In the present embodiment, it is assumed that reception is performed at intervals of 30 seconds in the order of the order ID. In the “remaining time until call” field, a time until a call is executed for a user waiting for reception, that is, a time obtained by subtracting the travel time from the time until reception starts is stored. . It should be noted that the fields of “sum of moving distance”, “average moving speed”, “moving time”, and “remaining time until calling” in the call management table 60 are the movement track line management table (after correction) 44 in the mobile terminal 10. It is updated every time is updated.

  The call processing unit 54 updates the “time until reception start” and “remaining time until call” fields in the call management table 60, or executes a call to the mobile terminal 10 based on the call management table 60. . Note that the call processing unit 54 calls the user's mobile terminal 10 whose value of “remaining time until call” in the call management table 60 is 0 (sec) or less.

  Next, the processing of the reception system 100 will be described in detail along the flowcharts of FIGS.

(Update processing of the call management table 60 by the server 50)
FIG. 8 shows update processing of the call management table 60 by the server 50. This process is a process executed by the call processing unit 54 of the server 50. 8 is a process that is started when the server 50 is turned on and the hospital reception process is started.

  In the process of FIG. 8, first, in step S10, the call processing unit 54 determines whether or not there is a stop request. This stop request is a request that the staff member in charge of reception at the hospital inputs via the input unit 195 at the end of the day, for example. If the determination in step S10 is affirmed, the entire process of FIG. 8 is terminated. If the determination is negative, the process proceeds to step S12.

  In step S12, the call processing unit 54 determines whether a predetermined time has elapsed. The predetermined time is assumed to be 30 seconds, for example. Note that the timing at which the determination at step S12 is affirmed is preferably the same timing as the timing at which the determination at step S31 in FIG. 11 described later is affirmed, that is, the timing at which information is received from the mobile terminal 10. If the determination in step S12 is negative, the process proceeds to step S16. If the determination is positive, the process proceeds to step S14.

  When the process proceeds to step S14, the call processing unit 54 updates the time until the start of reception. Specifically, the call processing unit 54 subtracts 30 (sec) from each value stored in the “time until reception start” field of the call management table 60. Thereafter, the process proceeds to step S16.

  If transfering it to step S16, the call process part 54 will judge whether the user ID of the user waiting for reception was newly input. The staff in charge of reception at the hospital inputs the user ID via the input unit 195 when a new user visits the hospital. In addition, when a staff member in charge of reception at the hospital inputs a user ID, the server 50 recognizes the user's portable terminal 10 to associate the user ID and the portable terminal 10 with the call processing unit 54. Like that. If the determination in step S16 is negative, the process returns to step S10. If the determination is positive, the process proceeds to step S18.

  In step S 18, the call processing unit 54 issues a new order ID and adds a user ID to the call management table 60. Thereafter, the process returns to step S10.

  After returning to step S10, the above-described processing and determination are repeated, and when the determination in step S10 is affirmed, that is, when there is a stop request, all the processing in FIG.

(Processing of the mobile terminal 10)
Next, processing by the mobile terminal 10 held by the user waiting for the turn will be described with reference to the flowcharts of FIGS.

  9 and 10 are processes executed from the stage where the user ID and the mobile terminal 10 are associated with each other in the call processing unit 54 as described above.

  In the process of FIG. 9, first, in step S100, the movement trajectory information acquisition unit 30 always starts positioning. The constant positioning in this case means a calculation process of the positioning coordinates of the user using autonomous navigation, which is executed every 30 seconds in the movement trajectory information acquisition unit 30.

  Next, in step S102, the movement trajectory information acquisition unit 30 determines whether or not there is a stop request. The user inputs a stop request via the input unit 13 when a call from the server 50 becomes unnecessary. When the determination in step S102 is affirmed, the process proceeds to step S150, and the movement trajectory information acquisition unit 30 ends the all processes in FIG. On the other hand, if the determination in step S102 is negative, that is, if there is no stop request, the process proceeds to step S104.

  In step S104, the movement trajectory information acquisition unit 30 creates a new sample ID record (sample) in the movement trajectory line management table 40, and stores the positioning time and the positioning coordinates. Next, in step S106, the movement trajectory information acquisition unit 30 calculates a positioning interval from the current positioning time and the previous positioning time, and stores it as a sample of a new sample ID in the movement trajectory line management table 40.

  Next, in step S108, the movement trajectory information acquisition unit 30 calculates the movement distance from the current and previous position coordinates and stores it as a sample of a new sample ID in the movement trajectory line management table 40. Next, in step S110, the movement trajectory information acquisition unit 30 obtains a function of the movement trajectory line between the current and previous positioning times from the current and previous position coordinates, and stores the movement trajectory line management table 40. Store as a new sample ID sample. The function of the movement trajectory line is a function that represents a straight line that passes through the position coordinates immediately before this time on the relative coordinate system (XY coordinate system).

  In addition, the data storage to the sample of new sample ID of the movement trace line management table 40 is completed by performing step S104-S110. In the following, for the convenience of explanation, the processing of steps S112 to S122 will be described on the assumption that data of sample ID = 1 to N is stored in the movement trajectory line management table 40.

  If transfering it to step S112, the movement locus | trajectory process part 32 will specify the sample with the smallest sample ID among the unevaluated samples in each sample (sample ID = 1-N) of the movement locus | trajectory line management table 40. FIG. An unevaluated sample is a sample that has not been specified yet after the processing of steps S104 to S112 is completed. Therefore, when step S112 is executed first after step S110, the sample with sample ID = 1 is identified as the sample with the smallest sample ID among the unevaluated samples.

  Next, in step S114, the movement trajectory processing unit 32 determines whether there is a sample having a movement trajectory line function similar to the movement trajectory line function of the identified sample in the sample having the sample ID larger than the identified sample. To do. That is, it is determined whether or not a movement locus line function similar to the movement locus line function of sample ID = 1 exists in sample ID = 2 to N. Note that the movement trajectory line functions are similar when, for example, the difference between the inclinations of the movement trajectory line functions is within a range of ± 2.0 and the difference between intercept values is within a range of ± 2.0. means. If the determination in step S114 is negative, the process proceeds to step S122.

  When the process proceeds to step S122, the movement trajectory processing unit 32 determines whether all unevaluated samples have been specified. Here, since only the sample with sample ID = 1 has been specified, the determination is denied and the process returns to step S112.

  Returning to step S112, the movement trajectory processing unit 32 identifies the sample with the sample ID = 2, and proceeds to step S114. In step S114, as described above, it is determined whether or not there is a sample having a movement trajectory line function similar to the movement trajectory line function of the identified sample in the sample having the sample ID larger than the identified sample. For example, it is assumed that the movement trajectory line function of sample ID = 2 is similar to the movement trajectory line function of the sample of sample ID = (N−2). In this case, the determination in step S114 is affirmed, and the process proceeds to step S116.

  In step S116, the movement trajectory processing unit 32 determines whether or not the corresponding sample, that is, the sample having a similar movement trajectory line function, is continuous with the identified sample. If the determination in step S116 is affirmative, the process proceeds to step S122. If the determination in step S116 is negative, the process proceeds to step S118. If the movement trajectory line function of sample ID = 2 is similar to the movement trajectory line function of sample ID = (N−2), sample ID = 2 and (N−2) are shown in FIG. Since it is not continuous as shown, determination of step S116 is denied and the movement locus | trajectory process part 32 transfers to step S118.

  In step S118, the movement trajectory processing unit 32 determines whether or not the distance between the positioning coordinates of the corresponding sample is within a predetermined distance. That is, the movement trajectory processing unit 32 determines whether or not the positioning coordinates of the corresponding sample are included in a predetermined range associated with the specified positioning coordinates of the sample. Here, the predetermined distance is, for example, a distance of about 1 / p (p is, for example, 5 or 10) of the value stored in the “movement distance” field of the corresponding sample. The predetermined distance may not be a distance based on the moving distance. For example, the predetermined distance may be a distance based on a positioning error or GPS error in autonomous navigation, or may be a predetermined fixed value. If the determination in step S118 is negative, the process proceeds to step S122. If the determination is positive, the process proceeds to step S120.

  Note that the case where the process proceeds to step S120 is a case where the user moves in the same direction at the same position at a different time, that is, the case where the movement route loops as shown in FIG. means.

  In step S120, the movement trajectory processing unit 32 stores each sample ID in the duplication management table 42. Here, the duplication management table 42 has a data structure as shown in FIG. In the duplication management table 42, sample IDs of two similar samples obtained in steps S112 to S118 are stored in association with the duplication ID. In FIG. 6A, the above-described sample ID = 2 is stored in the “sample ID1” field with the duplicate ID = 1, and the sample ID = (N−2) is stored in the “sample ID2” field with the duplicate ID = 1. Stored. After the process of step S120 is complete | finished, it transfers to step S122.

  Thereafter, the processes and determinations in steps S112 to S122 are repeated until the determination in step S122 is affirmed, that is, until the processes in steps S114 to S120 for all the samples in the movement trajectory line management table 40 are completed. Then, when the determination in step S122 is affirmed, the movement trajectory processing unit 32 proceeds to step S130 in FIG. In the present embodiment, it is assumed that the duplication management table 42 is transferred to step S130 in a state where data with duplication ID = 1, 2 is stored as shown in FIG.

  In step S130, the movement trajectory processing unit 32 determines whether or not the sample ID is stored in the duplication management table 42. If the determination in step S130 is negative, that is, if no sample ID is stored in the duplication management table 42, the process returns to step S102. On the other hand, when the sample ID is stored in the duplication management table 42 as shown in FIG. 6A, the determination in step S130 is affirmed, and the movement locus processing unit 32 proceeds to step S132.

  When the process proceeds to step S132, the movement trajectory processing unit 32 refers to the sample IDs of all duplicate IDs and extracts a continuous portion. In the case of FIG. 6A, since ID = 2 and 3 of sample ID1 and ID = (N-2) and (N-1) of sample ID2 are continuous, the relevant part is extracted.

  Next, in step S134, the movement trajectory processing unit 32 adds all of the sample IDs obtained by adding 1 to the last sample ID1 of the continuous part and the sample IDs of the last sample ID2 of the continuous part. The sample is excluded and stored in the movement trajectory line management table (after correction) 44. In the case of FIG. 6A, the last sample ID1 of the continuous part is 3, and the sample ID of the last sample ID2 of the continuous part is (N-1). Therefore, the movement locus processing unit 32 excludes all data between the sample ID = 4 obtained by adding 1 to the sample ID = 3 and the sample ID = (N−1), and is illustrated in FIG. 6B. As described above, the data of sample IDs = 1 to 3 and N are stored in the movement trajectory line management table (after correction) 44. The information stored in the movement trajectory line management table (after correction) 44 is information on a route from which redundant trajectories as shown in FIG. 12B are excluded. That is, it can be said that the information stored in the movement trajectory line management table (after correction) 44 is information on a return path that is likely to move when the user returns to reception.

  In step S <b> 136, the information transmitting unit 34 obtains “total moving distance” and “average moving speed” based on the moving track line management table (after correction) 44, and transmits the information to the information receiving unit 52 of the server 50. To do. For example, in the case of FIG. 6B, the sum of the moving distance is 55 + 60 + 42 + 62 = 219 (m), and the average moving speed is (1.83 + 2.00 + 1.40 + 2.07) /4=1.825 (m / s). It becomes. In this case, the sum of the movement routes means the distance of the return path that is likely to move when the user returns to the reception, and the average movement speed is the average value of the movement speed expected when the user moves on the return path. Means.

  Next, in step S138, the notification unit 36 determines whether or not there is a call from the call processing unit 54 of the server 50. Details of the call by the call processing unit 54 of the server 50 will be described later. If the determination in step S138 is negative, the process returns to step S102. When returning to step S102, if there is no stop request (No at S102), the processing after step S104 is executed as described above. In the present embodiment, the processing after step S104 is repeated every 30 seconds. Further, when the processing from step S104 onward is repeated, all the data in the duplication management table 42 and the movement trajectory line management table (after correction) 44 are deleted.

  On the other hand, when there is a call from the server 50 and the determination in step S138 is affirmed, the process proceeds to step S140. When the process proceeds to step S140, the notification unit 36 notifies the user that there has been a call using the display unit 11, a speaker (not shown), a vibrator, or the like. For example, a message such as “Please return to reception” may be displayed on the display unit 11. In addition, a voice message similar to the message displayed on the display unit 11 may be output from the speaker, or a warning sound may be output. Thereafter, all the processes in FIGS. 9 and 10 are terminated.

  In FIG. 9 and FIG. 10, the movement trajectory information acquisition unit 30 acquires the information of the movement trajectory of the user's forward path from the reception that is the departure point to the current point by executing the processing of steps S104 to S110. It can be said that. In addition, it can be said that the movement trajectory processing unit 32 extracts redundant movement trajectory information from the information of the forward movement trajectory by executing the processes of steps S112 to S122. Further, it can be said that the movement trajectory processing unit 32 calculates the information of the movement trajectory on the return path by deleting the redundant trajectory from the information on the movement trajectory on the forward path by executing the processes of steps S132 to S136.

(Call processing by the server 50)
Next, the calling process executed in the server 50 will be described with reference to FIG. The process of FIG. 11 is a process executed in the server 50 in parallel with the process of FIG.

  In the process of FIG. 11, first, in step S30, the call processing unit 54 determines whether or not there is a stop request. The stop request in this case is the same request as the request in step S10 in FIG. If the determination in step S30 is affirmed, the entire process of FIG. 11 is terminated. If the determination is negative, the process proceeds to step S31.

  In step S31, the call processing unit 54 determines whether the information receiving unit 52 has received the total travel distance and the average travel speed from the mobile terminal 10. If the determination in step S31 is negative, the call processing unit 54 returns to step S30. On the other hand, if the determination in step S31 is affirmative, that is, if the information transmission unit 34 of the mobile terminal 10 executes the process in step S136 in FIG. 10, the determination in step S31 is affirmed, and the call processing unit 54 The process proceeds to S32.

  In step S32, the call processing unit 54 receives the total movement distance and average movement speed of each mobile terminal 10 from the information reception unit 52, and the “total movement distance” of the corresponding order ID in the call management table 60. Store in the field of “Average moving speed”. Note that the sum of the movement distances and the average movement speed transmitted from the mobile terminal 10 holding the movement locus line management table (after correction) 44 in FIG. 6B are the user ID of the call management table 60 in FIG. 0014 records are stored.

  Next, in step S34, the call processing unit 54 calculates the travel time from the total travel distance and the average travel speed, and subtracts the travel time from the time until the start of reception to calculate the “remaining time until the call”. Then, the call processing unit 54 stores the calculated result in the call management table 60. In the case of user ID = 0014 in FIG. 7, the movement time is 120 (sec) based on the total movement distance 219 (m) and the average movement speed 1.825 (m / s). The remaining time until the call is 0 (sec) obtained by subtracting the travel time (120 (sec)) from the time until the start of reception (120 (sec)).

  Next, in step S36, the call processing unit 54 determines whether the time until the call has become 0 (sec) or less. If the determination in step S36 is negative, the process returns to step S30. On the other hand, if the determination in step S36 is affirmative, the process proceeds to step S38, and the call processing unit 54 calls the notification unit 36 of the mobile terminal 10. In this case, the call processing unit 54 transmits an instruction for causing the notification unit 36 to execute a call operation (S140). The call is performed on the mobile terminal 10 associated with the user ID of the user whose time until the call is 0 (sec) or less. Further, the call processing unit 54 deletes the data of the user who made the call from the call management table 60. After step S38, the process returns to step S30, and thereafter, the above processing and determination are repeated until the determination in step S30 is affirmed.

  In the above description, the call processing unit 54 performs the call when the remaining time until the call is 0 (sec) or less. However, the present invention is not limited to this. For example, the call processing unit 54 returns to the reception after “xx minutes (seconds) has passed for each user's mobile terminal 10 based on the“ time remaining until call ”field of the call management table 60. Or the like may be transmitted every 30 seconds. Further, the call processing unit 54 may transmit a map screen showing a return path to the notification unit 36 of the mobile terminal 10 together with the message.

  As described above in detail, according to the present embodiment, the movement trajectory information acquisition unit 30 acquires information on the movement trajectory of the user's forward path from the reception that is the departure point to the current point, and the movement trajectory line management table. 40 (S104 to S110), the movement trajectory processing unit 32 extracts redundant movement trajectory information from the information of the forward movement trajectory (S112 to S122). Then, the movement trajectory processing unit 32 deletes the redundant trajectory from the information of the movement trajectory on the forward path, identifies the return path, and calculates the distance of the return path (S132 to S136). Here, when the user is called after moving from the reception to the current point, the user generally turns back. In addition, when the forward path includes a redundant path (such as a loop), the user is likely to select a path from which the redundant path is omitted as the return path. Therefore, as in this embodiment, the user can pass when returning to the reception by obtaining the distance of the return path from which the redundant trajectory such as the loop shown in FIG. It is possible to calculate the return path distance with high accuracy.

  In addition, according to the present embodiment, the call processing unit 54 is configured to return the user from the current position to the reception that is the departure point based on the information of the movement path of the return route that is likely to pass when the user returns to the reception. Calculate the time required for movement. Here, the information on the movement trajectory on the return path is, for example, the sum of the movement distances and the average movement speed. This makes it possible to calculate the time required to move on the return path in consideration of the movement path of the outward path on which the user has actually moved.

  In this embodiment, when the return path travel time is equal to or longer than the time until the start of reception, that is, when the value obtained by subtracting the return path travel time from the time until the start of reception is 0 (sec) or less. Make a call to the user. Thereby, a user can be called at an appropriate timing.

  Further, in the present embodiment, the movement trajectory processing unit 32 refers to the information on the movement trajectory of the forward path, and after the user passes a predetermined position at a certain time (first time), another time (second time) ), The movement trajectory between the two times when passing through the predetermined range associated with the predetermined position is defined as a redundant trajectory. Thereby, it is possible to specify a redundant locus such as a moving locus that loops as shown in FIG.

  In the above embodiment, when the mobile terminal 10 creates the movement trajectory line management table 40 or the movement trajectory line management table (after correction) 44 and transmits the total movement distance and the average movement speed on the return path to the server 50. Explained. However, the present invention is not limited to this. For example, the mobile terminal 10 may transmit to the server 50 the travel time of the return path determined from the total travel distance and the average travel speed on the return path. Further, the mobile terminal 10 may transmit the data of the movement trajectory line management table (after correction) 44 to the server 50 and cause the server 50 to execute the processes of steps S132 to S136 of FIG. Or it is good also as employ | adopting the modification demonstrated below.

(Modification)
Hereinafter, a modification is demonstrated in detail based on FIGS.

  FIG. 13 is a flowchart illustrating processing of the mobile terminal 10 according to the modification. In addition, in this modification, the movement locus | trajectory process part 32 and each table 40-44 of FIG.

  In the process of FIG. 13, in place of the processes of steps S104 to S136 in the processes of FIGS. 9 and 10, the process of step S200 indicated by a thick line frame is executed. In step S200, the information transmitting unit 34 of the mobile terminal 10 transmits the user's positioning coordinates and positioning time to the information receiving unit 52 of the server 50 every 30 seconds.

  14 and 15 are flowcharts showing the calling process of the server 50 according to the modification. In this modification, it is assumed that the call processing unit 54 of the server 50 has a function equivalent to that of the movement locus processing unit 32. Further, the server 50 is assumed to include the movement trajectory line management table 40, the duplication management table 42, and the movement trajectory line management table (after correction) 44 that the mobile terminal 10 of the above-described embodiment has.

  14 and 15 are processes executed in parallel with the process of FIG. 14 and FIG. 15 is different from step S31 in FIG. 11 in that step S202 indicated by a broken line frame is executed, and steps S104 ′ to S104 ′ indicated by a thick line frame in place of step S32 in FIG. It is characterized in that S136 ′ is executed.

  In step S <b> 202, the call processing unit 54 determines whether the information receiving unit 52 has received the positioning time and the positioning coordinates from the mobile terminal 10. If the determination in step S202 is negative, the process returns to step S30. If the determination is positive, the process proceeds to step S104 '.

  In steps S104 'to S136', the call processing unit 54 performs the same processing as the processing in steps S104 to S136 of Fig. 9 described above.

  As described above, even when the server 50 executes the processes of steps S104 to S136 that have been executed by the mobile terminal 10 in the above embodiment, the same effects as in the above embodiment can be obtained. Moreover, since most of the processing is performed in the server 50 and each table is held in the server 50, the load on the mobile terminal 10 can be reduced. When the mobile terminal 10 alone performs the process of obtaining the return path distance using the result of autonomous navigation, the mobile terminal 10 becomes a mobile information processing apparatus, and when the server 50 alone performs, the server 50 becomes a mobile information processing apparatus. .

  In addition, although the said embodiment and the modification demonstrated the case where the portable terminal 10 calculated a user's positioning coordinate by autonomous navigation, it is not restricted to this. For example, the mobile terminal 10 may perform positioning using only the detection result of the GPS module 21.

  In the above embodiment and the modification, the case where it is determined whether or not the movement trajectory line functions are similar in steps S114 and S114 ′ is not limited to this, and whether or not the movement trajectory line functions are similar. It is not necessary to judge whether. By doing so, redundant trajectories as shown in FIG. 16A can be deleted as shown in FIG. Alternatively, a redundant trajectory as shown in FIG. 16C can be deleted as shown in FIG.

  In addition, although the said embodiment demonstrated the case where the reception system 100 was used in reception of a hospital or a pharmacy, it is not restricted to this. For example, the reception system 100 of the above-described embodiment may be employed in an attraction entrance counter.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the processing apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium (except for a carrier wave).

  When the program is distributed, for example, it is sold in the form of a portable recording medium such as a DVD (Digital Versatile Disc) or a CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.

  The above-described embodiment is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
