Embodiment 1
An embodiment of the present invention will be described with reference to FIGS. 1, 4, and 5.

  (Configuration of Mobile Terminal) FIG. 1 is a block diagram showing a main configuration of the mobile terminal 1 according to the present embodiment. The mobile terminal 1 includes a movement means detection sensor 11, a movement means detection section 12, a host control section 13, a GPS reception section 14, a storage memory 15, a database 16, a display section 17, an audio output section 18, a communication section 19, and an input. The unit 20 is provided. The moving means detection unit 12 and the host control unit 13 are configured by different circuits. The power supply to the moving means detection unit 12 and the power supply to the host control unit 13 can be controlled independently. Therefore, the mobile terminal 1 can independently set the moving means detection unit 12 and the host control unit 13 to the activated state or the sleep state (resting state). Here, the mobile terminal 1 will be described using a smartphone as an example, but is not limited thereto. The mobile terminal 1 may be a mobile terminal such as a mobile phone, a notebook PC, a tablet terminal, an electronic book reader, or a PDA.

  The moving means detection sensor 11 is a sensor for detecting moving means used when a user carrying the mobile terminal 1 moves. Specifically, the moving means detection sensor 11 is an acceleration sensor, a gyro sensor, a geomagnetic sensor, and / or an atmospheric pressure sensor. The movement means detection sensor 11 outputs the detection value of the sensor to the movement means detection unit 12.

  The movement means detection unit 12 includes a movement means identification unit 31 (identification unit) and a change detection unit 32. The moving means detector 12 is composed of one or more circuits.

  The moving means specifying unit 31 specifies the moving means used when the user carrying the mobile terminal 1 moves from the detection value of the moving means detection sensor 11. The moving means refers to moving means such as walking, bicycle, train (railway), automobile, ship, and airplane. The moving means specifying unit 31 can specify the moving means from the detection value of the sensor using a known technique. For example, the moving means specifying unit 31 may specify the moving means from the moving speed. Further, the moving means specifying unit 31 may specify the moving means from the vibration pattern or the change in the tilt of the mobile terminal 1. The moving means specifying unit 31 may specify a state where the user is not moving as a stationary state.

  The change detection unit 32 detects that the user's moving means has been changed. Specifically, the change detection unit 32 compares the current moving unit specified by the moving unit specifying unit 31 with the moving unit specified immediately before (and immediately before), and based on the comparison result, the movement of the user It is determined whether the means has been changed.

  The movement means detection unit 12 outputs information on the identified movement means and information on whether or not the movement means has been changed to the host control unit 13 at a predetermined timing. For example, the moving means detecting unit 12 outputs information on the specified moving means and information on whether or not the moving means has been changed to the host control unit 13 at predetermined intervals (for example, every two minutes). Further, when it is detected that the moving means has been changed, the moving means detecting unit 12 displays information on the specified moving means and information indicating that the moving means has been changed regardless of the predetermined interval. Output to the host controller 13.

  The host control unit 13 includes a user position specifying unit 33, a changed position storage unit 34 (storage unit), a return path information generation unit 35, a notification unit 36, and a time measurement unit 37. The host control unit 13 is composed of one or more circuits. The host control unit 13 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and the CPU executes a program recorded in the ROM, the RAM, and the like. Thereby, each part of the portable terminal 1 is controlled.

  The GPS receiver 14 receives radio waves from a GPS (global positioning system) and outputs the received GPS signal to the host controller 13.

  The storage memory 15 is a storage means for storing information, and may be constituted by, for example, a RAM or a flash memory. The storage memory 15 is configured by a non-volatile memory in which power is continuously supplied even when the host control unit 13 is in a sleep state so that information can be retained.

  The database 16 stores the position of the landmark (latitude / longitude) and the name of the landmark (landmark name) in association with each other. The landmark name is a name of a building, a facility, a famous place, or a historic site that serves as a mark of a certain position (place). Information (corresponding information) between the corresponding position and the landmark name can be acquired from the server by the mobile terminal 1 via the network. Moreover, you may memorize | store in the database 16 of the portable terminal 1 previously. In the database 16, the landmark name is associated with information on the genre corresponding to the landmark name.

  FIG. 4 is a table showing a storage example of landmark names stored in the database 16. As shown in FIG. 4, the name of the landmark is stored in association with the position of the landmark, the genre to which the landmark belongs, and the moving means. For example, a genre “station” is associated with a train station name, a genre “stop” is associated with a bus stop name, and a genre “parking place” is associated with a parking lot name. Yes. The genre is associated with a vehicle (moving means) that can get on and off at the place. For example, the moving means “train” is associated with the genre “station”, the moving means “car” is associated with the genres “stop”, “parking lot”, and “building”. The “airport” is associated with the moving means “ship” and “airplane”, respectively.

  The display unit 17 includes a display device such as a liquid crystal display or an organic EL (electroluminescence) display. The audio output unit 18 includes a speaker and an output terminal for earphone output.

  The communication unit 19 includes an antenna, and communicates with an external device (a base station, another portable terminal, or another communication device) by various types of radio.

  The input unit 20 includes an operation input device such as a touch sensor, a key (button), and a grip sensor, and a voice input device such as a microphone. The touch sensor constitutes a touch panel together with the display of the display unit 17. The grip sensor includes an electrostatic sensor that detects that the casing is gripped by the user. The input unit 20 receives input from the user.

  The user position specifying unit 33 specifies the mobile terminal 1, that is, the current position of the user, from the GPS signal input from the GPS receiving unit 14. The user position specifying unit 33 only needs to be able to specify the current position (range) of the user (mobile terminal 1), and is not limited to one using GPS. For example, the user position specifying unit 33 is a beacon that performs base station information (cell ID (identifier)), Wi-Fi (registered trademark) access point information, and / or BLE (Bluetooth Low Energy (registered trademark)) communication. May be received from the communication unit 19 and the current position may be specified from these. The user position specifying unit 33 specifies the current position of the user at a predetermined timing, for example, at a predetermined interval (for example, every two minutes). Furthermore, when it is detected that the moving means has been changed, the user position specifying unit 33 specifies the current position of the user regardless of the predetermined interval.

  The changed position storage unit 34 causes the storage memory 15 to store the time, the information on the identified moving means, and the information indicating the user's position in association with each other. The changed position storage unit 34 may continue to store a history of information on the moving means and the user's position at each time. Alternatively, when the latest moving unit is the same as the moving unit at the immediately preceding time, the changed position storing unit 34 does not store the moving unit information and the user position information because the moving unit is not changed. May be. That is, the changed position storage unit 34 may be configured to store the time, information on the moving means, and information on the user's position in the storage memory 15 at least when the moving means is changed.

  Further, when it is detected that the user's moving means has been changed, the changed position storage unit 34 saves the information on the user's position in the storage memory 15 as changed position information indicating the position where the moving means has been changed. To do. Furthermore, the change position storage unit 34 stores the moving means before the change (before the change is detected) in the storage memory 15 in association with the change position information.

  The return path information generation unit 35 generates return path information to notify the user based on the changed position information. Specifically, the return path information generation unit 35 uses, as the return path information, the direction and distance from the current position of the user specified by the user position specifying unit 33 to the position indicated by the changed position information (the position where the moving unit has been changed). Generate. The direction to return to the position indicated by the change position information may be a direction (direction) connecting the position indicated by the change position information with a straight line from the current position of the user, or a route (route) to return to the position indicated by the change position information. It may be a direction along. Similarly, the return distance may be a straight line distance from the current position of the user to the position indicated by the changed position information, or may be a distance (path) along the route returning to the position indicated by the changed position information. When notifying the direction and distance along the route, the return path information generation unit 35 acquires map data via the database 16 or the network, and specifies the route from the current position to the position indicated by the changed position information.

  Further, the return path information generation unit 35 acquires a landmark name closer to the position indicated by the change position information from the landmark names stored in the database 16. At this time, the return path information generation unit 35 The landmark name closest to the position indicated by the changed position information is acquired from the landmark names associated with the moving means (moving means before being changed) associated with the changed position information. Then, the return route information generation unit 35 generates return route information including the content of the acquired landmark name, and outputs the return route information to the notification unit 36.

  The notification unit 36 causes the display unit 17 to display the return route information or causes the audio output unit 18 to output the return route information. The notification unit 36 notifies the user of the return route information (including the direction and distance to return to the position indicated by the changed position information and the landmark name) generated by the return route information generation unit 35 at a predetermined timing. The display of the portable terminal 1 is OFF when no operation is performed for a predetermined period. For example, when an operation is performed on the input unit 20 of the mobile terminal 1, the mobile terminal 1 turns on the display of the display unit 17, and the notification unit 36 displays the return direction and distance, and the landmark name on the display unit 17. To display. Further, while the display is ON, the notification unit 36 updates the current position of the user every predetermined period, and causes the display unit 17 to display the updated return direction and distance.

  The time measuring unit 37 measures time according to the notification from the return path information generating unit 35.

  Note that the change detection unit 32 and the movement means identification unit 31 may be realized by software executed in the host control unit 13.

  (Operation Example 1 of Mobile Terminal) FIG. 5 is a flowchart illustrating an example of processing of the mobile terminal 1 according to the present embodiment. As shown in FIG. 5, the moving means specifying unit 31 specifies the current moving means of the user carrying the portable terminal 1 (S1). The change detecting unit 32 compares the current moving unit specified by the moving unit specifying unit 31 with the moving unit specified before (immediately before), and whether the moving unit of the user has been changed based on the comparison result. It is determined whether or not (S2).

  If it is determined by change detection unit 32 that the user's moving means has been changed (YES in S2), user position specifying unit 33 specifies the current position of the user (S3). After S3, the changed position storage unit 34 determines the position of the user specified in S3 at the time at which it was determined in S2, and before it is determined that the user's moving means has been changed in S2 (immediately before ) And stored in the storage memory 15 as changed position information (S4). On the other hand, when it is determined by the change detection unit 32 that the user's moving means has not been changed (NO in S2), the processes after S1 are repeated.

  The return path information generation unit 35 extracts the landmark name of the genre associated with the moving means stored in S4 from the database 16 (S5). After S5, the return path information generation unit 35 associates the landmark name extracted in S5 with the position closest to the user's position saved in S4 (that is, the position where the moving means is changed). The landmark name (for example, station name, parking lot name, facility name, etc.) is acquired (S6). And the return route information generation part 35 produces | generates return route information based on the change position information preserve | saved in S4 (S7). The notification unit 36 notifies the user of the return route information generated in S7 (S8).

  Further, when there is no landmark name of the genre associated with the moving means stored in S4, the landmark name acquired in S5 is a facility name close to the user's position stored in S4. Also good. Note that the process of S5 may be executed after S6.

  In addition, the process of S5-8 may be performed when the display screen of the portable terminal 1 is ON. For example, when an arbitrary button of the mobile terminal 1 is pressed by the user, when the user touches the touch panel or the contact sensor of the mobile terminal 1, the display screen is turned on and the processes of S5 to S8 are executed. In addition, the display screen is turned ON by an alert (for example, an incoming call from another terminal) by an application installed in the mobile terminal 1 or a system alert (for example, a notification indicating that the battery level of the mobile terminal 1 is low). If it is, the process of S8 may not be executed.

  Note that the host control unit 13 also performs display control of the display unit 17. While the user is not using the portable terminal 1, the display screen is OFF and the host control unit 13 is also in the sleep state. In the sleep state, power supply to the circuit (second circuit) that configures the host control unit 13 and executes at least the user position specifying unit 33 is stopped. When the change of the moving means is detected by the moving means detecting unit 12, the circuit (first circuit) that executes the moving means detecting unit 12 activates the second circuit (starts power supply to the power source). The user position specifying unit 33 of the activated second circuit specifies the user position by GPS or the like, and the changed position storage unit 34 stores the user position and the moving means before the change in the storage memory 15. After these processes are finished, the second circuit shifts to the sleep state again. As a result, the amount of power consumed by the second circuit can be reduced. For example, compared with a navigation system that continues to measure the position of the user at intervals of 1 to several seconds, the amount of power reduced by the above configuration is extremely large.

  (Effect) According to the present embodiment, when the change detecting unit 32 detects a change of the moving unit, the position of the user is stored as changed position information indicating the position where the moving unit is changed. Thereafter, in accordance with the current position of the user, return path information including a direction to return to the position indicated by the changed position information is notified to the user. That is, when the user moves on foot from a position where the moving means is changed (for example, the getting-off station), the mobile terminal 1 notifies the user of the direction to return to the getting-off station, the distance, and the name of the getting-off station (landmark name). Can do. Therefore, the user can return to the original disembarking station without getting lost.

  Also, for example, when the user's means of transportation is changed from walking to transportation, and the user rents a vehicle (for example, a bicycle) that does not have a road guidance system at the rental store, the user goes to the rental store on the way home. The changed position information can be used to guide the user.

  Compared with the case where detailed information such as a map is displayed, the information notified to the user is simple information called a direction, so that the user can move depending on intuition. For example, a user who is not good at reading a map or a user who is in a hurry does not need to read the map. Therefore, the user can proceed in the direction desired by the user according to the display on the mobile terminal 1.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  (Operation example 2 of a portable terminal) FIG. 6: is a flowchart which shows an example of a process in case boarding / alighting determination is performed by the portable terminal 1 which concerns on this embodiment. As illustrated in FIG. 6, the moving means specifying unit 31 specifies the current moving means of the user carrying the mobile terminal 1 (S11). The change detecting unit 32 compares the current moving unit specified by the moving unit specifying unit 31 with the moving unit specified immediately before (from immediately before), and from the comparison result, whether or not the user has got off the vehicle. Is determined (S12). More specifically, when the user's moving means is changed from a vehicle (for example, a train, a car, an airplane, a ship, etc.) to a walk, the change detection unit 32 determines that the user has got off the vehicle.

  When change detection unit 32 determines that the user has got off the vehicle (YES in S12), user position specifying unit 33 specifies the current position of the user (S13). After S13, the changed position storage unit 34 determines the position of the user specified in S13 at the time determined in S12, and before (immediately before) the user is determined to get off the vehicle in S2. In association with the moving means, it is stored in the storage memory 15 as getting-off position information (S14).

  After S14, the processes of S5 and S6 are executed as in the first embodiment (not shown). And the return route information generation part 35 produces | generates return route information based on the alighting position information preserve | saved in S14 (S15). The notification unit 36 notifies the user of the return route information generated in S15 (S16). Note that the processes of S15 and S16 may be executed when the display screen of the mobile terminal 1 is ON.

  On the other hand, when change detection unit 32 determines that the user has not got off the vehicle (NO in S12), change detection unit 32 further determines whether or not the user has got on the vehicle (S17). More specifically, when the user's moving means is changed from a walk to a vehicle (for example, a train, an automobile, an airplane, a ship, etc.), the change detection unit 32 determines that the user has got on the vehicle. When change detection unit 32 determines that the user has got on the vehicle (YES in S17), return path information generation unit 35 notifies determination result storage unit 34 of the determination result. Then, the changed position storage unit 34 deletes the getting-off position information stored in S14 from the storage memory 15 (S18). As described above, when the user gets on the vehicle, the portable terminal 1 deletes the information on the old getting-off position in order to stop the guidance to the previous getting-off position and to guide to the latest getting-off position. If NO in S18 and S17, the processing from S11 is repeated.

  (Getting-off position information) FIG. 7 is an example of getting-off position information stored by the mobile terminal 1 that executes the process of FIG. The table shown on the left side of FIGS. 7A and 7B shows the table immediately after the change of the moving means is detected when the change detecting unit 32 detects the change of the moving means used by the user. It shows a history in which the moving means is stored in association with the position and time of the user when the change of the moving means is detected. For this reason, in the table | surface shown on the left side of (a) and (b) of FIG. 7, the time matched with the moving means has no periodicity. Moreover, the table | surface shown to the right side of (a) and (b) of FIG. 7 shows the alighting position information which the change position storage part 34 preserve | saves. As shown in (a) and (b) of FIG. 7, in the history at the latest time among the history in which the moving means indicates walking, the position information and time of the history are moved in the history immediately before the history. Corresponding to the means, it is stored as getting-off position information. That is, in (a) and (b) of FIG. 7, when the change detection unit 32 detects the change of the moving means, the user position specifying unit (position information acquisition unit) 33 acquires the user position information, The change position storage unit 34 stores the moving means detected by the change detection unit 32.

  The table shown on the left side of FIG. 7C associates the position and time of the user when the moving means is specified with the moving means specified by the moving means specifying unit 31 at a predetermined interval (for example, 1 minute). It shows the history saved. In addition, the table shown on the right side of FIG. 7C shows the getting-off position information stored by the changed position storage unit 34. As shown in (c) of FIG. 7, the history position information and time at the latest time when the moving means is walking among the history of changing the moving means from a vehicle (for example, a train) to Corresponding to the moving means in the previous history, it is stored as getting-off position information. That is, in FIG. 7C, the user position specifying unit 33 acquires information on the user position at a predetermined interval, and the change detecting unit 32 associates the moving unit with the position and time at the predetermined interval. The change of the moving means is detected by referring to the history. The change position storage unit 34 stores the moving means detected by the change detection unit 32.

  (Effect) According to the above configuration, when it is determined by the change detection unit 32 that the user has got off the vehicle, the position of the user is stored as getting-off position information indicating the position where the moving means has been changed. For this reason, when returning to the position where the user got off the vehicle, it is determined that the user got off the vehicle, and the getting-off position information can be used to guide the user to the position. Therefore, the user can return to a position where the user can use the moving means used before getting off the vehicle without getting lost.

  For example, if the user's means of transportation is changed from transportation to walking, and there is a business on the unguided land, the user is guided to a place where the transportation used by the user can be used on the return trip In addition, it is possible to use the getting-off position information.

[Modification]
(Operation Example 3 of Portable Terminal) A modification example of the second embodiment will be described. FIG. 8 is a modification of the flowchart shown in FIG. S21 to S24 shown in FIG. 8 are the same as the processes of S11 to S14 shown in FIG. If NO in S22, the processes after S21 are repeated. After S24, the moving means specifying unit 31 specifies the current moving means of the user (S25). Then, the change detecting unit 32 compares the current moving unit specified by the moving unit specifying unit 31 with the moving unit specified before (immediately before), and based on the comparison result, whether the user got on the vehicle. It is determined whether or not (S26).

  If it is determined by change detection unit 32 that the user has got on the vehicle (YES in S26), user position specifying unit 33 specifies the current position of the user, and return path information generating unit 35 determines YES in S26. Information indicating the position of the user specified in this case and information indicating the moving means before (immediately before) the determination process of S26 is acquired (S27). Then, the return route information generation unit 35 determines whether or not the user's position and the moving means match between the latest getting-off point information stored in S24 and the information acquired in S27 (S28). ).

  Note that the user positions determined in S28 do not have to match completely, and are determined to match if they are within a predetermined range. Further, when the location indicated by the latest disembarking point information stored in S24 is a location where a plurality of transportation facilities (routes) can be used, route comparison may be included in the determination processing in S28. In this case, the mobile terminal 1 identifies the route used by the user based on a change in the user's position and the like, and if the route matches, the mobile terminal 1 determines in S28 that the moving means match. In the case of NO in S26, the processes after S25 are repeated.

  When the return route information generation unit 35 determines that the user's position and moving means match between the latest information on the alighting point stored in S24 and the information acquired in S27 (YES in S28), The return path information generation unit 35 notifies the changed position storage unit 34, and the changed position storage unit 34 deletes the latest getting-off position information stored in S24 from the storage memory 15 (S29). Alternatively, the data is saved as the getting-off position information that has already been passed on the return path without being deleted. If NO in S28, the processes after S21 are repeated. After S29, when there is the getting-off position information stored in storage memory 15 (YES in S30), the processes after S25 are repeated. If NO in S30, the process ends.

  (Getting-off position information) FIG. 9 is an example of getting-off position information stored by the mobile terminal 1 that executes the process of FIG.
