Description

  The present embodiment as one aspect of the present invention relates to an information processing system capable of providing information on a direction (direction) from a current location to a destination, a control program for a portable terminal, and an electronic device.

  In recent years, mobile terminals have not only a communication function based on a telephone call, but also an address book function, a mail function via a network such as a base station or the Internet, a browser function capable of browsing web pages, and audio data. Music control functions that can listen to music, and functions that can receive terrestrial digital one-segment broadcasting waves.

  In particular, a multifunctional mobile terminal that has functions such as Internet use and schedule management in addition to telephone calls is referred to as a “smartphone”. This smartphone is an intermediate between a conventional portable terminal and a personal computer.

  Among application programs installed in this smartphone, there is a destination instruction application, which is an application program for displaying the direction from the current location to the destination and its distance on the display unit of the smartphone. Thereby, even when the user is in a hurry to the destination, the user can immediately acquire the direction from the current location to the destination via the smartphone.

  In addition, a technique related to a portable navigation device that can display a direction to a destination is known (see Patent Document 1). According to Patent Document 1, an information input device for inputting destination position information related to a destination, a RAM for storing destination position information input via the information input device, and any one of a clock mode and a navigation mode A mode selection button for selecting whether or not, the current time is displayed when the clock mode is selected, and the current position information obtained by the GPS receiver and the purpose stored in the RAM when the navigation mode is selected A portable navigation device including a CPU that calculates a traveling direction from a current position to a destination based on ground position information and displays the traveling direction on a display unit using a display function for displaying the current time is disclosed. ing.

  In addition to the clock function, it has a GPS receiver equipped with an antenna, arithmetic electronics, a compass, a destination coordinate memory, an input element, and a display element.

Japanese Patent Laid-Open No. 11-118506 Special table 2000-512014 gazette

  However, in the case of the destination instruction application mounted on the smartphone, first, in order to display the direction from the current location to the destination on the display unit of the smartphone, the user does not use the smartphone until the destination is reached. You have to carry it with one hand all the time, and you will always be in a situation where one hand is blocked. In particular, since the size of a smartphone is larger than that of a conventional mobile phone, there is a high risk that the user will drop the smartphone during the journey to the destination. If the user is a businessman holding a bag in one hand, the remaining hands are closed with umbrellas when it rains, and the user cannot display the direction to the destination using a smartphone in the first place.

  Secondly, if the user tries to use the destination instruction application on the smartphone during the day, the liquid crystal screen normally used as the display unit of the smartphone is reflected by the sunlight, making it difficult for the user to see. End up. Thirdly, in the case of the destination indication application, the application program merely displays an image related to the needle indicating the direction to the destination on the display unit, and the needle indicating the direction to the destination and its driving mechanism. Since the hardware related to etc. is not provided, once the user exits the destination indication application, the direction displayed on the display unit of the smartphone will naturally disappear, and the user The process by the instruction application must be started again from the beginning. Fourth, if the user turns off the smartphone itself, he / she has to input the password again, and it takes time to start the destination instruction application and display the direction to the destination on the display unit. End up. Fifth, when the user temporarily pauses the destination instruction application to use another application temporarily, and then switches the application to return the destination instruction application, or when the user turns on the power of the smartphone If the power is turned on again after turning OFF and the destination indicating application is resumed from the resting state, the direction to the destination is shifted due to the adjustment by the destination indicating application. Sixth, in the case of the destination instruction application, the direction from the current location to the destination may not be displayed unless the user starts moving in either direction.

  On the other hand, in the technique disclosed in Patent Document 1, a portable precision timepiece inputs a destination in advance using a GPS function and an input element, or inputs data regarding an accurate destination by connecting to a computer. Although it is possible, if the destination is changed suddenly, it cannot be properly handled.

  In the technique disclosed in Patent Document 2, a wristwatch with a navigation function can acquire destination position information via a computer or the like, but it is basically not assumed to carry the computer itself. Therefore, the user cannot set the destination on the go with respect to the wristwatch with the navigation function.

  As described above, for various reasons, there is a problem that it is difficult to simply and appropriately provide information regarding the direction from the current location to the destination.

  With reference to the flowchart of FIG. 7, the destination position information input process in the portable terminal 11 of FIG. 4 will be described. This destination position information input process is performed by reading a dedicated application program stored in advance in the storage unit 40 and executing the read dedicated application program. The destination position information input process is executed prior to the LED lighting information transmission process described with reference to the flowcharts of FIGS. 8 and 9. In the LED lighting information transmission process, the current position information is detected. It may be executed together.

  In step S1, the control unit 39 determines whether or not an instruction to start the destination position information input process is accepted by operating the operation unit 41 by the user, and starts the destination position information input process. It waits until it is determined that the instruction is accepted.

  When an instruction is received in step S1 that the control unit 39 starts the destination position information input process, in step S2, the control unit 39 operates the operation unit 41 in step S2, whereby position information ( Accepts input of location information based on GPS positioning for the destination.

The control unit 39 acquires the connection establishment response supplied from the BT communication module 46. Thereby, the connection by Bluetooth communication is established between the portable terminal 11 and the electronic device 12 which is a counter device.

  When the connection by the Bluetooth communication is established between the mobile terminal 11 and the electronic device 12, the electronic device 12 detects orientation information regarding the electronic device 12 (information regarding the angle of the reference axis direction of the electronic device 12 with respect to the N direction). ) And the transmission of the generated orientation information regarding the electronic device 12 to the mobile terminal 11 sequentially via the BT communication module 75 is started. For example, the electronic device 12 sequentially transmits orientation information regarding the electronic device 12 to the mobile terminal 11 via the BT communication module 75 every time a predetermined timer set in advance expires. The electronic device orientation information transmission process in the electronic device 12 will be described with reference to the flowchart of FIG.

  With reference to the flowchart of FIG. 10, the electronic device direction information transmission processing in the electronic device 12 of FIG. 5 will be described.

  In step S51, the control unit 71 controls the N direction detection unit 77 to extract the N pole and the S pole. The N direction detection unit 77 extracts the N pole and the S pole under the control of the control unit 71, and detects the N direction based on the extracted N pole and S pole. Here, the “N direction” means a direction in which the N pole is viewed from the S pole.

  The N direction detection unit 77 outputs information regarding the detected N direction to the control unit 71. The control unit 71 acquires information related to the N direction from the N direction detection unit 77.

  In step S <b> 52, the control unit 71 calculates the direction (α angle) of the electronic device 12 that is a clock-type device with respect to the N direction.

  FIG. 11 is an explanatory diagram for explaining a calculation method in which the control unit 71 calculates the orientation (α angle) of the electronic device 12 that is a clock-type device with respect to the N direction.

  As shown in FIG. 11, first, it is assumed that the N direction has already been detected by the process of step S51. The “reference axis direction” shown in FIG. 11 means a reference axis direction in the electronic device 12 which is a timepiece-type device. For example, in the case of a timepiece, from 6 o'clock to 12 o'clock (0 o'clock). Corresponds to the viewing direction. Of course, it is only necessary to determine the reference direction of the electronic device 12 that is a clock-type device, and any direction in the electronic device 12 may be determined as the axial direction.

  Here, the physical position of the N-direction detection unit 77 that detects the N direction based on the N pole and the S pole is provided in advance in association with the reference axis direction of the electronic device 12 that is a clock-type device. It has been. Therefore, the relationship between the installation direction of the N direction detection unit 77 in the electronic device 12 and the reference axis direction of the electronic device 12, and the installation direction of the N direction detection unit 77 in the electronic device 12 and the N direction detected thereby. Based on this relationship, the control unit 71 can calculate the difference (α angle) between the reference axis direction of the electronic device 12 and the N direction.

  Based on the calculated α angle, the control unit 71 is information regarding the orientation of the electronic device 12 that is a watch-type device (that is, information regarding the angle of the reference axis direction of the electronic device 12 with respect to the N direction. Is defined as “first difference information” and is simply referred to as “α angle information” for simplicity in the following.

  In the case of FIG. 11, the reference axis direction of the electronic device 12 is a direction rotated α angle clockwise with respect to the N direction. Then, with respect to the N direction, the clockwise direction is set as a positive direction, and the counterclockwise direction is set as a negative direction. This is the same in this specification.

  In step S53, the control unit 71 controls the BT communication module 75 to transmit the generated α angle information (information regarding the orientation of the electronic device 12) to the mobile terminal 11 by Bluetooth communication. The BT communication module 75 transmits α angle information to the mobile terminal 11 under the control of the control unit 71.

  In step S54, after the α angle information is transmitted by the BT communication module 75, the control unit 71 uses a timer (for example, a preset predetermined time T (for example, 10 seconds) that is used when the transmission of the α angle information is resumed. ) Timer).

  In step S55, the control unit 71 determines whether or not the set timer has expired (whether or not a predetermined time T has elapsed). If the control unit 71 determines in step S55 that the timer has expired, the process returns to step S51, and thereafter, the processes after step S51 are executed. Thereby, the electronic device 12 can transmit α angle information to the mobile terminal 11 at every predetermined time T.

  On the other hand, if the control unit 71 determines in step S55 that the timer has not expired, the control unit 71 performs the Bluetooth communication established between the mobile terminal 11 and the electronic device 12 from the mobile terminal 11 in step S56. It is determined whether or not a connection disconnection request for disconnecting is received via the BT communication module 75. When it is determined in step S56 that the control unit 71 has not received the connection disconnection request, the process returns to step S55, and thereafter, the processes after step S55 are repeatedly executed.

  If it is determined in step S56 that the control unit 71 has received the connection disconnection request, the control unit 71 disconnects the connection by Bluetooth communication with the mobile terminal 11 via the BT communication module 75 in step S57. Specifically, the control unit 71 generates a response (connection disconnection response) to the connection disconnection request via Bluetooth communication with the mobile terminal 11, and transmits the generated connection establishment response to the mobile terminal via the BT communication module 75. 11 is transmitted. The BT communication module 75 transmits this connection establishment response to the mobile terminal 11 by Bluetooth communication according to the control of the control unit 71. Thereby, the connection by Bluetooth communication is cut | disconnected between the portable terminal 11 and the electronic device 12. FIG. Thereafter, the electronic device orientation information transmission process in the electronic device 12 of FIG. 5 ends.

  Returning to step S13 of FIG. 8, in step S13, the control unit 39 determines whether or not reception of orientation information regarding the electronic device 12 from the electronic device 12 is started via the BT communication module 46, and the electronic device 12 is started. Wait until it is determined that the reception of the orientation information has started.

  When it is determined in step S13 that the control unit 39 has started receiving the orientation information related to the electronic device 12, the control unit 39 controls the BT communication module 46 in step S14, and the electronic device 12 transmits the orientation information related to the electronic device 12. Complete reception. The BT communication module 46 receives the orientation information related to the electronic device 12 from the electronic device 12 according to the control of the control unit 39, and supplies the received orientation information related to the electronic device 12.

  In step S <b> 15, the control unit 39 acquires orientation information regarding the electronic device 12 supplied from the BT communication module 46.

  In step S16, the control unit 39 controls the N direction detection unit 50 to extract the N pole and the S pole. The N direction detection unit 50 extracts the N pole and the S pole under the control of the control unit 39, and detects the N direction based on the extracted N pole and S pole. As described above, the “N direction” means a direction in which the N pole is viewed from the S pole.

  The N direction detection unit 50 outputs information regarding the detected N direction to the control unit 39. The control unit 39 acquires information related to the N direction from the N direction detection unit 50.

  In step S <b> 17, the control unit 39 activates the GPS receiving unit 48 so that the GPS receiving unit 48 can receive GPS waves (GPS information). In step S <b> 18, the GPS receiver 48 receives GPS waves (GPS information) from a plurality of GPS satellites (not shown) via the GPS antenna 49 according to the control of the controller 39. This GPS information includes, for example, transmission time information from each GPS satellite. Thereafter, the GPS information is input to the control unit 39. And the control part 39 calculates the positional information based on GPS positioning which is the positional information which shows the present location of the portable terminal 11 using the acquired GPS information.

  In step S <b> 19, the control unit 39 reads position information related to the destination stored in the storage unit 40. In step S20 of FIG. 9, the control unit 39 determines the destination from the current location based on the calculated location information based on GPS positioning, which is the location information indicating the current location of the mobile terminal 11, and the read location information on the destination. The direction to the ground is detected, and information on the direction from the current location to the destination is acquired. For example, in the case of FIG. 6, the direction from the current location to the new destination Q point (the direction indicated by the vector AQ) is detected by the control unit 39. At this time, the distance between the current location and the new destination Q point is also calculated. For example, the control unit 39 calculates that the distance from the current location to the destination point Q is 700 meters.

  In step S21, the control unit 39 determines the difference (θ angle) between the N direction and the direction from the current position to the destination based on the acquired information about the N direction and the acquired information about the direction from the current position to the destination. ) Is calculated.

  FIG. 12 is a diagram illustrating an angle θ formed by the N direction and the direction from the current location to the destination. As shown in FIG. 12, the control unit 39 calculates the difference (θ angle) between the N direction and the direction from the current location to the destination, and based on the calculation result, the direction from the N direction and the current location to the destination. Information about the angle θ formed by (which is defined as “second difference information” and hereinafter simply referred to as “θ angle information” as appropriate) is generated.

  In step S <b> 22, the control unit 39 calculates a difference (θ−α) between the θ angle and the α angle based on the α angle information acquired from the electronic device 12 and the generated θ angle information.

  FIG. 13 is an explanatory diagram for explaining the relationship between the θ angle and the α angle. As shown in FIG. 13, the reference axis direction of the electronic device 12 forms an α angle clockwise with respect to the N direction, while the direction from the current location to the destination point Q is relative to the N direction. Since the angle θ is clockwise, the reference axis direction of the electronic device 12 is the angle θ−α clockwise with respect to the direction from the current position to the destination point Q.

  In step S <b> 23, the control unit 39 reads the lighting LED table stored in advance in the storage unit 40.

  FIG. 14 is a lighting LED table showing the correspondence between the θ-α angle and the lighting LED (LED to be lit in the electronic device 12). As shown in FIG. 14, the θ-α angle and the lighting LED (the LED to be turned on in the LED display unit 74 of the electronic device 12) are associated in advance. When the θ-α angle is 0 degree, the lighting LED is turned on. Is the LED at the position of “A” (the LED imitating the letter “A” in FIGS. 2 to 3; the same applies hereinafter), and when the θ-α angle is 45 degrees, the lighting LED is “B When the θ-α angle is 90 degrees, the lighting LED is associated with the LED at the position “C”. As described in the LED display section shown in FIG. 2, the LEDs are arranged in advance with higher definition, and a different LED is associated each time the θ-α angle changes by 30 degrees. You may do it.

  In step S <b> 24, the control unit 39 generates LED lighting information based on the difference (θ−α) between the calculated θ angle and α angle. Specifically, if the θ-α angle is 45 degrees, the LED at the position “B” in the LED display unit 74 of the electronic device 12 is turned on. The LED lighting information for lighting (lighting) the LED at the position “B” in the 12 LED display units 74 is generated. The same applies to other cases.

  The LED lighting information includes information on the distance from the current location to the destination point Q (for example, 700 meters).

  In step S25, the control unit 39 controls the BT communication module 46 to transmit the generated LED lighting information to the electronic device 12 by Bluetooth communication. The BT communication module 46 transmits LED lighting information to the electronic device 12 under the control of the control unit 39.

  The electronic device 12 receives the LED lighting information from the mobile terminal 11 and lights a predetermined LED based on the received LED lighting information. The LED lighting process in the electronic device 12 will be described with reference to the flowchart of FIG.

  With reference to the flowchart of FIG. 15, the LED lighting process in the electronic device 12 of FIG. 5 will be described.

  In step S101, the control unit 71 controls the BT communication module 75 to receive the LED lighting information transmitted from the mobile terminal 11 through Bluetooth communication. The BT communication module 75 receives LED lighting information from the mobile terminal 11 according to the control of the control unit 71 and supplies the received LED lighting information to the control unit 71.

  In step S <b> 102, the control unit 71 acquires LED lighting information from the BT communication module 75. The LED lighting information includes, for example, information for lighting an LED arranged in advance at the position “B” in the LED display unit 74.

  In step S103, the control unit 71 controls the LED display unit 74 to light a predetermined LED based on the acquired LED lighting information. The LED display unit 74 illuminates (emits) a predetermined LED under the control of the control unit 71. For example, in the case where the LED lighting information includes information for lighting the LED arranged at the position “B” in the LED display unit 74 in advance, the LED display unit 74 is displayed as shown in FIG. Turn on the LED located at position “B”.

  In FIG. 16, the LED imitating the letter “B” is displayed in bold letters, which means that the LED arranged at the position “B” is lit. . Further, in the present embodiment, it is only necessary for the electronic device 12 to be able to indicate the direction from the current location to the destination, and basically one or more LEDs for that direction may be displayed.

  Thus, the electronic device 12 can display the direction from the current location to the new destination Q point with respect to the reference axis direction of the electronic device 12 using the LED display unit 74. it can.

  Based on the information on the distance from the current location to the destination Q point included in the LED lighting information, the LED indicating the direction from the current location to the destination is lit, and at the same time the Q point is the current location to the destination. The distance is displayed by LED. As a result, the user can simultaneously know the distance from the current location to the destination point Q.

  Returning to step S26 of FIG. 9, the control unit 39 determines whether or not an instruction to disconnect the Bluetooth communication with the electronic device 12 has been received by operating the operation unit 41 by the user. To do. If the control unit 39 determines in step S26 that the instruction to disconnect the Bluetooth communication with the electronic device 12 has not been accepted, the process returns to step S13 in FIG. The process is executed repeatedly.

  As a result, α angle information (information on the orientation of the electronic device 12) is transmitted from the electronic device 12 to the mobile terminal 11 by Bluetooth communication every predetermined time T (for example, 10 seconds), and the mobile terminal 11 Each time, position information regarding the current location is acquired, LED lighting information is generated based on α angle information and the like, the LED lighting information is transmitted to the electronic device 12, and the electronic device 12 has a predetermined time T (for example, 10). LED can be turned on based on this LED lighting information every second).

  Therefore, the electronic device 12 determines in which direction the direction from the current location to the new destination Q point is with respect to the reference axis direction of the electronic device 12 every predetermined time T (for example, 10 seconds). The LED display unit 74 can be used for display in real time. As a result, the user can confirm the direction to the destination displayed on the electronic device 12 in real time every predetermined time T (for example, 10 seconds).

  On the other hand, when it is determined in step S26 that the control unit 39 has received an instruction to disconnect the Bluetooth communication with the electronic device 12, the control unit 39 performs Bluetooth communication with the electronic device 12 in step S27. A connection disconnection request for requesting connection disconnection by communication is generated. In step S <b> 28, the control unit 39 transmits the generated connection disconnection request to the electronic device 12 via the BT communication module 46. The BT communication module 46 transmits this connection disconnection request to the electronic device 12 by Bluetooth communication according to the control of the control unit 39.

  Thereafter, the BT communication module 46 receives a connection disconnection response, which is a response to the connection disconnection request, from the electronic device 12 via Bluetooth communication, and supplies the received connection disconnection response to the control unit 71. The control unit 71 acquires the connection disconnection response supplied from the BT communication module 46. Thereby, the connection by Bluetooth communication is cut | disconnected between the portable terminal 11 and the electronic device 12 which is an opposing device. Thereafter, the LED lighting information transmission process ends.

LED lighting information or azimuth hand drive information, etc., collectively referring to LED display unit 74, organic EL, liquid crystal, etc. as direction indication means provided in It is defined as

  As described above, for example, when the user is out of a place other than the company, and the destination is suddenly changed from the P point to the Q point while heading to the destination P point (see FIG. 6). Even so, in the information processing system 1 (the portable terminal 11 and the electronic device 12) according to the first embodiment, the portable terminal 11 acquires the position information (GPS information) and the position information ( The direction from the current position to the destination is detected based on the GPS information) and the position information (GPS information) about the destination, and the N direction, which is the direction from the S pole to the N pole, and the reference axis of the electronic device 12 After the first difference information relating to the difference from the reference axis direction is received from the electronic device, second difference information relating to the difference between the N direction and the direction from the current location to the destination is generated, and the first difference information Based on the second difference information, The difference between the direction to the target location and the reference axis direction of the electronic device 12 is calculated, and based on the calculation result, the direction indicating means possessed by the electronic device 12 is assigned to the direction from the current location to the destination and the reference axis of the electronic device 12. Direction instruction information for instructing a predetermined direction based on the difference from the direction is generated, and the direction instruction information is transmitted to the electronic device 12 via short-range wireless communication. The electronic device 12 receives the first difference. Information is generated, and the generated first difference information is transmitted to the mobile terminal 11 via short-range wireless communication, and the direction from the current position to the destination and the reference axis direction serving as the reference axis of the electronic device 12 are Direction indication information for instructing a predetermined direction based on the difference between the mobile terminal 11 and the direction from the current position to the destination and the reference axis direction serving as the reference axis of the electronic device 12 based on the direction indication information Predetermined based on the difference between It is possible to indicate the direction.

  More specifically, in the information processing system 1 (the mobile terminal 11 and the electronic device 12) according to the first embodiment, the mobile terminal 11 acquires GPS information, and the GPS information related to the acquired current location and the destination. Based on the GPS information, the direction from the present location to the destination is detected, and the first difference regarding the difference between the N direction that is the direction from the S pole to the N pole and the reference axis direction that is the reference axis of the electronic device 12 After the difference information is received from the electronic device 12, the second difference information related to the difference between the N direction and the direction from the current location to the destination is generated, and based on the first difference information and the second difference information, The difference between the direction from the current location to the destination and the reference axis direction of the electronic device 12 is calculated, and the direction from the current location to the destination and the electronic device among a plurality of light emitting elements of the electronic device 12 are calculated based on the calculation result. With 12 reference axis directions Lighting information for lighting a light emitting element at a predetermined position previously associated with the difference is generated, and the lighting information is transmitted to the electronic device 12 via short-range wireless communication. And the first difference information thus generated is transmitted to the portable terminal 11 via short-range wireless communication, and the direction from the current location to the destination among the plurality of light emitting elements and the electronic device 12 are transmitted. Lighting information for lighting a light emitting element at a predetermined position previously associated with a difference from the reference axis direction serving as a reference axis is received from the mobile terminal 11, and based on the lighting information, from the current location to the destination It is possible to turn on a light emitting element at a predetermined position that is associated in advance with the difference between the direction and the reference axis direction serving as the reference axis of the electronic device 12.

  As described above, the information processing system 1 (the portable terminal 11 and the electronic device 12) according to the first embodiment can easily and appropriately provide information regarding the direction from the current location to the destination. As a result, the user can immediately and easily know the direction from the current location to the new destination by using the information processing system 1 (the mobile terminal 11 and the electronic device 12) according to the first embodiment. .

  In particular, in the conventional technology, it is assumed that information related to the destination is input in advance before going out, and it is basically not assumed when the destination is suddenly changed. For this reason, the conventional technique cannot cope with the case where the destination is suddenly changed. On the other hand, according to the information processing system 1 according to the first embodiment, as long as it is in an environment that can be connected to the mobile communication network NW, location information regarding the destination is obtained at any time, and from the current location It is possible to detect the direction to the destination.

  In addition, in the case of the above destination instruction application installed in a conventional smartphone, first, the smartphone must be carried with one hand until reaching the destination, and secondly, the display of the smartphone There is a problem that a liquid crystal screen that is normally used as a part is reflected by the sun light, making it difficult for the user to see.

  On the other hand, in the information processing system 1 according to the first embodiment, the electronic device 12 is a watch-type device, which is attached to the user by the attachment portion 12b. This eliminates the need for the user to carry the electronic device 12 by hand until reaching the destination. In addition, in the case of the information processing system 1 according to the first embodiment, the mobile terminal 11 and the electronic device 12 can exchange data by short-range wireless communication. It is no longer necessary to hold it by hand, and it can be put in a bag.

(Second Embodiment)
In the information processing system 1 according to the first embodiment, the electronic device 12 lights a predetermined LED provided in the LED display unit 74 based on the LED lighting information transmitted from the mobile terminal 11 ( However, the present invention is not limited to such a case. For example, the electronic device 12 is provided with an azimuth needle driving unit and an azimuth needle, and the azimuth needle is set to a predetermined position based on the LED lighting information transmitted from the mobile terminal 11. You may make it drive to a position. Details of the information processing system 1 according to the second embodiment will be described below.

  Also in the case of the second embodiment, the processes in the information processing system 1 (the mobile terminal 11 and the electronic device 12) in the first embodiment described with reference to FIGS. 1 to 16 are basically the same. The common configuration and processing are omitted.

  FIG. 17 is a block diagram illustrating an internal configuration of the electronic device 12 according to the second embodiment. The electronic device 12 includes a control unit 71, a storage unit 72, an input unit 73, a BT communication module 75, an infrared communication module 76, an N direction detection unit 77, a direction needle drive unit 101, and a direction needle 102. Note that, in the configuration shown in FIG. 17, the same components as those in FIG.

  The azimuth needle drive unit 101 is a drive mechanism for driving the azimuth needle 102. The azimuth needle 102 is driven to a predetermined position by driving the azimuth needle driving unit 101.

  FIG. 18 is a configuration example of the azimuth needle 102 provided on the main body 12a of the electronic device 12 of FIG. As shown in FIG. 18, the direction from the current position to the destination is indicated by the direction hand 102.

  The second embodiment is basically the same as the first embodiment. However, in the case of the second embodiment, the means for indicating the direction from the current location to the destination is not the LED lighting (display), but a direction hand, and accordingly, information transmitted from the portable terminal 11 to the electronic device 12 is transmitted. It becomes direction needle drive information. This azimuth drive information transmission process is shown in FIG. 19 and FIG.

  With reference to the flowcharts of FIGS. 19 and 20, the azimuth drive information transmission process in the mobile terminal 11 of FIG. 4 in the second embodiment will be described. 19 and 20 is basically the same as the process of FIG. 8, only steps S 213 and S 214 of FIG. 20 that are different processes will be described, and the other processes will be omitted.

  In step S213 of FIG. 20, the control unit 39 generates azimuth needle drive information based on the difference (θ−α) between the calculated θ angle and α angle. Specifically, if the θ-α angle is 93 degrees, the azimuth needle 102 of the electronic device 12 is driven by the azimuth needle drive unit 101 to a position that makes 93 degrees with the reference axis. For this reason, this azimuth drive information includes information on the difference between the θ angle and the α angle, as well as information for instructing driving of the azimuth. The same applies to other cases.

  In step S214, the control unit 39 controls the BT communication module 46 to transmit the generated azimuth needle drive information to the electronic device 12 by Bluetooth communication. The BT communication module 46 transmits azimuth needle drive information to the electronic device 12 under the control of the control unit 39.

  With reference to the flowchart of FIG. 21, the azimuth | direction needle drive process in the electronic device 12 of FIG. 17 is demonstrated.

  In step S251, the control unit 71 controls the BT communication module 75 to receive the azimuth hand drive information transmitted from the mobile terminal 11 through Bluetooth communication. The BT communication module 75 receives azimuth needle drive information from the mobile terminal 11 according to the control of the control unit 71, and supplies the received azimuth needle drive information to the control unit 71.

  In step S <b> 252, the control unit 71 acquires azimuth needle drive information from the BT communication module 75.

  In step S253, the control unit 71 controls the azimuth needle drive unit 101 and drives the azimuth needle 102 to a predetermined position based on the azimuth needle drive information. For example, if the θ-α angle is 93 degrees, the azimuth needle 102 of the electronic device 12 is driven by the azimuth needle drive unit 101 to a position that forms 93 degrees with the reference axis.

  Thereby, the electronic device 12 can indicate the direction from the current location to the destination with the azimuth needle 102. In particular, when information about the θ-α angle is included as it is in the azimuth needle drive information transmitted from the mobile terminal 11 to the electronic device 12, the electronic device 12 can more accurately indicate the direction from the current location to the destination. Is possible. Of course, the present invention is not limited to this case, and the direction hand drive information transmitted from the portable terminal 11 to the electronic device 12 is divided every 30 degrees (or every 45 degrees) according to the θ-α angle. Also good.

  As described above, the information processing system 1 (the mobile terminal 11 and the electronic device 12) according to the second embodiment can easily and appropriately provide information regarding the direction from the current location to the destination. As a result, the user can immediately and easily know the direction from the current location to the new destination by using the information processing system 1 (the mobile terminal 11 and the electronic device 12) according to the first embodiment. .

(Third embodiment)
By the way, in both cases of the first embodiment and the second embodiment, information on the direction from the current location to the destination is provided by LED lighting or a direction hand so that the destination is indicated directly. However, it is not limited to such a case.

  For example, the path from the current location to the destination may be complicated, and it may be necessary to take a detour. In such a case, it may be inconvenient for some users to simply indicate the direction from the current location to the destination.

  Therefore, the mobile terminal 11 searches for the route to the destination using the navigation function, and sets the intersection of the route closest to the current location (that is, the point where the user's traveling direction is changed or a branch point) as the intermediate destination. Then, information regarding the direction from the current location to the intermediate destination is transmitted to the electronic device 12. The electronic device 12 turns on the LED or drives the direction hand based on the information about the direction from the current location to the intermediate destination and the current location.

  Then, each time the user reaches the intermediate destination, the mobile terminal 11 repeatedly sets a new intermediate destination, and transmits information related to the direction from the current location to the intermediate destination to the electronic device 12.

  As a result, when the path from the current location to the destination is complicated, the user can easily know the direction from the current location to the intermediate destination, and finally know the direction to the destination reliably. be able to. Details of the information processing system 1 according to the third embodiment will be described below.

  In addition, 3rd Embodiment can also be implemented based on 1st Embodiment, and can also be implemented based on 2nd Embodiment. In the following, a third embodiment based on the first embodiment will be described. In the case of the third embodiment, the hardware configuration and processing procedure in the information processing system 1 in the first embodiment are basically the same, and the description thereof will be omitted as appropriate.

  With reference to the flowcharts of FIGS. 22 and 23, the LED lighting information transmission processing in the mobile terminal 11 of FIG. 4 will be described. The processes in steps S301 to S308, S311 to S317, and S321 to S322 in FIGS. 22 and 23 are basically the same as the processes in steps S11 to S18, S20 to S26, and S27 to S28 in FIG. There will be no further explanation.

  In step S309, the control unit 39 of the mobile terminal 11 reads the position information related to the destination stored in the storage unit 40, and uses the navigation function to read the position information related to the read destination and the acquired current location. The route from the current location to the destination is searched via the base station BS and the mobile communication network NW based on the positional information on the route, and the route search result is acquired.

  FIG. 24 is a specific example of the route from the current location to the destination obtained by route search. As shown in FIG. 24, a route from the current location A to the destination Q is acquired via the base station BS and the mobile communication network NW. In the case of FIG. 24, the route from the current location A to the destination Q has k points, L points, M points, N points, O points, and Z points as points to change directions (or branch points). ing.

  In addition, in the route search result acquired by the control unit 39 in step S309, the position information (point k, L point, M point, N point, O point, and Z point) as shown in FIG. Location information based on GPS positioning).

  In step S310 in FIG. 23, the control unit 39 extracts the branch point closest to the current location based on the position information regarding the current location and the route search result, and sets the branch point as an intermediate destination. In the case of FIG. 24, first, the control unit 39 sets a point K, which is the closest branch point on the route from the current location A, as an intermediate destination.

  Thereafter, in step S311, the control unit 39 determines the intermediate destination from the current location based on the location information based on the GPS positioning, which is the location information indicating the calculated current location of the mobile terminal 11, and the location information on the set intermediate destination. The direction to the ground is detected, and information on the direction from the current location to the intermediate destination is acquired. For example, in the case of FIG. 24, the direction from the current location to the K point that is the intermediate destination is detected by the control unit 39.

In step S312, the control unit 39 determines the difference between the N direction and the direction from the current position to the intermediate destination based on the acquired information about the N direction and the acquired information about the direction from the current position to the intermediate destination ( θ angle) is calculated. Thereafter, the processing after step S313 is executed, and the LED lighting information is transmitted to the electronic device 12 in step S316. In addition, the information regarding the difference between the N direction and the direction from the current position to the intermediate destination is defined as “third difference information”. Thereafter, the electronic device 12 receives the LED lighting information from the mobile terminal 11 and is received. Based on the LED lighting information, a predetermined LED indicating the direction from the current location to the intermediate destination is turned on.

  As a result, when the path from the current location to the destination is complicated, and the user has to take a detour, the user can know the direction from the current location to the intermediate destination.

  If it is determined in step S317 that the control unit 39 has not received an instruction to disconnect the connection with the electronic device 12 via Bluetooth communication, the process proceeds to step S318.

  In step S 318, the GPS receiver 48 receives GPS waves (GPS information) from a plurality of GPS satellites (not shown) via the GPS antenna 49 according to the control of the controller 39. Thereafter, the GPS information is input to the control unit 39. And the control part 39 calculates the positional information based on GPS positioning which is the positional information which shows the present location of the portable terminal 11 using the acquired GPS information.

  In step S319, the control unit 39 determines whether or not the current location matches the intermediate destination based on the set location information regarding the intermediate destination and the location information indicating the current location (that is, the user has reached the intermediate destination). Whether or not). In the determination processing in step S319, not only when the current location and the intermediate destination are completely coincident with each other based on the GPS positioning, but within a predetermined distance (for example, 2 meters or 5 meters) from the intermediate destination. In this case, it is determined that “the current location matches the intermediate destination”. The same applies to the determination process in step S320. The predetermined distance can be arbitrarily determined. If it is determined that the current location does not match the intermediate destination, the process returns to step S318, and the same processing is repeated until it is determined that the current location matches the intermediate destination.

  If the control unit 39 determines in step S319 that the current location matches the intermediate destination, the control unit 39 determines in step S320 whether the current location (intermediate destination) matches the final destination (ie, current location = intermediate). It is determined whether or not (the destination = the destination). For example, in the case of FIG. 24, if the currently set intermediate destination is K point, the current location (intermediate destination) does not match the final destination Q point, and the intermediate point such as L point after K point. Since the destination can be newly set, it is determined that the current location (intermediate destination) does not match the final destination.

  On the other hand, for example, in the case of FIG. 24, when the currently set intermediate destination is the Q point, it is determined that the current location (intermediate destination) matches the final destination.

  When the control unit 39 determines in step S320 that the current location (intermediate destination) does not match the final destination, the processing returns to step S310, and the processing from step S310 is repeatedly executed. As a result, on the route from the current location to the final destination, the new location is repeated until the current location (intermediate destination) matches the final destination (until the intermediate destination cannot be set). Intermediate destinations are set. Therefore, the user can follow the route from the current location to the final destination.

  If the control unit 39 determines in step S320 that the current location (intermediate destination) matches the final destination, the process proceeds to step S321, and a connection disconnection request is generated to end the LED lighting information transmission process. Is done.

  As described above, when the information processing system 1 (the mobile terminal 11 and the electronic device 12) according to the third embodiment provides information on the direction from the current location to the destination, the information processing system 1 on the route from the current location to the destination Can be repeatedly provided until the final destination is reached, by setting the branch point existing at the intermediate destination as the intermediate destination. As a result, the user can immediately and easily know the direction from the current location to the destination by using the information processing system 1 (the portable terminal 11 and the electronic device 12) according to the third embodiment. Note that in any of the information processing system 1 according to the first embodiment to the information processing system 1 according to the third embodiment, the mobile terminal 11 includes the GPS receiver 48 so that the mobile terminal 11 is located from the current location. The direction to the destination is calculated and LED lighting information or direction hand drive information is generated. However, the present invention is not limited to such a case.

  For example, the electronic device 12 includes a GPS receiver, and the electronic device 12 calculates the direction from the current position to the destination, generates LED lighting information or direction hand drive information, and turns on the LED or drives the direction hand. You may make it perform all the processes until. In this case, connection by Bluetooth communication with the mobile terminal 11 is not necessary. Thereby, the problem that the process by the destination instruction application must be performed again from the beginning in the smartphone is solved.
