Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a conventional vehicle device, when the vehicle is in the power-on state (ignition-on state), the microphone provided in the vehicle is set to be always on. In this case, it is assumed that the vehicle occupants may be concerned that the conversation voices among the occupants in the vehicle are input to the microphone and leaked to the outside, and may want to turn off the microphone from the perspective of privacy. Therefore, it is conceivable to make the on / off state of the vehicle microphone switchable by the operation of the occupants. However, when the on / off state of the vehicle microphone is made switchable in this way, when the microphone is in the off state, hands-free calling using the vehicle microphone cannot be performed. And when an occupant tries to make a hands-free call using the vehicle microphone without noticing that the vehicle microphone is in the off state, since the reason why the hands-free call cannot be made is unknown, there is a risk of giving the occupant a sense of discomfort and uneasiness. Therefore, it is an object of the present application to suppress the occupant from having such a concern. In order to solve the above problems, the present application aims to suppress a decrease in the operability of mobile body communication such as hands-free calling using a microphone provided in a mobile body and in-vehicle video conferencing, and to enable the protection of the privacy of the occupants by turning off the microphone provided in the mobile body. And by extension, it contributes to the development of a sustainable transportation system by further improving traffic safety.

[0005] As an aspect for achieving the above object, there is provided a call support device that supports a mobile call using a mobile microphone provided in the mobile body by a communication terminal brought into the mobile body, the call support device including: a call control unit that transmits the voice input to the mobile microphone to the communication terminal by a mobile communication unit provided in the mobile body to execute the mobile call; a microphone operation control unit that switches the mobile microphone between an on state and an off state according to an operation of a microphone switch provided in the mobile body; and a microphone off notification unit that outputs a microphone off state notification by a mobile notification unit provided in the mobile body when the mobile microphone is in the off state and the mobile call is being made.

[0006] In the above call support device, the mobile notification unit is a display, and the microphone off notification unit may be configured to execute a process of causing the display to display a microphone off notification image indicating that it is necessary to turn on the mobile microphone to make the mobile call as an output of the microphone off state notification.

[0007] In the above call support device, the call control unit may be configured to switch to the mobile call when the mobile microphone is switched from the off state to the on state according to an operation of the microphone switch by the microphone operation control unit while the microphone off notification image is being displayed on the display.

[0008] In the above call support device, the call control unit detects a switch from a terminal call in which the communication terminal makes a call using a terminal microphone provided in the communication terminal to the mobile call, and when the mobile microphone is in the off state and the microphone off notification image is being displayed on the display, if an operation to turn off the mobile microphone is performed by the microphone switch, the call control unit may be configured to maintain the state in which the terminal call is being executed.

[0009] In the above-described call support device, when a communication is established between the communication terminal and the mobile communication unit, when the communication terminal receives an incoming call, an incoming call notification image for notifying the incoming call is displayed on the display, and in response to the incoming call from the incoming call notification image, and when the mobile microphone is in the off state and the microphone off notification image is displayed on the display, when an operation is performed to turn off the mobile microphone by the microphone switch, the incoming call notification image may be continuously displayed on the display.

[0010] In the above-described call support device, when a communication is established between the communication terminal and the mobile communication unit, a call start button for instructing the start of a call by the communication terminal is displayed on the display, and when the call start button is operated and the mobile microphone is in the off state and the microphone off notification image is displayed on the display, when an operation is performed to turn off the mobile microphone by the microphone switch, the call start button may be continuously displayed on the display.

[0011] In the above-described call support device, during the execution of the mobile call, when an operation is performed to turn off the mobile microphone by the microphone switch, a microphone off confirmation image for notifying that the execution of the mobile call becomes impossible when the mobile microphone is turned off may be displayed on the display.

[0012] In the above-described call support device, the display is a touch panel display, and the call control unit causes the display to display the microphone off confirmation image including a microphone off confirmation button for determining an instruction to turn off the mobile microphone, and when the microphone off confirmation button is operated, the mobile microphone may be configured to be in the off state.

[0013] In the above-described call support device, a movement state recognition unit for recognizing that the moving body is in a moving state is provided, and the microphone operation control unit may be configured to prohibit switching to the off state of the moving body microphone when the movement state recognition unit recognizes that the moving body is in a moving state and the moving body call is in progress.

Effect of the Invention

[0014] According to the above-described call support device, it is possible to suppress a decrease in the operability of a moving body call using a microphone provided in the moving body, and to enable protection of the privacy of the occupant by turning off the microphone provided in the moving body.

Embodiments for Carrying Out the Invention

[0016] [1. Configuration of Vehicle] Referring to FIG. 1, the configuration of the vehicle 100 equipped with the call support device 1 according to the present embodiment will be described. The vehicle 100 is a four-wheeled vehicle and corresponds to the moving body of the present disclosure. The vehicle 100 is provided with a call support device 1 and a mobile communication unit 40. The mobile communication unit 40 performs wireless or wired communication with a communication terminal 50 carried by a passenger C (the driver in FIG. 1) of the vehicle 100 and brought into the vehicle 100. The wireless communication is executed according to a short-range communication standard such as Bluetooth (registered trademark).

[0017] In front of the driver's seat 110 of the vehicle 100 (such as a dashboard), a display 30, a mobile microphone 31, and a mobile speaker 32 are provided. The display 30 is a touch panel display in which a touch sensor is arranged on the surface of a flat panel display device such as an LCD or an organic EL. The display 30 corresponds to the moving body notification unit of the present disclosure. Further, the vehicle 100 is provided with a speed sensor 33 that detects the traveling speed of the vehicle 100.

[0018] Although details will be described later, the call support device 1 switches the on and off of the mobile microphone 31 in response to a touch operation on the display 30 by the passenger C. Further, when the communication between the mobile communication unit 40 and the communication terminal 50 is established, the call support device 1 transmits the voice of the passenger C input to the mobile microphone 31 to the communication terminal 50, and outputs the voice of the call partner transmitted from the communication terminal 50 from the mobile speaker 32, and executes control of a mobile call for making a call with the call partner by the communication terminal 50. The mobile call includes various calls executed by the communication terminal 50 using the speaker and microphone provided in the vehicle 100, such as a hands-free call and an in-vehicle video conference. Hereinafter, the case where the passenger C uses the hands-free call function as an example of the mobile call will be described.

[0019] [2. Configuration of Call Support Device] Referring to FIG. 2, the configuration of the call support apparatus 1 will be described. The call support apparatus 1 is connected to a display 30, a mobile microphone 31, a mobile speaker 32, a speed sensor 33, and a mobile communication unit 40. A touch operation signal of the display 30 is input to the call support apparatus 1, and the screen display of the display 30 is controlled by the image data output from the call support apparatus 1. The speech signal of the passenger C input to the mobile microphone 31 is input to the call support apparatus 1, and the voice signal of the call partner of the passenger C output from the call support apparatus 1 is amplified and output by the mobile speaker 32.

[0020] The call support apparatus 1 is a control unit including a processor 10, a memory 20, etc. A program 21 for controlling the call support apparatus 1 is stored in the memory 20. The processor 10 functions as a microphone operation control unit 11, a microphone off notification unit 12, a call control unit 13, and a movement state recognition unit 14 by reading and executing the program 21.

[0021] When the mobile microphone 31 is in the off state, the microphone off notification unit 12 displays the microphone off notification image 60 shown in FIG. 3 on the display 30. The microphone off notification image 60 includes a message section 61 for notifying that the mobile microphone 31 is set to off and that it is necessary to turn on the mobile microphone 31 to perform a mobile hands-free call, a microphone on button 62 for turning on the mobile microphone 31, and a microphone off button 63 for turning off the mobile microphone 31.

[0022] The microphone on button 62 and the microphone off button 63 correspond to the microphone switch of the present disclosure. Note that the microphone on button 62 and the microphone off button 63 may be displayed in an area different from the microphone off notification image 60 of the display 30 without being included in the microphone off notification image 60. Also, the microphone switch may be a physical switch instead of a touch button displayed on the display 30. Further, there may be one microphone switch, and each time the microphone switch is operated, the mobile microphone 31 may be switched between the on state and the off state.

[0023] When the microphone operation control unit 11 operates the microphone on button 62, it turns on the mobile microphone 31, and when the microphone off button 63 is operated, it turns off the mobile microphone 31. The call control unit 13 controls the mobile hands-free call, and also, as shown in FIG. 3, displays a call operation image 70 for instructing the start and end of the mobile hands-free call on the display 30.

[0024] The call operation image 70 includes a call start button for instructing the start (outgoing call) of the mobile hands-free call and a call end button 72 for instructing the end of the mobile hands-free call. The call control unit 13 starts the control of the mobile hands-free call in response to the operation of the call start button 71 and ends the control of the mobile hands-free call in response to the operation of the call end button 72. Further, when the communication terminal 50 is receiving an incoming call (receiving an incoming call from the call partner), the call control unit 13 performs a highlighted display (corresponding to the incoming call notification image of the present disclosure) such as increasing the brightness of the call start button 71 to notify that an incoming call is in progress.

[0025] Also, when the mobile hands-free call is being executed, the call control unit 13 displays a hands-free call in progress image 80 shown in FIG. 4 on the display 30. The hands-free call in progress image 80 includes a message section 81 for notifying that when the mobile hands-free call is in progress and the mobile microphone 31 is set to off, the mobile hands-free call becomes unavailable, the microphone on button 62, and the microphone off button 63.

[0026] When the microphone off button 63 of the hands-free call in progress image 80 is operated, the call control unit 13 displays a microphone off confirmation image 90 shown in FIG. 5 on the display 30. The microphone off confirmation image 90 includes a message section 91 for notifying that when the mobile microphone 31 is turned off, the mobile hands-free call ends and switches to a terminal call, a microphone off confirmation button 92 for confirming the off instruction of the mobile microphone 31, and a cancel button 93 for canceling the off instruction of the mobile microphone 31.

[0027] The call control unit 13 turns off the mobile microphone 31 in response to an operation of the microphone-off confirmation button 92, and maintains the mobile microphone 31 in the on state in response to an operation of the cancel button 93. Hereinafter, details of the processes executed by the microphone operation control unit 11, the microphone-off notification unit 12, and the call control unit 13 will be described. The movement state recognition unit 14 recognizes that the vehicle 100 is traveling (the vehicle 100 is moving) based on the speed detection signal input from the speed sensor 33.

[0028] [3. Corresponding Processing When the Mobile Microphone Is in the Off State] According to the flowchart shown in FIG. 6, the process executed by the call support device 1 when the mobile microphone 31 is in the off state will be described. In step S1 of FIG. 6, the microphone-off notification unit 12 determines whether the mobile microphone 31 is in the off state. When the mobile microphone 31 is in the off state, the process proceeds to step S2, and when the mobile microphone 31 is in the on state, the process proceeds to step S6.

[0029] In step S2, the microphone-off notification unit 12 displays the microphone-off notification image 60 shown in FIG. 3 on the display 30. Through the loop processing of subsequent steps S3 and S4, the microphone operation control unit 11 determines whether the microphone-off button 63 (see FIG. 3) is turned off in step S4, and determines whether the microphone-on button 62 (see FIG. 3) is operated in step S10. Here, regarding the microphone-off notification image 60, it may be always displayed when the mobile microphone 31 is set to off, or it may be displayed only when a selection operation of a function (hands-free call, voice chat application, etc.) using the mobile microphone 31 is detected.

[0030] When the microphone off button 63 is operated, the microphone operation control unit 11 advances the process from step S3 to step S4. In step S4, the call control unit 13 determines whether a terminal call (a call using the microphone 51 and the speaker 52 provided in the communication terminal 50) is being executed by the communication terminal 50. Then, when the terminal call is not being executed, the call control unit 13 advances the process to step S6, and when the terminal call is being executed, the call control unit 13 advances the process to step S5 and continues the terminal call without transmitting and receiving the call voice with the communication terminal 50.

[0031] When the microphone on button 62 is operated, the microphone operation control unit 11 advances the process from step S10 to step S11. In step S11, the microphone operation control unit 11 sets the mobile microphone 31 to on and advances the process to step S6. As a result, the mobile microphone 31 is turned on, and it becomes possible to perform a mobile hands-free call and voice operations on in-vehicle devices (navigation devices, audio devices, air conditioning devices, etc.). In this case, after the mobile microphone 31 is set to on in step S11, when a terminal call is in progress and the mobile call is set to on, the call control unit 13 switches to the mobile hands-free call.

[0032] [4. Incoming Call Handling] According to the flowchart shown in FIG. 7, the handling process when the communication terminal 50 receives an incoming call will be described. In step S20 of FIG. 7, when the call control unit 13 receives an incoming call signal from the communication terminal 50, the process advances to step S21.

[0033] In step S21, the call control unit 13 displays, on the display 30, an image in which the call start button 71 (see FIG. 3) is highlighted as an incoming call image. In the subsequent step S22, the call control unit 13 determines whether there has been a response operation to the incoming call (an operation of the call start button 71 or a response operation on the communication terminal 50). When there has been a response operation, the call control unit 13 advances the process to step S23, and when there has been no response operation, the call control unit 13 advances the process to step S20.

[0034] In the subsequent step S23, the call control unit 13 determines whether the hands-free call is set to on in the communication terminal 50. Then, when the hands-free call is set to on, the call control unit 13 proceeds to step S24, and when the hands-free call is set to off, the call control unit 13 proceeds to step S36. In step S36, the call control unit 13 starts the control of the terminal call and proceeds to step S27. Thereby, the terminal call by the communication terminal 50 is started.

[0035] In step S24, the call control unit 13 determines whether the mobile microphone 31 is in the off state. When the mobile microphone 31 is in the off state, the call control unit 13 proceeds to step S30, and when the mobile microphone 31 is in the on state, the call control unit 13 proceeds to step S25. In step S25, the call control unit 13 ends the display of the incoming call image. In the subsequent step S25, the call control unit 13 transmits the voice of the passenger C input to the mobile microphone 31 to the communication terminal 50, starts the control of the mobile hands-free call, and proceeds to step S27.

[0036] In step S30, the call control unit 13 displays the microphone-off notification image 60 (see FIG. 3) on the display 30 and notifies the passenger C that it is necessary to set the mobile microphone 31 to on to make a mobile hands-free call. In the subsequent step S31, the call control unit 13 determines whether the microphone-off button 63 (see FIG. 3) has been operated. Then, when the microphone-off button 63 has been operated, the call control unit 13 proceeds to step S35, and when the microphone-off button 63 has not been operated, the call control unit 13 proceeds to step S32.

[0037] In step S35, the call control unit 13 continues to display the incoming call image and proceeds to step S27. Thereby, it continuously notifies the passenger C that it is necessary to turn on the mobile microphone to make a mobile hands-free call. Also, in step S32, the call control unit 13 determines whether the microphone on button 62 (see FIG. 3) has been operated. When the microphone on button 62 has been operated, the process proceeds to step S33, and when the microphone on button 62 has not been operated, the process proceeds to step S31.

[0038] In step S33, the call control unit 13 ends the display of the incoming call image. In the subsequent step S34, the call control unit 13 turns on the mobile microphone 31, starts the control of the mobile hands-free call, and proceeds to step S27.

[0039] [5. Outgoing Call Handling] According to the flowchart shown in FIG. 8, the corresponding handling when the passenger C performs an outgoing call (call start) operation will be described. In step S40, the call control unit 13 displays the call start button 71 (see FIG. 3) on the display 30. In the subsequent step S41, the call control unit 13 determines whether the call start button 71 has been operated. When the call start button 71 has been operated, the process proceeds to step S42.

[0040] In step S42, the call control unit 13 determines whether hands-free calling is set to on in the communication terminal 50. Then, when hands-free calling is set to on, the call control unit 13 proceeds to step S43, and when hands-free calling is set to off, the call control unit 13 proceeds to step S56. In step S56, the call control unit 13 starts the control of the terminal call and proceeds to step S46. Thereby, the terminal call by the communication terminal 50 is started.

[0041] In step S43, the call control unit 13 determines whether the mobile microphone 31 is in the off state. When the mobile microphone 31 is in the off state, the process proceeds to step S50. When the mobile microphone 31 is in the on state, the process proceeds to step S44.

[0042] In step S44, the call control unit 13 ends the display of the call start button 71. In the subsequent step S45, the call control unit 13 transmits a signal instructing the communication terminal 50 to make a call to the call partner's terminal, transmits the voice of the passenger C input to the mobile microphone 31 to the communication terminal 50, and outputs the voice of the call partner transmitted from the communication terminal 50 from the mobile speaker 32 to start the control of the mobile hands-free call, and the process proceeds to step S46.

[0043] In step S50, the call control unit 13 displays the microphone-off notification image 60 (see FIG. 3) on the display 30. In the subsequent step S51, the call control unit 13 determines whether the microphone-off button 63 (see FIG. 3) has been operated. When the microphone-off button 63 has been operated, the process proceeds to step S55. When the microphone-off button 63 has not been operated, the process proceeds to step S52.

[0044] In step S55, the call control unit 13 continues to display the call start button 71, and the process proceeds to step S46. By continuing to display the call start button 71, it is possible to continuously notify the passenger C that the mobile microphone 31 can be set to on and switched to the mobile hands-free call.

[0045] In step S52, the call control unit 13 determines whether the microphone-on button 62 (see FIG. 3) has been operated. When the microphone-on button 62 has been operated, the process proceeds to step S53. When the microphone-on button 62 has not been operated, the process proceeds to step S51. In step S53, the call control unit 13 ends the display of the call start button 71. In the subsequent step S54, the call control unit 13 turns on the mobile microphone 31 and starts the control of the mobile hands-free call, and the process proceeds to step S46.

[0046] Response processing during mobile hands-free calls According to the flowchart shown in FIG. 9, the response processing when a mobile hands-free call is being executed will be described. In step S60 of FIG. 8, the call control unit 13 determines whether a mobile hands-free call is being executed. When a mobile hands-free call is being executed, the process proceeds to step S61.

[0047] In step S61, the call control unit 13 displays the hands-free call image 80 (see FIG. 4) on the display 30. In the subsequent step S62, the call control unit 13 determines whether the microphone off button 63 (see FIG. 4) has been operated. When the microphone off button 63 has been operated, the process proceeds to step S70. When the microphone off button 63 has not been operated, the process proceeds to step S63.

[0048] In step S70, the call control unit 13 displays the microphone off confirmation image 90 (see FIG. 5) on the display 30, thereby confirming with the passenger C whether the mobile microphone 31 can really be turned off. Through the loop processing of subsequent steps S71 and S72, the call control unit 13 determines whether the cancel button 93 (see FIG. 5) has been operated in step S71 and whether the microphone off confirmation button 92 (see FIG. 5) has been operated in step S72.

[0049] When the cancel button 93 is operated, the call control unit 13 proceeds from step S71 to step S63. In this case, the mobile microphone 31 is maintained in the on state. When the microphone off confirmation button 92 is operated, the call control unit 13 proceeds from step S72 to step S73. In step S73, the call control unit 13 sets the mobile microphone 31 to off, switches the control from the mobile hands-free call to the terminal call, and proceeds to step S63.

[0050] [7. Other Embodiments] In the above embodiment, the vehicle 100 is shown as the moving body of the present disclosure. However, the moving body of the present disclosure may be any moving body equipped with a moving body microphone and capable of making a hands-free call using the moving body microphone of a communication terminal brought in by a passenger, such as an aircraft or a ship.

[0051] In the above embodiment, as the output of the microphone-off state notification of the present disclosure, the microphone-off notification unit 12 executed the process of displaying the microphone-off notification image 60 on the display 30. As another embodiment, as the output of the microphone-off state notification of the present disclosure, the microphone-off notification unit 12 may execute the process of outputting an audio message notifying that the moving body microphone 31 is in the off state from the moving body speaker 32.
