[0012] Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

[0013] <First embodiment> A wearable device 1 according to this embodiment will be described with reference to FIGS.

[0014] <Wearable device 1 configuration> As shown in FIG. 1, the wearable device 1 includes a connecting band 11 that extends in a curved shape so as to envelop the side and back of the head. The wearable device 1 includes protruding frames 12R and 12L that are formed on both sides of the connecting band 11 in the longitudinal direction and protrude toward the temporal region in front of or behind the user's ears. The user wears the wearable terminal 1 by hanging the protruding frames 12L and 12R on the left and right ears, respectively.

[0015] As shown in FIG. 2, the wearable terminal 1 includes a bone conduction unit 13, a first control unit 100, a second control unit 200, a third control unit 300, and a quasi-electrostatic field generating unit 14.

[0016] In this embodiment, the wearable terminal 1 includes a bone conduction section 13 that is provided on the inner surface of the tip of the protruding frame 12, for example, and is brought into close contact with the side of the user's head to transmit sound to the user. As shown in FIG. 1, the wearable terminal 1 includes a bone conduction unit 13R that is brought into close contact with the right side of the user's head, and a bone conduction unit 13L that is brought into close contact with the left side of the user's head. The bone conduction unit 13 is constituted by, for example, a vibrator, and is brought into contact with the side of the user's head to transmit sound without passing through the user's eardrum. The bone conduction unit 13L and the bone conduction unit 13R are controlled by, for example, a first control unit 100 and a second control unit 200 described later, and vibrate at, for example, 10 MHz. The vibrations generated by the bone conduction units 13L and 13R stimulate, for example, the hairs in the user's inner ear through the user's skull.

[0017] In this embodiment, the first control unit 100 is, for example, a control unit provided near the tip of the protruding frame 12R, and controls the vibration of the bone conduction unit 13 and the direction of the current flowing in the quasi-electrostatic field generating unit 14 described later. The control of the first control unit 100 will be described later.

[0018] In this embodiment, the second control unit 200 is, for example, a control unit provided near the tip of the protruding frame 12L, and, for example, controls the vibration of the bone conduction unit 13L and the direction of the current flowing in the quasi-electrostatic field generating unit 14 described later in accordance with instructions from the first control unit 100. The control of the second control unit 200 will be described later.

[0019] In this embodiment, the third control unit 300 is, for example, a control unit provided at the back of the user's head, and controls the direction of the current flowing in the quasi-electrostatic field generating unit 14 described later, for example, in accordance with instructions from the first control unit 100. The control of the third control unit 300 will be described later.

[0020] The quasi-electrostatic field generating units 14 are arranged in a strip shape on the connecting band 11 . As shown in FIG. 1, in this embodiment, the quasi-electrostatic field generating unit 14 is arranged in a band shape on the connecting band 11 and the protruding frame 12, and includes a quasi-electrostatic field generating unit 14R arranged in a band shape from the back of the user's head to the right head, and a quasi-electrostatic field generating unit 14L arranged in a band shape from the back of the user's head to the left head. In this embodiment, the quasi-electrostatic field generating unit 14 changes the quasi-electrostatic field generated around the user's head, for example, under the control of the first control unit 100, the second control unit 200, and the third control unit 300. In this embodiment, the quasi-electrostatic field generating unit 14 changes the quasi-electrostatic field around the user's head, for example, to stimulate the inner ear hair and body hair of the user wearing the wearable terminal 1.

[0021] <Configuration of the first control unit 100> As shown in FIG. 3, the first control unit 100 includes a processor 110, a memory 120, a communication unit 130, and a first power supply circuit 140.

[0022] In this embodiment, the processor 110 controls, for example, the vibration of the bone conduction unit 13 and the direction of a current flowing in the quasi-electrostatic field generating unit 14 described later. The configuration of the processor 110 will be described later.

[0023] The memory 120 includes a read only memory (ROM) and a random access memory (RAM), neither of which are shown. The memory 120 stores, for example, a control program, preset information to be referenced when controlling the current flowing through the quasi-electrostatic field generating unit 14, and various data received from the processor 110.

[0024] The communication unit 130 is, for example, a short-range wireless communication unit such as Bluetooth (registered trademark), and connects to the second control unit 200, the third control unit 300, and the sensing device 500 to transmit and receive information. In this embodiment, the communication unit 130 transmits, for example, information relating to the control for generating a change in the quasi-electrostatic field to the second control unit 200 and the third control unit 300. In this embodiment, the communication unit 130 receives external environment information about the surroundings of the vehicle from the sensing device 500, for example. The external environment information received from the sensing device 500 will be described later.

[0025] In this embodiment, the first power supply circuit 140 switches the output to the quasi-electrostatic field generating unit 14R in accordance with an instruction from the processor 110, for example. In this embodiment, the first power supply circuit 140 outputs either a predetermined voltage, 0 (V), or an open state (for example, making the input impedance infinite) according to an instruction from the processor 110, for example.

[0026] <Configuration of the Processor 110> As shown in FIG. 3, the processor 110 includes an external environment information acquisition unit 111 and a terminal control unit 112. Each unit of the processor 110 and the memory 120 transmit and receive various types of information via a bus line BL1.

[0027] The external environment information acquisition unit 111 acquires external environment information about the surroundings of the vehicle from the sensing device 500 via the communication unit 130 . In this embodiment, the sensing device 500 is a device installed in a vehicle driven by a user wearing the wearable terminal 1, and detects the position of approaching vehicles, etc., based on the output of sensors such as cameras and millimeter wave radar installed in the vehicle. In this embodiment, the external environment information acquisition unit 111 acquires, for example, information on the position of an approaching vehicle as the external environment information. The external environment information acquisition unit 111 transmits the acquired external environment information to a terminal control unit 112, which will be described later, via the bus line BL1.

[0028] The terminal control unit 112 controls the entire first control unit 100 in accordance with a control program stored in the memory 120 . In this embodiment, the terminal control unit 112 transmits, for example, an instruction to acquire external environment information to the external environment information acquisition unit 111. In this embodiment, the terminal control unit 112 controls, for example, the sounds output from the bone conduction unit 13R and the bone conduction unit 13L. In this embodiment, the terminal control unit 112 causes the bone conduction unit 13R and the bone conduction unit 13L to output sound based on the external environment information received from the external environment information acquisition unit 111, for example. In this embodiment, when the terminal control unit 112 determines that the approaching vehicle is traveling on the right side, it vibrates the bone conduction unit 13R at 10 MHz, for example. In this embodiment, for example, when the terminal control unit 112 determines that the approaching vehicle is traveling on the left side, it transmits an instruction to vibrate the bone conduction unit 13L to the second control unit 200 described later. In this embodiment, for example, when an approaching vehicle cannot be detected, the terminal control unit 112 stops the vibration of the bone conduction unit 13R. In this embodiment, for example, when the terminal control unit 112 cannot detect an approaching vehicle, it transmits an instruction to stop vibration of the bone conduction unit 13L to the second control unit 200 described later.

[0029] In this embodiment, the terminal control unit 112 detects the possibility of a danger occurring based on, for example, the external environment information acquired by the external environment information acquisition unit 111, and executes control to change the generation of the quasi-electrostatic field in the direction in which the danger will occur. In this embodiment, for example, when the terminal control unit 112 detects that the position of an approaching vehicle is within a predetermined distance (for example, within 100 m) based on external environment information, the terminal control unit 112 determines the operation mode of the quasi-electrostatic field generating unit 14 based on the position and traveling direction of the vehicle. In this embodiment, the terminal control unit 112 transmits information about the determined operation mode to the second control unit 200 and the third control unit 300 via the communication unit 130, for example. In this embodiment, the terminal control unit 112 controls the output of the first power supply circuit 140, for example, based on the determined operation mode. The above operating modes will be described later.

[0030] <Configuration of second control unit 200> As shown in FIG. 3, the second control unit 200 includes a processor 210, a memory 220, a communication unit 230, and a second power supply circuit 240.

[0031] In this embodiment, the processor 210 controls, for example, the vibration of the bone conduction section 13L and the direction of the current flowing in the quasi-electrostatic field generating section 14. The configuration of the processor 210 will be described later.

[0032] The memory 220 includes a read only memory (ROM) and a random access memory (RAM), neither of which are shown. The memory 220 stores, for example, a control program, preset information to be referred to when controlling the current flowing through the quasi-electrostatic field generating unit 14, and various data received from the processor 210.

[0033] The communication unit 230 is, for example, a short-range wireless communication unit such as Bluetooth (registered trademark), and connects to the first control unit 100 to perform communication. In this embodiment, the communication unit 230 receives, for example, from the first control unit 100, an instruction regarding the operation of the bone conduction unit 13L. In this embodiment, the communication unit 230 receives, for example, information regarding the operation mode from the first control unit 100.

[0034] In this embodiment, the second power supply circuit 240 switches the output to the quasi-electrostatic field generating unit 14L in accordance with an instruction from the processor 210, for example. In this embodiment, the second power supply circuit 240 outputs either a predetermined voltage, 0 (V), or an open state (eg, a state in which the input impedance is infinite) according to an instruction from the processor 210, for example.

[0035] <Configuration of the processor 210> As shown in FIG. 3, the processor 210 includes a control unit 212 . The control unit 212 and the memory 120 transmit and receive various types of information via a bus line BL2.

[0036] The control unit 212 controls the entire second control unit 200 in accordance with a control program stored in the memory 220 . In this embodiment, the control unit 212 performs control to output sound from the bone conduction unit 13L based on an instruction regarding the operation of the bone conduction unit 13L received from the first control unit 100, for example. In this embodiment, for example, when the control unit 212 receives an instruction to vibrate the bone conduction unit 13L from the first control unit 100, the control unit 212 vibrates the bone conduction unit 13L at 10 MHz. In this embodiment, for example, when the control unit 212 receives an instruction to stop vibration from the first control unit 100, it stops the vibration of the bone conduction unit 13L. In this embodiment, the control unit 212 controls the output of the second power supply circuit 240 based on information relating to the operation mode received from the first control unit 100, for example. In this embodiment, the control unit 212 controls the output of the second power supply circuit 240 based on the information on the operation mode received from the first control unit 100. The above operating modes will be described later.

[0037] <Configuration of the third control unit 300> As shown in FIG. 3, the third control unit 300 includes a processor 310, a memory 320, a communication unit 330, and a third power supply circuit 340.

[0038] In this embodiment, the processor 310 controls, for example, the direction of a current flowing through the quasi-electrostatic field generating unit 14 . The configuration of the processor 310 will be described later.

[0039] The memory 320 includes a read only memory (ROM) and a random access memory (RAM), neither of which are shown. The memory 320 stores, for example, a control program, preset information to be referred to when controlling the current flowing through the quasi-electrostatic field generating unit 14, and various data received from the processor 310.

[0040] The communication unit 330 is, for example, a short-range wireless communication unit such as Bluetooth (registered trademark), and connects to the first control unit 100 to perform communication. In this embodiment, the communication unit 230 receives, for example, information regarding the operation mode from the first control unit 100.

[0041] In this embodiment, the third power supply circuit 340 switches the output to the quasi-electrostatic field generating unit 14L and the quasi-electrostatic field generating unit 14R in accordance with an instruction from the processor 310, for example. In this embodiment, the third power supply circuit 340 outputs either a predetermined voltage, 0 (V), or an open state (eg, a state in which the input impedance is infinite) according to an instruction from the processor 310, for example.

[0042] <Configuration of the processor 310> As shown in FIG. 3, the processor 310 includes a control unit 312 . The control unit 312 and the memory 320 transmit and receive various information via a bus line BL3.

[0043] The control unit 312 controls the entire third control unit 300 in accordance with a control program stored in the memory 320 . In this embodiment, the control unit 312 controls the output of the third power supply circuit 340 based on information relating to the operation mode received from the first control unit 100, for example. The operating modes will be described later.

[0044] <Control for each operation mode> In this embodiment, the terminal control unit 112 detects the possibility of a danger occurring based on the external environment information acquired by the external environment information acquisition unit 111, and executes control to change the generation of the quasi-electrostatic field in the direction in which the danger will occur. In this embodiment, the terminal control unit 112 controls the output states of the first power supply circuit 140, the second power supply circuit 240, and the third power supply circuit 340, and controls the direction of the current flowing to the quasi-electrostatic field generating unit 14L and the quasi-electrostatic field generating unit 14R.

[0045] As shown in FIG. 4, in this embodiment, the terminal control unit 112 determines the operation mode by referring to the approaching state of a vehicle detected based on, for example, external environment information. For example, when it is determined that there is no approaching vehicle or the like based on the external environment information acquired from the external environment information acquisition unit 111, the terminal control unit 112 sets the operation mode to operation mode 1. For example, when a vehicle approaching from the front left is detected, the terminal control unit 112 sets the operation mode to operation mode 2. For example, when a vehicle approaching from the rear left is detected, the terminal control unit 112 sets the operation mode to operation mode 3. For example, when a vehicle approaching from the front right is detected, the terminal control unit 112 sets the operation mode to operation mode 4. For example, when a vehicle approaching from the rear right is detected, the terminal control unit 112 sets the operation mode to operation mode 5. For example, when the terminal control unit 112 detects that a vehicle traveling on the left rear is approaching while moving from left to right, it sets the operation mode to operation mode 2 during the period when the vehicle is traveling on the left rear, and sets the operation mode to operation mode 5 during the period when the vehicle is traveling and moving to the right rear. The terminal control unit 112 transmits the determined operation mode to the second control unit 200 and the third control unit 300 via the communication unit 130.

[0046] In this embodiment, the terminal control unit 112 controls the output states of the first power supply circuit 140, the second power supply circuit 240, and the third power supply circuit 340 so that, for example, the traveling direction of an approaching vehicle and the direction of the current flowing to the quasi-electrostatic field generating unit 14L and the quasi-electrostatic field generating unit 14R are the same. In this embodiment, the terminal control unit 112, the control unit 212, and the control unit 312 control the output of the first power supply circuit 140, the second power supply circuit 240, and the third power supply circuit 340, respectively, according to, for example, an operating mode determined by the terminal control unit 112.

[0047] In this embodiment, the terminal control unit 112, the control unit 212, and the control unit 312 control the output of the first power supply circuit 140, the second power supply circuit 240, and the third power supply circuit 340 based on preset information stored in the memory 120, the memory 220, and the memory 320, as shown in FIG. 5.

[0048] When the operating mode is operating mode 1, the terminal control unit 112 sends an instruction to the first power supply circuit 140 to set it to an open state, the control unit 212 sends an instruction to the second power supply circuit 240 to set it to an open state, and the control unit 312 sends an instruction to the third power supply circuit 340 to set it to an open state. As a result, in the case of operation mode 1, the current flowing through the quasi-electrostatic field generating unit 14L and the quasi-electrostatic field generating unit 14R becomes zero, and the generation of the quasi-electrostatic field stops.

[0049] When the operating mode is operating mode 2, the terminal control unit 112 sends an instruction to the first power supply circuit 140 to put it in an open state, the control unit 212 sends an instruction to the second power supply circuit 240 to output a predetermined voltage, and the control unit 312 sends an instruction to the third power supply circuit 340 to output 0 (V). As a result, in the case of the operation mode 2, a current flows from the third power supply circuit 340 to the quasi-electrostatic field generating unit 14L and then to the second power supply circuit 240.

[0050] When the operating mode is operating mode 3, the terminal control unit 112 sends an instruction to the first power supply circuit 140 to put it in an open state, the control unit 212 sends an instruction to the second power supply circuit 240 to output 0 (V), and the control unit 312 sends an instruction to the third power supply circuit 340 to output a predetermined voltage. As a result, in the case of operation mode 3, a current flows from the second power supply circuit 240 to the quasi-electrostatic field generating unit 14L and then to the third power supply circuit 340.

[0051] When the operating mode is operating mode 4, the terminal control unit 112 sends an instruction to the first power supply circuit 140 to output a predetermined voltage, the control unit 212 sends an instruction to the second power supply circuit 240 to put it in an open state, and the control unit 312 sends an instruction to the third power supply circuit 340 to output 0 (V). As a result, in the case of operation mode 4, a current flows from the first power supply circuit 140 to the quasi-electrostatic field generating unit 14R and then to the third power supply circuit 340.

[0052] When the operating mode is operating mode 5, the terminal control unit 112 sends an instruction to the first power supply circuit 140 to output 0 (V), the control unit 212 sends an instruction to the second power supply circuit 240 to put it in an open state, and the control unit 312 sends an instruction to the third power supply circuit 340 to output a predetermined voltage. As a result, in the case of operation mode 5, a current flows from the third power supply circuit 340 to the quasi-electrostatic field generating unit 14R and then to the first power supply circuit 140.

[0053] <Wearable device 1 processing> The processing of the wearable device 1 will be described with reference to FIG.

[0054] The terminal control unit 112 acquires external environment information from the sensing device 500 (step S110).

[0055] The terminal control unit 112 determines the operation mode based on the external environment information acquired in step S110 (step S120).

[0056] The terminal control unit 112 executes control to vibrate either the bone conduction unit 13L or the bone conduction unit 13R according to the detected vehicle position (step S130).

[0057] The terminal control unit 112 controls the direction of the current flowing through the quasi-electrostatic field generating unit 14 in accordance with the operation mode determined in step S120 (step S140), and ends the process.

[0058] <Actions and Effects> As described above, the wearable terminal 1 of this embodiment includes a connecting band 11 that extends in a curved shape so as to wrap around the side of the head, a protruding frame 12 formed on both sides of the longitudinal direction of the connecting band and protruding toward the side of the head in front of the user's ear, a bone conduction unit 13 provided on the inner surface of the lower part of the protruding frame 12 and in close contact with the side of the user's head to transmit sound, a quasi-electrostatic field generating unit 14 arranged in a strip shape on the connecting band 11, a first control unit 100 provided in front of the user's right ear, a second control unit 200 provided in front of the user's left ear, a third control unit 300 provided at the back of the user's head, an external environment information acquisition unit 111 that acquires external environment information, and a terminal control unit 112 that controls the operating state of the first control unit 100 to the third control unit 300 based on the acquired external environment information. When the wearable device 1 detects an approaching vehicle based on the external environment information, it controls the direction of the current flowing through the quasi-electrostatic field generating unit 14 to provide a stimulus to the user. That is, when the wearable terminal 1A detects an approaching vehicle, it changes the generation of the quasi-electrostatic field in accordance with the external environment information, and notifies the user of the traveling direction of the approaching vehicle. As a result, when the wearable device 1 detects an approaching vehicle, the user can be made aware of the presence of the approaching vehicle by the stimulation caused by the change in the quasi-electrostatic field.

[0059] The terminal control unit 112 of the wearable terminal 1 in this embodiment detects the possibility of a danger occurring based on the acquired external environment information, and controls the operating states of the first control unit 100 to the third control unit 300 to change the generation of the quasi-electrostatic field in the direction of the danger. The terminal control unit 112 acquires external environment information about the surroundings of the vehicle, and detects the position and traveling direction of an approaching vehicle based on the acquired information. The terminal control unit 112 controls the output of the first power supply circuit 140, the second power supply circuit 240, and the third power supply circuit 340 so that the direction of the current flowing to the quasi-electrostatic field generating unit 14 is the same as the traveling direction of the approaching vehicle. The terminal control unit 112 controls the traveling direction of the approaching vehicle and the direction of the current flowing in the quasi-electrostatic field generating unit 14 to be the same, thereby transmitting the position (right or left) and traveling direction (from which direction the vehicle is approaching) of the approaching vehicle to the user. This enables the wearable device 1 to alert the user to an approaching vehicle by the stimulation caused by the change in the quasi-electrostatic field.

[0060] The external environment information acquisition unit 111 of the wearable device 1 according to this embodiment acquires external environment information from a device that senses surrounding environment information via short-range wireless communication. That is, the wearable device 1 can detect the position of an approaching vehicle and the traveling direction of the vehicle with high accuracy based on the output of a sensor such as a camera or millimeter wave radar installed in the vehicle. Since the wearable device 1 acquires external environment information through short-range wireless communication, if the vehicle is equipped with the sensing device 500, the wearable device 1 can easily acquire the external environment information. This allows the wearable device 1 to notify the user of an approaching vehicle even if the vehicle being driven has changed.

[0061] <Second embodiment> The danger warning system 10 according to this embodiment will be described with reference to Figs. In addition, since the components having the same reference numerals as those in the first embodiment have the same functions, detailed description thereof will be omitted.

[0062] <Configuration of danger warning system 10> As shown in FIG. 7, the danger notification system 10 includes a sensing device 500, a danger detection device 600, and a wearable terminal 1A.

[0063] In this embodiment, the danger detection device 600 is, for example, a device installed in a vehicle, and detects that a danger is approaching the vehicle. In this embodiment, for example, when the danger detection device 600 detects that a danger is approaching the vehicle, the danger detection device 600 transmits information indicating the approaching danger to the wearable terminal 1A, which will be described later. The configuration of the danger detection device 600 will be described later.

[0064] In this embodiment, the wearable terminal 1A stops the operation of the quasi-electrostatic field generating unit 14 and outputs an alarm from the bone conduction unit 13 when, for example, the vehicle being driven is in danger. The configuration of the wearable terminal 1A will be described later.

[0065] <Configuration of danger detection device 600> The danger detection device 600 according to this embodiment will be described with reference to FIG.

[0066] As shown in FIG. 8, the danger detection device 600 includes a communication unit 610 and a danger detection unit 620.

[0067] The communication unit 610 is, for example, a short-range wireless communication unit such as Bluetooth (registered trademark), and communicates with the wearable terminal 1A.

[0068] In this embodiment, the danger detection unit 620 detects whether or not a danger is approaching the vehicle based on the output of sensors such as a camera and a millimeter wave radar installed in the vehicle. In this embodiment, the danger detection unit 620 determines that the vehicle is in danger when it determines that the vehicle will come into contact with another vehicle if the vehicle driving operation (steering, braking, or accelerator operation) is not controlled. In this embodiment, when the danger detection unit 620 detects a vehicle in a position that is difficult to see from the driver's seat (e.g., a blind spot) and detects that the user has operated the turn signal in a direction approaching the vehicle, the danger detection unit 620 transmits information about the approaching danger to the wearable terminal 1A via the communication unit 610.

[0069] <Wearable device 1A configuration> The configuration of the wearable terminal 1A will be described with reference to FIG.

[0070] As shown in FIG. 9, the wearable terminal 1A includes a bone conduction unit 13, a first control unit 100A, a second control unit 200, a third control unit 300, and a quasi-electrostatic field generating unit 14.

[0071] <Configuration of the first control unit 100A> The configuration of the first control unit 100A will be described with reference to FIG.

[0072] The first control unit 100A includes a processor 110A, a memory 120, a communication unit 130, and a first power supply circuit 140.

[0073] In this embodiment, the processor 110A controls, for example, the vibration of the bone conduction unit 13 and the direction of the current flowing in the quasi-electrostatic field generating unit 14. The configuration of the processor 110 will be described later.

[0074] <Configuration of the Processor 110A> As shown in FIG. 10, the processor 110A includes an external environment information acquisition unit 111 and a terminal control unit 112A. Each unit of the processor 110A and the memory 120 transmit and receive various information via a bus line BL1.

[0075] The terminal control unit 112A performs overall control of the first control unit 100A in accordance with a control program stored in the memory 120. In this embodiment, the terminal control unit 112A vibrates the bone conduction unit 13 based on the external environment information received from the external environment information acquisition unit 111, for example. In this embodiment, for example, when it is determined that an approaching vehicle is traveling on the right side, the terminal control unit 112 vibrates the bone conduction unit 13R at 10 MHz. In this embodiment, for example, when the terminal control unit 112 determines that the approaching vehicle is traveling on the left side, it transmits an instruction to vibrate the bone conduction unit 13L to the second control unit 200 described later. In this embodiment, for example, when an approaching vehicle cannot be detected, the terminal control unit 112A stops the vibration of the bone conduction unit 13R. In this embodiment, for example, when the terminal control unit 112A cannot detect an approaching vehicle, it transmits an instruction to the second control unit 200 to stop vibration of the bone conduction unit 13L.

[0076] In this embodiment, the terminal control unit 112A stops the operation of the quasi-electrostatic field generating unit 14 when, for example, the host vehicle is in danger. In this embodiment, for example, when the terminal control unit 112A receives information from the danger detection device 600 indicating that danger is approaching, it performs control to stop the operation of the quasi-electrostatic field generating unit 14. In this embodiment, for example, when the terminal control unit 112A stops the operation of the quasi-electrostatic field generating unit 14, it determines the operation mode of the quasi-electrostatic field generating unit 14 to operation mode 1, and transmits information regarding the determined operation mode to the second control unit 200 and the third control unit 300. In this embodiment, for example, when the terminal control unit 112A receives information from the danger detection device 600 that a danger is approaching, the terminal control unit 112A performs control to cause the bone conduction unit 13 to output an alarm. In this embodiment, for example, the terminal control unit 112A controls the bone conduction unit 13R to output an alarm, and at the same time transmits an instruction to the second control unit 200 to output an alarm.

[0077] <Processing of wearable device 1A> The processing of the wearable terminal 1A will be described with reference to FIG.

[0078] The terminal control unit 112A acquires external environment information from the sensing device 500 (step S110).

[0079] The terminal control unit 112A determines the operation mode based on the external environment information acquired in step S110 (step S120).

[0080] The terminal control unit 112A executes control to vibrate either the bone conduction unit 13L or the bone conduction unit 13R according to the detected vehicle position (step S130).

[0081] The terminal control unit 112A controls the direction of the current flowing through the quasi-electrostatic field generating unit 14 in accordance with the operation mode determined in step S120 (step S140).

[0082] The terminal control unit 112A determines whether or not information indicating that danger is approaching has been received from the danger detection device 600 (step S210). When the terminal control unit 112A determines that it has not received information from the danger detection device 600 indicating that danger is approaching ("NO" in step S210), it returns the process to step S110 and continues the process. When the terminal control unit 112A determines that information indicating an imminent danger has been received from the danger detection device 600 ("YES" in step S210), it shifts the process to step S220.

[0083] The terminal control unit 112A executes control to output an alarm from the bone conduction unit 13 (step S220).

[0084] The terminal control unit 112A executes control to stop the operation of the quasi-electrostatic field generating unit 14 (step S230), and ends the process.

[0085] <Actions and Effects> As described above, the danger warning system 10 according to this embodiment includes the wearable terminal 1A and the danger detection device 600 that detects that a danger is approaching the vehicle. When the wearable terminal 1A is in danger, the terminal control unit 112A stops the operation of the quasi-electrostatic field generating unit 14 and controls the bone conduction unit 13 to output an alarm. In other words, when the risk of contact with a vehicle or the like becomes extremely high, the danger warning system 10 stops the operation of the quasi-electrostatic field generating unit 14 and causes the bone conduction unit 13 to output an alarm. This enables the danger alarm system 10 to notify the user of the approaching danger. The wearable terminal 1A is a bone conduction earphone. That is, even when the user wears the wearable terminal 1A, the user's ears are not blocked, so the user can recognize sounds occurring inside and outside the vehicle. As a result, even if an alarm is output from the bone conduction unit 13 of the wearable terminal 1, the user can perform driving operations to avoid contact based on information from his or her eyes and ears.

[0086] <Variation 1> The wearable terminal 1 according to the first embodiment described above is a terminal in which the bone conduction unit 13 is placed in close contact with the front of the ear to transmit sound to the user. However, for example, the bone conduction unit 13 may be placed in a position behind the ear so that it is placed in close contact with the mastoid process to transmit sound to the user.

[0087] <Variation 2> The wearable device 1 described above alerts the user to the presence of an approaching vehicle while driving a vehicle, but it may also be configured to detect the positions of people and vehicles walking around the user while walking, for example, and alert the user to the approach of people or vehicles. For example, a mobile terminal carried by a user uses Bluetooth (registered trademark) communication to detect other mobile terminals present in the user's vicinity, and detects the position and direction of movement of the mobile terminals. That is, the wearable device 1 acquires external environment information from a portable device carried by the user, and generates a quasi-electrostatic field in accordance with the direction of movement of the surrounding portable devices. This allows the user to sense the approach of a vehicle that cannot be seen from where the user is walking.

[0088] The wearable terminal 1 of the present invention can be realized by recording the processing of the terminal control unit 112, control unit 212, and control unit 312 of the wearable terminal 1 described above on a recording medium readable by a computer system, reading the program recorded on this recording medium into memory, and executing it. The computer system referred to here includes the OS and hardware such as peripheral devices.

[0089] If the above computer system utilizes a WWW (World Wide Web) system, it also includes the homepage providing environment (or display environment). The above-mentioned program may be transmitted from a computer system in which the program is stored in a storage device or the like to another computer system via a transmission medium, or by a transmission wave in the transmission medium. The transmission medium for transmitting the above-mentioned program refers to a medium having a function for transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.

[0090] The above program may be for realizing a part of the above-mentioned functions. The above program may be a so-called differential file (differential program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
