The notification device according to one aspect of the embodiment includes an acquisition unit that acquires a measurement value related to the air condition, a distance measurement unit that measures the distance to a person, and a first measurement value acquired by the acquisition unit. When the measured value is acquired by the threshold storage unit that stores the threshold value and the acquisition unit, and the measured value exceeds the first threshold value stored by the threshold storage unit, the measured value is the first. It is provided with an output unit that outputs an output indicating that the threshold value is exceeded, and the output unit is characterized in that the output mode is changed according to the distance measured by the distance measuring unit in the output.

The notification device notifies the person in an output mode according to the distance to the person around the person.

Therefore, according to the above notification device, the possibility that the person who receives the notification feels the notification annoying can be reduced as compared with the conventional case.

Further, a distance threshold storage unit for storing the distance threshold of the distance measured by the distance measuring unit is provided, and the output unit stores the distance measured by the distance measuring unit by the distance threshold storage unit. If it is smaller than the distance threshold value, the output is performed by light emission, and if the distance measured by the distance measuring unit is not smaller than the distance threshold value stored by the distance threshold storage unit, the sounding is performed. It may output.

As a result, even when the person to be notified is located at a place farther than the distance threshold value, it is possible to reduce the possibility that the person cannot recognize the notification due to overlooking the light emission.

Further, when the distance measured by the distance measuring unit is smaller than the distance threshold stored by the distance threshold storage unit, the output unit increases the brightness, the amount of fluctuation of the brightness, or the brightness as the distance increases. When the light emission is performed so as to increase the amount of fluctuation of the wavelength and the distance measured by the distance measuring unit is not smaller than the distance threshold stored by the distance threshold storage unit, the larger the distance, the more. The sound may be performed so as to increase the volume, the amount of fluctuation of the volume, or the amount of fluctuation of the pitch.

As a result, the notification device can perform notification with a larger amount of stimulation as the distance to the person around it increases.

Further, the threshold storage unit further stores a second threshold value larger than the first threshold value, and the output unit has a measurement value acquired by the acquisition unit larger than (1) the first threshold value. When the output is smaller than the second threshold value, and (2) the measured value acquired by the acquisition unit is larger than the second threshold value, the output is higher than the first threshold value. It is also possible to output in a mode different from the output performed when the output is large and smaller than the second threshold value.

As a result, when the person who receives the notification receives the notification, (1) the measured value is larger than the first threshold value and smaller than the second threshold value, and (2) the measured value is larger than the second threshold value. It becomes possible to distinguish the large case from the large case relatively easily.

Further, the reception unit is further provided with a reception unit that receives an operation by the user, and when the reception unit receives an operation to update the first threshold value, the reception unit is stored in the threshold value storage unit in response to the operation. When the operation of updating the first threshold value and updating the second threshold value is accepted, the second threshold value stored in the threshold value storage unit may be updated in response to the operation.

As a result, the user who uses this notification device can update the first threshold value and the second threshold value relatively easily.

Further, a sensor for outputting a measured value related to the state of air may be provided, and the acquisition unit may perform the acquisition by acquiring the measured value output from the sensor.

As a result, the notification device can acquire the measured value in its own device without having the external device output the measured value.

Further, the acquisition unit includes a communication unit that wirelessly communicates with the external device, and even if the acquisition unit performs the acquisition by receiving the measured value related to the air condition transmitted from the external device by the communication unit. Good.

As a result, the notification device can acquire the measured value transmitted from the external device without outputting the measured value in the own device.

Further, the measured value related to the state of air may be a value obtained by measuring the amount of fine particles contained in the air.

As a result, this notification device can notify the concentration of fine particles contained in the air.

Further, the measured value related to the state of air may be a value obtained by measuring the amount of a predetermined gas contained in the air.

As a result, the notification device can notify the amount of a predetermined gas contained in the air.

Further, the measured value related to the state of air may be a value obtained by measuring the temperature of air.

This allows the notification device to notify about the temperature of the air.

The luminaire according to one aspect of the embodiment is characterized by including the above notification device.

The luminaire notifies the person in an output mode according to the distance to the person around the luminaire.

Therefore, according to the above-mentioned lighting equipment, the possibility that the person receiving the notification may find the notification annoying can be reduced as compared with the conventional case.

[1-1. Constitution]
FIG. 1 is a block diagram showing a configuration of the notification device 1 according to the embodiment.

As shown in the figure, the notification device 1 includes an acquisition unit 11, a distance measuring unit 12, a threshold storage unit 13, an output unit 14, a distance threshold storage unit 15, a sensor 16, and a reception unit 17. Consists of including.

The sensor 16 outputs a measured value related to the state of air. Here, the sensor 16 will be described as an air quality sensor that measures and outputs the concentration of PM2.5, which is fine particles in the air.

The acquisition unit 11 acquires the measured value related to the air condition. More specifically, the acquisition unit 11 acquires the concentration of PM2.5, which is a measured value output from the sensor 16.

As an example, the acquisition unit 11 is realized by executing a program stored in a memory (not shown) constituting the notification device 1 by a microprocessor (not shown) constituting the notification device 1.

The distance measuring unit 12 measures the distance to a person. More specifically, the distance measuring unit 12 includes a distance measuring module (for example, an infrared distance measuring module that measures a distance using infrared rays) for measuring the distance to a person in the vicinity, and uses the distance measuring module. And measure the distance to the person.

When the distance measuring unit 12 attempts to measure the distance to a person and cannot measure the distance to the person, the distance measuring unit 12 determines that the person does not exist in the range that can be measured, and determines that the person does not exist in the range that can be measured. The maximum value that can be measured (for example, 10 m) is output.

As an example, in the distance measuring unit 12, a microprocessor (not shown) constituting the notification device 1 executes a program including the distance measuring module and stored in a memory (not shown) constituting the notification device 1. Then, it is realized by controlling the ranging module.

FIG. 2 is a perspective view schematically showing how the distance measuring unit 12 measures the distance x to a person around the notification device 1.

The threshold value storage unit 13 stores the first threshold value of the measured value acquired by the acquisition unit 11. Further, the threshold value storage unit 13 stores a second threshold value larger than the first threshold value.

As an example, the threshold storage unit 13 is realized by executing a program stored in a memory (not shown) constituting the notification device 1 by a microprocessor (not shown) constituting the notification device 1.

Here, for example, it is assumed that 35 μg / cm ³ (PM2.5 concentration) is stored as the first threshold value and 70 μg / cm ³ (PM2.5 concentration) is stored as the second threshold value.

The distance threshold storage unit 15 stores the distance threshold of the distance measured by the distance measuring unit 12. As an example, the distance threshold storage unit 15 is realized by executing a program stored in a memory (not shown) constituting the notification device 1 by a microprocessor (not shown) constituting the notification device 1. ..

Here, for example, it is assumed that 5 m (distance to a person) is stored as a distance threshold value.

The reception unit 17 accepts operations by the user. Then, when the reception unit 17 receives an operation to update the first threshold value, the reception unit 17 updates the first threshold value stored in the threshold value storage unit 13 in response to the operation. Further, when the reception unit 17 receives an operation to update the second threshold value, the reception unit 17 updates the second threshold value stored in the threshold value storage unit 13 in response to the operation. Further, when the reception unit 17 receives an operation to update the distance threshold value, the reception unit 17 updates the distance threshold value stored in the distance threshold value storage unit 15 in response to the operation.

As an example, in the reception unit 17, a microprocessor (not shown) constituting the notification device 1 executes a program stored in a memory (not shown) including the touch panel and constitutes the notification device 1. It is realized by controlling the touch panel.

When the measured value is acquired by the acquisition unit 11, the output unit 14 indicates that the measured value exceeds the first threshold value when the measured value exceeds the first threshold value stored by the threshold storage unit 13. Is output.

FIG. 3 is a block diagram showing the configuration of the output unit 14.

As shown in the figure, the output unit 14 includes a control unit 21, an LED (Light Emitting Diode) 22, and a speaker 23.

The control unit 21 is connected to the acquisition unit 11, the distance measuring unit 12, the threshold storage unit 13, and the distance threshold storage unit 15, and controls the LED 22 and the speaker 23.

When the distance measured by the distance measuring unit 12 is smaller than the distance threshold stored by the distance threshold storage unit 15, the control unit 21 controls the LED 22 to output light to the output unit 14. Let me. More specifically, when the distance measured by the distance measuring unit 12 is smaller than the distance threshold stored by the distance threshold storage unit 15, the larger the distance, the more the brightness, the amount of fluctuation of the brightness, or the wavelength. The light emission of the LED 22 is controlled so that the amount of fluctuation of the LED 22 increases.

Increasing the brightness as the distance increases means that the brightness increases linearly (linearly) as the distance increases, or increases in a step-like manner (step function) as the distance increases. Say that. When the LED 22 is not lit in the initial state (the lighting state of the LED 22 immediately before the measured value acquired by the acquisition unit 11 becomes larger than the first threshold value), the brightness 0 is set as the reference brightness and is predetermined. The above control is performed using colored light (for example, white light). Here, the reference brightness refers to the brightness when the LED 22 is turned on when the distance measured by the distance measuring unit 12 is 0. When the LED 22 is lit in the initial state, the above control is performed using the light in the lit state with the brightness in the lit state as the reference brightness.

The increase in the amount of brightness fluctuation as the distance increases means that the amount of brightness fluctuation increases linearly as the distance increases, or the amount of brightness fluctuation increases stepwise as the distance increases. To say. When the LED 22 is not lit in the initial state, the above control is performed using light (for example, white color) whose brightness and color are determined in advance as reference light. Here, the reference light refers to the light when the LED 22 is turned on when the distance measured by the distance measuring unit 12 is 0. When the LED 22 is lit in the initial state, the control is performed using the light of the brightness and the color in the lit state as the reference light.

The fact that the amount of wavelength fluctuation increases as the distance increases means that the amount of wavelength fluctuation increases linearly as the distance increases, or the amount of wavelength fluctuation increases stepwise as the distance increases. To say. When the LED 22 is not lit in the initial state, the above control is performed using light whose brightness and color are determined in advance (for example, green monochromatic light) as reference light. When the LED 22 is lit in the initial state, the control is performed using the light of the brightness and the color in the lit state as the reference light.

FIG. 4 shows the distance measured by the distance measuring unit 12 and the amount of luminance, luminance fluctuation, or wavelength fluctuation in the light emission of the LED 22 (hereinafter, these amounts are also referred to as “stimulation amount”). It is a figure which shows the relationship. Here, for example, when the distance is smaller than the distance threshold value of 5 m, the stimulus amount P1 is proportional to the distance by the slope a, and when the distance is larger than the distance threshold value of 5 m, the stimulus amount P1 is 0. It has become.

Further, when the distance measured by the distance measuring unit 12 is not smaller than the distance threshold stored by the distance threshold storage unit 15, the control unit 21 controls the speaker 23 and sounds to the output unit 14. Output by. More specifically, when the distance measured by the distance measuring unit 12 is not smaller than the distance threshold stored by the distance threshold storage unit 15, the larger the distance, the more the volume, the amount of fluctuation of the volume, or The sound generation of the speaker 23 is controlled so that the amount of pitch fluctuation increases.

The increase in volume as the distance increases means that the volume is increased linearly as the distance increases, or the volume is increased stepwise as the distance increases. When the speaker 23 is not producing sound in the initial state, the above control is performed using a predetermined sound with the volume 0 as the reference volume. Here, the reference volume refers to the volume at which the speaker 23 is sounded when the distance measured by the distance measuring unit 12 is 0. When the speaker 23 is sounding in the initial state, the volume in the sounding state is used as a reference volume, and the sound in the sounding state is used for the above control.

The larger the distance, the greater the amount of fluctuation in volume means that the amount of fluctuation in volume increases linearly as the distance increases, or the amount of fluctuation in volume increases stepwise as the distance increases. To say. If the speaker 23 is not producing sound in the initial state, the above control is performed using a sound whose volume and pitch are determined in advance as a reference sound. Here, the reference sound refers to a sound when the speaker 23 is sounded when the distance measured by the distance measuring unit 12 is 0. When the speaker 23 is sounding in the initial state, the above control is performed using the sound of the volume and the pitch in the sounding state as a reference sound.

The increase in the amount of pitch fluctuation as the distance increases means that the amount of pitch fluctuation increases linearly as the distance increases, or the amount of pitch fluctuation increases in a stepwise manner as the distance increases. To say. If the speaker 23 is not producing sound in the initial state, the above control is performed using a sound whose volume and pitch are determined in advance as a reference sound. When the speaker 23 is sounding in the initial state, the above control is performed using the sound of the volume and the pitch in the sounding state as a reference sound.

FIG. 5 shows the distance measured by the distance measuring unit 12 and the volume, volume fluctuation amount, or pitch fluctuation amount in the sound of the speaker 23 (hereinafter, these amounts are also referred to as “stimulation amount”). It is a figure which shows the relationship of. Here, for example, when the distance is smaller than the distance threshold value of 5 m, the stimulus amount P2 becomes 0, and when the distance is larger than the distance threshold value of 5 m, the stimulus amount P2 is proportional to the distance by the inclination a. doing.

Further, the control unit 21 controls the speaker 23 and the LED 22, and the output unit 14 has different modes depending on whether the measured value acquired by the acquisition unit 11 is smaller or larger than the second threshold value. , Light emission or pronunciation. That is, the output unit 14 outputs the above-described embodiment when the measured value acquired by the acquisition unit 11 is larger than the first threshold value and smaller than the second threshold value. On the other hand, the output unit 14 outputs a mode different from the above-described mode when the measured value acquired by the acquisition unit 11 is larger than the second threshold value. Here, the output of this different aspect uses, for example, the LED 22 to emit a predetermined white light at its maximum brightness, and the speaker 23 uses a speaker 23 to emit a predetermined sound at its maximum volume. Described as an output.

As an example, the control unit 21 is realized by executing a program stored in a memory (not shown) constituting the notification device 1 by a microprocessor (not shown) constituting the notification device 1.

The operation performed by the notification device 1 having the above configuration will be described below with reference to the drawings.

[1-2. motion]
The notification device 1 performs the first notification process as its characteristic operation.

This first notification process is a process of acquiring a measured value of the concentration of fine particles contained in the air, and when the measured value of the concentration of the acquired fine particles exceeds a predetermined threshold value, notifies to that effect.

FIG. 6 is a flowchart of the first notification process.

This first notification process is started when the reception unit 17 accepts a predetermined operation to start the first notification process, which is performed by the user of the notification device 1.

When the first notification process is started, the sensor 16 measures and outputs the concentration (air quality) of PM2.5 in the air (step S10). After that, the sensor 16 measures and outputs the concentration of PM2.5 in the air every time a predetermined time (for example, 1 minute) elapses.

When the concentration of PM2.5 is measured, the acquisition unit 11 acquires the concentration of PM2.5 which is a measured value output from the sensor 16 (step S20).

When the measured value of PM2.5 concentration is acquired, the output unit 14 determines whether or not the acquired PM2.5 concentration is larger than the first threshold value of 35 μg / cm ³ stored by the threshold value storage unit. (Step S30).

When a positive determination is made in the process of step S30 (step S30: Yes), the output unit 14 has a second threshold value of 70 μg / cm in which the acquired concentration of PM2.5 is stored by the threshold value storage unit. Check whether it is larger than ³ (step S40).

When a negative determination is made in the process of step S40 (step S40: No), the distance measuring unit 12 measures the distance to a person in the vicinity (step S50).

When the distance to the person is measured, the output unit 14 examines whether or not the measured distance is smaller than the distance threshold value of 5 m stored by the distance threshold value storage unit 15 (step S60).

When a positive determination is made in the process of step S60 (step S60: Yes), the output unit 14 emits light according to the measured distance using the LED 22 (step S70). That is, the output unit 14 emits light so that the brightness, the amount of fluctuation of the brightness, or the amount of fluctuation of the wavelength increases as the measured distance increases according to the measured distance.

If a positive determination is not made in the process of step S60 (step S60: No), the output unit 14 uses the speaker 23 to sound according to the measured distance (step S80). That is, the output unit 14 pronounces the volume, the amount of fluctuation of the volume, or the amount of fluctuation of the pitch increases as the measured distance increases according to the measured distance.

When a positive determination is made in the process of step S40 (step S40: Yes), the output unit 14 emits a predetermined white light with the maximum brightness by using the LED 22 and the speaker 23, and the maximum volume. Produces a predetermined sound with (step S90).

When a negative determination is made in the process of step S30 (step S30: No), when the process of step S70 is completed, when the process of step S80 is completed, and when the process of step S90 is completed. , Proceed to the process of step S100. That is, the acquisition unit 11 determines whether or not a predetermined time has elapsed since the measurement value was output from the sensor 16 last time (step S100).

When the predetermined time elapses (the process of step S100: No is repeated and then the process of step S100: Yes is performed), the notification device 1 proceeds to the process of step S10 and repeats the processes after step S10.

[1-3. Effect, etc.]
When the measured value exceeds the first threshold value, the notification device 1 notifies the person in an output mode according to the distance to the surrounding person. Therefore, according to the notification device 1, the possibility that the person who receives the notification feels the notification annoying can be reduced as compared with the conventional case.

Further, when the distance to a person in the vicinity becomes larger than the distance threshold value, the notification device 1 performs notification by sound instead of the notification by light emission when the distance is smaller than the distance threshold value. Therefore, even when the person to be notified is located at a place farther than the distance threshold value, it is possible to reduce the possibility that the notification is not recognized because the person overlooks the light emission.

In particular, when the notification device 1 is installed in a room and the person to be notified is outside the room (that is, when the person is far from the distance threshold value), the notification by pronunciation emits light. It is more effective than the notification by.

(Modification example)
Here, as one aspect of the present invention, a notification device in a modified example in which a part of the configuration is changed from the notification device 1 in the embodiment will be described.

The notification device 1 in the embodiment was an example of a configuration in which a sensor 16 for measuring a measured value related to an air condition is built-in. On the other hand, the notification device in the modified example is an example of a configuration in which a sensor for measuring a measured value related to the air condition is not built-in.

Hereinafter, the details of this notification device will be described with reference to the drawings, focusing on the differences from the notification device 1 in the embodiment.

[2-1. Constitution]
FIG. 7 is a block diagram showing the configuration of the notification device 2 in the modified example and the configuration of the sensor device 3 which is an external device of the notification device 2.

As shown in the figure, the notification device 2 is changed so that the sensor 16 is deleted from the notification device 1 in the embodiment and the acquisition unit 11 becomes the acquisition unit 111. The sensor device 3 includes the deleted sensor 16 and the communication unit 113.

The communication unit 113 is wiredly connected to the sensor 16 and wirelessly communicates with the communication unit 112 (described later) included in the acquisition unit 111 (described later) of the notification device 2.

As an example, the communication unit 113 includes a wireless communication device, and a microprocessor (not shown) constituting the sensor device 3 executes a program stored in a memory (not shown) constituting the sensor device 3. , It is realized by controlling the wireless communication device.

The acquisition unit 111 includes a communication unit 112.

The communication unit 112 wirelessly communicates with the communication unit 113. As an example, the communication unit 112 includes a wireless communication device, and a microprocessor (not shown) constituting the notification device 2 executes a program stored in a memory (not shown) constituting the notification device 2. , It is realized by controlling the wireless communication device.

Then, the acquisition unit 111 acquires the measured value related to the air state by receiving the measured value related to the air state transmitted from the communication unit 113 of the sensor device 3 by the communication unit 112.

The operation performed by the notification device 2 having the above configuration will be described below with reference to the drawings.

[2-2. motion]
As a characteristic operation thereof, the notification device 2 performs a second notification process in which a part of the first notification process in the embodiment is changed in cooperation with the sensor device 3.

FIG. 8 is a flowchart of the second notification process.

As shown in the figure, in the second notification process, the process of steps S10 to S20 is deleted from the first notification process in the embodiment, and the process of steps S210 to S240 is added instead. It has become. Therefore, here, the processing of steps S210 to S240 will be mainly described.

This second notification process is started when the reception unit 17 accepts a predetermined operation to start the second notification process, which is performed by the user of the notification device 2.

When the second notification process is started, the acquisition unit 111 uses wireless communication to transmit a start signal indicating that the second notification process has been started to the communication unit 113 (step S210).

When the start signal is transmitted, the communication unit 113 receives the start signal. Then, the sensor 16 connected to the communication unit 113 measures and outputs the concentration of PM2.5 in the air (step S220). After that, the sensor 16 measures and outputs the concentration of PM2.5 in the air every time a predetermined time (for example, 1 minute) elapses.

When the concentration of PM2.5 is output, the communication unit 113 transmits the output measured value to the acquisition unit 111 by using wireless communication (step S230).

When the measured value is transmitted, the acquisition unit 111 acquires the concentration of PM2.5, which is the measured value measured by the sensor 16, by receiving the transmitted measured value (step S240).

When the process of step S240 is completed, the notification device 2 proceeds to the process of step S30 and executes the processes after step S30. Then, in the process of step S100, when a predetermined time elapses (step S100: Yes), the sensor device 3 proceeds to the process of step S220 and repeats the processes of step S220 and subsequent steps.

[2-3. Effect, etc.]
The notification device 2 uses wireless communication to acquire a measured value measured by a sensor device 3 arranged at a physically distant place. Therefore, according to this notification device 2, while the notification device 2 is placed in a place different from the place where the measured value needs to be measured, the notification based on the measured value measured in the place where the measured value needs to be measured is sent. You will be able to do it.

FIG. 9 is a perspective view schematically showing an example of a situation in which the notification device 2 and the sensor device 3 are actually used.

In the figure, the notification device 2 is arranged on a desk provided near the center of the room, and the sensor device 3 is arranged near the bay window of the room. In this way, while the notification device 2 is placed on the desk near the place where people who use the room are often used, the sensor device 3 is placed near the bay window where it is necessary to monitor the concentration of PM2.5. Operations such as arranging are possible.

Further, an example of a configuration in which the notification device 2 and the sensor device 3 are built in different devices can be considered.

FIG. 10 is a block diagram showing the structure of the lighting fixture 4 incorporating the notification device 2 and the structure of the air purifier 5 incorporating the sensor device 3.

For example, with such a configuration, the LED 22 of the notification device 2 is also used as the light emitter of the lighting fixture 4, and the sensor 16 of the sensor device 3 is also used as the air quality sensor of the air purifier 5. Can be used.

However, the technique in the present disclosure is not limited to these, and can be applied to embodiments in which changes, replacements, additions, omissions, etc. are made as appropriate.

(1) In the embodiment, the sensor 16 has been described as measuring the concentration of PM2.5 which is a fine particle in the air. However, if the sensor 16 can measure the measured value related to air, it is not necessarily limited to the example of measuring the concentration of PM2.5 which is a fine particle in the air. For example, the sensor 16 may measure the concentration of pollen in the air, or may measure the concentration of a predetermined gas (for example, carbon monoxide, carbon dioxide, city gas, etc.) in the air. The temperature of the air may be measured, or the humidity of the air may be measured.

(2) In the embodiment, the distance measuring unit 12 includes an infrared module, and the infrared module is used to measure the distance to a person. However, the distance measuring unit 12 is not necessarily limited to the example of measuring the distance to the person by using the infrared module as long as the distance to the person can be measured. For example, the distance measuring unit 12 may include a camera and an image recognition device, and the image recognition device may perform image recognition processing on an image captured by the camera to measure the distance to a person. Further, for example, the distance to the person may be measured by measuring the reception power intensity of the beacon wave transmitted from the beacon owned by the target person with a predetermined transmission power intensity.

(3) In the embodiment, when the distance measured by the distance measuring unit 12 is smaller than the distance threshold value, the output unit 14 increases the brightness, the amount of fluctuation of the brightness, or the fluctuation of the wavelength as the distance increases. It was described as controlling the light emission so that the amount increases. However, if the output unit 14 controls the light emission so that the larger the distance measured by the distance measuring unit 12, the greater the amount of stimulation to the person to be notified, it is not necessarily described in the embodiment. It is not necessary to control the light emission as it is. For example, the output unit 14 may control the light emission so that the blinking speed becomes faster as the distance measured by the distance measuring unit 12 increases.

Further, in the embodiment, when the distance measured by the distance measuring unit 12 is not smaller than the distance threshold value, the output unit 14 increases the volume, the amount of fluctuation of the volume, or the fluctuation of the pitch as the distance increases. It was explained as controlling the pronunciation so that the amount increases. However, if the output unit 14 controls the pronunciation so that the larger the distance measured by the distance measuring unit 12, the greater the amount of stimulation to the person to be notified, it is not necessarily described in the embodiment. There is no need to control pronunciation exactly as it is. For example, the output unit 14 may control the pronunciation so that the rhythm of a predetermined music becomes faster as the distance measured by the distance measuring unit 12 increases.

(4) In the embodiment, it has been described that the output unit 14 controls light emission and pronunciation so that the larger the distance measured by the distance measuring unit 12, the larger the amount of stimulation. However, the output unit 14 is not limited to the example of the configuration in which the issuance control and the pronunciation control are performed as described in the above embodiment. As an example, when the distance measured by the distance measuring unit 12 is smaller than the distance threshold value, the output unit 14 controls the light emission so that the amount of stimulation is constant regardless of the distance. Then, when the distance measured by the distance measuring unit 12 is not smaller than the distance threshold value, the output unit 14 controls the pronunciation so that the larger the distance, the larger the stimulus amount. An example is possible. Further, as another example, when the distance measured by the distance measuring unit 12 is smaller than the distance threshold value, the output unit 14 controls light emission so that the larger the distance, the larger the stimulation amount. Do. Then, when the distance measured by the distance measuring unit 12 is not smaller than the distance threshold value, the output unit 14 controls the pronunciation so that the stimulus amount is constant regardless of the distance. Is also possible. Further, as another example, when the distance measured by the distance measuring unit 12 is smaller than the distance threshold value, the output unit 14 controls light emission so that the amount of stimulation is constant regardless of the distance. Do. Then, when the distance measured by the distance measuring unit 12 is not smaller than the distance threshold value, the output unit 14 controls the pronunciation so that the stimulus amount is constant regardless of the distance. Can also be considered.
