<First Embodiment>
<Functional configuration of glasses-type wearable device>
A spectacle-type wearable device 100 according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram illustrating a functional configuration of the glasses-type wearable device 100 according to the present embodiment, and FIG. 2 is a perspective view of the glasses-type wearable device 100 according to the present embodiment.

  As shown in FIG. 1, the glasses-type wearable device 100 includes a sensor unit 110, a color presentation unit 120, a storage unit 130, a communication unit 140, and a control unit 150. Each function of the glasses-type wearable device 100 excluding some sensors (for example, the temperature / humidity sensor 111 in the clothes) is stored in, for example, a box 20 provided in the temple portion 10 of the glasses as shown in FIG. The glasses-type wearable device 100 is connected to the external device 200 as necessary.

  The sensor unit 110 measures an estimation index for estimating the thermal sensation of the user of the glasses-type wearable device 100. The estimation index includes user state information indicating the state of the user of the glasses-type wearable device 100 and environment information indicating the state of the user's surrounding environment, and the control unit 150 estimates the thermal sensation of the user. Use. Note that the estimation index may be only environmental information. In the present embodiment, for example, PMV (Predicted Mean Vote), which is a method for quantifying the average human thermal sensation, is used to estimate the thermal sensation of the user. .

  The user state information includes, for example, the amount of clothes and exercise intensity of the user. The amount of clothes changes in the user's life. For example, if it feels cold, the jacket will be put on, and if it gets hot, the jacket will be removed to make one T-shirt. The amount of clothes is not directly measured, but instead, the sensor unit 110 is provided with a temperature / humidity sensor 111 in the clothes to measure the change in enthalpy in the direction of accumulation or heat dissipation due to the balance of heat in the clothes being out of balance. .

  The in-clothes temperature / humidity sensor 111 measures temperature and humidity in a position where the user's clothes do not touch the skin directly on the back or abdominal chest. The temperature / humidity sensor 111 in the clothes is provided on a plate-like heat insulating material that does not absorb moisture so as to be provided at a position that does not directly touch the skin, and is attached to, for example, a tag of a clothes collar and has a structure. Are connected to each other by wire (proximity wireless communication such as Bluetooth (registered trademark) may be used).

  Heat production by users' metabolism continues to change according to the exercise intensity of human daily activities. Therefore, a pulse sensor 112 is provided in the sensor unit 110 in order to measure exercise intensity. For example, the pulse sensor 112 analyzes the pressure and displacement signal detected from the pulsation of the superficial temporal artery of the temple, and measures the pulse (heart rate). The pulse sensor may be a clip-shaped photoelectric pulse sensor that sandwiches the earlobe. Here, the exercise intensity necessary for calculating the PMV value is calculated by the carbonene method from the pulse rate measured by the pulse sensor 112 and the normal pulse rate, age, and weight stored in the storage unit 130. can do.

  The environmental information includes, for example, temperature, humidity, wind speed, and radiation temperature. The sensor unit 110 includes a temperature sensor 113 that measures ambient temperature, a humidity sensor 114 that measures ambient humidity, a wind speed sensor 115 that measures ambient wind speed, and ambient radiation temperature as sensors for measuring them. A radiant heat sensor 116 for measurement is provided.

  As the temperature sensor 113, for example, a band gap type semiconductor temperature sensor can be used. As the humidity sensor 114, a capacitance type relative humidity sensor can be used. As the wind speed sensor 115, a hot wire wind speed sensor using a thermocouple can be used. As the radiant heat sensor 116, a globe temperature sensor may be used, or an infrared radiant temperature sensor may be used in order to reduce the size.

  The color presentation unit 120 is a display surface arranged in front of the user's field of view, and changes from colorless and transparent to either warm color transparency or cold color transparency according to an instruction from the control unit 150. Here, warm colors are red, orange, yellow, etc., reminiscent of fire and the sun, and cold colors are blue, blue-green, reminiscent of cold things such as snow and ice. Purple etc.

  FIG. 3A shows a view of the color presentation unit 120 from the side. The color presenting unit 120 uses the technique described in Patent Document 5 and includes a cold-colored electrochromic element 310 and a warm-colored electrochromic element 320 formed on a transparent glass substrate or a transparent resin substrate. The sheets are stacked.

  The color presentation unit 120 is provided with a transparent electrode for each of the cold-colored electrochromic element 310 and the warm-colored electrochromic element 320 and can be individually controlled. It can be changed transparently. Since the color presentation unit 120 changes from colorless and transparent to cold-colored transparent or warm-colored transparent, it is possible to present cold-colored and warm-colored colors to the visual information of the user.

  In addition, the color presentation unit 120 can arrange a cold-colored electrochromic element in an arbitrary portion. For example, as shown in FIG. The central part 121 and the peripheral part 122 may be individually controllable by disposing two electrodes on the peripheral part 122 and providing an electrode for each. The same applies to warm color electrochromic elements.

  By arranging the electrochromic element in this way, the color presentation unit 120 is made transparent in the peripheral part 122 as shown in FIG. 3C and transparent in the cold color or warm color, and the central part 121 is colorless and transparent. Can do. Conversely, the central part 121 may be cold-colored or warm-colored and the peripheral part 122 may be colorless and transparent.

  By further arranging a plurality of electrochromic elements in a concentric or matrix form in the central part 121 and the peripheral part 122, and providing an electrode for each of them, the color presentation part 120 can be controlled in a finer gradation. It can also be.

  Note that in the color presentation unit 120, even if gradation is realized by making the color developing layer thickness of the electrochromic element in the portion that wants to be close to transparent thin and making the color developing layer thickness of the electrochromic element in the location that wants to develop the color darker Good.

  The storage unit 130 feels uncomfortable because the user is too hot and feels uncomfortable PMV value (hereinafter referred to as PMVhot value) that is not effective even when a cold color is presented, and feels uncomfortable because it is too cold. An unpleasant PMV value (hereinafter referred to as PMVcold value) for which no effect is obtained even if the color is presented is stored. The PMV value is defined in ISO standard 7730. Normally, the PMVhot value is “+3 (boundary value between hot and too hot)”, and the PMVcold value is “−3 (cold and too cold). Boundary value) ”is set.

  However, there are individual differences in the thermal sensation that is unpleasant because it is too hot or too cold. Therefore, the PMVhot value and the PMVcold value set in advance by the user may be stored in the storage unit 130. For example, a user who is aware that “it is cold” sets the PMVcold value to “−2 (cool)”, and a user who is aware that “it is hot” sets the PMVhot value to “+2 (warm)”. May be set.

  The storage unit 130 also stores information on the user's age, sex, height, weight, and normal pulse rate. The age, sex, height, and weight of the user are acquired from the external device 200 via the communication unit 140 and stored in the storage unit 130. The normal pulse rate is a pulse rate at rest, but the age In the same manner as described above, it may be acquired from the external device 200 via the communication unit 140 and stored in the storage unit 130, or the value calculated by the control unit 150 from the pulse wave measured by the pulse sensor 112 and obtained as the pulse rate. There may be. For example, the average pulse rate measured by the pulse sensor 112 is accumulated by the storage unit 130 every minute, and is accumulated in order to avoid a protruding value, a maximum value, or a minimum value from the accumulated average pulse rate. The average pulse rate on the lower side in the statistical 95% confidence interval is determined from the histogram of average pulse rate per minute. The acquisition of information such as age from the external device 200 can be solved by obtaining it in cooperation with a health management service via the cloud, for example.

  Further, the storage unit 130 accumulates the PMV value calculated by the control unit 150.

  The control unit 150 estimates the thermal sensation of the user based on the estimated index measured by the sensor unit 110, and instructs the color presenting unit 120 on the color according to the estimated thermal sensation. Specifically, the control unit 150 estimates the thermal sensation of the user from the temperature, humidity, wind speed, radiation temperature measured by the sensor unit 110, and the exercise intensity and the amount of clothes calculated from the pulse rate. Of PMV is calculated. Here, it is not necessary to measure the amount of clothes (clo), and it is calculated as each fixed value (for example, 0.6 [clo] in summer and 1.0 [clo] in winter).

  Then, based on the calculated PMV value and the enthalpy change measured by the clothing temperature / humidity sensor 111, the user's thermal sensation is estimated, and a color instruction is given to the color presentation unit 120 according to the estimation result. For example, when the PMVhot value is “+3” and the PMV value is “PMVhot value−1” or more and gradually approaches the PMVhot value, or when the enthalpy in the clothing is increasing, The feeling is presumed to be “hot”, and the color presentation unit 120 is instructed to present a cold-colored transparent color.

  In addition, the control unit 150 compares the calculated PMV value with the PMVhot value and the PMVcold value, and changes in the enthalpy in the clothes, whether it is too hot and uncomfortable or too cold and feels uncomfortable. And instructing color to the color presentation unit 120 according to the estimation result. For example, when it is estimated that the controller 150 is not too hot and unpleasant, and is too hot and uncomfortable, the controller 150 instructs the color presenter 120 to present a cold-colored transparent color. .

  Furthermore, the color presented by the color presentation unit 120 is associated with the thermal sensation of the user, and the user is repeatedly presented with an experience such as “cold color is cool” or “warm color is warm”. In order to strengthen the human psychological reaction that the thermal sensation changes due to the temperature, the control unit 150 performs a stepwise process based on the calculated PMV value, the PMV value stored in the storage unit 130, the PMVhot value, and the PMVcold value. Depending on the result of estimating whether the temperature has changed rapidly or cold, and the thermal sensation of the user estimated based on the calculated PMV value. Give instructions. For example, if the control unit 150 estimates that the user's thermal sensation is not “too cold and uncomfortable” but “cool”, the color presentation unit Instruct 120 to present a cold-colored transparent color.

  In addition, the control unit 150 estimates the heat balance in the clothing due to the clothing state, the thermal insulation performance and heat dissipation performance of the clothing, the heat generation from the human body, and the like from the enthalpy change in the clothing measured by the temperature and humidity sensor 111 in the clothing. Thus, it can also be used for the determination of giving a color instruction to the color presentation unit 120.

  The processing of the control unit 150 described above may be executed by the external device 200 connected via the communication unit 140. Thereby, complicated calculations can be performed, and the capacity of the storage unit 130 can be reduced.

  The control unit 150 instructs the color presentation unit 120 to indicate the color when the user learns that the cold color system is cool and the warm color system is warm depending on the color of the color presentation unit 120. When the color is a cold color, there are two cases: a case where the thermal sensation is lowered, and a case where the color is warm, the thermal sensation is increased to change the thermal sensation of the user. Each case will be specifically described. Here, it is assumed that the user wears the glasses-type wearable device 100 and lives.

  First, a case where the user learns that “cold color is cool” will be described. For example, it is assumed that a user goes out on a hot day and enters an air-conditioned store (indoor temperature 23 ° C.) from an ambient temperature (outside air temperature 26 ° C.). At this time, the control unit 150 of the glasses-type wearable device 100 detects that the PMV value is rapidly decreased stepwise due to a rapid temperature change from 26 ° C. to 23 ° C. At this time, if the PMV value exceeds the PMVcold value stored in the storage unit 130, the control unit 150 gives an instruction to the color presentation unit 120 to present a cool color transparency indicating coolness for about 300 seconds. The color presentation unit 120 is instructed to return to colorless and transparent over about 100 seconds.

  In addition, even when the PMV value suddenly changes stepwise due to changes in the environment such as temperature, humidity, wind speed, and radiant heat, the control unit 150 similarly gives an instruction to present a cold-colored transparency for about 300 seconds. After going to 120, the color presentation unit 120 is instructed to return to colorless and transparent over about 100 seconds. When the PMV value is equal to or less than the PMVcold value, the control unit 150 does not instruct the color presenting unit 120 to present the cold color transparency in order to prevent the user's thermal sensation from being further lowered.

  By doing in this way, every time it moves from a hot summer space to a cool space, the cool color is presented in the color presentation, and when the cool color transparency is presented, the user learns that it is cool. As a result, the human psychological reaction that the thermal sensation changes depending on the color can be strengthened.

  A case will be described in which cold color transparency is presented to the color presentation unit 120 to reduce the thermal sensation of the user. If you spend time in the room on a hot day, the temperature will gradually rise and you will feel hot. At this time, the PMVhot value that exceeds the “PMVhot value-1” that the PMV value feels hot is about to be reached, and the balance of heat balance in the clothing is lost, and the heat and heat stored in the clothing are stored, so the temperature and humidity in the clothing When a change in enthalpy rise appears on the sensor, the control unit 150 instructs the color presentation unit 120 to gradually change from colorless and transparent to cold-colored transparent over about 100 seconds. When the cold color transparency is presented to the color presentation unit 120, the above-described learning that “the cold color system is cool” is recalled to the user, and the thermal sensation of the user can be lowered.

  Next, a case where the user learns that “the warm color system is warm” will be described. For example, it is assumed that a user goes out on a cold day and enters an air-conditioned store (room temperature 20 ° C.) from an ambient temperature (outside air temperature 6 ° C.). At this time, the control unit 150 of the glasses-type wearable device 100 detects that the PMV value is rapidly increased stepwise due to a rapid temperature increase from 6 ° C. to 20 ° C. In this case, when the PMV value is less than the PMVhot value, the control unit 150 gives an instruction to present the warm color system transparency indicating the warmth to the color presenting unit 120 for about 300 seconds, and then is colorless over about 100 seconds. An instruction to return to transparency is given to the color presentation unit 120.

  Also, when the PMV value suddenly increases stepwise in the direction in which humidity, wind speed, radiant heat, and temperature / humidity in the clothes feel warm, the control unit 150 similarly gives an instruction to present warm color transparency for about 300 seconds. After going to the color presentation unit 120, the color presentation unit 120 is instructed to return to colorless and transparent over about 100 seconds. When the PMV value is equal to or higher than the PMVhot value, the control unit 150 does not give an instruction for presenting warm color transparency to the color presentation unit 120 in order to prevent the user from further increasing the thermal sensation.

  By doing so, every time the winter space moves from the cold space to the warm space, the warm color system transparency is presented in the color presentation, and when the warm color system is presented, the user is made to learn that it is warm. As a result, the human psychological reaction that the thermal sensation changes depending on the color can be strengthened.

  A case will be described in which warm color transparency is presented to the color presentation unit 120 to increase the user's thermal sensation. If you spend a day in the room on a cold day, the temperature will gradually drop and you will feel cold. At this time, the PMV value is less than “PMVcold value + 1” which feels that the PMV value is cold, and the balance of heat balance in the clothing is lost, the heat in the clothing is dissipated, and the temperature and humidity in the clothing are dissipated. When a change in enthalpy reduction appears on the sensor, the control unit 150 instructs the color presentation unit 120 to gradually change from colorless and transparent to warm color-based transparency over about 100 seconds. When the warm color system transparency is presented to the color presentation unit 120, the above-described learning that “the warm color system is warm” is recalled to the user, and the warmth and coolness of the user can be raised.

  In addition, when going out of the air-conditioned space (temperature 19 ° C.) in winter (outside air temperature 0 ° C.), the controller 150 of the glasses-type wearable device 100 causes a sudden temperature drop from 19 ° C. to 0 ° C. Although a decrease in the PMV value is detected, in this case, the color presentation unit 120 is not instructed to change the color in order to prevent the thermal sensation from being lowered. Similarly, when going out of an air-conditioned space (temperature: 25 ° C.) in summer (outside air temperature: 30 ° C.), the color presentation unit 120 is not instructed to change the color in order to prevent an increase in thermal sensation.

  As mentioned above, although the example which controls the color presentation part 120 based on the enthalpy change in the clothes measured with the temperature / humidity sensor 111 in the clothes was given, even in the environment which does not use the temperature / humidity sensor 111 in the clothes, only the change tendency of the PMV value Based on this, controlling the color presentation unit 120 is less effective than when using the degree of enthalpy change in the clothes, but it is possible to obtain an effect of changing the thermal sensation of the user. Conversely, the color presentation unit 120 can also be controlled based only on the enthalpy change measured by the in-clothes temperature and humidity sensor 111. Although the effect is less than when using a sensor for measuring changes in environmental information such as temperature, humidity, wind speed, and radiation temperature, it is possible to obtain an effect of changing the thermal sensation of the user.

<Cooling feeling induction process flow>
FIG. 4 is a diagram showing a thermal sensation change inducing process flow in the glasses-type wearable device 100 according to the present embodiment. This process starts in response to the user wearing the glasses-type wearable device 100. Whether or not the user wears it may be determined by the control unit 150 according to whether or not the pulse sensor 112 has detected the pulse rate, or may be determined by the user pressing a start switch, for example. .

  First, in step S <b> 1, the sensor unit 110 measures an estimation index for estimating a user's thermal sensation including only user state information and environment information, or environment information.

  Next, in step S <b> 2, the control unit 150 estimates the thermal sensation of the user based on the estimation index measured in the first step, and instructs the color presentation unit 120 according to the estimated thermal sensation. To do. Step S2 includes a step of calculating the PMV value from the user state information and the environment information measured in step S1, a step of storing the calculated PMV value in the storage unit 130, and the calculated PMV value and the storage unit. Based on the PMV value stored in 130, the result of estimating whether the temperature has suddenly changed to the colder or hotter, and the user estimated based on the calculated PMV value A step of giving a color instruction to the color presentation unit 120 according to the thermal sensation.

  Next, in step S <b> 3, the color presentation unit 120 changes from colorless and transparent to either warm-colored transparent or cold-colored transparent in response to a color instruction from the control unit 150.

  Next, in step S4, the control unit 150 determines whether or not the glasses-type wearable device 100 has been removed. If it is determined that it has been removed (YES), the process ends. If it is determined that it has not been removed (NO), the process returns to step S1. Whether the user has removed it may be determined by the control unit 150 when the pulse sensor 112 can no longer detect the pulse rate, or may be determined by the user pressing a stop switch, for example.

  In this embodiment, the PMV value is used to determine the thermal sensation of the user. However, the thermal sensation index (TSI) proposed in Non-Patent Document 1 is a commonly known standard new effective. Evaluate human comfort such as temperature (SET *), WBGT (wet bulb globe temperature), developed by US National Weather Service (heat index), discomfort index (DI) and working temperature (OT) The controller 150 may determine the thermal sensation by using one or a plurality of indices.

  In this case, the information necessary for calculating each of these indices may be acquired by providing the sensor unit 110 with sensors for measuring them, or may be acquired from the external device 200 via the communication unit 140. May be.

  As described above, according to the present embodiment, when the user becomes hot or cold, the thermal sensation changes depending on the color by changing the color of the lens of the glasses to a warm color system or a cold color system. It is possible to change the thermal sensation for each user using the psychological reaction of human beings.

  In addition, for example, when the user moves to a warm place and the surrounding environment of the user becomes warm, the color of the lens of the glasses is changed to a warm color system. Can learn. In addition, for example, when the user moves to a cool place and the surroundings of the user become cool, the user can learn that it is cool when the cool color system is presented by setting it to the cool color system. . As a result, the human psychological reaction that the thermal sensation changes depending on the color can be strengthened.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIG. Note that the glasses-type wearable device 101 according to the present embodiment corrects the PMVhot value and the PMVcold value stored in the storage unit 131, thereby using the human psychological reaction that the thermal sensation changes depending on the color. The thermal sensation is changed more suitably. In addition, about the component which attaches | subjects the same code | symbol as 1st Embodiment, since it has the same function, the detailed description is abbreviate | omitted.

  As shown in FIG. 5, the glasses-type wearable device 101 includes a sensor unit 110, a color presentation unit 120, a storage unit 131, a communication unit 140, and a control unit 151.

  The storage unit 131 stores the in-clothes temperature / humidity measured by the in-clothes temperature / humidity sensor 111 in the storage unit 131. In addition, the storage unit 131 accumulates the pulse rate measured by the pulse sensor 112 in the storage unit 131.

  The control unit 151 corrects the PMVhot value and the PMVcold value stored in the storage unit 131 with the corrected PMVhot value and the corrected PMVcold value calculated by each method described later. Hereinafter, a method for calculating the corrected PMVhot value and the corrected PMVcold value will be described.

  As a first method, a method of calculating the corrected PMVhot value and the corrected PMVcold value according to the user's hypothermia and basal metabolism will be described.

  It has been reported that the thermal sensation of the user is affected by hypothermia (low metabolism) or large basal metabolism (Non-patent document: Architectural Institute of Japan Hokkaido Branch Research Report No. 84 2011) July “Effects of hypothermia and basal metabolism on thermal sensation” Tomida Tomami et al.).

  The control unit 151 estimates whether the user has a low body temperature or high basal metabolism based on the in-clothing temperature / humidity accumulated in the storage unit 131. Specifically, the control unit 151 determines that the temperature is hypothermic when the user has a lower average clothing temperature than the same age. In this case, since it is easy for the user to feel “cold”, the control unit 151 corrects the PMVcold value in the storage unit 131 by, for example, “+1” the correction PMVcold value. In order to determine whether the average temperature inside the clothes is low, the average temperature inside the clothes for each human gender age may be stored in the storage unit 131 in advance and compared, or via the communication unit 140. Alternatively, an average value of the temperature in clothes of a plurality of same-aged users who are accumulated in the external device 200 may be used.

  On the other hand, the control unit 151 determines that the basal metabolism is high when the user has a higher average clothing temperature than the same age. In this case, since the user can easily feel “hot”, the control unit 151 corrects the PMVhot value of the storage unit 131 by setting the correction PMVhot value to “−1”, for example.

  As a second method, a method of calculating a corrected PMVhot value and a corrected PMVcold value by determining whether the user feels hot or cold according to which of the parasympathetic nerve and the sympathetic nerve is dominant will be described. .

  The control unit 151 considers the fluctuation of the pulse-to-pulse time interval as the heartbeat interval (RRintival) fluctuation from the pulse wave acquired from the pulse sensor 112 and performs frequency analysis, and performs a high frequency component (HF: 0.15-0). .4 Hz) and a low frequency component (LF: 0.05 to 0.15 Hz) (HF / LF) is calculated. Then, the control unit 151 estimates which of the parasympathetic nerve and the sympathetic nerve is dominant. When HF / LF is large, the parasympathetic nerve is active, and when it is low, the sympathetic nerve is active. The normal pulse rate is obtained by the method described in the first embodiment.

  The control unit 151 is used when the parasympathetic nerve is dominant in summer and the enthalpy (denoted here as Hcl) determined from the temperature and humidity in the clothing temperature and humidity sensor 111 increases. Estimate that the person feels hot. This is because parasympathetic nerves that expand peripheral blood vessels and sweat glands work preferentially in preventing an increase in body temperature.

  On the other hand, in winter, the control unit 151 is presumed that the user feels cold when the sympathetic nerve is dominant and the enthalpy (Hcl) determined from the temperature and humidity in the clothes decreases. This is because the sympathetic nerve that narrows the peripheral blood vessels and sweat glands and prevents heat release works preferentially when preventing the body temperature from falling.

  The control unit 151 accumulates the PMV value when it is estimated that the user feels hot or cold in the storage unit 131, and calculates the corrected PMVhot value and the corrected PMVcold value from the accumulated PMV value. The PMV value at this time is preferably in increments of 0.1. For example, among the PMV values accumulated in the storage unit 131, the control unit 151 feels that the most frequent PMV value when it is estimated to be hot from the latest 30-day data is corrected PMVhot value, cold. The most frequent PMV value at the time of estimation is taken as the corrected PMVcold value. And the control part 151 correct | amends the PMVhot value of the memory | storage part 131 with the calculated correction | amendment PMVhot and correction | amendment PMVcold value.

  As a third method, a method of calculating the corrected PMVhot value and the corrected PMVcold value by self-reporting whether the user is hot or cold will be described.

  The sensor unit 110 further includes a touch sensor (not shown). When the user feels uncomfortable because it is too hot or too cold, the user touches the touch sensor with a finger one or more times. In response to the touch sensor detecting a touch, the control unit 151 accumulates the PMV value calculated at that time in the storage unit 131, and calculates a corrected PMVhot value and a corrected PMVcold value from the accumulated PMV value. The PMV value at this time is preferably in increments of 0.1. For example, among the PMV values accumulated in the storage unit 131, the control unit 151 feels that the most frequent PMV value when it is estimated to be hot from the latest 30-day data is corrected PMVhot value, cold. The most frequent PMV value at the time of estimation is taken as the corrected PMVcold value. And the control part 151 correct | amends the PMVhot value of the memory | storage part 131 with the calculated correction | amendment PMVhot and correction | amendment PMVcold value.

  As a fourth method, a calculation method of the corrected PMVhot value and the corrected PMVcold value by determining whether the user feels hot or cold according to the operation of the air-conditioning home appliance such as an air conditioner will be described.

  The sensor unit 110 further includes an infrared remote control reception sensor (not shown), and the infrared remote control reception sensor raises or lowers the set temperature in the cooling or heating operation when the user operates the infrared remote control of the air conditioner to start cooling or heating. Receives an infrared signal for the operation to be performed. The control unit 151 stores the PMV value calculated at that time in the storage unit 131 in response to the infrared remote control reception sensor receiving the infrared signal of the operation to the air conditioner, and corrects the corrected PMVhot value and the PMV value from the accumulated PMV value. A corrected PMVcold value is calculated. The PMV value at this time is preferably in increments of 0.1.

  For example, among the PMV values accumulated in the storage unit 131, the control unit 151 feels that the most frequent PMV value when it is estimated to be hot from the latest 30-day data is corrected PMVhot value, cold. The most frequent PMV value at the time of estimation is taken as the corrected PMVcold value. And the control part 151 correct | amends the PMVhot value of the memory | storage part 131 with the calculated correction | amendment PMVhot and correction | amendment PMVcold value. Note that the sensor unit 110 may not include the infrared remote control reception sensor, and may receive information on the operation of the air-conditioning home appliance from the external device 200 that remotely controls the home appliance such as a home appliance controller via the communication unit 140.

  As a fifth method, a method for calculating a corrected PMVhot value and a corrected PMVcold value by determining whether the user feels hot or cold by a thermal sensation determination method using the skin temperature of the peripheral part of the body will be described. .

  The sensor unit 110 further includes a peripheral skin temperature sensor (not shown). Based on the skin temperature acquired from the peripheral skin temperature sensor, the control unit 151 performs the thermal sensation determination method described in Patent Literatures 3 and 4. The storage unit 131 stores the PMV value when the state is switched from “hot” or “cold” to “hot” or “cold” from the state that is neither too hot nor too cold and vice versa. And the corrected PMVhot value and the corrected PMVcold value are calculated from the accumulated PMV value. The PMV value at this time is preferably in increments of 0.1.

  For example, among the PMV values accumulated in the storage unit 131, the control unit 151 feels that the most frequent PMV value when it is estimated to be hot from the latest 30-day data is corrected PMVhot value, cold. The most frequent PMV value at the time of estimation is taken as the corrected PMVcold value. Then, the control unit 151 corrects the PMVhot value in the storage unit 131 with the calculated corrected PMVhot value and corrected PMVcold value.

  The sensor unit 110 includes a peripheral skin temperature sensor in place of the in-clothes temperature / humidity sensor 111, and the control unit 151 starts from a state that is neither too hot nor too cold based on the skin temperature acquired from the peripheral skin temperature sensor. When the temperature is switched to “hot” or “cold” and the PMV value calculated at that time is in the range of “warm” or “cool”, a color instruction may be given to the color presentation unit 120. When both the PMV value and the thermal sensation determination based on the skin temperature are “too hot” or “too cold”, the control unit 151 does not present the color to the color presentation unit 120. By doing in this way, it can also be estimated whether it is unpleasant from a user's human body reaction.

  Note that the control unit 151 is provided in the external device 200, transmits necessary information to the external device 200, receives the corrected PMVhot value and the corrected PMVcold value, which are the processing results of the control unit 151, and receives the PMVhot value in the storage unit 131 and The PMVcold value may be corrected. Thereby, an increase in power consumption, an increase in size, and a weight of the glasses-type wearable device 100 can be suppressed.

  As described above, according to the present embodiment, as physiological response information, hypothermia and basal metabolism, parasympathetic and sympathetic nerve superiority, self-report whether the user is hot or cold, operation information of air-conditioning home appliances, By calculating the thermal sensation value that the user feels uncomfortable using the peripheral skin temperature and the peripheral skin temperature, the corrected PMVhot value and the corrected PMVcold value are calculated, and the storage unit is updated with the calculated value. It is possible to change the thermal sensation of the user more suitably using the human psychological reaction that the thermal sensation changes due to the above.
