Description

  The present invention relates to an environment control system that controls a user's environment.

  Conventionally, techniques for controlling the environment of a user (worker) have been proposed. The technique described in Patent Document 1 is an example.

  Specifically, the lighting control system described in Patent Document 1 detects personal physiological information, and based on the physiological information, in two stages, an aptitude level with a high arousal level and an inadequate level with a low arousal level. The state of individual consciousness is determined, and the illuminance when the state of consciousness is at an inappropriate level is increased. Thereby, this lighting control system can raise the awakening level in the day according to an individual's life rhythm.

JP 2009-266482 A

  However, it is not easy to detect physiological information for determining the state of consciousness of the worker who performs the intelligent work. For example, in Patent Document 1, a biosensor that detects a heart pulse is used to detect physiological information. It is not easy to prepare such a biosensor. In addition, the burden on the worker accompanying the detection of the pulse of the worker's heart is great.

  Moreover, even if the worker's awareness level is high, if the worker's consciousness is not concentrated on the intellectual work, the work efficiency of the intelligent work may be reduced. As a result, the work time increases, and the amount of power consumed for performing intelligent work may also increase.

  Therefore, an object of the present invention is to provide an environment control system or the like that can suppress a decrease in the efficiency of intelligent work.

  In order to achieve the above object, an environment control system according to an aspect of the present invention includes a detection unit that detects a decrease in the concentration level of a user who performs an intellectual work, and a decrease in the concentration level of the user, A recovery unit that recovers the user's concentration by changing the user's environment, and the detection unit is directed to the recovery unit from a direction for the user to perform the intelligent work. This is detected as a decrease in the user's concentration.

  In addition, an environment control method according to an aspect of the present invention includes a detection step of detecting a decrease in the concentration level of a user who performs an intelligent work, and the user environment when the decrease in the concentration level of the user is detected. A recovery step for recovering the user's concentration by changing, and in the detection step, the user turned his / her line of sight from a direction for performing the intelligent work to the recovery unit performing the recovery step. Is detected as a decrease in the user's concentration.

  The environment control system and the like according to one embodiment of the present invention can suppress a decrease in the efficiency of intelligent work.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that each of the embodiments described below shows a comprehensive or specific example. Numerical values, shapes, materials, components, arrangement positions and connection forms of components, order of operations, and the like shown in the following embodiments are merely examples, and are not intended to limit the present invention. In addition, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims indicating the highest concept are described as arbitrary constituent elements.

(Embodiment)
In the present embodiment, concentration means focusing attention on one matter and tackling things. The concentration level means the degree of concentration. That is, the degree of concentration means the degree to which attention is concentrated on one matter when tackling things. In addition, the degree of concentration affects the amount of intelligent work per unit time. The higher the degree of concentration, the larger the amount of intellectual work per unit time, and the lower the degree of concentration, the smaller the amount of intellectual work per unit time.

  Here, the intelligent work amount is the work amount of the intelligent work. The intelligent work is a work mainly performed using an operator's intellectual ability (intelligence), and is, for example, a work such as recognition, thinking, and determination. More specifically, the intellectual work is desk work or study.

  Further, a concentration time ratio (CTR) may be used as an index of concentration. The concentration time ratio is the ratio of the concentration state time to the total work time. This concentration time ratio may be used as an index for intellectual productivity evaluation.

  Note that awakening means waking up, and the arousal level indicates the degree of awakening. Although the concentration level may decrease due to a decrease in the arousal level, an increase in the arousal level does not necessarily cause an increase in the concentration level.

  FIG. 1 is a schematic diagram showing a transition model between a concentrated state and a non-concentrated state in the present embodiment. The state of the worker in the intelligent work is classified into three states: a work state, a short-term rest state, and a long-term rest state. The worker performs intelligent work while changing the state between these three states.

  The work state is a state in which the worker concentrates on the work and proceeds with the work. The short-term resting state is a state in which the operator concentrates on the work but unconsciously interrupts the work. In the short-term resting state, an interruption from several tens of milliseconds to several seconds is assumed. The long rest state is a state in which the worker is consciously interrupted by fatigue or the like. In the long-term resting state, interruption from several seconds to several tens of seconds is assumed.

  Mental fatigue increases in working and short resting states. And the probability that it will change to a long-term rest state will become high, so that mental fatigue is large. Long-term rest reduces mental fatigue. And the probability that it will change to a working state becomes high, so that mental fatigue is small.

  In this transition model, it is assumed that the worker's state transitions with a certain probability between the working state and the short-term resting state. The state transition probability and the change rate of mental fatigue vary according to the environment. The working state and the short-term resting state are states where the worker is concentrated on work and are included in the concentrated state. The long-term resting state is a state in which the worker is not concentrating on work and is included in a non-concentrating state.

  FIG. 2 is a schematic view illustrating characteristics of the concentrated state and the non-concentrated state shown in FIG. Specifically, FIG. 2 shows the frequency distribution of the answer time when answering the cognitive task problem, which is expected to have the same difficulty level and the same answer time. Each answer time is an answer time for one question. The horizontal axis indicates the logarithm of the answer time, and the vertical axis indicates the frequency of appearance of the answer time. That is, the vertical axis indicates the number of times the answer has been performed in the answer time interval on the horizontal axis.

  Since the worker's state transitions between the working state and the short-term resting state with a certain probability, the frequency distribution is represented by the lognormal distribution of the following Equation 1.

  Here, t indicates an answer time. f (t) represents the frequency of appearance of the answer time (t), that is, the number of times the answer was made at the answer time (t). μ represents the mode of the lognormal distribution. σ represents the variance of the lognormal distribution.

  On the other hand, when the worker's state transitions to the long-term rest state at the time of answering, the answering time becomes longer. As a result, a distribution different from the lognormal distribution is generated. As shown in FIG. 2, the lognormal distribution includes the distribution of answer times in the working state and the short rest state, and the distribution generated by the long rest state includes the work state, the short rest state, and the long rest state. It is assumed that the answer time distribution is included.

  The concentration time ratio is interpreted as the sum of answer times in the concentration state with respect to the sum of all answer times, and is expressed by the following equation (2).

  Here, CTR indicates a concentration time ratio.

は、集中状態における１問あたりの解答時間の平均値を示す。Ｎは、総解答数を示す。Ｔ_{ｔｏｔａｌ}は、総作業時間、すなわち、全解答時間の合計を示す。

Indicates the average answer time per question in a concentrated state. N indicates the total number of answers. _Ttotal indicates the total work time, that is, the total of all answer times.

  Further, the average value of the answer time per question in the concentrated state is obtained by Equation 3 as the expected value of the lognormal distribution of Equation 1.

  The expected value of the lognormal distribution is obtained by deriving an appropriate approximate curve of the lognormal distribution for the frequency distribution of the answer time. Then, a concentration time ratio is obtained based on the expected value, the total number of answers, and the total of all answer times. The concentration time ratio obtained according to the above is based on estimation of states such as a concentrated state and a non-concentrated state. Therefore, it is possible to appropriately evaluate the intellectual productivity and the degree of concentration by excluding the influence of learning of intellectual work by the concentration time ratio.

  Further, by obtaining the concentration time ratio at every predetermined time interval, it is possible to evaluate the transition of intellectual productivity and the transition of concentration level. The concentration time ratio is an example of an index of concentration level, and the concentration level may be obtained by another index. For example, the degree of concentration may be obtained based on characteristics of biological information obtained from a biological sensor, a work amount of intelligent work, or the like.

  The environment control system according to the present embodiment restores the concentration level by changing the environment at the timing when the concentration level of the user (worker) who performs the intelligent work is reduced. As a result, a decrease in the efficiency of intelligent work is suppressed.

  FIG. 3 is a block diagram showing the configuration of the environmental control system in the present embodiment. The environment control system 10 is a system that controls the environment of a user who performs intelligent work, and includes a detection unit 11 and a recovery unit 13.

  Moreover, the environment control system 10 may be a single device or a plurality of devices. For example, the detection unit 11 and the recovery unit 13 may be included in one device, or may be included in separate devices. In addition, components such as the detection unit 11 and the recovery unit 13 included in the environment control system 10 may be implemented by a dedicated or general-purpose electric circuit. These components may be communicable with each other by wire or wireless.

  The detection unit 11 is a detector that detects a decrease in the concentration of a user who performs intelligent work. A decrease in the concentration level means that the concentration level is lower than that in the immediately preceding state. In particular, the detection unit 11 detects that the user has turned his or her line of sight from the direction for performing intelligent work to the recovery unit 13 as a decrease in the user's concentration. The detection unit 11 may include an imaging unit 12. The imaging unit 12 is an imaging device that generates an image by imaging. The imaging unit 12 may perform imaging with visible light or may perform imaging with infrared rays.

  For example, the detection unit 11 generates an image of the user by imaging the user with the imaging unit 12. And the detection part 11 detects a user's eyes | visual_axis based on a user's image. The detection unit 11 may detect the user's line of sight by detecting the user's eyes, iris, corneal reflection, pupil, and the like in the image.

  Alternatively, the detection unit 11 may detect the orientation of the user's body or face based on the user's image, and detect the user's line of sight based on the orientation of the user's body or face. Specifically, the detection unit 11 may detect the orientation of the user's body or face as the orientation of the user's line of sight based on the user's image. Alternatively, the detection unit 11 detects the user's body, face, eyes, iris, corneal reflection, and part or all of the pupil based on the user's image, and detects the user's line of sight based on a combination thereof. May be.

  Based on the detected line of sight, the detection unit 11 detects whether or not the user's line of sight is directed to the recovery unit 13 from the direction for performing the intelligent work. Then, the detection unit 11 detects that the user's line of sight is directed to the recovery unit 13 from the direction for performing the intelligent work as a decrease in the user's concentration. Here, the direction for performing the intellectual work is a direction of an object used for the intelligent work, for example, a direction of a material, a book, a document, an information terminal, a desk, or the like used for the intelligent work.

  Note that the imaging unit 12 may not be included in the detection unit 11 and may not be included in the environment control system 10. The detection unit 11 may acquire a user image from the external imaging unit 12 and detect the user's line of sight based on the user image. Further, the detection unit 11 detects the user's line of sight by acquiring information indicating the user's line of sight, the user's face direction, or the user's body direction from the wearable terminal instead of the imaging unit 12. Also good.

  The imaging unit 12 may be a general-purpose imaging device mounted on a smartphone or the like. And the detection part 11 may be similarly mounted in the smart phone etc.

  As described above, the appropriate degree of concentration is derived based on the concentration time ratio. However, when the user is actually performing an intellectual work such as desk work or study, it is difficult to obtain the concentration time ratio by the cognitive task. Therefore, the detection unit 11 detects that the user's line of sight is directed to the recovery unit 13 from the direction for performing intelligent work as a decrease in the user's concentration.

  The state in which the user looks at the recovery unit 13 instead of the direction of performing the intellectual work is assumed to be a state in which the user does not concentrate attention on the intellectual work, and is assumed to be a long-term resting state. . Therefore, the detection unit 11 detects that the user's line of sight is directed to the recovery unit 13 from the direction for performing the intelligent work as a decrease in the user's concentration level, and thus the user's concentration level is simply and appropriately determined. A decrease can be detected.

  Further, as described above, the detection unit 11 detects that the user's line of sight is directed to the recovery unit 13 from the direction for performing intelligent work as a decrease in the user's concentration. As will be described later, the recovery unit 13 recovers the user's concentration by changing the user's environment when a decrease in the user's concentration is detected. That is, at the timing when the line of sight is directed to the recovery unit 13, the environment of the user changes for the recovery of the degree of concentration.

  When the user knows the above operation, it is assumed that the user turns his / her line of sight toward the recovery unit 13 to recover the concentration level at a timing when the user is aware of the decrease in the concentration level. Therefore, particularly when the user knows the above-described operation, the detection unit 11 can detect a decrease in the user's concentration degree at an appropriate timing.

  The recovery unit 13 is a recovery unit that recovers the concentration of the user who performs the intellectual work. In particular, the recovery unit 13 recovers the user concentration by changing the user environment when a decrease in the user concentration is detected. In other words, the recovery unit 13 changes the user environment so that the user concentration level is recovered when a decrease in the user concentration level is detected.

  The recovery unit 13 may include a blower unit 14, an illumination unit 15, a fragrance unit 16, or a sound generation unit 17. In addition, the recovery unit 13 may include two or more of the air blowing unit 14, the illumination unit 15, the scenting unit 16, and the sounding unit 17.

  The air blower 14 is a blower that blows air. The air blower 14 may be an air flow generator such as a fan or an air conditioner (air conditioner). The blower unit 14 changes the user's environment by changing the state of the blower when a decrease in the user's concentration is detected.

  For example, when a decrease in the concentration level of the user is detected, the air blowing unit 14 may apply a wind of about 0 m / s to 0.8 m / s to the vicinity of the upper body of the user. Specifically, when a decrease in the user's concentration level is detected, the air blowing unit 14 may perform air blowing that is greater than 0 m / s and 0.8 m / s or less from a state in which air is not being blown. From the state of blowing air stronger than 0.8 m / s, air of 0.8 m / s or less may be blown. Wind strength should not be constant.

  Or when the fall of a user's concentration degree is detected, the ventilation part 14 may apply the wind of 0.8 m / s-2.0 m / s to the vicinity of a user's face for 10 to 30 seconds. Alternatively, the air blowing unit 14 blows air of about 0 m / s to 0.8 m / s near the upper body of the user and wind of 0.8 m / s to 2.0 m / s near the user's face. You may perform both with the ventilation which hits.

  The illumination unit 15 is an illuminator that performs illumination. The illumination unit 15 may be an illuminator that performs task illumination or an illuminator that performs general illumination. The illumination unit 15 may include an illuminator that performs task illumination and an illuminator that performs general illumination. The illumination unit 15 changes the environment of the user by changing the illumination state when a decrease in the user's concentration is detected.

  For example, when a decrease in user concentration is detected, the illumination unit 15 may lower the color temperature of the illumination. Specifically, in the state where the color temperature of illumination is 6200K, when a decrease in the user's concentration is detected, the illumination unit 15 may reduce the color temperature of illumination to about 4000 to 5000K.

  Further, for example, when a decrease in the user's concentration is detected, the illumination unit 15 may decrease the illumination intensity of the illumination. Specifically, in a state where the illumination illuminance is 750 Lx, when a decrease in the user concentration is detected, the illumination unit 15 may reduce the illumination illuminance to about 300 Lx.

  For example, in the task ambient environment, when a decrease in user concentration is detected, the illumination unit 15 may widen the illumination irradiation range. Specifically, in a state where task lighting is being performed, when a decrease in user concentration is detected, the lighting unit 15 may turn off task lighting and turn on only general lighting. Alternatively, in the state where spot irradiation is being performed, when a decrease in user concentration is detected, the illumination unit 15 may switch the illumination from spot irradiation to general illumination.

  For example, when a decrease in the user's concentration is detected, the illumination unit 15 may change a plurality of elements among the color temperature, the illuminance, and the irradiation range of the illumination.

  The aroma generator 16 is an aroma generator that generates a scent. The aroma generator 16 may be an aroma generator. The fragrance part 16 changes a user's environment by changing the state of generation | occurrence | production of fragrance, when the fall of a user's concentration degree is detected. For example, when a decrease in the user's concentration is detected, the fragrance unit 16 may release a citrus scent or the like in the vicinity of the user's face. The released scent is not limited to a citrus scent, but may be a user's favorite scent.

  The sound generation unit 17 is a sound generator that generates sound. The sound generator 17 may be an audio player or a music player. The sound generation unit 17 changes the user's environment by changing the state of sound generation when a decrease in the user's concentration is detected. For example, when a decrease in the user's concentration is detected, the sound generation unit 17 may reproduce the natural environment sound or the like at about 30 to 50 db.

  The recovery unit 13 promotes a physiological or psychological refresh for the user by changing the user's environment as described above when a decrease in the user's concentration is detected, and the user's mental fatigue. Decrease. Thereby, the recovery unit 13 recovers the user's concentration.

  It is difficult to maintain a state of high concentration for a long time. Therefore, as described above, the recovery unit 13 reduces the mental fatigue of the user by an operation for refreshing the user, for example, a decrease in illuminance, a decrease in color temperature, and an expansion of the irradiation range. In other words, the recovery unit 13 temporarily reduces the concentration level, and thereafter recovers the concentration level to a high state.

  The above-described operation related to the recovery unit 13 is an example, and the recovery unit 13 performs the degree of concentration by an operation opposite to the above-described operation, that is, by increasing the illuminance, increasing the color temperature, and reducing the irradiation range. May be raised directly.

  The recovery unit 13 may recover the user's concentration by changing other environmental factors. For example, the recovery unit 13 may recover the user's concentration by changing temperature or humidity. In this case, the recovery unit 13 may not include any of the blower unit 14, the illumination unit 15, the fragrance unit 16, and the sound generation unit 17. The recovery unit 13 may recover the user's concentration by changing a plurality of environmental elements.

  Further, the recovery unit 13 may reverse the change in the user environment after a predetermined period has elapsed since the user environment was changed. That is, the recovery unit 13 changes the user's environment when a decrease in the user's concentration is detected, and based on the change in the user's environment after a predetermined period of time has elapsed since the user's environment was changed. By returning, the user's concentration may be recovered.

  For example, the recovery unit 13 temporarily reduces the concentration level by changing the user's environment, and recovers the concentration level by reverting the change in the environment. That is, the recovery unit 13 changes the environment of the user so that the concentration level temporarily decreases, and then restores the environment change so that the concentration level recovers. Thereby, the recovery of the concentration level is promoted. In addition, after the user's mental fatigue is reduced, the user's concentration is restored. Therefore, the recovery unit 13 can maintain the concentration level at a high level after recovering the concentration level.

  Specifically, the recovery unit 13 starts an operation for changing the user's environment when a decrease in the degree of concentration is detected, and performs the operation after a lapse of a predetermined period from the start of the operation. You may stop. For example, when a decrease in the degree of concentration is detected, the air blowing unit 14 starts air blowing, and stops air blowing after a predetermined period of time has elapsed since the start of air blowing.

  Further, for example, when a decrease in the degree of concentration is detected, the illumination unit 15 changes the color temperature, illuminance, and irradiation range of the illumination, and changes the color temperature, illuminance, and irradiation range of the illumination for a predetermined period. After the lapse of time, the color temperature, illuminance and irradiation range of the illumination are returned to the state before the change.

  In addition, for example, when a decrease in the degree of concentration is detected, the scenting unit 16 starts an operation for generating a scent, and generates a scent after a predetermined period has elapsed since the start of the operation for generating a scent. Stop operation. In addition, for example, the sound generation unit 17 starts an operation for generating a sound when a decrease in the degree of concentration is detected, and an operation for generating a sound after a predetermined period of time has elapsed since the operation for generating the sound was started. To stop.

  In the above description, the predetermined period from when the user's environment is changed to when the change in the user's environment is restored is, for example, about 10 to 30 seconds, but may be shorter than 10 seconds or 30 seconds. May be longer. This predetermined period may be, for example, about 5 to 60 seconds. This predetermined period may be shorter or longer.

  Further, the recovery unit 13 determines a period from the change of the user environment to the return of the change of the user environment according to the total work time of the intelligent work or the elapsed time from the start of the intelligent work. May be. Specifically, the longer the total work time of the intellectual work or the elapsed time from the start of the intelligent work, the longer the period from the change of the user environment to the return of the change of the user environment. May be.

  Note that the recovery unit 13 does not necessarily need to undo changes in the user's environment. The recovery unit 13 can reduce the mental fatigue of the user by changing the user's environment so that the degree of concentration temporarily decreases. And it is assumed that a user's concentration will recover by reducing a user's mental fatigue. Therefore, the recovery unit 13 may recover the user's concentration without changing the user's environment back to the original by changing the user's environment so that the concentration decreases temporarily.

  Further, the recovery unit 13 may change the environment of the user so that the degree of concentration increases without temporarily decreasing. Thereby, the recovery unit 13 may recover the user's concentration without undone the change in the user's environment. However, the recovery unit 13 may reverse the change in the user's environment so that the user's environment can be changed at the next timing when the user's concentration level decreases.

  Further, the concentration time ratio may be measured in an experiment in which the user's concentration level is recovered by a change in the environment. Thereby, it is possible to verify whether or not the user concentration level is restored. Moreover, the environment control system 10 may include a measurement unit that measures the concentration time ratio by continuously presenting the cognitive task to the user and acquiring the answer time of the cognitive task.

  FIG. 4 is a flowchart showing the operation of the environment control system 10 shown in FIG. First, the detection unit 11 detects a decrease in the degree of concentration of a user who performs intelligent work. Specifically, the detection unit 11 detects that the user has turned his / her line of sight toward the recovery unit 13 from the direction for performing the intelligent work as a decrease in the user's concentration (S11). And when the fall of a user's concentration level is detected, the recovery part 13 recovers a user's concentration level by changing a user's environment (S12).

  Thereby, the environment control system 10 can detect the fall of a user's concentration degree simply and appropriately. The environment control system 10 can recover the user's concentration by changing the user's environment at an appropriate timing. Therefore, the environment control system 10 can suppress a decrease in the efficiency of intelligent work. And by suppressing the efficiency fall of an intelligent work, the increase in work time is suppressed and the increase in the power consumption amount for performing an intelligent work is suppressed.

  FIG. 5 is a conceptual diagram showing an application example of the environment control system 10 shown in FIG. FIG. 5 shows an imaging device 21, blower devices 22 and 23, illumination devices 24 and 25, a fragrance device 26, and a sound generator device 27. These components may be able to communicate with each other in a wired or wireless manner. In FIG. 5, an alternate long and short dash line indicates a direction for the user to perform intelligent work.

  The imaging device 21 is an example of the detection unit 11 or the imaging unit 12 illustrated in FIG. The imaging device 21 may be a camera, a video camera, a visible light camera, or an infrared camera. The imaging device 21 detects a decrease in the degree of concentration of a user who performs an intelligent work. In particular, the imaging device 21 detects that the user's line of sight is directed to the blower device 22 or the like that is an example of the recovery unit 13 from the direction in which the user performs intelligent work as a decrease in the user's concentration.

  For example, the imaging device 21 generates a user image by imaging the user with visible light or infrared light. And the imaging device 21 detects a user's eyes | visual_axis based on a user's image. Specifically, the imaging device 21 detects the user's line of sight by detecting part or all of the user's body, face, eyes, iris, corneal reflection, pupil, and the like in the image.

  Then, the imaging device 21 detects whether or not the user's line of sight is directed to the blower 22 or the like from the direction for performing the intelligent work based on the detected line of sight. Then, the imaging device 21 detects that the user's line of sight is directed from the direction for performing intelligent work toward the blower 22 and the like as a decrease in the user's concentration.

  The direction for performing the intelligent work may be determined in advance by a user input or the like. Alternatively, the imaging device 21 may detect a book, a document, an information terminal, a desk, and the like from the image, and detect a direction from the user toward the book, the document, the information terminal, the desk, and the like as a direction for intelligent work. . Alternatively, when the user's line of sight is directed in the same direction for a predetermined period or longer, the imaging device 21 detects that the user is performing an intelligent work, and the line of sight directed in the same direction for a predetermined period or longer is detected. The direction may be detected as a direction for intelligent work.

  Further, the position of the blower 22 or the like may be determined in advance by a user input or the like. Alternatively, the imaging device 21 may detect the position of the blower 22 or the like by detecting the blower 22 or the like from the image. Then, the imaging device 21 may detect that the user's line of sight is directed from the direction for performing intelligent work to a position such as the blower 22 as a decrease in the user's concentration.

  The imaging device 21 may detect the position of the user from the image. Then, the imaging device 21 is based on the position of the user and the direction of the user's line of sight. You may detect that it is pointing.

  Here, the imaging device 21 is installed independently of the blower 22 and the like, but the imaging device 21 may be included in the blower 22 and the like. Moreover, the imaging device 21 may be included in an information terminal or the like for a user to perform an intelligent work. Moreover, the imaging device 21 may generate a user image, and the blower device 22 or the like may detect the user's line of sight based on the user image.

  The air blowers 22 and 23 are examples of the recovery unit 13 or the air blower 14 illustrated in FIG. For example, the air blower 22 is a personal fan, and the air blower 23 is an air conditioner (air conditioner).

  The air blowers 22 and 23 recover the user concentration by changing the user environment when a decrease in the user concentration is detected. In particular, the blowing devices 22 and 23 change the user's environment by changing the blowing state when a decrease in the user's concentration is detected. Only one of the blowing devices 22 and 23 may operate as the recovery unit 13 or the blowing unit 14.

  For example, when a decrease in the concentration level of the user is detected, the blower 22 may apply a wind of about 0 m / s to 0.8 m / s to the vicinity of the upper body of the user. Moreover, when the fall of a user's concentration degree is detected, the air blower 22 may apply the wind of 0.8 m / s-2.0 m / s to the vicinity of a user's face. The blower 23 may perform these operations instead of the blower 22, or both the blowers 22 and 23 may perform these operations.

  In addition, when a decrease in the user's concentration is detected in a state where the air blower 23 performs overall air blowing, the air blower 23 stops the overall air blowing, and the air blower 22 is placed on the user's upper body or face. You may blow toward.
