【Example】

Example 1. FIG. 1 is a block diagram of an embodiment in which the invention according to claim 3 is added to the invention according to claim 1.
In FIG. 1, 11 is a physiological reaction measurement unit, 12 is a biological signal processing unit, 13 is a state evaluation unit, 14 is a declared value input unit, 17
Is a control system determination unit, 18 is a control signal generation unit, 19 is an environment control unit, and 20 is an external environment parameter measurement unit.
3, 18 20 is exactly the same as the conventional example. In the control system determination unit 17, 171 is a sense target value, 172 is a state evaluation value, and 175 is a system determination unit. Further, b is a declared value, c1 is a past sense value error, and c2 is a present sense value error. Further, according to the third aspect of the invention, 15 situation input parts and situation information of a are added.

Next, the operation will be described. A plurality of physiological reactions such as an electroencephalogram, an electrocardiogram, and a pulse wave detected by a plurality of sensors and transducers in the physiological response measurement unit 11 are
Pre-processing such as amplification and filtering is performed, and the biological signal processing unit 14 performs electroencephalogram α-wave power and frequency, instantaneous heartbeat value,
Evaluation parameters such as respiratory heart rate variability, T wave height, respiratory waveform, and pulse wave height are calculated and input to the state evaluation unit 15. The state evaluation unit 15 converts these into an internal physiological amount of the living body by a physiological reaction model, and in consideration of the physiological mechanism, the activity and balance of the sympathetic system / parasympathetic system from the cardiovascular index, and activation of the central system from the electroencephalogram. The degree of comfort or negative comfort is estimated by the physiological / sensory correlation model, and the sensory levels, such as arousal level and drowsiness level, in multiple evaluation axes in the multidimensional semantic space are estimated. , Comfort level is estimated in real time by estimating as on-axis sensory quantities such as fatigue level, mental burden level, and physical comfort level, and outputting as state evaluation values. This output is continuously input to the control method determination unit 17. From the above physiological reaction measurement,
The processes leading to the estimation of the internal physiological amount and the estimation of the sensory amount may be similar to those in the conventional example.

On the other hand, from the declared value input unit 14, the declared value b, which is the subjective evaluation data of the person to be measured, is intermittently or sequentially at a time interval longer than the state evaluation value, and the control method determination unit 17 is provided.
Entered in. The input value of the declared value b is an analog value by a lever or a step value by pressing a button.
The declared value b is the same as or part of the evaluation axis of the sensory amount estimated by the state evaluation unit 13, for example, stress or fatigue, but may include the response to the evaluation axis other than the estimation. Further, the declared value b may be input by the observer himself, or may be input by an observer in the case of a person who cannot be verbalized or cannot be input, such as an infant, an elderly person, a sick person, or a disabled person. Further, as in the conventional example, it may be used for calibration when estimating the sense amount.

Next, the control method determination unit 17 determines an environment control method suitable for an individual by using the state evaluation value 172 continuously input and the declared value b intermittently input. First, either the state evaluation value 172 or the declared value b input with less frequency is selected as the input sense value, and the difference between this and the preset sense target value 171 is calculated. The sensory target value 171 is preset for each dimension in the multidimensional meaning space, such as comfort level 5 and alertness level 3. As a difference between these and the input sense value, a difference, a ratio, a pattern difference, a distance, etc. are obtained as the sense value error c1. Since the declared value b, which is a subjective evaluation, is intermittently input with a frequency less than the state evaluation value 172, if this value is input, it is selected as the input sense value, and otherwise the state evaluation value 172 is used. A switch may be used. As the declared value b, for convenience, a subjective evaluation value for a part of the evaluation axis of the state evaluation value 172 is used. When this is selected, the input sense value is replaced, and the evaluation axis not used for the declared value b is Keep the previous value.

Based on the sensory value error c2, the system determining unit 175 determines the degree to each controlled object and the combination of the controlled objects, that is, which parameter of which environment, such as air conditioning and lighting, is operated, that is, the temperature. , An environment control method such as humidity, scent, brightness, illuminance, BGM volume, and the control amount thereof is determined. As an initial setting, an environment control method determination algorithm determined from average person data may be used. The environment control method is determined by, for example, raising the temperature of the air conditioning and lowering the brightness of the illumination when the sense target value is the comfort level 5 and the sense value error c1 is (+2) as the input sense value 3 Determine the method of.
For example, if the stress level and fatigue level increase due to the sensory value error pattern, turn off the lighting a little and lightly play BGM,
When a scent that promotes a soothing effect is generated and the alertness level drops,
Brighten the lighting, BGM will change to light music, and decide the method such as generating a scent and cool air with a refreshing effect.

Based on the determined method, the environment control signal generation unit 18 converts this into a control signal for controlling the environment of, for example, air conditioning, lighting, AV equipment, etc., and sends it to the environment control unit 19 to send the environment. The control unit 19 adds control to the air conditioner, lighting, AV equipment, etc., while taking into consideration the environment information from the external environment parameter measuring unit 20 including various sensors such as temperature and humidity.

From the above, the environment control is added, and the sense value error c2 after the environment control is input again to the system determining unit 175. The change between this and the sense value error c1 before the environment control is used as a teacher to learn the environment. The environmental control method determined before control is adaptively changed. For example, when the environment information changes, the comfort level of the input sense value after the environment control becomes 4, and the sense value error c2 becomes (+
Assuming 1), this and the sense value error c before environmental control
Change from 1 (+2), that is, (-1) It was calculated that there was an effect in the comfortable direction, and when a change in the desired direction such as comfort improvement and stress reduction was obtained, select that method, When the opposite effect is obtained, the algorithm for adaptively determining the environmental control method is changed according to the condition of the individual such as not selecting the method from the next time. The method of changing the algorithm is, for example, simply 0/1 (on / off)
In addition to selecting the combination of methods, the priority and weight of each control method (means and control amount) are changed. Alternatively,
Modification of the membership function for fuzzy control, modification of the fuzzy table obtained from the membership function, configuration of the neural network that outputs the environmental control method with the sensory error value c1 as input, and before and after environmental control The weighting for determining the environment control method may be learned using the change in the sensory value error of as a teacher signal. Further, the declared value b that is input less frequently than the state evaluation value 172 may play a role of calibration for preventing erroneous learning, and thus the importance at the time of determination may be increased.

The targets of environmental control include air quality of air conditioners, temperature / humidity and scent generation, brightness and direction of lighting, number of lights to be turned on, volume of BGM of AV equipment and selection of image information to be presented, Other examples include a CRT display screen (controlling a display image such as making it easy to see or displaying a message) and a work amount at the time of working with an OA device, but the present invention is not limited to the embodiment.

The above-described operations are sequentially performed, and the characteristics of the person to be measured, such as sex, age, body type, amount of exercise, type of work, work form, personality, and behavioral characteristics, are not necessarily taken into consideration By using the environment control method, it is possible to evaluate comfort in real time and perform control for creating a more comfortable environment. However, in the evaluation of physiological responses, consideration should be given to factors such as the influence of age such as respiratory heart rate variability, etc., and when estimating sensory amounts, elderly people and children should take into consideration that the evaluation threshold for stress level should be slightly relaxed. If a more accurate evaluation can be performed, attribute information may be input as in the conventional example and evaluation may be performed in consideration of this.

According to the third aspect of the present invention, by adding the situation input unit 15, not only the characteristics of each individual but also the working space such as office or plant monitoring work from the working space such as the living room or the bedroom to the individual. You can learn the environment control method corresponding to various situations. It is considered that comfort is different in the appropriate range of evaluation axis and sensory amount, which are important in various situations, such as moderate tension and arousal level when working in a plant, and relaxation level when relaxing in the living room or bathroom. To be Therefore, first, a plurality of sets of sensory target values on a plurality of evaluation axes in a multidimensional semantic space are set in advance for each scene or situation. When determining the environment control method, the sense value error is obtained using the sense target value selected from a plurality of sets of sense target values set in advance for each situation in accordance with the situation information from the situation input unit 15. , Which determines the environment control method. When learning the environmental control method, first, when the status information a is input from the status input unit 15 at the time of starting the system or when the scene or the status changes, the environmental control method for each status is learned. . Alternatively, the sensory target value 171 is set for each situation, and the environmental control method is learned from the change in the sensory value error obtained using this before and after the environmental control, and the environmental control method is determined according to various situations. To be done. The situation input unit 15 may perform the scene or situation by selecting a menu screen or an item-by-item selection switch. The situation information a is a scene to be controlled, the situation of the person being measured, or a combination thereof,
For example, plant control room, living room, conference room, car, living room,
It is advisable to input scenes such as bedrooms, bathrooms, study rooms, situations such as terminal work, monitoring work, breaks, relaxation, relaxation, sleep, or a combination thereof. Even if the controlled scene is the same, if the desired comfort target value may differ depending on the situation, information about this may also be required. The initial value of the sensory target value 171 is set in advance to a target value obtained from an average person in each situation, or the target value itself considering the weighting of individual evaluation.

In Item 2, the environment control method is determined from the state evaluation values related to the physiological reaction such as the physiological reaction evaluation parameter and the internal physiological amount obtained by using the physiological reaction model without estimating the sensory amount. However, in this case, a state target value relating to a physiological reaction which is a reference is required. That is, the physiological reaction is measured by the physiological reaction measurement unit 11, a plurality of evaluation parameters are extracted by the biological signal processing unit 12, and the second state evaluation unit 1

Alternatively, the evaluation parameter itself may be used as the second state evaluation value 174 without performing any processing. In the control method determination unit 16, the second state evaluation value 174 and the preset physiological reaction state target value 17 are set.
The difference from 3 is obtained as the state value error d, and this is used to determine the environment control method. On the other hand, when the declared value b is input intermittently or less frequently than the second state evaluation value 174, the difference between the declared value b and the sensation target value 171 is sent to the second method determination unit 176 as the sensation value error c1. Is entered. Second
The method determining unit 176 adaptively changes the algorithm for determining the environmental control method from the changes in the sense value error c1 before the environmental control and the sense value error c2 after the environmental control, as in the first aspect. Based on this, an environmental control signal is generated from the control signal generation unit 18, the environmental control unit 19 performs environmental control while considering the environmental information from the external environmental parameter measurement unit, and these are sequentially performed to correspond to each individual. The algorithm for determining the environmental control method is learned.

Further, according to the invention of claim 4, by adding the situation input section 15 and the situation information a, it is possible to determine and learn the environment control method according to various situations and scenes. In this case, in determining the environment control method, it is necessary to set a plurality of preset state target values for each situation. For example, the sympathetic system index during relaxation is 20% or less of stress load, 100% activation of parasympathetic system, 40% or less of sympathetic system and 70% of parasympathetic system during work. Multiple sets are set and the state target value according to the input situation is selected from these, and this and the second
The environmental control method is determined by the state value error d, which is the difference from the state evaluation value 174. Further, in learning the environment control method, as in the first embodiment, it is necessary to set a plurality of sensory target value sets set in advance for each situation, and the situation input unit 1
