Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims to help maintain the physical and mental condition of a living body including a population or to improve its ability, for example, prevention / elimination of stress, fatigue reduction / recovery, and educational effect. For the purpose of improvement, improvement of entertainment effect, improvement of work efficiency, promotion of growth, etc., by adapting to the state of the living body or by stimulating the living body, by changing the state of the living body, Relaxed, less tired, focused, excited,
It relates to devices that create favorable conditions such as interesting, interesting, and growing.

[0002]

2. Description of the Related Art As an example of a device for artificially changing the condition of an individual, there is a medical device approval number (01B) No. 116.
There is No. 6 stiff shoulder device, and a synchro energizer developed in the United States in 1983 by Mr. Dennis Gorges, an American neuroneurologist for the purpose of relieving stress.

These devices have no means for knowing the state of the living body, and cannot perform appropriate treatment according to the state of the living body, and thus the safety of the living body is threatened. Despite the expected accident, there was a problem that it lacked a device to guarantee perfection.

For the purpose of improving these problems, a "biological function adjusting device" of Japanese Patent Application No. 2-213892 has been proposed.

Regarding a device that adapts to the state of a living body, an interface technology that allows a user who does not have knowledge of the interface system to quickly execute the intended operation, for example, by Mr. Masahiro Sakata and Mr. Kensho Tsuchida in 1990. In October, there is a technology such as "Customization of user interface using user model", which was presented on pages 61-66 of the 6th Human Interface Symposium Proceedings.

[0006]

The problems of the conventional device are listed below.

1. Since the determination of the state of the living body is performed based on the measured raw numerical data, for example, the heart rate = 5
If it is 0, it is judged that the stimulus is stopped, and since the coefficient of the mathematical formula used for the calculation for control / adaptation is kept constant once it is between the individual differences and the characteristics of the population. It is difficult to deal with variations.

2. Since the state of the living body depends on the environment in which it is placed, when controlling / adapting the state of the living body, better control / adaptation can be performed by observing the state of the environment, but there is no means for measuring the environment.

3. Although it is better to estimate the state of a living body together with information on the environment in which the living body is placed, it lacks a measure for that purpose.

4. It has no means to manipulate the environment.

5. When estimating the state of a living body, although it is possible to perform efficient estimation by using the prior knowledge about the living body, there is a lack of measures for utilizing the prior knowledge.

6. In order to guarantee the safety of the living body, it is better to monitor not only the raw numerical data obtained by measuring the living body, for example, the data such as heart rate, but also the state of the living body, for example, the state of "quite tired". But
Only raw data are used.

7. In order to guarantee the safety of the living body, the state of the environment must be guaranteed, but it does not have the means.

8. In order to finally guarantee the operating status of the device, humans externally operate the system, the condition of the living body,
It is necessary to be able to monitor the condition of the environment where the living body is placed,
I don't have that means.

9. Depending on the operating state of the system, the state of the living body, and the state of the environment, it may be better for humans to directly control the device from the outside, but there is no way to do so.

10. In order to improve and improve the device, it is necessary to standardize the data obtained from a certain individual and compare it with the data of another individual or another group of individuals, but there is no measure for that.

11. Generally, a plurality of sensors required for measuring biometric information are required, but if all of these sensors are used, it may take time for estimation, and the efficiency of control / adaptation may be lowered.

12. It is desirable to select and use an appropriate sensor from a plurality of prepared sensors, since there is a danger of causing a serious problem if the failed sensor is used as it is, but such a mechanism is lacking.

13. The skin resistance value is an effective index for knowing the degree of tension of the autonomic nervous system of the human body, but it is not used because its measurement requires a troublesome procedure such as sticking an electrode to a living body.

14. As indicators of the reaction state of the human body's autonomous system, in addition to electrodermal activity, there are indicators such as pilus muscle movement, salivary secretion reaction, saliva component, shoulder stiffness, etc. Not available because there is no.

15. A method of measuring a subjective sensation, for example, a sway sensation by an objective index and a method of measuring a growth rate of a plant by an objective index cannot be used because there is no suitable sensor for measuring this.

16. Experiential stimuli and stimuli that use the illusion of the human body are expected to be used in the fields of games and simulations, but the most common sensations are terrain, aftereffects of motion as an illusion, and the presentation of motion sensations. There is no device and these stimuli are not available.

17. For the purpose, the danger signal as a stimulus given to the human body needs to be a signal that does not easily get used to the human body, and although the point pain sensation can be said to be most suitable, a device that gives this as a danger signal This is not available because there was no. The above is the problem of the conventional device.

The purpose of the present invention is as follows.

1. It is assumed that the reference data for control / adaptation is estimated from biometric information rather than raw numerical data, has a small individual difference, and is more general “biological condition”, for example, “terribly tired”.

2. Coefficients used for calculation for control / adaptation can be automatically changed according to the characteristics of individuals or groups of individuals, thereby facilitating coping with individual differences.

3. Measure the environment around the living body.

4. The biological condition is estimated together with the environmental measurement result.

5. Enables manipulation of the environment around the living body.

6. Make prior knowledge of living body available for estimation of living body state.

7. In order to guarantee the safety of the living body, the living body condition is used, and the state of the environment is monitored for the safety of the living body.

8. In order to finally guarantee the operating status of the device, a human being externally monitors the current living body state and the state of the environment where the living body is placed.

9. Depending on the condition of the living body and the environment,
A person directly controls the device from the outside.

10. It has a data standardization mechanism to compare data between individuals or groups of individuals to improve and improve the equipment.

11. It has a mechanism that allows you to select an appropriate sensor from multiple sensors.

12. Among the reaction states of the autonomic nervous system, skin resistance, pili muscle movement, salivary reaction, saliva component, shoulder stiffness, etc. are measured and used to objectively measure the sway sensation and the growth rate of the plant. Is measured by an objective index.

13. Terrain,
It has devices for post-motion aftereffect, presentation of sway sensation, and application of pain stimulus as a danger signal.

A small amount of air is blown into the air supply pipe 57 to reduce the amount of saliva adhering to the sensor 52, and when the air supply is stopped at a certain point, the saliva secreted later from that point is used as the air supply pipe 57. Since the tip of the sensor is filled and a large amount of saliva adheres to the sensor 52, the indicated value of the sensor 52 changes. Based on this, saliva secretion is detected. The secreted saliva can also be collected via the saliva suction tube 56.

To examine the salivary secretion reaction, a small amount of a taste stimulating substance (an aqueous solution of a taste substance such as amino acids, sugars and salts) is injected onto the tongue and immediately recovered, and saliva secretion observed thereafter is measured. It should be detected.

If saliva secretion is measured before the ejection of the taste stimulating substance, the salivary secretion reaction to the taste stimulating substance can be observed.

The taste stimulating substance is ejected from the taste stimulating substance ejecting pipe 55 located on the tongue 50, and the taste stimulating substance is ejected by the taste stimulating substance aspirating pipe 54 located right next to the taste stimulating substance ejecting pipe 55. It can be realized.
