Description

Description: TECHNICAL FIELD The present invention relates to a stress relief device that relaxes the mind and body by vibrating vibrations applied to key points of the body.

BACKGROUND ART Conventionally, this type of stress relieving device that relaxes the mind and body by vibrations applied to important points of the body has been measured by measuring the electrical resistance of the skin of the user at a resistance measuring unit. Vibration strength at the next time based on the skin electric resistance at a certain time and a preset feedback coefficient (a coefficient that sets how much the signal strength should be weakened when the skin electric resistance changes) Was determined, and vibration was applied to important points of the body (for example, legs) to relax the mind and body while checking the relaxed state based on the electrical resistance of the skin. However, in such a conventional example, there is a problem that the desired stress relieving effect may not be obtained due to individual differences in the rate of change of the skin electrical resistance in the relaxed state from the initial state. In other words, the rate of change in skin electrical resistance varies widely from person to person, and even if the person is similarly relaxed, the rate of change of one person is 1.2.
Although there is variation such that the rate of change of a person is triple, in the conventional example, the feedback coefficient is fixed (for example, doubled when the rate of change has a large individual difference). Since the vibration is set to 0 when it is used), the optimum vibration for relaxing the mind and body may not be given, and there is individual difference in the degree of relaxation, and the desired stress relief effect is obtained. There was a problem that it might not exist.

[Object of the Invention] The present invention has been made in view of the above points, and it is an object of the present invention to obtain the same stress relieving effect regardless of individual differences in the rate of change of skin electrical resistance, and An object of the present invention is to provide a stress relieving device that can increase the stress relieving effect of the same user as the number of times of use by the same user increases.

DISCLOSURE OF THE INVENTION (Structure) The present invention relates to a resistance measuring unit that measures the skin electrical resistance of a main part of a user, a change rate of the skin electrical resistance at each time with respect to an initial value, and the previous time described in the storage unit. A calculation processing unit that determines the vibration intensity at the next time from the set feedback coefficient, and a vibration that has the vibration intensity determined by the calculation processing unit and that has a frequency that changes with 1 / f fluctuation It is composed of a vibration generating part that generates, a feedback coefficient at the time of first use is appropriately set, and at the end of use, changes in skin electrical resistance with respect to the initial value when a preset time elapses from the start of use this time. By forming the arithmetic processing unit so as to determine the next feedback coefficient from the rate and the previous feedback coefficient and store it in the storage unit, the same can be obtained regardless of individual differences in the rate of change in skin electrical resistance. Stress effect is obtained of, moreover there is provided a stress device capable of increasing the stress effect of the user The more times using the same user.

(Embodiment) FIG. 1 shows an embodiment of the present invention. The resistance measuring unit 1 for measuring the skin electrical resistance SRL of the main part of the user and the rate of change of the skin electrical resistance SRL with respect to the initial value at each time. The calculation processing unit 2 determines the vibration intensity at the next time from the previously set feedback coefficient stored in the storage unit 3, and the vibration intensity determined by the calculation processing unit 2. 1 /
f It is composed of a vibration generator 4 that generates vibrations having a frequency (tens of Hz to several tens of Hz) that changes due to fluctuations, sets the feedback coefficient at the time of first use appropriately, and uses this time at the end of use. The arithmetic processing unit 2 is configured to determine the next feedback coefficient from the rate of change of the electrical resistance SRL of the skin when the preset time has elapsed from the start with respect to the initial value and the previous feedback coefficient, and store the feedback coefficient in the storage unit 3. It was formed. Here, in the embodiment, the resistance measuring unit 1 is a resistance sensor attached to a user's finger or the like.
The vibration generator 4 is formed of a vibration control circuit 4a and a vibration means 4b.

The operation of the embodiment will be described below. Now, in the resistance measuring unit 1, the skin electrical resistance SRL is measured at a constant time interval (for example, 10 seconds) based on the output of the resistance sensor 1a and is input to the arithmetic processing unit 2. In the arithmetic processing unit 2 to which the measured value of the skin electrical resistance SRL is input, the second value for setting the relationship between the rate of change of the skin electrical resistance SRL and the vibration intensity is set.
The strength of vibration at the next time is determined based on the feedback coefficient curve shown in FIG. 10A and the skin electrical resistance SRL at each time, and the vibration control circuit 4a of the vibration generator 4 calculates The vibrating means 4b is controlled so as to generate the vibration having the vibration intensity determined by the processing unit 2 and the frequency changing with 1 / f fluctuation, and the vibration generated by the vibrating means 4a is the user. Is applied to the main part of the body (for example, a foot), and the strength of vibration is feedback-controlled so that the body can be relaxed.

By the way, as the feedback coefficient for determining the vibration intensity at the next time, an appropriate preset coefficient stored in the storage unit 3 is used at the first use,
At the time of the second and subsequent uses, the feedback coefficient corrected according to the actually measured change rate of the user's skin electrical resistance SRL at the end of the previous time is used. That is, in the arithmetic processing unit 2, at the end of use, the next feedback coefficient is calculated from the rate of change of the skin electrical resistance SRL with respect to the initial value when a preset time has elapsed from the start of use this time and the previous feedback coefficient. It is configured to be determined and stored in the storage unit 3. For example, if the previous feedback coefficient curve is as shown in Fig. 2 (a) and the rate of change of the skin electrical resistance SRL at the time of use this time is as shown in Fig. 2 (b), The feedback coefficient for the next use is determined based on the rate of change (1.4) after the elapse of the predetermined time T ₀ and the rate of change (2.0) that was the basis for determining the feedback coefficient for the previous use, and the feedback coefficient for the next use is stored in the storage unit 3. It is designed to be remembered. In the case of the illustrated example, the feedback coefficient as shown in FIG. 2 (c) is determined based on the average value (1.7) of both change rates, and is stored in the storage unit 3 as the feedback coefficient for the next use. It has become. In this case, the feedback coefficient is automatically corrected based on the change rate of the skin electrical resistance SRL at the time of previous use so that the optimum feedback coefficient can be driven.
Even if there are individual differences in the change rate of skin electrical resistance SRL, it is possible to apply vibrations according to individual differences due to the so-called learning effect. The effect of elimination will be obtained. Further, the learning effect becomes more remarkable as the number of times of use by the same user increases, so that the user can enhance the stress relieving effect.

[Effects of the Invention] As described above, the present invention is stored in the resistance measuring unit for measuring the skin electrical resistance of the main part of the user, the change rate of the skin electrical resistance at each time with respect to the initial value, and the storage unit. A calculation processing unit that determines the vibration intensity at the next time from the previously set feedback coefficient, and a vibration that has the vibration intensity determined by the calculation processing unit and that has a frequency that changes with 1 / f fluctuation It is composed of a vibration generating part that generates a feedback coefficient at the time of first use, and at the end of use, the initial value of skin electrical resistance when a preset time elapses from the start of use The calculation processing unit is formed so as to determine the next feedback coefficient from the rate of change and the previous feedback coefficient and store it in the storage unit, and a feed that determines the vibration intensity at the next time. The back coefficient is automatically corrected based on the rate of change in skin electrical resistance at the time of previous use so that a more optimal feedback coefficient can be obtained, so even if there is individual variation in the rate of change in skin electrical resistance. The so-called learning effect makes it possible to apply vibrations according to individual differences, and similar stress relief effects can be obtained regardless of individual differences in the rate of change in skin electrical resistance. Further, since the learning effect becomes more remarkable as the number of times of use of the same user increases, there is an effect that the stress relieving effect of the user can be further enhanced.
