CONSTITUTION:A first electrode 2 and a second electrode 3 are disposed on the top surface of a watch case 1. A time 5, an alarm time 6, and a relaxation degree graph 7 are shown on a liquid crystal display 4. Pushbuttons 8, 9 as external operation members are disposed on the side of the watch case 1 for setting the time and alarm time. Setting the alarm time to a required time by operating the pushbuttons 8, 9, an index finger is placed on the first and second electrodes 2, 3. The relaxation degree graph shows zero and the timer starts countdown. The relaxation degree graph moves to the negative side if the relaxation degree increases, and moves to the positive side if the awakening degree increases. When the remaining time becomes zero, a buzzer sounds to notify a user of the end of the countdown.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic timepiece having a biofeedback function that can detect electrical skin resistance and determine the relaxed state of the mind and body.

[Conventional technology]

Traditionally, changes in human emotion are measured by electrical skin resistance (hereinafter referred to as S) in the palm of the hand.
It is well known that this phenomenon appears as a change in R (referred to as R), and is used as the principle of the ancient (R) detector. SR has also come to be used as an index of the degree of relaxation in biofeedback (hereinafter referred to as BF) training, which is one type of training.

Furthermore, BP training has been found to be effective in improving concentration and self-control of stress, and its use not only in hospitals but also in the general public has attracted attention.

Figure 3 is a graph showing the relationship between SR and mental state.
The vertical axis shows electrical skin resistance, and the horizontal axis shows time. Period A
is in a resting state, and SR is almost stable at R. Period B is, for example, a time when mental arithmetic is being performed, and SR drops to R3. This is a phenomenon that generally occurs when some kind of physical or mental stress is applied. Period C is BF
This is the time when SR enters a state of relaxation, and SR gradually becomes high (relaxed state occurs for a period of time), and SR stabilizes at R8.

Period E is a period of returning from a relaxed state to an awake state, and gradually returns to a resting state.

BF devices are commercially available in installed models for use in hospitals and those that are small enough to be held in the palm of the hand, but as BF training becomes more widely applicable to the general public, small and portable devices are desired.

[Problem to be solved by the invention]

However, conventional devices are bulky (inconvenient to carry),
Furthermore, since the SR level differs from person to person, the volume for level adjustment must be adjusted for each person, which is inconvenient in use. Furthermore, because the conventional type is designed to be used under the guidance of a doctor or other instructor or with audio tapes, there are limitations on where it can be used, and when training for a set period of time, time is of concern. In some cases, the patient was unable to achieve deep relaxation, or even fell asleep in the early stages.

An object of the present invention is to provide an electronic watch with a biofeedback function that is convenient to carry and easy to use for time management.

[Means to solve the problem]

In an electronic watch having a time reference source, a frequency dividing circuit, an external operating means, and a time display means, a watch case provided with first and second electrodes, and a resistor for detecting the electrical resistance between the first and second electrodes. It is portable by providing a detection means, a resistance change calculation means for calculating a change in resistance based on a signal from the resistance change calculation means, and a resistance change display means for displaying a resistance change based on a signal from the resistance change calculation means. An electronic clock with biofeedback function has been realized.

Furthermore, it is preferable to have an additional function of notifying the end of biofeedback training for a certain period of time by setting a timer circuit and a buzzer that can be set by an external operating member.

2 is a basic block diagram of the first embodiment, and FIG. 4 is a detailed block diagram of the first embodiment.

First and second electrodes 2.3 are arranged on the upper surface of the watch case 1 made of plastic.

The liquid crystal display device 4 is configured to display a time 5, a timer time 6, and a relaxation degree graph 7. Also, watch case 1
A button 8.9, which is an external operation member for setting the time and timer, is provided on the side surface of the watch.

How to use it is to set the timer time 6 to a desired time by operating the button 8.9, and place the index finger of your hand on the first and second electrodes. The relaxation graph 7 displays O and the timer starts counting down. Depending on the state of relaxation, the relaxation degree graph 7 moves in the negative direction as the relaxation deepens, and moves in the positive direction as the arousal increases. When the remaining time on the timer reaches O, a buzzer sounds to notify the user of the end.

Next, a basic block diagram of the electronic timepiece of this embodiment will be explained based on FIG. Time reference source 11 consisting of a crystal oscillator circuit
The frequency of the signal is divided by the frequency dividing circuit 12, and the time is displayed by the time display means 16. 1st. Electrode 1 consisting of a second electrode
When a finger touches 4, the electrical resistance of the skin is detected by the resistance detection means 15.
The resistance change calculation means calculates the change in resistance, and the resistance change display means 17 displays the resistance change=relaxation degree. In addition, as described above (the time display means 13 is controlled by the external operation member 18).
and timer circuit 19 is set.

Next, a detailed block diagram of this embodiment will be explained based on FIG. A signal from the electrode 14 constituted by the first electrode 2 and the second electrode 3 is detected as a voltage by the resistance dividing section of the resistance detection means 15, and the voltage is converted into a frequency by the A/D conversion circuit 20.

The resistance change calculation means 16 includes a comparison circuit 21 that compares a preset voltage with the voltage output from the resistance detection means 15.
and an arithmetic control circuit 22. If the finger is not in contact with the electrode 14, the output of the comparator circuit 21 is H, and if the finger is in contact, the output of the comparator circuit 21 is L, and the finger is in contact with the electrode 14. It outputs to the arithmetic control circuit 22 only when it detects that it has been performed. Thereafter, the arithmetic control circuit 22 issues a conversion start signal to the A-D converter circuit 20, and when the input from the A-D converter circuit 20 becomes almost stable, that value is recorded as the reference resistance value at rest. The resistance change is calculated and the result is sent to the resistance change display means 17. Therefore, the user does not need to adjust the RS level using d-lume or the like.

The time display means 16 and the resistance change display means 17 are used in common, and the display control circuit 26 receives the clock from the frequency dividing circuit 12 to display the time on the liquid crystal display device 24, and the display control circuit 26 receives the clock from the frequency dividing circuit 12 and displays the time on the liquid crystal display device 24. In response to the signal of the calculation result of the change in resistance value, the change in resistance value is displayed on the liquid crystal display device 24, and the change in resistance value is converted into a change in frequency and transmitted to the buzzer drive circuit 25 to drive the buzzer 26.

Therefore, the user can see the change in resistance on the graph on the liquid crystal display 24, or hear it as a change in the frequency of the buzzer sound. sets the time of the timer circuit 19 and the display control circuit 26, and when the timer circuit 19 reaches 0 after a predetermined time has elapsed, it sends a signal to the buzzer drive circuit 25 and causes the buzzer 26 to emit a final buzzer sound.
