2. Description of the Related Art In motions such as walking and jogging, a pacemaker, an electronic metronome, or a portable audio device that emits an electronic sound at a constant period to keep the tempo of the motion has been used.
With these devices, it is generally difficult to adjust the pitch and frequency initially set during operation, so if the user's operation tempo changes, the audio device and the user's operation tempo will shift. The user sometimes felt uncomfortable and uncomfortable. Therefore, a device that changes the pitch, frequency, and the like of sound in accordance with the operation tempo of the user has been proposed.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the first invention will be described. The major feature of the health management system according to the first invention is that the state is evaluated by comparing the user's exercise amount or exercise index amount with the target exercise amount, and the operation instruction from the operation instruction means is adjusted based on the evaluation result. It is in. With such a configuration, it is possible to smoothly guide the user's exercise amount to the target exercise amount. In addition, in order to make the description easy to understand, the following description will be made using “exercise amount” as an example. In the case of “exercise index amount”, “exercise amount” may be read as “exercise index amount”.

FIG. 1 is a block diagram showing an example of the present invention. The biological information measured by the measuring means 1 worn by the user is sent to the calculating means 2 via a wireless or wired communication means. The biological information to be measured includes, for example, vibration, acceleration, electrocardiogram, blood pressure, body temperature, pulse, myoelectricity, perspiration, inclination, etc., and may be measured by combining one or two or more of these. . As means for measuring such biological information, a vibration sensor, an acceleration sensor, an electrocardiographic sensor, a blood pressure sensor, a body temperature sensor, a pulse sensor, a myoelectric sensor, a perspiration sensor, a tilt sensor, and the like can be used. It is preferable to use a vibration sensor, an acceleration sensor, or an electrocardiographic sensor because the mounting load is small and the size is small. In addition, the mounting location of these measuring means may be appropriately determined from the type of exercise equipment, the type of biological information, and the like.

The calculating means 2 calculates the amount of exercise from the measured biological information. For example, if the measured biological information is an electrocardiogram, it is possible to calculate how many calories are consumed as the amount of exercise from the heart rate, and it is also possible to calculate the product of the amplitude and the period as the amount of exercise index from the electrocardiogram waveform. FIG.
FIG. 2 is a block diagram showing an example of the embodiment. Using this calculating means 2, for example, the electrocardiographic waveform shown in FIG.
When the waveform processing is performed according to (details of the digital filter are shown in FIG. 10), an electrocardiographic waveform shown in FIG. 6 is obtained. The sum of the maximum value a ₁ ~a _n per unit time of the electrocardiographic waveform and the signal strength per unit time, the time interval _{(a 1 -a 2, a 3} -a 2, ··
) Is the signal pitch, and the product of the signal strength and the signal pitch is the motion index amount. The electrocardiographic waveforms in FIGS. 5 and 6 have a time width of 10 seconds at a frequency of 400 Hz.

Then, the state evaluation means 3 in FIG. 1 evaluates the state by comparing the calculated amount of exercise with the target amount of exercise. For example, when the biological information is an electrocardiogram, the state may be evaluated from the difference between the calculated exercise amount and the target exercise amount. That is, if the difference between the two is large, it is evaluated that the amount of exercise is insufficient or excessive. If the difference is small, it is evaluated that the amount of exercise is close to the target amount of exercise, and the operation instruction output from the feedback means 4 described below is adjusted. In addition, when the electrocardiogram is used as the biological information, since the electrocardiogram greatly fluctuates due to the physical condition of the user, in addition to the difference between the target exercise amount and the calculated exercise amount,
It is preferable to determine the rate of change of the amount of exercise and evaluate the state of the user. Otherwise, the operation may be overloaded or lightly loaded. In addition, the heart rate control in the vicinity of the target amount of exercise becomes easy when the change rate of the amount of exercise is considered.

FIG. 3 shows an example of the state evaluation means 3. When the amount of exercise calculated by the calculation means 2 is sent to the state evaluation means 3, first, the comparison unit 31 compares it with the target amount of exercise.
When the difference between the two is large, the multiplication coefficient for adjusting the output signal in the adjusting section 32 is increased. Conversely, when the difference is small, the multiplication coefficient is reduced. Although the value of the multiplication coefficient is not particularly limited, it is generally sufficient that the value of the multiplication coefficient is 0.5 to 2 in absolute value. The determined multiplication coefficient is sent to the feedback means 4.

Here, the target exercise amount may be appropriately determined by the user in consideration of the physical condition at that time. In this case, the target exercise amount is calculated by inputting the user's age and desired exercise intensity from the input means. It is preferable to do so.
For example, when measuring the heart rate as the biological information, the following formula (Carbonen) is calculated based on the user's age and desired exercise intensity input from the input means and the user's resting heart rate automatically measured by the device. May be used to calculate the target heart rate. If the purpose is to promote health, the exercise intensity is set to, for example, 0.5. Target heart rate = resting heart rate + {(220-age)-resting heart rate} x exercise intensity (where the exercise intensity is in the range of 0 to 1.0)

The feedback means 4 adjusts the operation instruction from the operation instruction means 5 based on the evaluation result obtained as described above. More specifically, as shown in FIG. 4, an operation instruction unit 5 multiplies an output signal for instructing the user to perform an operation by a multiplication coefficient determined by the state evaluation unit 4.
Send it to

The operation instructing means 5 is not particularly limited as long as it instructs the user to perform an operation. For example, a PCM sound source (Pulse Code Mod) similar to a blinking lamp or a heartbeat sound is used.
uleSound Source) or giving video to the user. Such an operation instruction to the user may be given explicitly or implicitly. As an example of the former, there is exemplified a method in which a sound of about 1 kHz to 3 kHz (a sound flowing when a test pattern is broadcast on a television) is emitted for about 0.3 seconds to prompt the user to perform an operation. Examples of the latter include a method of adjusting the playback speed of the music so that the user unconsciously tracks the speed, or a method of adjusting the pitch. When the playback speed is changed, if the pitch changes, the user will feel uncomfortable and will be given an explicit operation instruction, so if the operation instruction is implicit, only the playback speed or the pitch must be changed. There is. In addition, the user blinks multiple lamps with the song that the user likes,
By adjusting the blinking speed, the user's operation can be instructed implicitly.

By the way, even if the calculated exercise amount of the user reaches the target amount by the operation instruction from the operation instruction means, the exercise operation of the user is optimized and the apparent amount of exercise changes. However, a phenomenon in which the actual momentum decreases, a so-called steady state, may appear. For example, when the user's exercise amount is calculated by an acceleration sensor,
Although the calculated amount of exercise does not change, the heart rate may gradually decrease. In this state, the user cannot perform the target amount of exercise. Therefore, in such a case, it is preferable to prevent the optimization of the user's operation by changing the operation load of the user. Specifically, when exercising using an exercise equipment, the load of the exercise equipment is changed. For example, when a walking exercise is performed using a walking device, the inclination and walking speed of the walking device are changed. When the user does exercise without using exercise equipment, the operation load is changed explicitly or implicitly by the operation instruction means. In this way, the appearance of the steady state can be prevented or eliminated at an early stage.

Next, the second invention will be described. A major feature of the health care system according to the present invention is that the output of an output unit such as a home electric appliance is adjusted according to the state of the user without directly changing the setting by the user. As a result, it is possible to prevent the health damage of elderly people who are not good at handling electric devices.

FIG. 7 is a schematic diagram showing an example of the health management system of the present invention. The user wears the measuring means 1 for measuring the heart rate, and the measured heart rate is sent to the evaluation means 6. Here, the user's standard heart rate is compared with the measured heart rate, and if the measured heart rate is higher than the standard heart rate, the user is evaluated as being in an excited state (high body temperature). Conversely, if the measured heart rate is lower than the standard heart rate, the user is evaluated to be dormant (low body temperature). Then, based on the evaluation result, the feedback means 4 adjusts the set temperature of the air conditioner, which is the output means 7, to be lower in the excited state and higher in the dormant state. Further, the air volume and direction of the air conditioner may be adjusted.

The biological information measured here includes, in addition to the heart rate, for example, electrocardiogram, blood pressure, body temperature, myoelectricity, respiration, sweating, etc. One or two or more of these may be measured. I just need. A heart rate sensor, an electrocardiographic sensor, a blood pressure sensor, a body temperature sensor, a myoelectric sensor, a respiratory sensor, a perspiration sensor, or the like can be used for measuring such biological information.

As the output means, in addition to the air conditioner, home appliances such as lighting equipment and electric fans can be mentioned.

The evaluation of the state of the user by the evaluation means may be performed by, for example, evaluating whether the current state of the user is in comparison with the normal state of the user. Then, the output means is adjusted in proportion to the difference from the normal state. That is, the greater the difference from the normal state, the greater the output adjustment range of the output means.

Next, the third invention will be described. A major feature of the entertainment system according to the present invention is that the output of the output means is adjusted based on the current evaluation result of the user. As a result, an event can be generated at a time that is contrary to the user's expectation, and the surprise and excitement will not be reduced even for a user who has repeated similar experiences.

FIG. 8 is a block diagram showing an example of an entertainment system according to the present invention. A measuring means 1 for measuring a heart rate is attached to a user watching an image such as a movie.
The measured heart rate is sent to the evaluation means 6. Here, the user's standard heart rate is compared with the measured heart rate, and if the measured heart rate is equal to or higher than the standard heart rate,
Assessed to be nervous. Conversely, if the measured heart rate is less than or equal to the standard heart rate, the user is evaluated as being in a normal or relaxed state. Then, in the feedback means 4, a speaker or a headphone as the output means 7,
The video output device, the lighting device, the air conditioner, and the like are adjusted based on the evaluation result. For example, if the user is watching a horror movie, if the user's heart rate is above the standard heart rate and excited or nervous, postpone scary scenes,
When the heart rate falls below the standard heart rate, a scary scene (event) is generated. At this time, if the sound, lighting, vibration, wind, etc. are adjusted in accordance with the image, the user can be given a more realistic feeling. In this way, since the event occurs at a location unexpected to the user, the surprise and excitement of the user is further increased.

The biological information measured here includes, in addition to the heart rate, for example, electrocardiogram, blood pressure, body temperature, myoelectricity, respiration, and perspiration as described above, and one or two or more of these are measured. What is necessary is just to measure in combination. In addition, as a measuring means for measuring such biological information, a heart rate sensor, an electrocardiographic sensor, a blood pressure sensor, a body temperature sensor, a myoelectric sensor, a respiratory sensor, a perspiration sensor, or the like can be used as described above.

As the evaluation of the state of the user by the evaluation means, for example, it is sufficient to evaluate whether the current state is present as compared with the normal state of the user. That is, the higher the value is, the higher the excitement / tension state is, the higher the value is compared with the normal state, and the lower the value is, the more the state is relaxed.

Output means that can be used in the present invention include:
There is no particular limitation on the output means acting on the five members of the eyes, ears, nose, tongue, and skin, and examples thereof include a monitor / TV, speaker / headphone, lighting equipment, air conditioning equipment, and vibration equipment.
