Description

[0001]
[Industrial application fields]
The present invention relates to a control method for various devices such as home appliances, and more particularly to a novel control method that takes into account the feeling of the device user.
[0002]
[Prior art]
Conventionally, in home appliances such as an air conditioner and a television receiver, as shown in FIG. 3, an input amount X is determined based on a parameter set by a user's operation, and the input amount X A faithful control method in which a control amount Y for the device is calculated by performing arithmetic processing using the transfer function (5) has been adopted.
For example, in an air conditioner, faithful temperature control is performed with a temperature adjustment value set by a user's operation as a target.
In a television receiver, faithful volume control is performed with a target volume adjustment value set by a user operation.
Further, in a three-dimensional television receiver, faithful three-dimensionality control is performed with an adjustment value of the three-dimensionality (three-dimensional pop-out amount) set by a user operation as a target.
[0003]
[Problems to be solved by the invention]
However, the faithful control method based on the conventional setting parameters has a problem that a control state that the user feels comfortable cannot always be obtained.
For example, in temperature control of an air conditioner, the target temperature desired by the user is not always the set temperature at which the user actually feels comfortable.
In a television receiver, the sound volume that the user has determined to be appropriate may be an excessive sound volume that causes stress to the user.
Further, in the three-dimensional television receiver, the fatigue level of the user may be further increased by the three-dimensionality set by the fatigued user.
[0004]
An object of the present invention is to obtain an optimal control state that always feels comfortable for a user by imitating a value judgment and control method based on a sense performed in the brain when a human acts. It is to provide a device control method that can be used.
[0005]
[Means for solving the problems]
A device control apparatus according to the present invention performs a calculation process using a predetermined transfer function on an input amount for controlling a control target device, calculates a control amount according to the input amount, and supplies the control amount to the control target device in a detecting means for detecting a biological signal of the user of the control target device, an estimating means based on the detected biological signal, the user estimates the sense to receive in use of the control target device, Based on the user's feeling estimated by the estimation means, an appropriate sub-transfer function is selected from a plurality of different types of sub-transfer functions that can be selected, and the input function is calculated by the transfer function. determining the effect of the control amount on the sense of the user, the adjustment value calculated by the sub transfer function the selection according to the result of the determination by adding to the control amount, and comfortable feeling for the user And comprising an adjusting means for obtaining a new control amount is.
[0006]
Here, specifically, the biological signal is skin temperature, an electrocardiogram signal, and / or an electroencephalogram, and the sensations to be estimated based on the biological signal are fatigue, comfort, tension, and / or Or the degree of excitement.
[0007]
[Action and effect]
If the user of the device to be controlled feels fatigue or stress when using the device, those sensations should be manifested as changes in skin temperature, ECG signals, or biological signals such as brain waves. become.
Therefore, it is possible to detect a biological signal of the device user and estimate a sense felt by the user based on the biological signal.
Then, by adjusting the transfer function according to the estimated sense and calculating the control amount for the target device, it is possible to realize device control that the user always feels comfortable.
[0008]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the device control system of the present invention has a main transfer function (1) similar to the conventional transfer function, and a plurality of sub-transfer functions (4) in parallel with the main transfer function (1). These sub-transfer functions (4) are switched by a selector (3).
[0009]
The selector (3) has a plurality of output terminals connected to each sub-transfer function (4) and an OFF terminal not connected to any sub-transfer function. Terminal switching control is performed from the sensory estimation circuit (2). The automatic selection signal or the manual selection signal.
The sensation estimation circuit (2) estimates sensations such as fatigue, comfort, tension, and excitement based on biological signals such as skin temperature, electrocardiogram signals, and brain waves. For example, it is possible to estimate the degree of fatigue based on the amount of decrease in skin temperature of the peripheral part such as the nose.
[0010]
The plurality of sub-transfer functions (4) are transfer functions for determining the influence of the control amount by the input amount based on the setting parameter on the operator's feeling and calculating the adjustment amount f with respect to the control amount. As the operator's feeling, the fatigue level is adjusted by the first transfer function G1, the comfort level is adjusted by the second transfer function G2, the tension level is adjusted by the third transfer function G3, and the excitement level is adjusted by the transfer function G4.
[0011]
In the above control method, the input amount X is determined based on the parameter set by the user's operation, and the input amount X is subjected to arithmetic processing by the main transfer function (1). Calculation processing is performed by one auxiliary transfer function (4) selected by the selector (3), and the adjustment amount f is calculated.
[0012]
Then, the control amount e obtained through the arithmetic processing by the sub-transfer function (4) is subtracted from the control amount e obtained through the arithmetic processing by the main transfer function G0, so that the control amount Y for the control target device is obtained. It is calculated.
[0013]
Here, the first transfer function G1 for the degree of fatigue is illustrated in FIG. 2 (a), and the fourth transfer function G4 for the degree of excitement is illustrated in FIG. 2 (b).
In FIG. 2 (a), in the fatigued state, if the input amount, for example, the stereoscopic setting value in a stereoscopic television receiver exceeds a certain value, it becomes very easy to get tired. Is set to a large value to suppress an increase in the control amount.
In FIG. 2B, when the input amount is small in the excitement state, the adjustment amount is increased in the negative direction according to the degree of excitement, and the control amount (three-dimensional pop-out amount) is increased to Although the effect of the image is increased, if the input amount exceeds a certain value, no further three-dimensional effect is required, so the adjustment amount is set to zero and control is performed only by the main transfer function G0.
[0014]
According to the device control system that takes into account the sensation of the present invention, device control that the user always feels comfortable is automatically performed regardless of the device operation amount of the user. Therefore, fatigue associated with the user's use of the device is prevented.
