In addition, wearable wearable devices must use a new product in the form of a cloth, which is specialized in clothes, even if one of the simple switches is taken into account in consideration of the wearer's comfort.

However, in the related art, a control device using a film type device is mostly used for controlling a wearable wearable device, and there is an example of a control device using some textile materials. However, this is also because drape property is poor There is a problem that the wear quality is deteriorated because of a feeling of heterogeneity due to the attachment type.

In addition, the conventional control device for controlling the wearable wearable device has a problem in that unintended operation occurs due to contact by objects other than control by the user's body (for example, touch, etc.) There is a problem in that the input for controlling the user can not be accurately detected, for example, a malfunction occurs due to a force (for example, bending of the fabric).

In addition, since the fabric manufacturing process is not continuously performed, the integrity of the product is lowered and the cost of the applied product is increased.

In the description of each component, the first layer 110 may sense the touch of the user, and may include conductive fibers and insulating fibers for this purpose.

Here, the conductive fibers and the insulating fibers may be integrated through a weaving or knitting method. According to an embodiment, as shown in FIG. 1, the conductive fibers and the insulating fibers are alternately formed in a linear form And may be formed in other patterns such as a zigzag pattern.

When an input means such as a user's finger touches a plurality of conductive fibers of the first layer 110, a user's touch can be sensed based on a change in capacitance between the conductive fibers.

Also, the conductive fibers of the first layer 110 may be connected to the circuitry 140 via leads. That is, the plurality of conductive fibers formed on the first layer 110 may be connected to the circuit unit 140 by a single lead wire.

Meanwhile, the second layer 120 may be positioned below the first layer 110, and may sense the pressure of the user's touch applied to the first layer 110.

To this end, the second layer 120 may comprise a piezo resistive type fabric.

Here, the piezo resistive type fabric may include metallic particles such as carbon nanotubes (CNT), silver (Ag), or metallic fibers.

The second layer 120 can sense the resistance change caused by the change of the behavior of the fabric of the second layer 120 due to the pressure of the user's touch applied to the first layer 110.

The second layer 120 has a resistance value of a predetermined magnitude in a state where an external force (touch of the user) is not applied, and if the external force is applied, the resistance value decreases or increases according to the intensity of the external force. So that not only the intensity of the external force but also the position where the external force is applied can be detected at the same time.

Meanwhile, the third layer 130 may be positioned below the second layer 120, and may be an electrode part fabric including conductive fibers.

Meanwhile, the circuit unit 140 may change the capacitance between the plurality of conductive fibers due to the touch of the user input through the first layer 110 and the pressure of the user's touch sensed through the second layer 120 It is possible to detect at least one of the touch and the pressure intensity and to detect the occurrence position thereof.

For this purpose, the circuit unit 140 may set a predetermined error range, determine that an electric signal having a frequency within an error range is appropriate, and determine whether the electric signal is suitable only based on the frequency of the electric signal, You may.

That is, by calculating whether the user touches only the electric signal having the set frequency and the intensity of the position and the pressure of the electric signal, the physical force that may occur in the clothes, such as the bending of the fabric, It is possible to prevent a malfunction from occurring.

For reference, if the intensity of the pressure is higher than a specific value, the input may be judged to be due to the user's touch.

In addition, the circuit unit 140 may change the resistance of the second layer 120 due to the resistance change sensed by the second layer 120, that is, the pressure due to the touch of the user applied to the first layer 110 (Pressure intensity) of the user's touch based on the resistance change occurring while the user changes the touch position, thereby determining the contact position of the user.

The circuit unit 140 may be connected to a DB including a touch position and a pressure based on the capacitance change and the resistance change, and a corresponding control command.

When the touch of the user is input to the first layer 110, the circuit unit 140 senses a change in capacitance between the plurality of conductive fibers and a change in resistance occurring in the second layer 120 due to a pressure caused by the touch of the user And extracts a corresponding control command from the DB to control the actuator connected to the circuit unit 140.

Here, the second layer 220, the third layer 230, and the circuit unit 240 among the components of the wearable control apparatus 200 may be the same as the wearable control apparatus 100 shown in FIG.

The first layer 210 may be a textile or a textile-type element such as a knitted fabric manufactured by a method of forming a conductive fiber on a dielectric material in the form of a capacitor using an embroidery process.

First, the wearable control apparatus 100 generates an electric signal having a specific frequency in the first layer 110 and the third layer 130 (S301).

If a plurality of conductive fibers of the first layer 110 are touched by a user's touch after step S301, the wearable control device 100 uses the change in capacitance between the plurality of conductive fibers, (S302).

After S302, the wearable control apparatus 100 senses the pressure of the user's touch based on the resistance change sensed through the second layer 120 due to the contact pressure of the user (S303).

For reference, it is explained that S303 is performed after S302, but S302 and S303 may be performed simultaneously.
