Preferably, the antistatic composition may include 40 to 80 parts by weight of the polysiloxane represented by Formula 2, 30 to 50 parts by weight of the conductive filler, and 5 to 10 parts by weight of the graphite based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect of critical significance is expressed as an antistatic synergistic effect due to the interaction of each component, and when it is out of the above range, the synergistic effect is rapidly reduced or almost absent.

More preferably, the viscosity of the antistatic composition is 1,200 to 1,500 cP, and when the viscosity is less than 1,200 cP, there is a problem that it is not easy to form an antistatic layer because it flows down during coating on one surface, and when it exceeds 1,500 cP There is a problem in that it is not easy to form a uniform antistatic layer.

[Preparation Example: Preparation of Coating Layer]

1. Preparation of coating composition

An antistatic composition was prepared by mixing polysiloxane represented by the following Chemical Formula 3, a conductive filler, and graphite in an organic solvent in which toluene and phenol were mixed in a weight ratio of 1:1:

[Formula 3]

Here, m is an integer from 10 to 30, and p is an integer from 3 to 5.

A more specific composition of the antistatic composition is shown in Table 1 below.

DY1 DY2 DY3 DY4 DY5 DY6 organic solvent 100 100 100 100 100 100 polysiloxane 20 30 40 60 80 100 alumina 10 20 30 40 50 60 graphite One 3 5 7 10 15

(unit parts by weight) The alumina has a particle diameter of 30 to 50 µm. Preparation of protective layer

An antistatic layer was formed by applying the antistatic composition of HS 1 to HS 6 on one surface of the base layer prepared using a polyamide resin, and then thermally curing the composition.

[Experimental example: Antistatic effect test]

1. Viscosity Measurement

Before forming the antistatic layer on one surface of the polyamide base layer, the viscosity of the antistatic composition was measured. Viscosity was measured using a rheometer (Rheometer, Compac-100, Sun Sci. Co., Japan). The viscosity measurement results are shown in Table 2 below.

DY1 DY2 DY3 DY4 DY5 DY6 Viscosity (cP) 620 800 1010 1400 1950 2400

2. Measurement of Surface Electrical Resistance For the protective layer in which the antistatic layer of DY 1 to DY 6 is formed on one surface of the polyamide base layer, use a Resistance Meter SIMCO resistor ST-4 (25°C, 50% relative humidity) for the surface electrical resistance was measured. As a comparative example, the surface electrical resistance of the polyamide base layer on which the antistatic layer was not formed was also measured.

comparative example DY1 DY2 DY3 DY4 DY5 DY6 Surface electrical resistance (Ω/cm ² ) 7.4×10 ¹¹ to 1.6×10 ¹² 6.4×10 ⁹ to 1.4×10 ¹⁰ 1.4×10 ⁹ to 1.6×10 ¹⁰ 7.2×10 ⁸ to 6.1×10 ⁹ 4.4×10 ⁷ to 2.1×10 ⁸ 6.5×10 ⁷ to 4.5×10 ⁸ 5.8×10 ⁸ to 7.8×10 ⁸

According to Table 3, compared to the comparative example in which the antistatic layer is not formed, since the surface electrical resistance of DY 1 to DY 6 is low, the electrical conductivity is excellent, and it can be confirmed that an excellent antistatic effect is exhibited. Evaluation of surface appearance

Due to the difference in viscosity of the antistatic composition, after the coating layer was prepared, a sensory evaluation was performed on whether a uniform surface was formed. Whether or not a uniform coating layer was formed was evaluated, and evaluation was performed according to the following criteria.

○: uniform coating layer formation

×: Formation of a non-uniform coating layer

DY1 DY2 DY3 DY4 DY5 DY6 sensory evaluation × × ○ ○ ○ ×

When the coating layer is formed, if the viscosity is less than a certain level, flow occurs on the surface of the polyamide, and formation of a uniform coating layer is difficult in many cases. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition, making it impossible to form a uniform coating layer. According to one disclosure, the wearable keyboard 100 includes 10 pressure-sensitive sensors ( 101) may be included. According to one disclosure, the ten pressure-sensitive sensors 101 may include unique identification information corresponding to each finger. Accordingly, when a pressure equal to or greater than a threshold value is sensed, the wearable keyboard 100 may determine a preliminary output value by determining a finger at which a signal is sensed.

According to one disclosure, the flex sensor 111 may be installed to correspond to the first joint to the third joint of the user's finger in order to measure the degree of bending of the user's finger. According to one disclosure, the flex sensor 111 may be attached to the glove only at both ends and the middle portion of the flex sensor 111 for the convenience of movement of the user's finger.

According to one disclosure, the gyro sensor 103 may be installed on the index finger of both hands of the user to determine the x-axis position to which the index finger is input. The gyro sensor 103 measures the direction information of the hand. Additionally, the wearable keyboard 100 may include an acceleration sensor for measuring acceleration information, a gyro sensor for measuring rotation information of the hand, and a geomagnetic sensor for measuring the direction of the geomagnetism. The measured value of the gyro sensor 103 may be provided to an inertial measurement unit (IMU). The inertial measurement device may be provided in the form of one integrated unit consisting of a total of three sensors: an accelerometer capable of measuring movement inertia, a gyrometer capable of measuring rotational inertia, and a magnetic field capable of measuring an azimuth. Rotation information on three axes, ie, pitch, roll, and yaw, may be obtained by using the measured values of the gyroscope and the magnetic field.

According to one disclosure, the processor 115 sets the hysteresis parameter range to less than 20% in order to reduce the error rate of the user input signal recognized by the pressure-sensitive sensor 101 , the gyro sensor 103 and the flex sensor 111 . can

7 is a diagram for explaining an operation of recognizing first sensed data in a wearable keyboard, which is an input device of the present invention.

In FIG. 7 , L1, L2, and L3 refer to graphs representing increases and decreases in pressure when the user intentionally applies forces of different magnitudes to the first to third input levels. In other words, it refers to a case in which the force is applied to a weak level, a medium level, and a strong level, respectively. By the start, it can be confirmed that the force applied to the floor surface according to the user's input starts to increase rapidly at about 40-50 ms, peaks at about 80-100 ms, and then ends at about 110-120 ms.

Preferably, in consideration of the experimental results as described above, the recognition time is preferably set to a time of 50 ms to 150 ms based on the time when the pressure of a predetermined size or more is started to be input from the pressure-sensitive sensor unit. And it is more preferably set to a time of 70 ms to 110 ms. Here, if a time less than 50 ms or greater than 150 ms is set as the recognition time, it can be seen that the magnitude of the pressure applied according to the input applied to the wearable keyboard cannot be measured correctly.

The recognition time may be set based on a time when the pressure has a maximum value for a predetermined time from the time when the pressure of a predetermined level or more is started to be input from the pressure-sensitive sensor 101 . Preferably, the time when the pressure has a maximum value may be the recognition time.

Here, the wearable keyboard 100 may analyze the change in the magnitude of the input pressure without setting a fixed recognition time, and select the input level based on the magnitude of the pressure at the point in time when the pressure has a maximum value. In this way, when the maximum pressure value is used, there is an effect that the user can more accurately recognize the amount of pressure intended by the user and determine the input level accordingly.

To this end, the wearable keyboard 100 may store the amount of pressure input from the pressure-sensitive sensor 101 over time according to time, and determine the input level using the largest pressure among the stored pressures.

However, in the case of using the maximum value as described above, memory is required to identify the maximum value and power for signal processing may be consumed. Therefore, the previously set recognition time may be used in order to save memory and power. When the preset recognition time is used as described above, since the input level can be determined using only the pressure input at the corresponding recognition time, memory can be saved and power consumed for signal processing can be minimized.

According to another embodiment, the wearable keyboard 100 may set the most suitable threshold for each user according to the user's input in order to recognize the input level.

According to one disclosure, the threshold value may be selected and set according to a user's selection input from among a plurality of values presented to the user by a setting program driven by the wearable keyboard 100 . For example, the designer of the setting program measures the degree of force applied when inputting the wearable keyboard 100 to the users having each age, gender, and physical condition according to the statistics of the experiment result for each age, gender, and physical condition. A threshold value most suitable for a user having a condition may be determined, and accordingly, a threshold value for each user profile may be set in a setting program according to the user's age, gender, and physical condition. For example, in a setting program driven by the wearable keyboard 100, a threshold value is preset for each user profile, and a preset threshold value can be used for the selected profile by receiving a user's selection input for the user profile. . For example, if the setting program pre-stores a threshold value corresponding to a user profile for each age and age group, and the user selects a female user profile or a user profile in her twenties, the wearable keyboard 100 displays the user profile of a woman in her twenties. A preset threshold value (first threshold: 0.5N, second threshold 3N) may be used.

Alternatively, the threshold value may be set in such a way that the wearable keyboard 100 uses pressure generated according to each user's touch input. Here, the wearable keyboard 100 may set a predetermined threshold as a comparison standard to select the input level using the pressure input from the pressure-sensitive sensor 101 .

The inorganic particles may be selected from the group consisting of silica, alumina, and mixtures thereof.

[Experimental example]

1. Evaluation of surface appearance

Due to the difference in viscosity of the coating composition, after the coating layer 1322 was prepared, a sensory evaluation was performed as to whether a uniform surface was formed. Whether or not a uniform coating layer 1322 was formed was evaluated, and evaluation was performed according to the following criteria.

When the coating layer 1322 is formed, if the viscosity is less than a certain viscosity, a flow occurs on the surface of the lens 1321 , and after the curing process, it is difficult to form the uniform coating layer 1322 in many cases. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition to form a uniform coating layer 1322 .

2. Measurement of water repellency angle

After forming the coating layer 1322 on the surface of the lens 1321, the results of measuring the water repellency angle are shown in Table 3 below.

As shown in Table 3, after forming the coating layer 1322 using the coating composition of TX1 to TX5, the result of measuring the contact angle was confirmed. For TX1 and TX5, the receding contact angle was measured to be less than 10 degrees. That is, when it is out of the optimal range for preparing the coating composition, it was confirmed that the phenomenon of pinning water droplets occurs. On the other hand, it was confirmed that the peening phenomenon did not occur in TX2 to 4, thereby exhibiting an excellent waterproof effect.

3. Pollution resistance evaluation

The lens 1321 having the coating layer 1322 formed according to the embodiment on the outside of the facility was attached to the model camera, and exposed to the driving environment on a general road for 4 days. As the comparative example (Con), the same lens 1321 on which the coating layer 1322 was not formed was used, and in each embodiment, the model camera was attached to the same position of the vehicle.

Thereafter, the degree of contamination of the lens 1321 before and after the experiment was evaluated as related, and for objective comparison, the result was evaluated as an index of 1 to 10 in comparison with the comparative example in which the coating layer 1322 was not formed. shown in In the following index, the lower the number, the better the stain resistance.

Referring to Table 4, when the coating layer 1322 is formed on the lens 1321, the high contamination resistance is easily analyzed for a long period of time even when the lens 1321 is exposed to the outside while the camera is installed in an external environment. It can be seen that image data can be collected. In particular, in the case of TX2 to TX4, it can be seen that the stain resistance by the coating layer 1322 is very excellent.
