Description

SYSTEM AND METHOD FOR GUIDING PATH TO SHELTER IN DISASTER STATE

The present invention relates to a vehicle route guidance system and method from a disaster situation to an shelter. More particularly, it relates to a system and method capable of guiding a vehicle route so that the vehicle can be safely driven from a disaster situation to an evacuation shelter based on road condition information obtained through a plurality of entities.

An automobile may be classified into an internal combustion engine automobile, an external combustion engine automobile, a gas turbine automobile, an electric vehicle, or the like, according to a type of a prime mover used.

Also, in general, a navigation terminal is a device that provides a user's location and route guidance from a destination to a destination, and includes a vehicle, a ship, an air, and a portable navigation device.

Among them, the vehicle navigation terminal is installed in the vehicle or installed so that it can be mounted/detached, and the location of the moving object, road information, route information, and various additional information related to the location (danger area, accident-prone area, enforcement section, and surrounding facilities) related information, etc.) so that the user can arrive at the destination more quickly and safely.

In addition, with the rapid development of portable terminal devices such as smartphones in recent years, if an application including a navigation function is installed, the smartphone can be used in the same way as navigation.

Natural disasters or natural disasters are natural disasters such as storms, floods, tsunamis, earthquakes, and landslides, including death, loss of life, property, and damage to living things. said to be greatly affected. In particular, a natural disaster related to driving of a vehicle may be an earthquake.

In general, an earthquake is a vibration of the earth generated by the propagation of seismic waves from an elastic energy source. The magnitude of earthquakes varies from very small earthquakes detected only with sensitive seismometers to large-scale earthquakes that cause great damage to a wide area.

Thousands of earthquakes occur on Earth every day worldwide, and most earthquakes are caused by large internal forces acting on the movement of continents, the expansion of the sea floor, and the formation of mountain ranges over a long period of time.

Over the past 50 years, there have been about 500 thousand earthquakes with a magnitude of 7 or greater in various parts of the world, and the damage from earthquakes is increasing. For example, on August 15, 2007, the 'Great Peruvian Earthquake' with a magnitude of 8.0 occurred in Richter, on May 12, 2008, a "Great Sichuan Earthquake with a magnitude of 8.0 in Richter occurred," and on February 27, 2010, a "Great Earthquake in Chile" with a magnitude of 8.8 in Richter occurred. On March 11, 2011, a 'Great Tohoku Earthquake' with a magnitude of 9.1 in Richter occurred, and on April 25, 2015, a 'Great Earthquake in Nepal' with a magnitude of 7.8 in Richter occurred. In Korea, there have been no large-scale earthquakes in the past, but recently, on September 12, 2016, a 5.8 magnitude earthquake in Gyeongju, Korea and a 5.4 Richter earthquake in Pohang, Korea occurred on November 15, 2017. For this reason, interest in technology for detecting earthquakes and warning earthquakes in Korea is increasing.

In the event of an earthquake, the current level is to simply alert whether an earthquake has occurred through a mobile phone or speaker and transmit the address of a nearby shelter. As an example, according to the inventor of "Earthquake warning system and earthquake warning method using an application" described in Korea Patent Publication No. 10-1544200 (registration on Aug. 06, 2015), when an earthquake occurs, an earthquake warning is provided by a portable terminal within a predetermined range. is doing uniformly.

However, if an earthquake warning is issued uniformly in this way, people unfamiliar with earthquakes will be very confused when they hear the earthquake warning, and the probability that they will not be able to evacuate the earthquake appropriately may be very high. For this reason, there is a problem that many people may be damaged by an earthquake even when an earthquake warning has been issued.

In particular, in the case of people riding in a vehicle, there is a need for an invention for using a vehicle to quickly move to an evacuation center in preparation for a natural disaster such as an earthquake.

In the present application, terms such as “comprises” or “have” are intended to designate that a feature, number, step, operation, component, part, or combination thereof described in the specification exists, but one or more other features It should be understood that this does not preclude the existence or addition of numbers, steps, operations, components, parts, or combinations thereof.

Hereinafter, a detailed description will be given of a vehicle driving route guidance system in a disaster situation according to a first preferred embodiment of the present invention based on the above-described contents.

FIG. 1 is a view showing a vehicle driving route guidance system according to the present invention, and FIG. 2 is a view showing that a plurality of sensors according to the present invention are installed on a bump on a road.

Referring to FIG. 1 , a system according to the present invention may include a plurality of sensors 200 , an input device 100 , a display device 410 , and a server 500 . In addition, the system according to the present invention may include a navigation device 400 including a display device 410 . In this case, the navigation device 400 may be a portable terminal such as a smart phone in which a navigation application is installed.

1 , a system according to the present invention may be a system for guiding a vehicle driving route in a disaster situation. In the present invention, the plurality of sensors 200 may be installed in advance around the road to detect the first road condition information. The first road condition information may include all information detected by the plurality of sensors 200 . The first road condition information according to the type of sensor will be described later.

In the input device 100 according to the present invention, the second road condition information may be input by the driver. The input device 100 according to the present invention may be a wearable keyboard 100 to be described later. Details of the input device 100 according to the present invention will be described later.

Preferably, the second road condition information may be all information on the road condition input by the driver. The second road condition information may be collected in a form in which the driver answers a pre-prepared question and answer sheet.

As an example, the display device 410 provided to the driver may display the following prepared questions.

(1) Is there any damage to the current road?

(2) If the road is damaged, can it be driven by vehicle?

(3) Is the road you are currently driving on occupied by people?

(4) If the current road is occupied, can it be driven by vehicle?

In this way, the driver can focus on asking whether the vehicle is drivable on the currently driving road and collect information on the question.

The driver may write answers to the above questions by using a pre-prepared input device (wearable keyboard) 100 . In this way, big data can be formed through more specific feedback in an emergency situation. In the case of input by voice, if an error occurs in the process of recognizing the voice content, a fatal situation may occur in an emergency situation, so it is necessary to apply caution.

Referring to FIG. 2 , at least one of the plurality of sensors 200 may be installed inside a speed bump 700 on a road. As such, by being installed inside the speed bump 700 , it is possible to minimize damage or failure of the sensor due to the normal driving of the vehicle. The plurality of sensors 200 are not normally used, but may be activated after receiving a trigger message from the server 500 when an emergency situation such as a disaster situation occurs. After transmitting the trigger message, the server 500 may determine that a sensor without a response is malfunctioning.

Referring to FIG. 1 , the server 500 may further receive third road condition information from the plurality of vehicles 300 . In this case, the third road condition information may help to indirectly infer the road condition.

Preferably, for example, after a disaster occurs, it may be assumed that the vehicles 310 and 320 abruptly stop driving while driving through a specific route. When the signal for the corresponding vehicle 310 or 320 is interrupted, the server 500 may define a path traveled by the corresponding vehicle 310 or 320 as an unsafe route. As such, the vehicles 310 and 320 on a specific path stop running or communication with the vehicle is lost, and as the number of these vehicles 310 and 320 increases, the server 500 defines the specific path as unsafe. can

In addition, the third road condition information may be road condition information obtained through a camera, radar, lidar, etc. provided in the vehicle. In the case of an autonomous vehicle or a semi-autonomous vehicle, various sensing devices may be included to determine a situation on the road. Such a sensing device may detect a situation on the road in more detail. Accordingly, the server 500 may receive information on the road condition through a sensing device provided in the vehicle.

According to FIG. 2 , the plurality of sensors 200 according to the present invention may include a pressure sensor 210 , a gyro sensor 220 , an immersion sensor 230 , and a camera 240 . The pressure sensor 210 may detect an external force applied to the road. Accordingly, the pressure sensor 210 detects an external force applied to the road due to an earthquake or the like, and the server 500 may acquire information on the safety level of the road and whether there is damage or the like based thereon.

The gyro sensor 220 may detect the shaking of the road. When the road shakes more than a preset value due to an earthquake, etc., it may be determined that the road is not safe or has a high possibility of being damaged.

The submersion sensor 230 may detect whether the road is submerged. A tsunami is more likely to occur if the epicenter of an earthquake is near the sea. In particular, in the case of coastal roads, it will be necessary to judge the safety level due to tsunami. Accordingly, when the submersion sensor 230 is provided inside the bump 700 and it is determined that the road is flooded by a preset height, it may be determined that the corresponding road is not safe or is highly likely to be damaged.

The camera 240 may be installed to be spaced apart from the road by a certain height. By having a certain height, the camera 240 can capture more road conditions. The occupancy state of the road, whether it is damaged, etc. may be determined through the camera 240 . The occupancy state of the road used in the present invention is a state in which the road is occupied by vehicles or people who are evacuating, and thus may mean a state in which it is difficult for the vehicle to travel.

In this way, the server 500 may receive road condition information from a plurality of subjects, and obtain a recommended route to an evacuation shelter by synthesizing the information. The server 500 may receive the driver's current location information, and may receive location information on a point where a disaster such as an earthquake occurs. The server 500 may generate a list of shelters that the driver can reach by driving the vehicle, based on the driver's location information and location information on the disaster occurrence point. The shelter list may include a plurality of shelters within a predetermined distance from the driver.

The server 500 may obtain route information for each of a plurality of shelters included in the shelter list. The server 500 extracts a road corresponding to the route information, and obtains a recommended route among the route information based on the extracted road information obtained from a plurality of sensors 200 around the road and a driver around the road. have. The recommended route may be a route that can reach an evacuation center safely and quickly among the route information.

The server 500 may obtain a degree of safety for the route information, and the server 500 may select a route having the highest degree of safety as a recommended route. Also, the server 500 may select a recommended route in a way that excludes a road in which an event detected by a plurality of subjects exists among roads corresponding to the route information.

According to one disclosure, the wearable keyboard 100 may be manufactured in the form of a pair of gloves. According to one disclosure, the wearable keyboard 100 is a device for performing input by being worn on the user's hand, and in particular, refers to a keyboard without a keyboard. According to one disclosure, the wearable keyboard 100 may recognize a user's hand motion through a sensor and transmit an output value of recognizing a character meaning a hand motion to the external device 600 using a wireless communication module.

According to one disclosure, the wearable keyboard 100 determines an input signal for inputting the virtual QWERTY keyboard from the first sensing data obtained from the pressure-sensitive sensor 101 , and virtual from the second sensing data obtained from the flex sensor 111 . It determines the position at which the input signal is detected in the QWERTY keyboard, and generates an output signal based on the result of determining the position of the input signal input from the index finger from the third sensing data obtained from the gyro sensor 103, and the communication module output signal can be transmitted to an external device.

According to one disclosure, the external device 600 includes a display capable of displaying data input from the outside through a communication module, and includes a notebook PC, a desktop PC, an MP3 player, a Portable Multimedia Player (PMP), and a Personal Digital Assistant (PDA). , it is obvious that it can be applied to all information and communication devices and multimedia devices such as tablet PCs, mobile phones, smart phones, etc. and their applications.

According to one disclosure, the wearable keyboard 100 and the external device 600 may be classified into a master terminal and a slave terminal according to who serves as a host or an access point. In other words, a terminal that generates an identifier, that is, an SSID (Service Set Identifier) for pairing and accepts pairing becomes a master, and a terminal that requests pairing from such a master terminal becomes a slave. Also, in the present invention, a terminal may be a master or a slave. In addition, in the present invention, the terminal may download and install an application for performing such a pairing function from an online market. In addition, in the present invention, the terminal may receive and use an application from the cloud server 500 that provides a cloud computing service.

According to one disclosure, the wearable keyboard 100 may recognize a user's hand gesture using at least three types of sensors. More specifically, the wearable keyboard 100 uses the pressure sensor 101, the flex sensor 111, and the gyro sensor 103 to recognize the user's hand gesture, and from the recognized hand gesture, the user wants to input the character, etc. as an output value. may be transmitted to device 600 .

According to one disclosure, the pressure-sensitive sensor 101 may be installed to correspond to the positions of all finger tips of the user, and may determine whether the user inputs the virtual keyboard. When a pressure equal to or greater than a predetermined threshold is input, the wearable keyboard 100 may determine that the user has inputted the virtual keyboard, and may determine the signal input by the user as the input signal.

According to one disclosure, the flex sensor 111 may be installed so as to correspond to the first joint to the third joint of the user's finger. According to one disclosure, the flex sensor 111 may measure the bending information of the finger from a resistance value that is changed according to the bending degree of the user's finger in order to measure the bending degree of the user's finger. The flex sensor 111 may be made of a flexible element, and may include a bending resistance measuring element detachably attached to the terminal of the head socket. Accordingly, the flex sensor 111 is easily replaceable in the glove-type wearable keyboard 100 .

According to one disclosure, the gyro sensor 103 may be installed to correspond to the user's index finger. The gyro sensor 103 is generally used to accurately determine the input position of the index finger, which has the widest keyboard input range. More specifically, the wearable keyboard 100 may determine the output value by determining the left and right (x-axis) positions of the index finger from the sensing signal of the gyro sensor 103 .

It will be described in more detail below.

4 is a flowchart for explaining a series of processes of determining an output value from an input signal in a wearable keyboard, which is an input device of the present invention, and transmitting it to an external device.

According to one disclosure, the virtual QWERTY keyboard is a means for receiving a key set for each finger of the wearable keyboard 100 rather than an actual keyboard, and the user can input the virtual QWERTY keyboard through a finger input according to inertia. have.

According to one disclosure, in block 201 , the wearable keyboard 100 may determine whether the first sensing data obtained from the pressure-sensitive sensor corresponds to a threshold value or more. According to one disclosure, the first sensed data represents a pressure signal recognized by the wearable keyboard 100 through a pressure sensor. For example, when a user applies pressure to a flat bottom surface while wearing the wearable keyboard 100, when the pressure applied by the pressure sensor corresponds to a threshold value or more, the input value is converted to the first sensing data can decide According to one disclosure, when the value of the first sensing data is less than or equal to the threshold value, the wearable keyboard 100 may reduce energy for analyzing unnecessary input by determining it as an error value rather than data for inputting the keyboard. .

According to one disclosure, the wearable keyboard 100 may compare the pressure input from the pressure sensor with a predetermined threshold, and select and recognize the input level according to the comparison result. The threshold value by one start may be a value preset by the user. In addition, the threshold value according to the initiation may be a pressure value customized to the user based on the user's profile.

According to one disclosure, the wearable keyboard 100 may set a time point when a pressure greater than a threshold value is inputted as a specific time point or a specific time period, and selects the input level according to the pressure input at a recognition time. can be characterized as Here, the recognition time may be set to a time of 50 ms to 150 ms based on a point in time when a pressure equal to or greater than a predetermined level is input from the pressure-sensitive sensor.

According to one disclosure, in block 202, the wearable keyboard 100 may determine the y-axis position of the input signal from the second sensing data obtained from the flex sensor. According to one disclosure, the wearable keyboard 100 may determine a preliminary output value preset to the predetermined finger based on the predetermined finger that has acquired the first sensing data.

According to one disclosure, the preliminary output value indicates one keyboard key per line of a predetermined virtual QWERTY keyboard. For example, based on the English virtual QWERTY keyboard keyboard, W. S. X may be assigned to the left ring finger, and E, D, and C may be assigned to the left middle finger. However, in the case of the index finger, two keyboard keys may be assigned to each line of the virtual QWERTY keyboard. For example, Y, U, H, J, N, M may be assigned to the index finger of the right hand based on the English virtual QWERTY keyboard keyboard, and T, R, G, F, B, V may be assigned to the index finger of the left hand. can be

According to one disclosure, the wearable keyboard 100 may determine the output value of the signal input by the user by determining the y-axis position of the finger at which the input signal is detected from the second sensing data. In this case, the wearable keyboard 100 may determine a reference point for determining a y-axis position before inputting a character after starting pairing with the external device 600 . For example, the wearable keyboard 100 may receive a message requesting to start inputting text from the external device 600 , and may set a reference point according to receiving a message requesting to set a reference point on the y-axis. Also, according to another embodiment, the wearable keyboard 100 may set a reference point through an application for keyboard input. The method of setting the y-axis reference point is not limited.

According to one disclosure, in block 203 , the wearable keyboard 100 may determine whether the input signal is a signal obtained from the index finger. When the input signal is the index finger, since it has two preliminary output values at the same y-axis position, an additional process for accurate position determination is required.

According to one disclosure, in block 204 , when it is determined that the input signal is an input signal from the index finger, the wearable keyboard 100 may determine the x-axis position of the input signal from the third sensing data. According to one disclosure, the wearable keyboard 100 may preset a reference point for determining an x-axis position. According to one disclosure, the wearable keyboard 100 may set a reference point for determining the left and right positions of the input signal at a predetermined point in time after being connected to an external device. The wearable keyboard 100 may determine whether the signal is detected from the left side or the right side from the reference point using the signal sensed by the gyro sensor. For example, when the y-axis position of the input signal acquired from the right index finger is the uppermost part, the preliminary output values are Y and U, and when it is determined as the right value based on the reference point, the final output value is U.

According to one disclosure, in block 205 , the wearable keyboard 100 may determine an output value from location information of an input signal. The wearable keyboard 100 may determine the final output value by combining the position information of the input signal. For example, when a plurality of input signals are input, a value obtained by combining the plurality of input signals may be transmitted as an output value to an external device.

According to one disclosure, in block 206 , the wearable keyboard 100 may transmit an output value to the upper body device using a communication module. According to one disclosure, the communication module may include a module capable of wireless or wired communication. More specifically, the communication module may include a short-range wireless communication module, for example, the short-range wireless communication method may include various methods such as NFC method, Bluetooth, Wi-Fi, Zigbee, barcode recognition method, QR code recognition method, etc. have.

More preferably, the compound represented by Formula 2 may be a compound represented by Formula 3 below.

[Formula 3]

Here, m and p are as defined in Formula 2 above.

Preferably, the conductive filler may be selected from the group consisting of silica, alumina and mixtures thereof, but preferably alumina, but not limited to the above example. The conductive filler has a particle diameter of 30 to 50 μm, but is not limited to the above example. The conductive filler may exhibit electrical conductivity.

The graphite may be included in a small amount to continuously maintain the antistatic effect in the antistatic layer. Considering that graphite is an expensive conductive filler, it is included in a small amount in the antistatic layer in the present invention to maintain a continuous antistatic effect.

More specifically, the antistatic layer of the present invention may include polysiloxane represented by Formula 2; By including a conductive filler and graphite, it may exhibit an antistatic effect. The polysiloxane is divided into a hydrophilic portion and a hydrophobic portion. The hydrophilic moiety is capable of hydrogen bonding with a water molecule by an oxygen atom containing a lone pair of electrons. On the other hand, the alkyl group acts as a hydrophobic group. Accordingly, the hydrophilic part is positioned on the surface of the antistatic layer, and the hydrophobic part is positioned in the opposite direction, thereby exhibiting a semi-permanent antistatic effect.

For forming the antistatic layer, the antistatic composition is more specifically polysiloxane represented by the formula (2); It can be prepared by mixing a conductive filler, graphite, and an 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

(Parts by weight) The alumina has a particle diameter of 30 to 50 μm.

2. 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 the polyamide resin, and then thermal curing.

[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.

3. 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 to form a uniform coating layer.

According to one disclosure, the wearable keyboard 100 may include ten pressure-sensitive sensors 101 installed to correspond to the distal ends of each of the user's ten fingers. According to one disclosure, the ten pressure-sensitive sensors 101 may include unique identification information corresponding to each finger. Accordingly, when the pressure equal to or greater than the threshold value is sensed, the wearable keyboard 100 may determine the preliminary output value by determining the finger at which the 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, that is, pitch, roll, and yaw, may be obtained by using the measured values for the gyro and magnetic fields.

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 view 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 where 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 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 a point in time when the pressure of a predetermined size or more is started to be input from the pressure-sensitive sensor unit. And more preferably, it is 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 during a predetermined time from a time when the pressure of a predetermined level or more is started to be input from the pressure reduction sensor 101 . Preferably, the time when the pressure has a maximum value may be the recognition time.

Here, the wearable keyboard 100 may analyze a 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 of more accurately recognizing the size of the pressure intended by the user and determining 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 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 a threshold value most suitable 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 for users having each age, gender, and physical condition according to the statistical result of the experiment, and 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 according to the user's age, gender, and physical condition may be set in a setting program. 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 or a user in their 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 in order to select the input level using the pressure input from the pressure-sensitive sensor 101 .
