Description

Hand-held gloves using knitted strain sensors

[0001] The present invention relates to a hand-held glove. More specifically, the present invention relates to a hand-held glove capable of detecting movement using a knitted strain sensor.

[0002] Sign language is a language used by deaf people to communicate using hand shapes and movements.

[0003] However, most people have difficulty communicating with deaf people because they do not understand sign language.

[0004] To solve these problems, Korean Patent Publication No. 2019-0115509, “Automatic Sign Language Recognition Method and System,” discloses a method for recognizing sign language by analyzing an image.

[0005] However, in order to analyze the video, there is a problem that a camera is needed to record the sign language movements, and the conversation partner cannot face the deaf person and have a natural conversation.

[0006] Additionally, there is the problem of not being able to make comfortable calls because you have to make video calls even when making phone calls, and you have to keep a certain distance so that all sign language movements are captured on camera.

[0007] Accordingly, a sign language interpretation / translation service system using a glove-type sign language recognition device with motion recognition sensors attached was developed.

[0008] However, sign language recognition devices that attach sensors to gloves have the problem of being uncomfortable to wear or of the sensing not being sensitive.

[0009] The purpose of the present invention is to provide a hand glove using a knitted strain sensor.

[0010] Another object of the present invention is to provide a hand glove using a knitted strain sensor and a 9-axis sensor.

[0011] Another object of the present invention is to provide a hand glove that has a comfortable fit.

[0012] Another object of the present invention is to provide a hand-held glove that fits closely to the body and can sensitively detect movement.

[0013] Another object of the present invention is to provide a hand glove with excellent reproducibility even after repeated use.

[0014] Another object of the present invention is to provide a hand glove that allows free movement.

[0016] The above and other objects of the present invention can all be achieved by a hand glove using a knitted strain sensor according to the present invention.

[0017] A water-resistant glove according to one embodiment of the present invention includes a glove module and a signal measuring module that is detachably coupled to the glove module and measures a signal according to the operation of the glove module.

[0018] The glove module may include five knitted strain sensors forming a portion of five finger insertion areas and a plurality of signal lines formed in a zigzag pattern on the glove module for electrical connection between each of the knitted strain sensors and the signal measurement module, and one end of which is connected to the knitted strain sensors.

[0019] In addition, the glove module further includes a plurality of connection terminals, and the signal measurement module includes a plurality of signal terminals corresponding to the connection terminals, and the signal measurement module can be detachably coupled to the glove module by a detachable connection between the connection terminals and the signal terminals.

[0020] According to one embodiment of the present invention, a hand glove may have one of a connecting terminal and a signal terminal that are connected to each other as a female part of a snap button and the other as a male part of the snap button.

[0021] Additionally, some of the multiple connectors may be female parts of the snap button and others may be male parts of the snap button.

[0023] The above signal measurement module can measure the electrical characteristics of the knitted strain sensor through two signal terminals connected to two connection terminals respectively connected to one side and the other side of the knitted strain sensor by two signal lines. At this time, one of the two signal terminals may be a ground terminal.

[0024] Additionally, the signal measurement module may further include a 9-axis sensor.

[0025] In addition, the signal measurement module may further include a communication unit that transmits the electrical characteristics measured using short-range communication and the measurement values ​​of the 9-axis sensor to the outside.

[0026] A sign language glove according to one embodiment of the present invention may further include an analysis module that receives the electrical characteristics and the measurement values ​​of the 9-axis sensor from a communication unit, analyzes the received electrical characteristics and the measurement values ​​of the 9-axis sensor to interpret sign language, and provides the interpreted sign language as text, voice, or image.

[0027] In a hand glove according to one embodiment of the present invention, the knitted strain sensor is made of at least one non-conductive yarn and at least one conductive yarn, and the non-conductive yarn and the conductive yarn can be woven to form the same loop of the knitted fabric, but the conductive yarn can be seen on only one side of the knitted fabric.

[0028] The above knitted fabric is woven with a plain fabric, one side may be the reverse side of the knitted fabric, and the knitted strain sensor may be positioned at a position corresponding to a finger joint so as to be elongated according to the bending of the finger.

[0050] Hereinafter, with reference to the attached drawings, a detailed description will be given of a hand glove and smart clothing using a knitted strain sensor according to the present invention.

[0051] In the following description, only the parts necessary for understanding the hand glove and smart clothing using the knitted strain sensor according to the embodiment of the present invention are described, and the description of other parts may be omitted so as not to distract from the gist of the present invention.

[0052] In addition, the terms or words used in the present specification and claims described below should not be interpreted as limited to their usual or dictionary meanings, but should be interpreted as meanings and concepts that conform to the technical idea of ​​the present invention so as to most appropriately express the present invention.

[0053] Throughout the specification, when a part is said to "include" a component, this does not exclude other components, but rather implies the inclusion of other components, unless otherwise specifically stated. Furthermore, terms such as "part," "unit," and "module" used in the specification mean a unit that processes at least one function or operation, which may be implemented using hardware, software, or a combination of hardware and software.

[0054] In various embodiments, components having the same configuration are described in one embodiment using the same symbols, and in other embodiments, components having different configurations from the one embodiment are described.

[0055] FIG. 1 illustrates a water-resistant glove (1) according to one embodiment of the present invention.

[0056] As illustrated in FIG. 1, a hand glove (1) according to one embodiment of the present invention includes a glove module (100) and a signal measurement module (200).

[0057] The glove module (100) is worn on the hand of a user using sign language and is the same as a general knitted glove.

[0058] The signal measurement module (200) is a module for recognizing hand movements of a user wearing a glove module, such as sign language.

[0059] As shown in Fig. 2, if automatic recognition of sign language is required, the user can use the glove module by combining the signal measurement module with the glove module, and if automatic recognition of sign language is not required, the user can separate the signal measurement module from the glove module, allowing the user to wear, store, and wash the glove module in the same way as wearing regular gloves.

[0060] A schematic diagram of the glove module (100) is shown in Fig. 3.

[0061] As illustrated in FIG. 3, the glove module (100) of the water glove (1) according to one embodiment of the present invention includes a knitted strain sensor (10), a signal line (20), and a connection terminal (30).

[0062] The knitted strain sensor (10) is a sensor that can detect the user's movement by using the resistance that changes according to the elasticity of the knitted fabric.

[0063] The knitted strain sensor (10) of the present invention has the greatest resistance when no external force is applied, and has the characteristic that when stretched by an external force, as shown in FIG. 4, the contact point between the conductive yarns (12) increases and the resistance decreases.

[0064] Therefore, by measuring the resistance of the knitted strain sensor, it is possible to detect the user's movement, for example, whether the finger is straight or bent.

[0065] In general, textile strain sensors using conductive fibers are lightweight, flexible, and stretchable, so they can be worn for long periods of time without causing discomfort to the user and continuously collect various human body data.

[0066] On the other hand, because the fundamental limitation of fiber materials is that their ability to return to their original state when the external force is removed is not complete, there is hysteresis between stretching and recovery, and it is difficult to reproducibly measure sensing performance during repeated stretching.

[0067] Accordingly, in order to overcome this drawback, the present invention configures a knitted strain sensor (10) so that a non-conductive yarn (11) and a conductive yarn (12) form the same loop of a knitted fabric, as shown in FIG. 5.

[0068] The knitted strain sensor (10) of the present invention does not use a blended yarn made by mixing conductive fibers and non-conductive fibers into a single yarn, but uses at least one non-conductive yarn (normal yarn) and at least one conductive yarn (conductive yarn), so that the respective advantages of the non-conductive yarn and the conductive yarn are not halved.

[0069] In addition, preferably, in the present invention, a knitted strain sensor is formed with a plain weave as illustrated in FIGS. 4 and 5. When a knitted strain sensor is formed with a plain weave (P) as illustrated in FIG. 6, a resistance change occurs even with a small movement and a large resistance change according to stretching can be achieved compared to when a knitted strain sensor is woven with a pearl weave (Pu) or rubber weave (R).

[0070] In addition, more preferably, the knitted strain sensor (10) of the present invention can have a resistance change even with a small movement and a large resistance change according to stretching by positioning the conductive yarn on the side where the contact points between the yarns increase more according to the elongation of the knitted fabric among both sides of the plain fabric (the back (inside) of the plain fabric (plain stitch) shown in FIG. 4) (see FIG. 7, P-PS (F): an embodiment in which the conductive yarn is woven so that it is located only on the surface (outside) of the plain fabric, P-PS (R): an embodiment in which the conductive yarn is woven so that it is located only on the back (inside) of the plain fabric).

[0071] As shown in FIG. 8, the knitted strain sensor (10) of the present invention has a small average deviation of the sensing voltage value according to the motion during a repeated motion experiment and a uniform output signal value, so it can be confirmed that, unlike conventional knitted strain sensors, it is a sensor with small hysteresis and high reproducibility and reliability.

[0072] Referring again to FIG. 3, the glove module (100) of the present invention is configured so that the knitted strain sensor (10) as described above is formed as a part of the five finger insertion areas, thereby enabling the five knitted strain sensors to detect the movement of each of the five fingers.

[0073] In particular, it is desirable to weave the knitted strain sensor (10) so that it is positioned only in the corresponding part of the finger joint that can be extended when the finger is bent, so that it can sense the sign language movement well while reducing noise.

[0074] To this end, as shown in Fig. 9, a glove module is woven with a non-conductive yarn (11), but when weaving the part corresponding to the finger joint, conductive yarn (12) is supplied through a superior yarn (2) that supplies non-conductive yarn and a different superior yarn (3) and the height of these superior yarns is adjusted, so that one of the non-conductive and conductive yarns is positioned behind the other yarn, and the woven fabric can be woven so that the conductive yarn is visible only on one side of the knitted fabric.

[0075] In this case, non-conductive yarns that cannot transmit electrical signals are used, such as a 50:50 blend of acrylic and wool or a rayon / nylon / polyester / wool blend. Furthermore, a 1-ply rayon / nylon / polyester / wool blend and a 1-ply spandex blend can be used together as non-conductive yarns to provide greater elasticity.

[0076] Additionally, a conductive material can be a silver-coated material that is made conductive by coating silver on a non-conductive material such as polyester.

[0077] Next, the signal line (20) is a conductive line for electrical connection between the knitted strain sensor (10) and the signal measurement module (200).

[0078] As shown in Fig. 3, two signal lines (20) are connected to one side and the other side of one knitted strain sensor (10) so that the signal measurement module (200) can measure the electrical characteristics (resistance, voltage) of the knitted strain sensor.

[0079] Therefore, when there are five knitted strain sensors (10) in the glove module (100), ten signal lines (20) are formed.

[0080] Each signal line (20) has one end connected to a knitted strain sensor (10) and the other end connected to a connection terminal (30) to be described later.

[0081] The signal line (20) can be formed of the same conductive yarn as the conductive yarn (12) that constitutes the knitted strain sensor (10), and it is preferable to form it in a zigzag pattern as shown in Fig. 3 so that the signal line is not broken even if the glove module is stretched by an external force.

[0082] Next, the connection terminal (30) is a terminal that electrically connects the knitted strain sensor (10) of the glove module (100) and the signal measurement module (200).

[0083] For electrical connection between the knitted strain sensor and the signal measurement module, the connection terminal can be connected 1:1 to the other end of the signal line (20). That is, when there are 10 signal lines (20), 10 connection terminals (30) can be provided in the glove module (100).

[0084] In addition, the signal measurement module (200) can be detachably connected to the glove module (100) through the connection terminal (30). In this case, the hand glove (1) does not need to have a separate configuration for connecting the glove module and the signal measurement module.

[0085] For this purpose, the connection terminal (30) has a structure that is detachably connected to the signal terminal (230) of the signal measurement module (200) described later.

[0086] A metal snap button (e.g., a spring snap button) can be used for the detachable connection of the connection terminal (30) and the signal terminal (230) and for the construction of a relatively inexpensive and simple hand glove (10).

[0087] That is, when one part of a pair of male and female parts constituting a snap button, for example, a female part, is configured as a connection terminal (30) of a glove module (100), the signal terminal (230) of a signal measurement module (200) coupled thereto can be configured as a male part.

[0088] At this time, in order to ensure that the paired connection terminals (30) and signal terminals (230) are accurately connected, it is preferable to configure some of the multiple connection terminals (30) as female parts and the rest as male parts.

[0089] That is, as illustrated in FIG. 3, the glove module (100) has five knitted strain sensors (10) to sense the movements of the thumb, index finger, middle finger, ring finger, and little finger. In addition, the signal measurement module (200) can be divided into signal terminals for the thumb, index finger, middle finger, ring finger, and little finger to accurately recognize how each finger moved.

[0090] In order to connect each signal terminal to the connection terminal (30) connected to the corresponding knitted strain sensor, for example, as shown in Fig. 11, only two signal terminals (230) that must be connected to the stop are configured as male parts, and the remaining signal terminals are configured as female parts, so that the connection terminals and signal terminals that are paired with each other can be accurately connected.

[0091] Next, the signal measurement module (200) is a module that acquires the electrical characteristics of the knitted strain sensor (10) to recognize the movement of a user wearing the glove module (100).

[0092] The signal measurement module (200) may include a signal terminal (230), a control unit (240), a power unit (250), and a communication unit (260) as illustrated in FIG. 10.

[0093] The signal measurement module (200) is configured as a separate module from the glove module (100) as shown in FIG. 1, and as shown in FIG. 11, the components of the signal measurement module are positioned within the case (210) and only the signal terminal (230) coupled with the glove module can be configured to be exposed to the outside.

[0094] The signal measurement module (200) is coupled to the glove module by connecting the signal terminal (230) exposed to the outside to the connection terminal (30) of the glove module (100), and can be separated from the glove module by separating the signal terminal from the connection terminal.

[0095] The components of the signal measurement module (200) located within the case (210) can be located on both sides of the printed circuit board (220) as illustrated in FIG. 12.

[0096] Specifically, a plurality of signal terminals (230) may be positioned on one side of the printed circuit board (220).

[0097] The arrangement of the multiple signal terminals (230) corresponds to the arrangement of the connection terminals (30) of the glove module (100).

[0098] In addition, two terminals among the plurality of signal terminals (230) can be used to measure the electrical characteristics of one knitted strain sensor (10), and it is preferable that one of the two terminals be a ground terminal so that the current passing through the knitted strain sensor does not leak to another location.

[0099] In addition, the plurality of signal terminals (230) may be determined as terminals for measuring the electrical characteristics of a knitted strain sensor among the plurality of knitted strain sensors, and in order to accurately connect with the connection terminal (30) connected to the determined knitted strain sensor, some of the plurality of signal terminals may be configured as male parts and the remaining signal terminals may be configured as female parts, as described above.

[0100] Additionally, components such as a control unit (240, MCU), a power unit (250), and a communication unit (260) may be placed on the other side of the printed circuit board.

[0101] The control unit (240) can supply power to the knitted strain sensor (10) through the signal terminal (230) and measure voltage or resistance to measure the electrical characteristics of the knitted strain sensor.

[0102] The power supply unit (250) can supply power for measuring the electrical characteristics of the knitted strain sensor, and power for operating components of the signal measurement module (200), such as the control unit and communication unit.

[0103] The communication unit (260) can transmit the electrical characteristics of the knitted strain sensor measured by the control unit to an external analysis module (not shown) using short-range communication such as Bluetooth.

[0104] The knitted strain sensor (10) used in the hand glove (1) according to one embodiment of the present invention has a large resistance when the fingers are in a relaxed state, and therefore the voltage between the two signal terminals connected to both ends of the knitted strain sensor is the largest.

[0105] And when the finger is folded, the knitted strain sensor (10) is stretched, and as shown in Fig. 4, the contact point between the conductive threads increases, reducing the resistance. Accordingly, the voltage between the two signal terminals connected to both ends of the knitted strain sensor also decreases.

[0106] Therefore, the electrical characteristics (voltage or resistance) of each knitted strain sensor measured by the control unit show different values ​​depending on the change in the user's motion, as shown in Fig. 13, and the user's hand movements, i.e., sign language, can be interpreted using the electrical characteristics of each measured knitted strain sensor.

[0107] At this time, the sign language interpretation using the electrical characteristics of each knitted strain sensor measured can be performed by the control unit (240) or by an external analysis module that receives the electrical characteristics of each knitted strain sensor through the communication unit (260).

[0108] However, recognizing only finger movements with a knitted strain sensor cannot distinguish between sign languages ​​in which the same finger is extended but the direction of the finger or the direction of the palm is different, as shown in Fig. 14.

[0109] Accordingly, the signal measurement module (200) according to one embodiment of the present invention may be configured to further include a sensor unit (270) capable of recognizing the palm direction (hand direction), finger direction (hand direction), hand position (hand level), hand movement (manual), etc. of a user wearing the glove module (100), as illustrated in FIG. 15.

[0110] The sensor unit (270) may include one or more of a gyro sensor, an acceleration sensor, and a geomagnetic sensor, and may be formed as a 9-axis sensor including all of these.

[0111] Accordingly, the control unit or external analysis module can interpret the sign language as illustrated in Fig. 16 using the electrical characteristics of each measured knitted strain sensor and the measurement values ​​by the sensor unit. At this time, if necessary, the starting motion of the sign language (e.g., a motion in which the fingers point upward and the palm faces forward) can be set, and the sign language can be interpreted based on the direction in which the palm is rotated in the starting motion.

[0112] Additionally, the control unit and analysis module can collect a large amount of electrical characteristics of knitted strain sensors from various users and learn them using a deep learning model, thereby enabling more accurate sign language interpretation.

[0113] Additionally, sign language interpreted by the control unit and external analysis module can be provided in various forms such as text, voice, and image, and through this, it can be understood that even a person who does not know sign language can easily converse with a person who uses sign language.

[0114] So far, the hand glove using the knitted strain sensor according to the embodiment of the present invention has been described with reference to specific examples.

[0115] However, as illustrated in FIG. 17, if the glove module (100) is configured as clothing having a knitted strain sensor, signal line, and connection terminal located at the joint area, it can be understood that the signal measurement module (200) is combined to function as smart clothing capable of measuring the user's motion, such as the degree of bending of the joint area.

[0116] Also, although Korean sign language gestures are explained as examples in FIGS. 13, 14, and 16, it will be understood that sign language gestures of other languages ​​can also be recognized in the same way.

[0117] It should be understood that the present invention is not limited to these specific embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention as claimed in the claims.
