All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the term "connected" is to be interpreted broadly, e.g. as a fixed connection, a detachable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Please refer to fig. 1 to 9 for describing a gesture recognition mechanism, a glove and an electronic recognition device according to an embodiment of the present invention.
Referring to fig. 1 to 6, an embodiment of the invention provides a gesture recognition mechanism 20, where the gesture recognition mechanism 20 includes an optical fiber recognition unit 210 and a photoelectric conversion module 220, the optical fiber recognition unit 210 is provided with a temperature detection unit 2110, and the photoelectric conversion module 220 is connected to the optical fiber recognition unit 210 and is adapted to emit light with a preset frequency to the optical fiber recognition unit 210. The temperature detecting unit 2110 is disposed on an optical path of the optical fiber identification unit 210.
It should be noted that the optical fiber identification unit 210 may be disposed on the object to be identified, and the photoelectric conversion module 220 emits light with a preset frequency to the optical fiber identification unit 210, so that when the optical fiber identification unit 210 is bent along with the object to be identified, the real-time gesture change of the object to be identified can be predicted according to the difference of the loss values of the optical fibers at different bending angles. Meanwhile, the temperature detection unit 2110 is arranged on the light inlet and outlet path, so that an external temperature change value can be obtained in real time in the gesture recognition process.
In a further embodiment of the present invention, the temperature detecting unit 2110 is a gallium arsenide crystal, and obtains temperature information according to information about a change in transmittance of the gallium arsenide crystal. Specifically, the temperature detection unit 2110 detects the temperature according to the absorption and scattering characteristics of gallium arsenide to light, and it should be noted that the influence of temperature change on the semiconductor can be predicted, and for gallium arsenide crystals, as the temperature of the crystal increases, the transmission spectrum jumps to a spectrum with longer wavelength, at any given temperature, the fiber transmission jumps from 0% to 100% of the initial specific wavelength, and when the jump occurs, the relationship between the temperature and the specific wavelength can be predicted, thereby realizing the measurement of the temperature. In the light path, a part of the light is absorbed by the gaas crystal, a wavelength transition is generated, and the position of the absorption transition can be analyzed and correlated with a temperature value, thereby predicting a temperature value at which the finger structure 110 sets the periphery of the gaas crystal.
In the process of bending the finger structures 110, the optical fiber identification unit 210 is also bent, the bent optical fiber generates extra optical fiber loss compared with the optical fiber in a normal straight state, and the finger gesture is obtained by comparing the loss value of the optical fiber attached to each finger structure 110. The finger bending does not influence the measurement of the temperature value by the gallium arsenide crystal. Meanwhile, the gallium arsenide crystal has universality and constancy of response to temperature, so that probe calibration is not needed.
In an alternative embodiment of the present invention, referring to fig. 6, the optical fiber identification unit 210 includes an optical fiber core 2120, an optical fiber cladding 2130 sleeved outside the optical fiber core 2120, an anti-fouling coating 2140 sleeved outside the optical fiber cladding 2130, and an abrasion-resistant layer 2150 sleeved on the anti-fouling coating 2140. The fiber cladding 2130 is a layer of glass or other transparent material that covers the outside of the optical fiber core 2120 that carries the light waves, and has a lower refractive index than the optical fiber core 2120, and therefore can confine light to propagate within the optical fiber core 2120. The anti-fouling coating 2140 may be an acrylic coating that serves as a protective layer to prevent damage to the optical fiber core 2120 and the optical fiber cladding 2130 from external contaminants. The wear-resistant layer 2150 may be a kevlar sleeve layer, that is, the wear-resistant layer 2150 is formed by coating kevlar material, thereby improving wear resistance.
In some embodiments of the present invention, a glove is further proposed, and the glove can be used as the above-mentioned identification object, and the content glove provided in the embodiments of the present invention is described in detail through some embodiments and application scenarios thereof with reference to fig. 1 to 9.
Referring to fig. 1, according to the glove provided by the embodiment of the present invention, the glove includes a body 10 and a gesture recognition mechanism 20, a finger structure 110 is disposed on the body 10, and an optical fiber recognition unit 210 is disposed on at least one side of opposite sides of the finger structure 110. That is, the finger structures 110 of the glove correspond to the finger features of the user, and since the finger gaps exist between the adjacent fingers, the optical fiber identification units 210 are arranged corresponding to the positions of the finger gaps, so that the optical fiber identification units 210 do not occupy too much space of the glove. Compare in traditional gesture recognition mechanism 20, additional strip or cubic deformation resistance is the sensor on the finger, and the sensor structure occupies the too much space of gloves structure for the whole volume of gloves is great, and then the long just can produce fatigue effect of user's live time, and then influences the wearing and experience. In the embodiment of the invention, the optical fiber identification unit 210 is arranged on the side edge of the finger structure 110, the finger drives the optical fiber identification unit 210 on the side edge to bend in the bending process, the fatigue feeling caused by bending the finger is less affected by the arrangement of the optical fiber identification unit 210, the overall size of the glove is not increased, and the hand feeling when a user wears the glove and uses the glove is improved.
In an alternative embodiment of the present invention, the glove is adapted to the hand worn by the user, and the body 10 includes a back side and a center side corresponding to the hand of the user, an inner space for the user to wear and an outer space opposite to the inner space. The outer space corresponding to the inner space of the body 10 between the adjacent finger structures 110, the finger structures 110 are adapted to the shape of the hand of the user, that is, an outer gap corresponding to the gap between the fingers of the user exists between the adjacent finger structures 110, so that the user can complete various gestures of bending a single finger structure 110 or bending a plurality of finger structures 110 after wearing the finger structures. And the fiber identification unit 210 is disposed adjacent to the outer gap side of the adjacent finger structure 110. Therefore, the position of the optical fiber recognition unit 210 does not occupy too much space of the finger structure 110, so that the user can normally perform gesture recognition through the gesture recognition mechanism 20 after wearing the glove, and the body 10 does not need to have an increased overall size to influence the hand feeling of the user wearing the glove due to the additionally arranged gesture recognition mechanism 20.
For the optical fiber identification unit 210, the optical fiber identification unit 210 is disposed on at least one side of the opposite sides of the finger structure 110, that is, one optical fiber identification unit 210 may be disposed on both sides of each finger structure 110, or the optical fiber identification units 210 are disposed on both sides of each finger structure 110.
Traditional gesture recognition gloves, will attach strip or platelike deformation resistance and regard as the sensor discernment to catch the positional information that the finger buckled in the gloves, sensor one end is fixed in finger tip position department, the other end is located finger root position and is close to palm department, the user's finger drives the sensor and buckles in crooked in-process, because strip or platelike deformation resistance is equipped with fixed part in fingertip position, need apply bigger dynamics when causing finger tip position to buckle, user's long-time operation produces fatigue easily, and for accurately catching finger structure 110's gesture posture, the volume and the area of sensor all can be bigger and wrap whole finger structure 110, make the structure of gloves body 10 become bigger from this, whole volume also can correspond the grow, and then influence the user and dress, feel when using gloves. In the glove provided by the embodiment of the invention, the optical fiber identification unit 210 is used as the gesture identification mechanism 20, the size of the optical fiber identification unit 210 is smaller than that of a traditional strip-shaped or plate-shaped deformation resistor, and the optical fiber identification unit is arranged on the side edge of the finger structure 110 and corresponds to a gap, namely a finger slit, existing between adjacent finger structures 110, so that more placing space of the body 10 is not occupied, the influence on the whole size of the body 10 is small, the wearing requirements of light weight and small size of the glove are met, and compared with a traditional electrified sensor, the optical fiber identification unit 210 is higher in safety in the using process and does not need extra electricity utilization protection measures.
In some embodiments of the present invention, the temperature detecting unit 2110 is incorporated in the optical path of the fiber identification unit 210. That is, through the setting of the temperature detecting unit 2110, the optical fiber identification unit 210 can simultaneously obtain a real-time temperature value of the current environment where the finger structure 110 is located during the preset gesture process of the finger structure 110.
For example, in an alternative embodiment of the present invention, the temperature detecting unit 2110 may use the temperature value as an early warning value to perform a warning. The specific use scenario may be that, when the user wears the glove and rides a bicycle, the user controls the incoming call on/off state of the phone by presetting the bent left-hand thumb or the bent right-hand thumb in a state of connecting the headset, so that the user can bend the left-hand thumb or the right-hand thumb in a riding process, and the optical fiber recognition unit 210 obtains the corresponding gesture feature and sends the gesture feature to the electronic device 30, such as a mobile phone. The electronic device 30 controls the on-off of the telephone, and potential safety hazards caused by riding with one hand are avoided. Meanwhile, the temperature detecting unit 2110 senses the external temperature, and then a temperature prompt, such as a vibration prompt or a ring tone prompt, can be set on the electronic device 30 at the same time, so that the user can obtain the real-time temperature change of the external environment within a preset time period. For example, the method can be applied to mountain riding competitions, and can communicate with specific personnel through specific gestures along with the change of external temperature in the riding process. For example, the left thumb is bent to connect with the communication function and dial to the staff, so as to contact with the staff, and meanwhile, the staff can receive the real-time temperature change value at the position of the competition staff to correspondingly guide the competition staff. Specific scenarios may be used for rescue or emergency notification, etc. to improve the security of the competition.
In other optional embodiments, the temperature detecting unit 2110 may also be applied to a human-computer interaction scenario, and a user may wear AR or VR glasses and wear gloves simultaneously, and after entering a game space, the first time period corresponds to the first temperature value and also corresponds to the first game operation experience. Therefore, the change of the temperature value is combined into the human-computer interaction node, and the game experience of the user is improved. The first time period and the second time period are taken as an example for explanation, but the invention is not limited thereto.
In some other alternative embodiments, the temperature detecting unit 2110 may also be applied to a cold storage, and during the process of arranging goods in the cold storage by wearing gloves, for example, the user may need to control the on/off of the phone by bending the finger structure 110 into a designated shape, and at the same time, the location area of the storage where the gloves are located may be measured and recorded by the temperature detecting unit 2110. For example, when the thumb of the left hand and the thumb of the right hand are bent, the electronic device 30 is in an operating state and starts the software for recording the temperature value, so that the current temperature value of the compartment can be acquired and recorded, and therefore, the user can control the electronic device 30 and acquire the temperature value of the designated compartment even when wearing gloves in the cold compartment.
Referring to fig. 2 to 4, in some embodiments of the present invention, the temperature detecting unit 2110 is disposed on an incoming and outgoing optical path of the optical fiber identification unit 210 at the top end of the finger structure 110. That is, for finger structure 110, temperature detecting unit 2110 is located the top of finger structure 110, and along with the user buckles finger structure 110 many times, the temperature value of palm of the hand department can change, and the temperature variation of the top position department of finger structure 110 is less relatively, and more presses close to the ambient temperature value, and the temperature that consequently measures is more close to with the real-time temperature value in the external world to improve the accuracy of measuring to the ambient temperature value. However, in other alternative embodiments, the temperature detecting unit 2110 may also be disposed on a side of the finger structure 110 close to the palm, and monitor a temperature change at the palm position, which is not limited herein and may be adjusted according to an actual application scenario.
In some embodiments of the present invention, the fiber identification unit 210 is disposed on one of the opposite sides of the finger structure 110. That is, as for the finger structure 110, referring to fig. 2 to 4, the optical fiber identification unit 210 may be disposed on a single side of the finger structure 110, for example, may extend from a side near the palm of the hand to the tip of the finger structure 110. On the light incoming and outgoing path of the optical fiber identification unit 210, the light incoming side and the light outgoing side of the optical fiber identification unit 210 are disposed on the same side, the optical fiber identification unit 210 is located on one side of the finger structure 110, and a reflective mirror 2160 is disposed at the end of the optical fiber identification unit 210 far away from the light incoming side or the light outgoing side. Light enters from the light inlet side, flows to the reflector 2160 arranged at the tip end of the finger, and returns to the light outlet side after being reflected, and the reflector 2160 is convenient for light circulation to form a loop. For the temperature detecting unit 2110, the temperature detecting unit 2110 may be disposed between the reflective mirror 2160 and the light-entering side or the light-emitting side near the reflective mirror 2160, and the specific location is only by way of example and is not limited.
In still other embodiments of the present invention, referring to fig. 2, the optical fiber identification unit 210 is disposed on opposite sides of the finger structure 110, and for the light path, the light inlet side and the light outlet side of the optical fiber identification unit 210 are located on opposite sides of the finger structure 110. That is, the optical fiber identification unit 210 may extend to the other side of the finger structure 110 after bypassing the fingertip end through one side of the finger structure 110, and the light inlet side and the light outlet side are respectively located at the opposite sides of the finger structure 110. The light path is from one side of the finger structure 110 to the other side of the finger structure 110 after passing through the tip of the finger structure 110. The temperature detecting unit 2110 is arranged between the light inlet side and the light outlet side and is close to the finger tip, so that when light flows to the light outlet side through the light inlet side, the light can flow through the temperature detecting unit 2110, and temperature identification can be combined with gesture identification.
It should be noted that, in other alternative embodiments, the optical fiber identification units 210 may be separately disposed on two sides of the finger structure 110, for example, one optical fiber identification unit 210 is disposed on each side of the finger structure 110, the light entering and exiting sides of the optical fiber identification units 210 are disposed on the same side, and the reflectors 2160 are disposed at positions close to the fingertips of the finger structure 110, that is, two sets of the optical fiber identification units 210 are disposed. Therefore, when one of the fiber identification units 210 needs to be replaced, the other fiber identification unit 210 can be in a working state without influencing the normal use of the glove.
Referring to fig. 1 to 4 and fig. 8 to 9, in some embodiments of the present invention, the gesture recognition mechanism 20 further includes a photoelectric conversion module 220, wherein the light inlet side and the light outlet side of the optical fiber recognition unit 210 are both connected to the input end of the photoelectric conversion module 220, that is, the photoelectric conversion module 220 is configured to emit light with a predetermined frequency, receive the returned light, and convert the optical signal into an electrical signal for transmission. The main body 10 is further provided with a microprocessor 120 (MCU) for integrating interfaces such as a memory, a counter, a USB, an a/D converter, a PLC, etc. on a single chip to form a chip-scale computer. The photoelectric conversion module 220 is used for converting the optical signal of the optical fiber identification unit 210 into an electrical signal, and further transmitting the electrical signal to the microprocessor 120.
For example, when the body 10 is in the working state, the finger structure 110 is bent, the loss rate of the optical fiber identification unit 210 changes in the bending process of the transmitted optical signal of the finger structure 110, and the microprocessor 120 calculates the bending degree and the speed of the finger structure 110 by measuring the change amount and the trend of the loss rate. Therefore, the bending states of the finger structures 110 are measured simultaneously, and the gesture shape corresponding to the current finger structure 110 is obtained. For example, a plurality of gesture shapes may be preset on the electronic device 30 to form a gesture recognition library, when the user wears gloves, the plurality of finger structures 110 are bent to form a gesture feature, the data information of the gesture feature may be stored by the microprocessor 120 and compared with the gesture shapes of the gesture recognition library of the electronic device 30, so as to deduce the gesture feature of the current finger structure 110 of the user, and then the electronic device 30 makes a corresponding response according to the gesture feature.
Referring to fig. 5, the finger structure 110 is bent to form a gesture feature of "OK", which is associated with the on/off of the phone. That is, when the current finger gesture feature obtained by the microprocessor 120 is "OK", the corresponding response of the electronic device 30 is to control the phone to be turned on or off. For example, when a user is in a driving state, if the user needs to hang up the incoming call at the moment, the user can hang up the incoming call with one hand to cause potential safety hazards. Therefore, the telephone can be hung up only by making the gesture feature of 'OK' with one hand, so that the safety of the user in driving is improved. For example, the song in the car body needs to be switched, the song can be related to the switching function of the song by setting the extension or bending of the thumb, and the song can be paused by the extension or bending gesture of the index finger. The specific implementation scenarios are only illustrative and not limiting.
In still other embodiments of the present invention, a pressure sensor 1110 is provided on the finger structure 110 near the tip of the finger, and the output of the pressure sensor 1110 is connected to the input of the microprocessor 120. The pressure test is integrated into the body 10, so that the body 10 can realize the weighing effect of the object. For example, to buy goods in a shop, the bending of the finger structure 110 of the body 10 is associated with computing software specific to the electronic device 30. Such as bending of the finger structure 110, the weight of the cargo is measured by the finger tip pressure sensor 1110. And the finger structures 110 can be simultaneously associated with the calculation function of the electronic device 30, so that the weight and the corresponding price of the goods can be quickly obtained, and the weighing efficiency of the goods can be improved. Or in other alternative embodiments, for example, the cooking software is turned on by a specific gesture feature, the weight of the food material is measured by the pressure sensor 1110, and the recommended usage amount of salt, sugar and other seasonings is automatically calculated by the software according to the menu recommended ratio.

The communication module 140 is an Ultra Wide Band (UWB) communication module 140. The wireless carrier is used for communication, and the data is transmitted by adopting a nanosecond non-sinusoidal wave narrow pulse instead of a sinusoidal carrier, so that the occupied frequency spectrum range is wider. The body 10 and the electronic device 30 realize two functions of communication and positioning through the communication module 140. As used herein, an "electronic device 30" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal).

The nine-axis sensor is a combination of a three-axis accelerometer and a three-axis gyroscope memory three-axis magnetometer. The nine-axis sensor is used for acquiring the current three-axis acceleration, the three-axis acceleration and the three-axis magnetic field intensity of the finger structure 110 and transmitting data to the microprocessor 120, and the microprocessor 120 integrates the data information to obtain the pitch angle, the roll angle and the yaw angle of the current finger structure 110. In an alternative embodiment of the present invention, the nine-axis sensor is located at the back of the hand, whereby the finger structure 110 does not interfere with the nine-axis sensor during bending.

In another embodiment of the present invention, the optical fiber identification unit 210 is bonded and compounded on the side of the finger structure 110. Similarly, the optical fiber identification unit 210 extends from the end of the finger structure 110 close to the palm to the end close to the fingertip, so as to synchronize the bending state of the optical fiber with the bending state of the finger structure 110. In order to improve the precision of the optical fiber identification, it is necessary to ensure that the optical fiber is completely attached to the finger structure 110 in a bent state, i.e., the optical fiber identification unit 210 is completely adhered to the finger structure 110, and can be bent as the finger structure 110 is bent.
