Description

Technical Field

[0001] The present invention relates to the technical field of emotion recognition bracelets, and in particular to a method and a device for identifying emotions of infants. Background Art

[0002] In modern society, many parents have to send their children to nurseries or kindergartens or hire nannies to take care of them due to the pressure of life and work. When they are not around, they really want to know their children's living conditions in nurseries or kindergartens, whether they are happy, sad, angry, or happy, etc. However, due to the limitations of realistic conditions, parents of infants and young children cannot always understand what changes have occurred in their children's emotions. Moreover, compared with adults, infants and young children cannot express their emotions completely and clearly due to their young age, so a method that can identify children's emotions is particularly important. The James-Lange emotion theory believes that there is a direct relationship between human emotional changes and physiological changes in the body. For example, anger causes more heart rate increases than happiness; when sad or happy, the skin temperature will rise, but the skin temperature of a person in a sad mood is lower than that of a happy person; disgust and fear are more likely to cause an increase in skin conductance than happy emotions. Through experiments, researchers have found that a person's heart, nerve muscles, breathing depth and frequency, and skin electricity also change with changes in emotions. For example, when a person is angry, his breathing is short and the frequency increases, while when he is sad, his breathing is relatively slow and the frequency decreases. Since the emotional process is always accompanied by such changes in physiological activities, we can use such physiological changes to judge the emotional response state of infants and young children.

[0003] When using existing bracelets with emotion recognition functions, if there is sweat or other liquids remaining on the skin surface after the user exercises or washes his hands, the contact between the skin conductance sensor and the skin is prone to abnormal fluctuations, causing abnormal skin conductance information, resulting in subsequent emotion analysis results that are prone to errors. When manually cleaning the bracelet and wrist, the bracelet needs to be taken off and handled, which is troublesome and difficult to clean in time. Summary of the invention

[0015] A method for identifying children's emotions, the specific steps of the method for identifying children's emotions are:

[0016] Step 1: Determine the types of infant emotions and construct a standard physiological signal library for infants under corresponding emotions. Divide infant emotions into crying, laughing, happiness, anger, anxiety, fear and excitement. Establish a standard physiological signal library for infants under corresponding emotions. The standard physiological signal library for infants includes heart rate signals, skin conductivity signals, skin temperature, sound data signals, and limb activity signal data. Establish an emotion classification model.

[0017] Step 2: Manually input the user's gender, weight, and age information, and the terminal assigns a specific emotion classification model based on the personal information;

[0018] Step 3: Collect information on the physiological signals and behavioral characteristics of the human body through the sensors on the emotion recognition device, and input the characteristic information into the classification model to determine the final emotion category recognition result. Specifically, collect the sound through the microphone, and then identify the user's crying and laughing emotions through voice recognition. When the user is identified as crying or laughing, control the lamp beads to emit blue light to provide a calm and comforting atmosphere. Use the heart rate sensor to analyze the user's heart rate variability (HRV) and UID heart rate frequency. When the user is in a happy or positive emotion, the heart rate variability is 10%-15% higher than the average level. When the user is angry, the heart rate will increase by 5-7 times / minute, so as to assist in identifying the user's happy and angry emotions based on the heart rate sensor. When it is determined that the user is in a happy or positive emotion, control the lamp beads to emit yellow light to increase the happy and energetic atmosphere. When it is determined that the user is in an angry emotion, control the lamp beads to emit yellow light to increase the happy and energetic atmosphere. Green light is emitted to relieve anger and provide a peaceful atmosphere. The skin electrical activity is detected through the skin conductance sensor. When the user is anxious or nervous, the sweat gland activity increases, thereby increasing the skin conductivity, making the response speed of the skin electrical activity 3-5 times faster, thereby identifying anxious emotions. When it is determined that the user is in an anxious mood, the lamp beads are controlled to emit blue light. The temperature sensor is used to detect changes in skin temperature. When fear occurs, it may cause peripheral blood vessels to contract, thereby affecting skin temperature. Therefore, when the skin temperature is detected to drop by an average of 1-3°C, it is determined that the user is in a fearful mood, and the lamp beads are controlled to emit blue light. The acceleration sensor is used to detect the user's exercise intensity. When the amount of exercise activity is detected to increase by 20%-40%, it is determined that the user is in an excited mood, and then the lamp beads are controlled to emit red light to activate excitement. The emotion recognition results are uploaded to the server, and the recognition results are sent to the mobile device through the server.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the setting of the connecting valve, when the skin conductance information collected in the sensor assembly is detected to be abnormal, the control driving module is started, and the driving module inflates the airbag through the piston chamber to push the wristband body upward, so that the bottom surface of the wristband body is separated from the wrist skin. Then, when the air pressure in the airbag continues to increase, the gas in the airbag is ejected through the air outlet, so as to blow between the sensor assembly and the wrist skin, thereby accelerating the evaporation of water stains and sweat stains, so that the sensor assembly resumes collecting information on the skin surface;

[0021] 2. Through the setting of the connecting valve, when the airbag is inflated, the air pressure in the airbag increases, so that the gas overcomes the elastic force of the reset spring 2 and pushes the sealing plate downward, the holder releases its support for the fixing frame 3, and the closing seat overcomes the elastic force of the reset spring 1 and moves downward, and the gas is discharged from the air outlet duct. The air pressure in the airbag drops, so that the closing seat moves upward under the action of the reset spring 1, and the fixing frame 3 moves upward to squeeze the holder and move over the holder to the top of the holder, and then the holder pops up again to support the fixing frame 3 to prevent the sliding bar from moving downward, and the closing seat re-closes the connecting chamber 1, so that the gas in the airbag accumulates again, so that after the airbag lifts up the bracelet body, it blows between the bottom surface of the bracelet body and the skin, realizing intermittent cycle blowing on the skin, thereby improving the efficiency of cleaning water stains on the skin surface.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 7 In an embodiment of the present invention, an emotion recognition device includes a wristband body 100, wristbands 140 are fixedly installed at both ends of the wristband body 100, a sensor assembly 150 is embedded and installed on the bottom surface of the wristband body 100, a placement cavity 111 is opened at one end of the bottom surface of the wristband body 100, and an installation airway 113 is opened inside the wristband body 100 at one side of the placement cavity 111, and the top of the installation airway 113 is connected to the inner top surface of the placement cavity 111. There is a connecting air duct 112, an air outlet duct 114 is opened at the bottom end of the installation air duct 113, an air bag 120 is fixedly installed on the inner top surface of the placement cavity 111, one end of the bracelet body 100 is located on the other side of the placement cavity 111 and a driving module 130 is provided. The driving module 130 is used to inflate the air bag 120, and a connecting valve component 200 is installed on the inner wall of the installation air duct 113. The connecting valve component 200 is used to intermittently close and connect the installation air duct 113.

[0032] Specifically, when the skin conductance information collected in the sensor assembly 150 is detected to be abnormal, the control driving module 130 is started, and the driving module 130 inflates the airbag 120 through the piston chamber 116, and the connecting valve member 200 is in a closed state, so that the airbag 120 expands, the air pressure in the airbag 120 rises, and after the airbag 120 expands downward, the wristband body 100 is pushed upward, so that the bottom surface of the wristband body 100 is separated from the wrist skin, and then when the air pressure in the airbag 120 continues to increase, the sealing of the installation airway 113 is released through the connecting valve member 200. The gas in the airbag 120 is ejected through the connecting airway 112, the installation airway 113 and the air outlet airway 114, so as to blow between the sensor assembly 150 and the wrist skin, thereby accelerating the evaporation of water stains and sweat stains. When the airbag 120 is deflated, it gradually shrinks into the placement cavity 111, and the connecting valve 200 re-closes the installation airway 113, and the airbag 120 is re-inflated. This cycle is repeated until the sensor assembly 150 and the wrist skin are blown multiple times, and then the sensor assembly 150 re-detects the skin conductance and collects signals.

[0033] Embodiment 1

[0034] like Figure 2-5 As shown, in this embodiment, the sensor assembly 150 is provided with a skin conductance sensor, an acceleration sensor, a temperature sensor, a heart rate sensor and a microphone, and a lamp bead is installed in the wristband body 100.

[0035] Specifically, the sound is collected through the microphone, and the crying and laughing emotions of the user are identified through voice recognition. When the user is identified as crying or laughing, the lamp beads are controlled to emit blue light to provide a calm and comforting atmosphere. The user's heart rate variability (HRV) is analyzed and the UID heart rate frequency is measured through the heart rate sensor. When the user is in a happy or positive emotion, the heart rate variability is 10%-15% higher than the average level. When the user is in an angry emotion, the heart rate will increase by 5-7 times / minute. The heart rate sensor can be used to assist in identifying the user's happy and angry emotions. When it is determined that the user is in a happy or positive emotion, the lamp beads are controlled to emit yellow light to increase the happy and energetic atmosphere. When it is determined that the user is in an angry emotion, the lamp beads are controlled to emit green light to relieve anger and provide and Peaceful atmosphere, the skin electrical activity is detected through the skin conductance sensor. When the user is in an anxious or nervous mood, it will cause increased sweat gland activity, thereby increasing skin conductivity, making the response speed of skin electrical activity 3-5 times higher, thereby identifying anxious emotions. When it is determined that the user is in an anxious mood, the lamp beads are controlled to emit blue light. The temperature sensor is used to detect changes in skin temperature. When fear occurs, it may cause peripheral blood vessels to contract, thereby affecting skin temperature. Therefore, when the skin temperature is detected to drop by an average of 1-3°C, it is determined that the user is in a fearful mood, and the lamp beads are controlled to emit blue light. The acceleration sensor is used to detect the user's exercise intensity. When the amount of exercise activity is detected to increase by 20%-40%, it is determined that the user is in an excited mood, and then the lamp beads are controlled to emit red light to activate excitement.

[0037] In this embodiment, the motor 131 drives the disc 132 to rotate, and the disc 132 drives the piston plate 135 to move forward and backward through the round rod 133 and the connecting rod 134, so that the piston plate 135 moves forward and backward in the piston cavity 116. When the piston plate 135 moves forward in the direction close to the one-way air valve 110, the one-way air valve 118 is in a closed state, and the gas in the piston cavity 116 is squeezed through the one-way air valve 110 and the connecting air channel 117 to inflate the airbag 120. When the piston cavity 116 moves backward, the one-way air valve 110 is closed and the one-way air valve 118 is opened, so that the outside air is sucked into the piston cavity 116 through the one-way air valve 118, thereby realizing the inflation of the airbag 120.

[0040] In specific implementation, when the airbag 120 is inflated, the air pressure in the airbag 120 increases, so that the gas overcomes the elastic force of the return spring 244 and pushes the sealing plate 243 downward, and the sealing plate 243 drives the inclined block 241 to move downward, and the inclined block 241 drives the holder 230 to move laterally toward the side wall away from the slide bar 220 by squeezing the inner side wall of the card slot 231, and the reset spring piece 242 is compressed. The air pressure in the airbag 120 gradually increases, so that the holder 230 gradually moves laterally to one side until one side of the holder 230 is completely retracted into the connecting chamber 3 214, and the holder 230 releases the support for the fixing frame 3 223, so that the gas in the airbag 120 pushes the closing seat 221 to overcome the elastic force of the return spring 1 222 and move downward, so that the closing seat 221 releases the closure of the bottom end of the connecting chamber 1 211, so that the connecting chamber 1 211 is in a connected state, and the gas is discharged from the air outlet 1 14 is discharged, and then the sealing plate 243 moves upward under the action of the reset spring 244, and the holder 230 moves horizontally to the other side under the action of the reset spring 242, and the air pressure in the airbag 120 drops, so that the closing seat 221 moves upward under the action of the reset spring 1 222, and the fixing frame 3 223 squeezes the holder 230 when moving upward and moves over the holder 230 to the top of the holder 230, and then the holder 230 pops up again to support the fixing frame 3 223 to prevent the sliding bar 220 from moving downward, and the closing seat 221 re-closes the connecting cavity 1 211, so that the gas in the airbag 120 is re-accumulated, so that after the airbag 120 lifts up the bracelet body 100, it blows between the bottom surface of the bracelet body 100 and the skin, which is convenient for cleaning the water stains between the skin and the bracelet body 100, thereby improving the accuracy of emotion recognition of the bracelet body 100.

[0042] Step 1: Determine the types of infant emotions and construct a standard physiological signal library for infants under corresponding emotions. Divide infant emotions into crying, laughing, happiness, anger, anxiety, fear and excitement. Establish a standard physiological signal library for infants under corresponding emotions. The standard physiological signal library for infants includes heart rate signals, skin conductivity signals, skin temperature, sound data signals, and limb activity signal data. Establish an emotion classification model.

[0043] Step 2: Manually input the user's gender, weight, and age information, and the terminal assigns a specific emotion classification model based on the personal information;

Use the heart rate sensor to analyze the user's heart rate variability (HRV) and UID heart rate frequency. When the user is in a happy or positive emotion, the heart rate variability is 10%-15% higher than the average level. When the user is angry, the heart rate will increase by 5-7 times / minute, so as to assist in identifying the user's happy and angry emotions based on the heart rate sensor. When it is determined that the user is in a happy or positive emotion, control the lamp beads to emit yellow light to increase the happy and energetic atmosphere. When it is determined that the user is in an angry emotion, control the lamp beads to emit yellow light to increase the happy and energetic atmosphere. Green light is emitted to relieve anger and provide a peaceful atmosphere. The skin electrical activity is detected through the skin conductance sensor. When the user is anxious or nervous, the sweat gland activity increases, thereby increasing the skin conductivity, making the response speed of the skin electrical activity 3-5 times faster, thereby identifying anxious emotions. When it is determined that the user is in an anxious mood, the lamp beads are controlled to emit blue light. The temperature sensor is used to detect changes in skin temperature. When fear occurs, it may cause peripheral blood vessels to contract, thereby affecting skin temperature. Therefore, when the skin temperature is detected to drop by an average of 1-3°C, it is determined that the user is in a fearful mood, and the lamp beads are controlled to emit blue light. The acceleration sensor is used to detect the user's exercise intensity. When the amount of exercise activity is detected to increase by 20%-40%, it is determined that the user is in an excited mood, and then the lamp beads are controlled to emit red light to activate excitement.
