[0017] The above contents in combination with the implementation of the present invention are merely examples and explanations of the concept of the present invention. The technical personnel in the relevant technical field may make various modifications or supplements to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the claims, they shall all fall within the protection scope of the present invention.

[0018] Example 1: Please refer to Figure 1 As shown, a feedback device based on emotion monitoring includes a wearable device, an emotion perception module, a feedback module and a wireless communication module; The wearable device is used to be worn on special children and has multiple built-in physiological sensors for monitoring physiological signals of special children; The physiological sensors include but are not limited to heart rate sensors, galvanic skin response sensors, body temperature sensors, etc., which are used to monitor physiological indicators such as heart rate, galvanic skin response, and body temperature of children; the physiological sensors are integrated into a wearable device through flexible materials, and the device can be worn on the wrist, ankle or chest of the child to ensure comfort and accuracy of data collection.

[0019] Based on the above embodiment, the physiological signals of the special child include the time interval between two adjacent heartbeats and the skin conductivity and skin temperature at each monitoring time point.

[0020] The emotion perception module is used to determine the emotional state of special children through algorithms; Based on the above embodiment, the emotional state of a special child is judged, and the specific judgment process is as follows: Get the time interval between two adjacent heartbeats of a special child , i is the number of each two adjacent heartbeats, i=1,2,...N, N is the total number of numbers of two adjacent heartbeats; Calculating heart rate variability in special children , is the mean time interval between two adjacent heartbeats; Obtain the skin conductivity of special children at each monitoring time point , j is the number of each monitoring time point, j=1,2,...J; the skin conductivity changes of special children are calculated from this , J is the total number of monitoring time points, is the skin conductivity at the j-1th monitoring time point, Respectively represent the time of the j-th and j-1-th monitoring time points; Get the skin temperature of special children at each monitoring time point , from which the skin temperature changes of special children are calculated , is the skin temperature at the j-1th monitoring time point; The heart rate variability, skin conductivity change and skin temperature change of the special children are respectively compared with the heart rate variability interval values ​​corresponding to each set heart rate variability level, the skin conductivity change interval values ​​corresponding to each skin conductivity level and the skin temperature change interval values ​​corresponding to each skin temperature level, thereby obtaining the heart rate variability level, skin conductivity level and skin temperature level of the special children; Among them, each heart rate variability level, each skin conductivity level and each skin temperature level are specifically divided into low level, medium level and high level; If the heart rate variability level, skin conductivity level and skin temperature level of the special child are all identified as high levels, the special child is judged to be in a high arousal negative emotion; if the heart rate variability level, skin conductivity level and skin temperature level of the special child are all identified as low levels, the special child is judged to be in a low arousal negative emotion; otherwise, the special child is judged to be in a positive emotion.

[0021] The positive emotions are further divided into high arousal positive emotions and low arousal positive emotions; The four emotional states of high arousal positive emotions, high arousal negative emotions, low arousal positive emotions, and low arousal negative emotions can be distinguished by two dimensions: arousal level and emotional valence. Arousal level refers to the intensity of emotional activation, and valence refers to the positive or negative nature of the emotion. Specifically: High arousal positive emotions: refers to a state in which the level of emotional activation is high and the emotional experience is positive, usually manifested as extremely excited, happy and energetic emotions, such as ecstasy, excitement, excitement, etc. High arousal negative emotions: refers to a state where the level of emotional activation is high but the emotional experience is negative, usually manifested as strong anxiety, anger, fear or agitation, such as anger, panic, tension, etc. Low arousal positive emotions: refers to a state in which the level of emotional activation is low but the emotional experience is positive, usually manifested as calm, satisfied, relaxed and comfortable emotions, such as tranquility, serenity, warm happiness, etc. Low arousal negative emotions: refers to a state in which the level of emotional activation is low and the emotional experience is negative, usually manifested as tiredness, frustration, powerlessness or indifference, such as depression, sadness, burnout, etc.

[0022] The feedback module performs emotional intervention on the special child when it detects that the special child has emotional fluctuations; Based on the above embodiment, the detection logic for detecting the presence of emotional fluctuations in special children is: Comprehensive calculation of the intensity of emotional fluctuations in special children , are the set weights respectively; A comprehensive threshold S1 is set. When the emotional fluctuation intensity S of the special child is greater than S1, it is determined that the special child has emotional fluctuations.

[0023] Based on the above embodiment, the feedback module specifically includes a vibration control unit, a music playing unit and a light control unit.

[0024] Based on the above embodiment, the operation process of the vibration control unit is as follows: The vibration control unit is used to control the vibration intensity, vibration frequency and vibration duration of the wearable device; The vibration intensity of the wearable device The calculation formula is , is the maximum value of the intensity of emotional fluctuations, which can be determined through historical data; The maximum vibration intensity of the wearable device, which is limited by the device's hardware; The vibration frequency of the wearable device The calculation formula is , are the maximum and minimum values ​​of the vibration frequency of the wearable device, is the frequency of emotional fluctuations of special children at the jth monitoring time point; The vibration duration of the wearable device The calculation formula is , c is the number of each emotional fluctuation of the special child, c=1,2,...r; are the maximum and minimum values ​​of the vibration duration of the wearable device, The duration of the cth mood swing of special children.

[0025] The calculation formula for vibration intensity is based on the mapping relationship of the intensity of emotional fluctuations. The intensity of emotional fluctuations is obtained by combining multiple physiological signals (such as heart rate changes, skin conductance response, and skin temperature changes), which reflects the individual's level of emotional arousal. Studies have shown that the intensity of emotional fluctuations is closely related to changes in physiological signals. For example, under stress, both heart rate and skin conductivity will increase significantly, and these changes can be represented by quantitative indicators (such as the amplitude of heart rate changes and the amplitude of skin conductance response). Therefore, it is reasonable to map the changes in these physiological signals to vibration intensity. Adjusting the vibration intensity can allow children to perceive feedback more obviously, thereby helping them realize the occurrence of emotional fluctuations; The frequency of emotional fluctuations can be measured by the rate of change of physiological signals. For example, rapid fluctuations in heart rate or frequent changes in skin conductivity may represent a higher frequency of emotional fluctuations. Studies have shown that frequent emotional fluctuations are often associated with emotional states such as anxiety and stress, and individuals in these states need more frequent feedback to help them regulate their emotions. Adjusting the vibration frequency can enable the device to provide more intensive feedback when emotional fluctuations are frequent, thereby guiding individuals to self-regulate; The duration of emotional fluctuations can be estimated by the duration of abnormal physiological signals. For example, a sustained increase in heart rate or a prolonged abnormality in skin conductivity may indicate that emotional fluctuations persist. Studies have shown that prolonged emotional fluctuations (such as persistent anxiety or stress) often require longer intervention and feedback. Therefore, increasing the duration of vibrations can help children continue to feel feedback throughout the entire process of emotional fluctuations, thereby more effectively guiding them to regulate emotions; The calculation formulas for vibration intensity, vibration frequency, and vibration duration are based on the intensity, frequency, and duration of emotional fluctuations. It is reasonable to map changes in physiological signals to the parameters of vibration feedback. By combining experimental data and user feedback, the design of vibration feedback can be further optimized to achieve a more accurate emotional intervention effect.

[0026] Based on the above embodiment, the operation process of the music playing unit is as follows: The music playing unit is used to control the music rhythm and volume of the wearable device; The music rhythm of the wearable device The calculation formula is , They are the maximum and minimum values ​​of the music rhythm corresponding to the wearable device; The music volume of the wearable device The calculation formula is , They are respectively the maximum and minimum values ​​of the music volume of the wearable device.

[0027] The calculation formulas for music volume and music rhythm are designed based on the physiological response to emotional fluctuations and the mechanism of music's effect on emotional regulation. They have a reasonable theoretical basis and certain practical support. Music rhythm (usually expressed in beats per minute BPM) and volume (usually expressed in decibels dB) can directly affect a person's psychological and physiological state. For example, faster music rhythms generally induce higher levels of arousal, while slower music helps to relax and reduce stress. Similarly, higher volumes increase the level of emotional activation, while lower volumes help to create a calm atmosphere; Formula for music rhythm: The design of this formula is based on the negative correlation between the intensity of emotional fluctuations and the rhythm of music. Real-life studies have shown that higher emotional activation (such as anxiety or anger) is usually accompanied by rapid physiological reactions (such as increased heart rate and increased skin conductivity). At this time, playing slower music can help individuals relax and calm down. Therefore, when the intensity of emotional fluctuations is high, the formula will choose a slower music rhythm to help individuals relieve anxiety or stress. When emotional fluctuations are low, the formula will choose a faster music rhythm to increase the individual's arousal level and prevent the mood from being too low or tired. This rhythm adjustment based on the intensity of emotional fluctuations is widely used in music therapy and psychological intervention. For example, studies have shown that slow-tempo music of 60-80 BPM can help reduce anxiety levels, while music around 120 BPM can help increase concentration and vitality; Formula for music volume: The design of this formula is based on the positive correlation between the intensity of emotional fluctuations and the volume. Real-life studies have shown that changes in volume can significantly affect the level of emotional arousal. Higher volume levels generally enhance emotional experiences, increase attention and excitement, while lower volume levels help to relax and reduce stress. For example, in cases of anxiety or emotional excitement, lowering the volume can help individuals reduce external stimuli and enter a calm state. Conversely, when emotional fluctuations are weak, appropriately increasing the volume can enhance the level of arousal and help individuals better cope with low emotional states. Therefore, the formula ensures that the volume matches the individual's emotional state by dynamically adjusting the volume according to the intensity of emotional fluctuations.

[0028] Based on the above embodiment, the operation process of the light control unit is as follows: The light control unit is used to control the light brightness and light flashing frequency of the wearable device; The intensity S of emotional fluctuations of special children is quantified as the emotional index E, whose value range is [0,1], where E=0 means that the emotion is stable, and E=1 means that the emotional fluctuation reaches the maximum value; The emotional fluctuation intensity S of special children is normalized and mapped to the range of [0,1] to obtain the emotional index E; Mapping the emotional index E of special children to the light brightness of wearable devices , They are the highest brightness and lowest brightness corresponding to the wearable device respectively; Mapping the emotional index E of special children to the light flashing frequency of wearable devices , They are respectively the highest and lowest frequencies of the flashing lights of the wearable device.

[0029] Lower light levels are often associated with a relaxed, comfortable emotional state, while higher brightness may increase excitement or alertness. For example, studies have shown that soft light (low brightness) helps reduce anxiety and stress, while bright light (high brightness) may cause excitement or anxiety. Based on these studies, the brightness adjustment formula linearly relates the mood index to brightness changes. When mood fluctuations are small, the brightness is close to L_min (soft light), while when mood fluctuations are large, the brightness is close to L_max (stronger light), thereby influencing the emotional state through visual stimulation; Lower flicker frequencies (or no flicker) are usually associated with a relaxed state, while higher flicker frequencies may induce tension or excitement. Human sensitivity to flicker frequencies has a clear physiological basis in the visual nervous system: too fast flickering can cause discomfort and even induce epileptic seizures in some individuals (photosensitive epilepsy). It is reasonable for the formula to dynamically adjust the flicker frequency through the emotional index, which allows the use of lower frequencies when the emotional fluctuations are small, thereby reducing visual stimulation, and gradually increases the frequency when the emotional fluctuations are large to provide more obvious visual feedback; The wireless communication module is used to connect with the mobile terminal application through wireless transmission, and send a notification to the corresponding person in charge when the special child has emotional fluctuations, reminding him to intervene in time.

[0030] Example 2: Please refer to Figure 2 As shown, a feedback method based on emotion monitoring comprises the following steps: Step 1: Based on the built-in multiple physiological sensors of the wearable device, the physiological signals of the special children are monitored, and then the emotional state of the special children is determined through the algorithm; Step 2: When it is detected that the special child has emotional fluctuations, emotional intervention is carried out on the special child; Step 3: Connect with the mobile terminal application via wireless transmission, and send a notification to the corresponding person in charge when the special child has emotional fluctuations, reminding him to intervene in time.
