[0051] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] Example 1:

[0053] The embodiment of the present invention provides a method for assessing stress by physical and mental feedback, such as Figure 1 Shown, including:

[0054] S101, collecting user's psychological stress assessment data;

[0055] S102, determining a user's psychological stress assessment result based on the psychological stress assessment data;

[0056] S103, collecting user's facial expression data;

[0057] S104, determining a user's expression stress assessment result based on the expression data;

[0058] S105, collecting user's body pressure data;

[0059] S106, determining a user's body stress assessment result based on the body stress data;

[0060] S107 , determining the user's overall stress assessment result based on the user's psychological stress assessment data, facial expression stress assessment result, and physical stress assessment result.

[0061] Since single-dimensional stress assessment has great limitations, we conduct assessments from three dimensions: psychological, physical, and facial expressions, which effectively improves the accuracy of stress assessment.

[0062] The following describes the collection of multi-dimensional pressure:

[0063] Psychological stress is assessed by collecting user psychological stress assessment data, namely professional psychological scale assessments. This psychological stress assessment data can be used to deeply explore the user's subjective psychological perception of stress.

[0064] For example, the stress perception scale has a total of 14 questions, including 6 positive questions and 8 negative questions. The scoring method is: "never" is recorded as 1 point, "occasionally" is recorded as 2 points, "sometimes" is recorded as 3 points, "often" is recorded as 4 points, and "always" is recorded as 5 points. The final total score range is between 14 and 70 points.

[0065] Determine the user's psychological stress assessment results based on the assessment results, specifically according to the following table:

[0066]

[0067] The assessment of facial expression stress specifically involves collecting facial expression data of the user; and determining an assessment result of the facial expression stress of the user based on the facial expression data.

[0068] Specifically, the user's facial expression images are collected through a camera, and then the facial expression type is identified based on the facial expression data, which includes: calm, happy, sad, angry, frustrated, surprised and afraid; the number of facial expression image frames within a preset time length and the number of times the target facial expression frame appears within the preset time length are calculated, and the target facial expression frame is one or more of the facial expression types of sadness, anger, frustration, surprise and fear; based on the number of facial expression image frames and the number of times the target facial expression frame appears within the preset time length, the user's facial expression stress assessment result is determined.

[0069] In a specific implementation, the user's expression is recognized by an expression image recognition module.

[0070] Emoticons can be categorized into seven basic types: calm, happy, sad, angry, frustrated, and fearful. Sad, angry, frustrated, and fearful are stress-related expressions. The more frequently these five expressions appear, the more stressed the user is; the less frequently they appear, the less stressed the user is.

[0071] The preset duration is 1 minute, for example. An emotion label is assigned to each second, so as to count the frequency of stressful expressions within 1 minute. The calculation is as follows:

[0072]

[0073] Among them, N emot is the number of expression frames that appear in 1 minute, S emot is the number of target expression frames that appear within 1 minute, and M is the frequency of expression frames in a stressful state that appear within 1 minute.

[0074] The corresponding expression stress assessment results are as follows:

[0075]

[0076] Next, the body stress is assessed by collecting body stress data; and based on the body stress data, a body stress assessment result of the user is determined.

[0077] Specifically, the body stress data includes heart rate index, time domain index and frequency domain index of heart rate variability, and the level of each index is determined based on the body stress data;

[0078] Based on the level of each indicator, the score of each indicator is obtained;

[0079] Based on the scores of each indicator, the user's physical stress assessment result is determined.

[0080] The heart rate index (HR) refers to the sinus heart rate of the heart beating per minute. It represents the number of times the heart beats automatically and rhythmically per minute under the regulation of the sinoatrial node. It can also reflect the user's mood.

[0081] Heart rate variability (HRV) measures time domain metrics (RMSSD and SDNN) and frequency domain metrics (LH / HF). RMSSD is the root mean square of the difference between successive heartbeat intervals and focuses on parasympathetic nervous system activity. SDNN is the standard deviation of the heartbeat intervals over the entire cycle, reflecting overall neuroregulatory capacity. The LH / HF ratio assesses the balance between sympathetic and parasympathetic nervous systems; an elevated ratio may indicate chronic stress or excessive fatigue.

[0082] The heart rate variability (HRV) and heart rate indicators can be monitored by smart watches, and the monitored values ​​can be classified into levels according to the following table:

[0083]

[0084] For each indicator level, there is a corresponding score, which is determined according to the following table:

[0085] index healthy Moderate High high RMSSD 30 minutes 50 points 70 points 90 points SDNN 30 minutes 50 points 70 points 90 points LF / HF ratio 30 minutes / / 90 points HR 30 minutes 50 points 70 points 90 points

[0086] Based on the scores of the indicators, the user's physical stress assessment result is determined. Specifically, based on the scores of the indicators and the weights of the indicators, the user's physical stress assessment result is determined through weighted sum calculation.

[0087] First, the weights of each indicator are as follows:

[0088] RMSSD score SDNN score LF / HF ratio score HR score 28.35％ 12.29％ 16.32％ 43.04％

[0089] The user's physical stress assessment result is calculated as follows:

[0090] Physical stress assessment result = RMSSD score × 0.2835 + SDNN score × 0.1229 + LF / HF ratio score × 0.1632 + HR score × 43.04%

[0091] Next, S107 is executed to determine the user's overall stress evaluation result based on the user's psychological stress evaluation result, facial expression stress evaluation result, and physical stress evaluation result.

[0092] Specifically, based on the user's psychological stress evaluation results, facial expression stress evaluation results, and physical stress evaluation results, determine the user's psychological stress mapping score, facial expression stress mapping score, and physical stress mapping score;

[0093] The user's overall stress assessment result is determined based on the user's psychological stress mapping score, facial expression stress mapping score, physical stress mapping score, and their corresponding weights.

[0094] The user's psychological stress mapping score, facial expression stress mapping score, and physical stress mapping score are determined based on the user's psychological stress assessment results, facial expression stress assessment results, and physical stress assessment results, specifically including:

[0095] The user's psychological stress mapping score, facial expression stress mapping score, and physical stress mapping score are calculated using the following formula:

[0096]

[0097] Where S is any one of the psychological stress assessment results, facial stress assessment results, and physical stress assessment results. L is the lower limit of the level interval corresponding to any one of the psychological stress assessment results, facial expression stress assessment results, and physical stress assessment results, S U is the upper limit of the corresponding level interval, D max D is the upper limit of the score corresponding to the level range of any one of the psychological stress assessment results, facial expression stress assessment results, and physical stress assessment results. min is the corresponding lower score limit.

[0098] The following are the grade ranges and score ranges corresponding to each assessment result:

[0099]

[0100]

[0101] The following describes in detail the data of the relaxed state and the data of the stressed state respectively:

[0102] In a relaxed state:

[0103] Taking the psychological stress assessment result of 20 as an example, the corresponding level range is 14 to 28, and the score range corresponding to the level range is 0 to 25 points. Calculate the psychological stress mapping score:

[0104]

[0105] The body stress assessment result is 40, the corresponding level range is 30 to 50, and the corresponding score range is 0 to 25. Calculate the body stress mapping score:

[0106]

[0107] The result of the expression stress assessment is 5%, the corresponding level range is 0 to 5%, and the score range corresponding to the level range is 0 to 25 points. Calculate the expression stress mapping score:

[0108]

[0109] Under pressure:

[0110] Taking the psychological stress assessment result of 50 as an example, the corresponding level range is 43 to 56, and the score range corresponding to the level range is 50 to 75 points. Calculate the psychological stress mapping score:

[0111]

[0112] The body stress assessment result is 65, the corresponding level range is 50 to 70, and the corresponding score range is 25 to 50. Calculate the body stress mapping score:

[0113]

[0114] The result of the expression stress assessment is 12%, the corresponding level range is 11% to 15%, and the corresponding score range is 50 to 75 points. Calculate the expression stress mapping score:

[0115]

[0116] Next, the overall stress assessment results are calculated for the relaxation state and the stress state respectively.

[0117] The specific calculation is based on the following formula:

[0118]

[0119] For example, in a relaxed state, the psychological stress mapping score is 10.71 points, with a corresponding weight of 50%, the physical stress mapping score is 12.5 points, with a corresponding weight of 30%, and the facial stress mapping score is 25 points, with a corresponding weight of 20%. The overall stress assessment result is 10.71 × 0.5 + 12.5 × 0.3 + 25 × 0.2 = 14.105 points.

[0120] Under stress, the psychological stress mapping score is 63.46, with a corresponding weight of 50%. The physical stress mapping score is 43.75, with a corresponding weight of 30%. The facial expression solar calendar mapping score is 56.25, with a corresponding weight of 20%. The overall stress assessment result is 63.46 × 0.5 + 56.25 × 0.2 + 43.75 × 0.3 = 56.105 points.

[0121] The overall stress assessment results can also be divided into levels:

[0122]

[0123] Finally, after S107, it also includes:

[0124] Provide corresponding relaxation measures based on the overall stress assessment results;

[0125] Collect the user's physiological indicator change data;

[0126] And based on the changes in physiological indicators, adjust the intensity of corresponding relaxation measures.

[0127] Among them, relaxation measures can be of various types such as meditation, breathing training, music therapy, massage, etc.

[0128] Specifically, for example, when the overall stress assessment result is high, soothing relaxation programs such as deep breathing guidance and meditation courses are recommended; when the overall stress assessment result is in a medium range, regulating relaxation programs such as rhythmic exercise videos and relaxing music are recommended.

[0129] After providing these relaxation measures, the system monitors the user's physiological indicators, such as heart rate, skin electrical response and other data, to determine whether the user's stress state has been relieved, and thus adjusts the speed of meditation music, the rhythm of exercise videos, etc., and adjusts the intensity of relaxation measures to help users achieve intelligent stress management and achieve all-round physical and mental relaxation.
