[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0039] Some professions require long-term exposure to high-pressure environments and have high safety requirements. Therefore, in addition to physical health checks, these professions also require psychological health assessments before employees begin their jobs.

[0040] However, the relevant technologies rely on the results of self-rating scales to assess the mental health of the test subjects. When the test subjects deliberately conceal the truth, do not answer seriously, or have a low level of education and cannot understand the questions, the answer results are difficult to reflect their true mental health status.

[0041] In view of this, this embodiment provides a method for assessing psychological qualities. The psychological qualities assessment method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown is illustrated. Terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104, or it can be located in the cloud or on other network servers. Terminal 102 can be, but is not limited to, various types of environmental and physiological sensors. Server 104 can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server providing cloud computing services. Server 104 can be built into the so-called test space, or it can be independent of the test space.

[0042] In one exemplary embodiment, such as Figure 2 As shown, a method for assessing psychological qualities is provided, which is then applied to... Figure 1 Taking server 104 as an example, the explanation includes the following S201-S202. Wherein:

[0043] S201, after adjusting the environmental parameters of the test space from non-pressure conditions to the first pressure conditions, perform visual tracking tests on the target object and obtain the first target response data.

[0044] In one embodiment, the test space can be an enclosed space that integrates an environmental parameter control system and a response data acquisition system, where the environmental parameters represent multidimensional parameters in the test space that are related to and adjustable from the environment.

[0045] For example, environmental parameters may include light parameters (light color, light intensity), sound parameters (sound intensity, sound type), temperature parameters, and air parameters (odor type, odor concentration, oxygen concentration).

[0046] Optionally, the testing space may be equipped with adjustable light sources, surround sound, air conditioning, nebulizers, and physiological data acquisition devices (such as cameras, wearable physiological recorders, etc.).

[0047] In an exemplary embodiment, the first pressure condition is used to simulate a complex pressure source in the working scenario of a target object (e.g., a railway driver). The non-pressure condition represents a control condition corresponding to the first pressure condition, and the environmental parameters corresponding to the non-pressure condition are used to simulate the environmental state that puts the target object in a comfortable state.

[0048] It should be noted that both the first stress condition and the non-stress condition can be flexibly adjusted according to the target's age, work intensity, and physical condition, and this application embodiment does not limit this.

[0049] For example, the environmental parameters corresponding to the first pressure condition could be 500 lux of blue light, 70 dB of high-frequency white noise, a temperature of 18°C, and an oxygen content of 18%. The environmental parameters corresponding to the non-pressure condition could be 300 lux of warm yellow light, 50 dB of soothing music, a temperature of 25°C, an oxygen content of 21%, and 0.1% of irritating odor.

[0050] Optionally, visual tracking tests can be performed by tracking the eye movements of the target object during cognitive task games or self-assessment scale responses using binocular TOF (Time of Flight) cameras. The cognitive task games can be CPT (Continuous Performance Test) or MOT (Multiple Target Tracking).

[0051] For example, the first target response data represents the set of objective data collected during the process of adjusting the environmental parameters of the test space from non-stress conditions to first stress conditions, reflecting the target object's response to the visual tracking test. The first target response data includes first target multimodal physiological data and first target test result data. The first target multimodal physiological data represents the physiological signals of the target object; for example, it may include eye-tracking data, HRV (Heart Rate Variability), GSR (Galvanic Skin Response), etc. The first target test result data represents the completion status of the cognitive task game and the responses to the self-assessment scale in the visual tracking test.

[0052] In some embodiments, before the target object is put into service, it can first enter the test space. The response data acquisition system in the test space can collect information from the target object to determine the first pressure condition and non-pressure condition corresponding to the target object. The environmental parameter control system first adjusts the environmental parameters to the non-pressure condition and then to the first pressure condition. When the environmental parameters are the first pressure condition, the target object is subjected to visual tracking test to obtain the first target multimodal physiological data and the first target test result data of the target object.

[0053] S202, Based on the first target response data, conduct a psychological quality assessment of the target object.

[0054] For example, the psychological quality assessment result of the target object can be determined based on the first target response data and a preset response threshold. The preset response threshold includes a threshold corresponding to each modality in the first target multimodal physiological data and a threshold corresponding to the first target test result data.

[0055] The aforementioned psychological quality assessment method, after adjusting the environmental parameters of the testing space from non-stress conditions to a first stress condition, conducts a visual tracking test on the target subject and acquires first target response data. This first target response data includes first target multimodal physiological data and first target test result data. Based on this first target response data, the psychological quality of the target subject is assessed. This scheme, by dynamically adjusting the environmental conditions of the testing space and simultaneously conducting visual tracking tests, can acquire objective physiological and behavioral response data of the target subject during stress changes, providing a more dynamic and realistic basis for psychological quality assessment, thereby improving the accuracy and reliability of the assessment.

[0056] In one embodiment, psychological qualities include stress resilience, which reflects the target individual's ability to withstand stressful environments and recover after stress is relieved. Figure 3 As shown, the above S202 includes the following S301-S305.

[0057] S301, during the process of adjusting the environmental parameters of the test space from the first pressure condition to the non-pressure condition, visual tracking test is performed on the target object, and second target response data is obtained.

[0058] For example, during the pressurization phase, the environmental parameters of the test space are adjusted from non-pressure conditions to the first pressure conditions, and a visual tracking test is performed on the target object. Subsequently, during the depressurization phase, while adjusting the environmental parameters of the test space from the first pressure conditions to non-pressure conditions, a visual tracking test is performed on the target object.

[0059] The second target response data refers to the set of objective data collected on the target object's response to the visual tracking test during the process of adjusting the environmental parameters of the test space from the first pressure condition to the non-pressure condition. The second target response data includes second multimodal physiological data and second test result data.

[0060] It should be noted that the time periods corresponding to the pressure-increasing phase and the decompression phase can be the same or different. Furthermore, the difficulty of the cognitive task game in the visual tracking test corresponding to the pressure-increasing phase and the decompression phase can be the same or different. This application embodiment does not limit this.

[0061] S302, Obtain reference response data for the target object.

[0062] The reference response data is obtained during visual tracking tests on the target object under non-stress conditions in the test space. Specifically, the reference response data represents the set of objective data collected on the target object's response to the visual tracking test under non-stress conditions in the test space. The reference response data may include reference multimodal physiological data and reference test result data.

[0063] For example, the difficulty of the cognitive task game in the visual tracking test process when the target object is under non-stress conditions in the test space is lower than the difficulty corresponding to the stress and de-stress phases.

[0064] S303, determine the compressive strength of the target object based on the first target response data and the reference test result data.

[0065] Among them, stress resistance is used to reflect the ability of a target object to maintain psychological and behavioral stability under the first stress condition of the environmental parameters in the test space.

[0066] Optionally, the stress resistance of the target object can be determined by comparing the first target test result data in the first target response data with the reference test results.

[0067] S304. Determine the pressure recovery elasticity of the target object based on the second target response data and the reference response data.

[0068] Among them, pressure recovery elasticity is used to reflect the speed and extent to which the physiological state and behavioral performance of the target object recover after the environmental parameters of the test space recover from the first pressure condition to the non-pressure condition.

[0069] For example, the stress recovery elasticity of a target object can be determined by comparing second multimodal physiological data with reference multimodal physiological data, and by comparing second test result data with reference test result data.

[0070] S305, based on the assessment results of the pressure resistance and pressure recovery elasticity, determines the pressure adaptability of the target object.

[0071] In one embodiment, the stress resistance and stress recovery elasticity can be quantified, and the quantified results can be normalized and then weighted and aggregated to obtain stress adaptability data. Then, based on the preset stress adaptability threshold and the stress adaptability data, the evaluation result of the stress adaptability of the target object can be determined.

[0072] For example, the higher the stress adaptability data value, the better the target's stress adaptability. Correspondingly, if the stress adaptability data value is higher than the preset stress adaptability threshold, the target's stress adaptability assessment result can be determined as passing, and it is recommended that they be put on the job; conversely, if the stress adaptability data value is not higher than the preset stress adaptability threshold, the target's stress adaptability assessment result can be determined as failing, and it is not recommended that they be put on the job.

[0073] This embodiment simultaneously collects the target object's first target response data during the pressurization phase, the second target response data during the depressurization phase, and the reference response data corresponding to non-pressurization conditions. It then quantifies the target object's stress resistance under pressure by using the first target response data and the reference response data, and quantifies the target object's pressure recovery elasticity by using the second target response data and the reference response data. This achieves a comprehensive, dynamic, and objective assessment of pressure adaptability, overcoming the shortcomings of traditional assessment methods that cannot reflect dynamic stress adaptation and recovery capabilities. It provides more relevant data for assessing the psychological qualities of high-pressure positions such as railway drivers, significantly improving the occupational suitability and accuracy of the assessment results.

[0074] Based on the above embodiments, such as Figure 4 As shown, the above S304 includes the following S401-S402.

[0075] S401, determine the recovery time based on the second target response data and the reference response data.

[0076] The recovery time includes a first recovery time and / or a second recovery time; the first recovery time represents the time required for the second target multimodal physiological data to recover to the reference multimodal physiological data, and the second recovery time represents the time required for the second target test result data to recover to the reference test result data.

[0077] For example, for each modality, there is a corresponding first recovery time, which is the longest of the time required to recover to the reference multimodal physiological data corresponding to the response modality.

[0078] S402, determine the pressure recovery elasticity of the target object based on the recovery time and the duration corresponding to the recovery time period.

[0079] The recovery period is the time during which the environmental parameters of the test space are adjusted from the first pressure condition to the non-pressure condition.

[0080] For example, the process of determining the pressure recovery elasticity (REI) of a target object based on the recovery time and the duration corresponding to the recovery time period can be expressed as the following formula (1).

[0081] REI = 1 - (T recovery / T total (1)

[0082] Among them, T recovery T represents the recovery time. In cases where the recovery time includes both a first recovery time and a second recovery time, T represents the recovery duration. recovery Here, T is the larger of the first recovery time and the second recovery time mentioned above; when the recovery time is the first recovery time, T... recovery This is the first recovery time; when the recovery time is the second recovery time, T recovery This is the second recovery time, T. total This indicates the duration of the recovery period.

[0083] This embodiment determines the pressure recovery elasticity of the target object based on the recovery time and the duration corresponding to the recovery period, thereby quantifying the pressure recovery elasticity in pressure recovery capability and further improving the objectivity and scientific nature of the pressure adaptability assessment results.

[0084] For example, such as Figure 5 As shown, the above S303 includes the following S501-S502.

[0085] S501, for each modality, determine the offset of the physiological data of the modality in the first target response data relative to the physiological data of the modality in the second target response data.

[0086] For example, the offset is used to reflect the difference between the physiological data of a certain modality in the first target response data and the physiological data of the same modality in the reference response data.

[0087] Optionally, the offset can be the difference between the physiological data of a certain modality in the first target response data and the physiological data of the same modality in the reference response data. Alternatively, the offset can be the rate of change of the physiological data of a certain modality in the first target response data relative to the physiological data of the same modality in the reference response data.

[0088] S502, determine the stress resistance of the target object based on the offset corresponding to each mode, the first task success rate in the first target test result data, and the reference task success rate in the reference test result data.

[0089] The task success rate represents the ratio of the number of times the target subject successfully completes a cognitive task game to the total number of attempts.

[0090] For example, in a cognitive task game, the difficulty of each task can be the same or different. When the difficulty of each task is different, a corresponding weight can be assigned to each task according to the difficulty level. For example, for a task with a difficulty level of 1 (the easiest), its weight can be 0.5, that is, successfully completing a task with a difficulty level of 1 once is recorded as 0.5 times.

[0091] Optionally, the average offset can be calculated based on the offset corresponding to each mode; then, the quantitative result of the target object's resilience can be obtained based on the average offset, the success rate of the first task, and the success rate of the reference task.

[0092] In an exemplary embodiment, the process of determining the compressive strength SRI of a target object can be expressed as the following formula (2).

[0093] SRI = (P press / P base ) * (1 - |ΔPhysio press |) (2)

[0094] Among them, P press P represents the success rate of the first task. base ΔPhysio represents the reference task success rate. press This represents the average offset.

[0095] This embodiment determines the stress resistance of the target object based on the offset corresponding to each modality, the first task success rate in the first target test result data, and the reference task success rate in the reference test result data, thereby quantifying the stress resistance in stress recovery capability. At the same time, since multimodal physiological data are the instinctive reflection of the target object and have the characteristic of being difficult to control autonomously, the objectivity and scientificity of the stress adaptability assessment results are further improved.

[0096] In one exemplary embodiment, based on the above embodiments, psychological qualities also include focus, which reflects the degree of concentration of the target subject during cognitive task games or self-assessment scales. Figure 6 As shown, the above S202 includes the following S601-S603.

[0097] S601, based on the first target fixation data, determine the average fixation duration of the target object during the pressure period.

[0098] For example, the first target multimodal physiological data includes first target gaze data, which represents gaze-related data in the eye movement data of the target object. For example, the first target gaze data may include the duration of each gaze point, the distribution of gaze point positions, etc.

[0099] The pressurization period is the time period during which the environmental parameters of the test space are adjusted from non-pressure conditions to the first pressure condition.

[0100] In one embodiment, gaze data of the first target can be acquired using a binocular TOF camera, and then the average gaze duration of the target object during the pressurization period can be determined according to the following formula (3). .

[0101] (3)

[0102] in, Let I represent the dwell time at the i-th fixation point, where I is the total number of fixation points.

[0103] S602, based on the first target scan data, determine the scan speed of the target object during the pressure period.

[0104] For example, the first target multimodal physiological data includes first target saccade data, which represents data related to saccades in the eye movement data of the target object. For example, the first target saccade data may include the number of saccades, the total displacement of the saccades, the time spent on each saccade, etc.

[0105] In one embodiment, the scanning data of the first target can be obtained by a binocular TOF camera, and then the scanning speed of the target object during the pressurization period can be determined according to the following formula (4). .

[0106] (4)

[0107] in, Indicates the total displacement of the scan. Let m represent the time taken for the m-th scan, and M represent the total number of scans.

[0108] S603 determines the assessment results of the target object's focus under the first pressure condition based on the average fixation duration, saccade speed, and first target test results data.

[0109] For example, a longer average fixation duration and a faster saccade speed indicate that the target object is more focused during the stress period; conversely, a shorter average fixation duration and a slower saccade speed indicate that the target object is more distracted during the stress period.

[0110] Optionally, the assessment result of the target object's focus under the first pressure condition can be determined by comparing the average fixation duration with a preset fixation duration threshold, comparing the saccade speed with a preset saccade speed threshold, and comparing the first target test result data with a preset test result data threshold.

[0111] Furthermore, if the assessment result of the target's focus under the first pressure condition indicates that the target's focus is good, it means that the target has passed the focus assessment and is recommended to be employed; conversely, if the assessment result of the target's focus under the first pressure condition indicates that the target's focus is poor, it means that the target has failed the focus assessment and is not recommended to be employed.

[0112] This embodiment calculates the average fixation duration and saccade speed during the pressure period by acquiring first target fixation data and first target saccade data, and quantifies focus by combining the first target test results data. This achieves an objective quantitative assessment of focus under the first pressure condition. Since the first target fixation data and first target saccade data are difficult to control autonomously, this effectively overcomes the technical defects of traditional assessments that rely on self-rating scales and cannot accurately reflect attention concentration. It also avoids the impact of the target's low level of education on the assessment results, improving the reliability and accuracy of focus assessment. This provides scientific and practical technical support for the psychological quality assessment required for high-pressure professions such as railway drivers.

[0113] Optional, such as Figure 7 As shown, the above S603 includes the following S701-S703.

[0114] S701, based on the difference between the first ratio and the second ratio, determine the tracking efficiency of the target object during the visual tracking test within the pressurization period.

[0115] The first ratio is the ratio between the number of successful tasks and the total number of tasks, and the second ratio is the ratio between the cumulative time of task failures and the duration of the pressure period.

[0116] For example, tracking efficiency is used to represent the effectiveness of a target object in a visual tracking task; the higher the tracking efficiency, the higher the effectiveness.

[0117] In one embodiment, tracking efficiency The calculation process can be expressed as the following formula (5).

[0118] (5)

[0119] Where x is the weight corresponding to the first ratio, usually x=1, and y is the weight corresponding to the second ratio, usually y=0.5. Indicates the number of times the task was successful. Indicates the total number of tasks. This indicates the cumulative time taken for failures. This indicates the duration of the pressurization period.

[0120] S702 normalizes the average fixation duration, saccade speed, and tracking efficiency.

[0121] For example, since average fixation duration, saccade speed, and tracking efficiency are indicators of different dimensions, they can be normalized by converting them into standardized data in the 0-1 range, thereby eliminating the influence of dimensions.

[0122] S703 performs weighted aggregation of the normalized average fixation duration, saccade speed, and tracking efficiency to obtain the evaluation results of the target object's focus under the first pressure condition.

[0123] Optionally, the normalized average fixation duration, saccade speed, and tracking efficiency can be weighted and aggregated according to preset weights to obtain the evaluation results of the target object's focus under the first pressure condition.

[0124] It should be noted that the weights of average fixation duration, saccade speed and tracking efficiency can be flexibly adjusted according to actual conditions such as evaluation criteria and the workload of the target object, and this application does not impose any restrictions on this.

[0125] For example, the weight corresponding to the normalized average fixation duration can be 0.4, the weight corresponding to the normalized saccade speed can be 0.3, and the weight corresponding to the normalized tracking efficiency can be 0.3.

[0126] This embodiment first calculates the average fixation duration, saccade speed, and tracking efficiency. Then, it performs weighted aggregation on the normalized average fixation duration, saccade speed, and tracking efficiency to obtain the assessment results of the target object's focus under the first pressure condition.
