DETAILED DESCRIPTION

[0018] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0019] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0020] Reference Figure 1 An embodiment of the present invention provides a psychological assessment method based on virtual reality, comprising the following steps: S1: receiving a selection instruction input by a user, wherein the selection instruction is used to select a VR painting scene; S2: sending the corresponding VR painting scene to the VR device worn by the user according to the selection instruction; S3: Sending a drawing prompt to the VR device worn by the user, wherein the drawing prompt is used to prompt the user to draw a tree in the corresponding VR drawing scene; S4: Sending image feature information of the tree to the VR device worn by the user for the user to select and draw; the image feature information includes the shape, size, and color of the crown, trunk, and roots; S5: receiving and temporarily saving the tree painting image input by the user; S6: performing psychological scoring using a linear regression model based on the image feature information in the tree painting image to obtain a scoring value; S7: Compare the scoring value with a set threshold to obtain a psychological assessment result.

[0021] As described in step S1 above, the VR painting scene can have multiple different scenes for the user to choose from. The user can select the scene he likes through the VR device, which can reduce the psychological burden of the user being tested and eliminate the psychological defense of the user being tested, which is conducive to improving the authenticity of the test results. After the selection is completed, the VR device sends the selection instruction input by the user to the first receiving module; the first receiving module receives the selection instruction input by the user; As described in step S2 above, the first sending module transmits the corresponding VR painting scene to the VR device worn by the user; a three-dimensional immersive scene that meets the user's selection is generated on the VR device, and the user can freely adjust the viewing angle and roam in the VR painting scene.

[0022] As described in the above step S3, the prompt module sends a drawing prompt to the VR device worn by the user. The prompt method may include voice prompts or displaying relevant prompt images in the painting scene where the user is located. The drawing prompt is used to prompt the user to draw a tree in the corresponding VR painting scene; specifically, for example: through the VR helmet and the voice function of the VR tree drawing software, the user is prompted to draw a tree at a specific location in the VR painting scene; or by displaying arrows and text in the VR painting scene where the user is located to prompt the user to draw a tree at the corresponding location, thereby achieving the purpose of prompting and guiding the user to conduct the test.

[0023] As described in step S4 above, the feature module transmits the tree's image feature information to the user's VR device, displaying a list of available tree features within the user's VR drawing scene for selection and drawing. The user can use the VR controller to freely select and draw. Specifically, the image feature information includes the shape, size, and color of the crown, trunk, and roots. Users can then create their own 3D tree drawings based on their own ideas.

[0024] As described in step S5 above, the temporary storage module receives and temporarily stores the tree painting image input by the user to facilitate subsequent evaluation.

[0025] As described in step S6 above, the features of each part of the tree in the tree painting image represent different parameters, and the scoring module performs psychological scoring based on the image feature information in the tree painting image through the established and tested linear regression model to obtain a scoring value; As described in step S7 above, the conclusion module compares the score with a set threshold to produce a psychological assessment result. For example, if the score is above or equal to the threshold, it indicates the presence of certain psychological problems; if it is below the threshold, it indicates a psychologically healthy state. Furthermore, multiple thresholds can be used to classify psychological problems into different degrees, such as depression, which can be categorized as no depression, mild, moderate, or severe.

[0026] This embodiment adopts a non-verbal VR painting assessment method, and the painting space is transformed from a two-dimensional flat form to a three-dimensional form, which brings an immersive painting experience, allowing the test subject to become more focused during the creative process and better avoid external interference; and the method of painting trees in the VR scene makes it less likely for the test subject to perceive the purpose of the test, which can reduce the psychological burden and eliminate psychological defenses, and is conducive to improving the authenticity of the test results and making the assessment results more accurate; and the method of using a linear regression model based on the image feature information in the tree painting image to perform psychological scoring makes the assessment more efficient, accurate and stable, and reduces manual work.

[0027] In some embodiments, the linear regression model is: Among them, X is the image feature of the tree, Y is the score, β is the parameter; ε is the error value.

[0028] In this embodiment, the establishment of the linear regression model includes the following steps: 1. Create a VR painting test database Recruit a group of subjects to take the SDS questionnaire survey first, and obtain the test result Y value of the SDS questionnaire, that is, the SDS score Y is the dependent variable, and this value will be marked as Y below. (SDS) Then, VR painting test is performed to obtain the image feature X of the tree, and Y (SDS) When both the β and X values are obtained, the β value can be obtained using the multiple linear regression model as follows; After recruiting multiple batches of subjects to conduct VR painting tests, a VR test sample database can be established.

[0029] 2. Evaluate model coefficients Recruit a new group of subjects and directly use VR painting software to test the tree image feature X value. Substitute the obtained tree image feature X value and the β value obtained in step 1 into the multivariate linear regression model to obtain the test result Y value, which will be marked as Y below. (VR) .

[0030] 3. Obtain VR painting result evaluation criteria Y (SDS) and Y (VR) Compare the results of the VR tree drawing to verify the consistency between the results of the SDS questionnaire. Repeat steps 1 and 2 to make the two Y values as close as possible. Ideally, when the two are equal, that is, Y (SDS) =Y(VR) , which shows that the VR painting method can also effectively assess the degree of human psychological depression.

[0031] Set the scoring threshold Y for VR painting software （R） , so that VR painting software can automatically give VR painting test scores and psychological assessment results without the need for manual intervention. (VR) >Y （R） If the test result is negative, it indicates that the test subject may have certain mental health problems. Otherwise, the test subject's mental health is normal or good.

[0032] In this embodiment, the linear regression model is first established and tested by collecting test data of a large number of test subjects and evaluation results of corresponding psychological experts, and then applied to accurately obtain the scoring score to ensure accurate evaluation.

[0033] In some embodiments, after step S5 of receiving and temporarily saving the tree painting image input by the user, the following steps are included: S51: receiving an edit and view instruction input by a user; S52: Sending the temporarily saved tree painting image to the VR device worn by the user for modification or viewing of the tree painting image.

[0034] In this embodiment, the user can modify and view the tree painting image drawn by himself at any time.

[0035] In some embodiments, before step S1 of receiving a selection instruction input by a user, the following steps are included: S11: Receive basic personal information input by the user; S12: storing the personal basic information as user historical account information; After step S7 of comparing the scoring value with a set threshold value to obtain a psychological assessment result, the following steps are included: S71: Storing the evaluation result and the tree painting image corresponding to the evaluation result in the corresponding user history account information.

[0036] As described in steps S11 to S12 above, before taking the test, the user first registers personal information and creates an account. The third receiving module receives the user's corresponding basic personal information; the account storage module stores the corresponding personal information as the user's historical account information, managing one account per person to ensure the user's privacy and security.

[0037] As described in step S71 above, once the psychological assessment is complete, i.e., the results are obtained, the account storage module stores the results and the corresponding tree drawing image in the corresponding user's historical account information. The user or authorized psychologist can access the user's account information at any time to facilitate management and provide advice to the patient.
