Description

Technical Field

[0001] This invention relates to a virtual reality-based method for interacting with the emotions and cognition of perinatal women, and also to a corresponding system for interacting with the emotions and cognition of perinatal women, belonging to the field of cognitive interaction technology. Background Technology

[0002] The perinatal period is a unique time for women, and psychological changes caused by hormonal fluctuations, social role pressures, and childbirth pain significantly impact the emotions and cognition of pregnant and postpartum women. Clinical and empirical studies have shown that perinatal women are significantly more likely to experience emotional problems such as depression, anxiety, stress, and fear, as well as cognitive functions such as memory, attention, visuospatial and executive functions. Virtual reality technology, using virtual people or objects to help patients alleviate their resistance to the outside world and enhance the multi-sensory, immersive, interactive, and imaginative aspects of interventions, can help achieve better intervention outcomes.

[0003] Chinese invention application CN113782154A discloses a maternal and infant mental health management system. The system includes a doctor's client receiving a first instruction to select a pregnant or postpartum patient and issue an assessment form; receiving a third instruction to view the assessment results of each assessment form and provide a treatment plan; an internet hospital platform connecting to the doctor's client, receiving assessment forms in English, and associating the assessment forms with the corresponding maternal or postpartum patient's client account; receiving the assessment results of each assessment form; and the maternal or postpartum patient's client connecting to the internet hospital platform. The maternal or postpartum patient's client receives a second instruction, selects an associated assessment form, and begins the assessment to obtain the results. This system allows doctors to promptly issue assessment forms to pregnant or postpartum patients, and the assessment results of pregnant or postpartum patients can be promptly transmitted to doctors for review, enabling doctors to promptly develop treatment plans. This allows for the timely detection of maternal and infant mental health issues and the implementation of comprehensive maternal and infant mental health management.

[0004] However, most of the aforementioned systems operate on a traditional medical model, with doctors independently issuing assessments and treatment plans. They lack follow-up monitoring and personalized interventions, and their presentation is often monotonous and lacks focus on user experience, particularly for women during the perinatal period. Furthermore, research has found that the incidence of cognitive impairment among pregnant and postpartum women is around 30%–50%, and existing technologies pay limited attention to the cognitive aspects of women during the perinatal period. Summary of the Invention

[0005] The primary technical problem to be solved by this invention is to provide a method for interaction between emotions and cognition in perinatal women based on virtual reality.

[0006] Another technical problem to be solved by the present invention is to provide a virtual reality-based interactive system for the emotions and cognition of women during the perinatal period.

[0007] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0008] According to a first aspect of the present invention, a method for interaction between perinatal women's emotions and cognition based on virtual reality is provided, comprising the following steps:

[0009] Acquire user's emotion and cognitive assessment data; wherein, the emotion and cognitive assessment data includes the user's scores on multiple emotional dimensions and multiple cognitive dimensions;

[0010] Based on the user's emotion and cognitive assessment data, emotion interaction tasks and / or cognitive interaction tasks are matched from a preset task library to form an interaction task combination; wherein, the preset task library includes multiple emotion interaction tasks and multiple cognitive interaction tasks, and each emotion interaction task and each cognitive interaction task is matched with parameters of a preset virtual scenario library to assign different virtual scenarios to each emotion interaction task and each cognitive interaction task respectively.

[0011] Based on the aforementioned combination of interactive tasks, a personalized emotional and cognitive interaction scheme for perinatal women is obtained.

[0012] Based on the personalized perinatal women's emotional and cognitive interaction scheme, obtain the user's behavioral response data when engaging in emotional and cognitive interactions;

[0013] Based on the user's behavioral response data, the system provides feedback to the user on the results of the perinatal women's emotional and cognitive interactions during this period and ends the perinatal women's emotional and cognitive interactions during this period.

[0014] The user's emotional and cognitive assessment data are acquired again to rematch the interaction task combination and conduct the next cycle of perinatal female emotional and cognitive interaction until the user's emotional and cognitive assessment data reaches the preset expected level.

[0015] Preferably, the user's multiple emotional dimensions include at least one or more of depression, anxiety, stress, and fear, and the user's multiple cognitive dimensions include at least one or more of memory, attention, visuospatial function, and executive function.

[0016] Each of the emotional dimensions and each of the cognitive dimensions corresponds to a set of scales, and each of the emotional dimensions corresponds to a different emotional interaction task, and each of the cognitive dimensions corresponds to a different cognitive interaction task.

[0017] Preferably, the plurality of emotional interaction tasks include: meditation relaxation task, systematic desensitization task, emotional catharsis task, rational emotion task, and attention game task;

[0018] The multiple cognitive interaction tasks include: object memory task, hit and dodge task, and search and puzzle task;

[0019] Among them, depression corresponds to meditation relaxation task and attention game task, anxiety corresponds to meditation relaxation task and rational emotion task, stress corresponds to meditation relaxation task and emotional catharsis task, fear corresponds to meditation relaxation task and systematic desensitization task, memory corresponds to object memory task, attention corresponds to hit and dodge task, and visuospatial and executive functions correspond to search and puzzle task.

[0020] Preferably, the personalized perinatal female emotional and cognitive interaction scheme is obtained through the following methods:

[0021] Based on the user's emotion and cognition assessment data, obtain the user's emotional dimension that needs improvement and / or cognitive dimension that needs to be enhanced;

[0022] Based on the user's emotional dimension to be improved and / or cognitive dimension to be enhanced, corresponding emotional interaction tasks and / or cognitive interaction tasks are matched from the preset task library to form an interaction task combination.

[0023] Based on the severity of the user's emotional dimension to be improved and / or cognitive dimension to be enhanced, obtain the interaction order of all interaction tasks in the interaction task combination and the interaction duration of each interaction task.

[0024] The interaction cycle is determined based on the number of interaction dimensions and the interaction duration of each interaction task.

[0025] The interactive task combination, the interaction order of all interactive tasks, the interaction duration of each interactive task, and the current interaction cycle together constitute the personalized perinatal female emotional and cognitive interaction scheme.

[0026] Preferably, the interaction period is set to a preset number of days. When the user begins the interaction with the personalized perinatal female emotion and cognition interaction scheme, the number of days of interaction increases by one every day until the number of days of interaction equals the interaction period, at which point the perinatal female emotion and cognition interaction of this period ends.

[0027] Preferably, the step of providing feedback to the user on the perinatal emotional and cognitive interaction results of the current cycle based on the user's behavioral response data includes:

[0028] The system acquires the user's daily behavioral response data and displays the daily interaction results. The daily interaction results display includes the number of interactions and interaction duration for each emotional interaction task, as well as the number of interactions, interaction duration, and interaction score for each cognitive interaction task.

[0029] Based on the daily interaction results displayed during this period, the user's emotional and cognitive changes during this period are displayed to provide feedback to the user on the emotional and cognitive interaction results of women during this perinatal period.

[0030] Preferably, the perinatal female emotion and cognition interaction method further includes:

[0031] Plant seeds are obtained and provided to the user before the user begins emotional and cognitive interaction;

[0032] When the user engages in the personalized perinatal female emotional and cognitive interaction program, they receive a water droplet for each completed interaction task, which can be used to water the plant seeds.

[0033] According to a second aspect of the present invention, a virtual reality-based interactive system for perinatal women's emotions and cognition is provided, comprising:

[0034] The storage unit has a built-in preset scale, preset task library and preset virtual scenario library; wherein, the preset task library includes multiple emotional interaction tasks and multiple cognitive interaction tasks, and each emotional interaction task and each cognitive interaction task is matched with parameters of the preset virtual scenario library to assign different virtual scenarios to each emotional interaction task and each cognitive interaction task respectively.

[0035] An assessment unit, connected to the storage unit, is used to assess the user's emotions and cognition based on the preset scale, thereby generating a user profile.

[0036] The output unit is connected to the storage unit and the evaluation unit to output a personalized emotional and cognitive interaction scheme for perinatal women based on the preset task library and the preset virtual scenario library and according to the user profile.

[0037] An interaction unit, connected to the output unit, receives the personalized perinatal female emotional and cognitive interaction scheme and interacts with the user emotionally and cognitively.

[0038] An observation unit is connected to the interaction unit to acquire behavioral response data of the user during emotional and cognitive interactions; the observation unit is also connected to the storage unit to store the behavioral response data in the storage unit.

[0039] Preferably, the perinatal female emotion and cognition interaction system further includes:

[0040] A display unit, connected to the observation unit, is used to display the user's daily interaction results.

[0041] According to a third aspect of the present invention, a virtual reality-based system for interacting with the emotions and cognition of women during the perinatal period is provided, comprising a processor and a memory, wherein the processor reads a computer program in the memory to execute the aforementioned method for interacting with the emotions and cognition of women during the perinatal period.

[0042] Compared with the prior art, the present invention has the following technical effects:

[0043] 1. Integrated Assessment and Intervention Based on Virtual Reality Technology. Virtual reality technology is characterized by interactivity, immersion, and imaginative features. Utilizing virtual reality technology for psychological intervention can help promote user motivation and compliance. In addition to developing emotional and cognitive intervention training in a virtual reality scenario, this embodiment also incorporates the assessment process into the virtual reality scenario through an engaging story background, thus solving the problem of the separation between the assessment and intervention processes.

[0044] 2. Intervention programs that consider the interaction of different influencing factors. According to the literature review, pregnant women with different characteristics have varying risks of emotional and cognitive impairment. Considering the interaction between the pregnant woman's emotions, cognition, and past medical history, a comprehensive and personalized intervention program can be generated, making it more targeted.

[0045] 3. Technological Transformation and Development of Psychotherapy Theories. Based on classic psychotherapy theories such as cognitive behavioral therapy, rational emotive behavior therapy, and mindfulness, more realistic and vivid intervention training can be developed in virtual reality environments through the manipulation of virtual people and virtual objects, such as emotional catharsis and scenario simulation. Furthermore, compared to traditional psychotherapy methods, virtual reality technology provides users with a more private and secure environment, which is conducive to the expression and release of individual emotions.

[0046] 4. Development of targeted cognitive enhancement programs. Cognitive processing typically involves the input and output of external information. For example, in explicit memory, memory encoding is required before retrieval, necessitating the participation and utilization of multiple sensory information. Immersive virtual reality systems, by providing a panoramic visual experience and richer auditory and tactile sensations, allow users to engage multiple senses in training within a highly realistic virtual environment, resulting in more significant cognitive training effects.

[0049] Figure 3 This is a structural diagram of a virtual reality-based perinatal female emotion and cognition interaction system provided in the third embodiment of the present invention. Detailed Implementation

[0050] The technical content of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0051] This invention aims to focus on and improve the emotional state and cognitive function of perinatal women. Based on virtual reality technology, it uses scales to screen users for emotional and cognitive impairments and generates corresponding intervention plans. In this intervention plan, different interactive methods are developed in virtual reality scenarios for the four dimensions of emotional state (depression, anxiety, stress, and fear) and the three dimensions of cognitive function (memory, attention, and visuospatial and executive functions). After each intervention cycle, the system will automatically generate the next stage's intervention plan based on the intervention effect.

[0052] In different embodiments of this invention, five virtual reality interactions for emotional intervention are mainly involved: meditation relaxation, systematic desensitization, emotional catharsis, rational emotive behavior, and attention games; and three virtual reality interactions for cognitive intervention: object memory tasks, hit-and-dodge tasks, and find-and-puzzle tasks. By combining theories of positive psychology, cognitive behavioral therapy, and mindfulness from traditional psychotherapy, and after being modified, adjusted, and verified by professionals, this intervention program is diverse, professional, targeted, and effective.

[0053] First Embodiment

[0054] like Figure 1 As shown, the first embodiment of the present invention provides a method for interaction between perinatal women's emotions and cognition based on virtual reality, specifically including steps S1 to S6:

[0055] S1: Obtain user's emotional and cognitive assessment data.

[0056] Specifically, the first step is to guide users on how to correctly wear and use virtual reality (VR) devices. In one embodiment of the invention, the VR device consists of a head-mounted display, a wireless controller, and a positioning system. After wearing the head-mounted display, the user will be immersed in a 360° omnidirectional stereoscopic virtual reality environment and complete relevant scene tasks through the controller.

[0057] Virtual scenes and characters are generated within a virtual reality environment. Users enter a welcome screen and are informed of the system rules. For example, the first VR scene includes a welcome screen, followed by a rest scene with calm and pleasant background music playing, where participants are informed of the game rules by NPCs.

[0058] Users fill in their basic personal information, including age, past medical history, whether they have given birth, duration of pregnancy, and basic information about the newborn, which is recorded as P in the storage unit. Then, users enter an assessment page; for example, the assessment page scene includes a virtual living room with a sofa, plants, carpet, wooden floor, and bookshelves filled with colorful books. An NPC will provide a questionnaire and guide users on how to answer the questions, such as: "The following questions will measure your personal traits and recent life situation, and generate a personalized flower for you based on this." This personalized flower is used for subsequent plant cultivation to increase user initiative and enthusiasm (explained in detail below).

[0059] In this embodiment, the questionnaire is divided into two parts: emotional assessment and cognitive assessment, with each dimension numbered separately. Emotional states can be categorized into four emotional dimensions: depression (numbered a), anxiety (numbered b), stress (numbered c), and fear (numbered d). Cognitive functions can be categorized into three cognitive dimensions: memory (numbered e), attention (numbered f), and visuospatial and executive functions (numbered g). Each dimension corresponds to a set of assessment scales within the evaluation unit. The specific correspondence is as follows:

[0060] The Edinburgh Depression Scale (EPDS) was used to screen for symptoms of type A depression.

[0061] Screening for Category B anxiety symptoms was performed using the Perinatal Anxiety Screening Scale (PASS).

[0062] The Perceived Stress Scale (PSS) was used to screen for Category C stress symptoms.

[0063] The Childbirth Fear Scale (CAQ) was used to screen for Category d fear symptoms.

[0064] The measurements of e-class memory, f-class attention, and g-class visuospatial and executive functions were performed using the corresponding cognitive function subscales of the Montreal Cognitive Assessment (MoCA).

[0065] In this embodiment, scores for each dimension are calculated based on the user's response text, and the severity is marked as D1. The above assessment scales are all classic psychological scales. Scores for each scale are collected and obtained. The presence of emotional and cognitive problems is determined based on the comparison of critical values ​​or the norm transformation algorithm. For example, the critical value of the Edinburgh Depression Scale is 9 points, 9-12 points is mild depression, and 13-30 points is moderate to severe depression.

[0066] Understandably, after completing the user's emotional and cognitive assessment, it will be possible to identify which dimensions of the user need improvement. Furthermore, these dimensions can be ranked according to the severity marked in D1, which can then be used to develop personalized emotional and cognitive interaction plans for perinatal women.

[0067] S2: Based on the user's emotion and cognitive assessment data, match emotion interaction tasks and / or cognitive interaction tasks from the preset task library to form a combination of interaction tasks.

[0068] In this embodiment, the preset task library includes multiple emotional interaction tasks and multiple cognitive interaction tasks. Specifically, the multiple emotional interaction tasks include: meditation and relaxation tasks, systemic desensitization tasks, emotional catharsis tasks, rational emotion tasks, and attention game tasks. The multiple cognitive interaction tasks include: object memory tasks, hit and dodge tasks, and search and puzzle tasks.

[0069] Furthermore, each interactive task in the preset task library is matched with parameters from the preset virtual scenario library, thereby assigning a different virtual scenario to each interactive task. Specifically, the design specifications for each interactive task are as follows:

[0070] (1) Meditation and Relaxation Task: Explain the principles, purpose, and content of mindfulness intervention to the patient, which includes four stages. ① Body Scan: Under the guidance of voice prompts, the user perceives the sensations in different parts of the body. ② Mindful Breathing: The user perceives the sensation of airflow passing through the nasal cavity and changes in the chest and abdominal cavities during breathing. ③ Mindful Relaxation: The user perceives the sensations of muscle tension and relaxation. ④ Mindful Yoga: The user follows the yoga instructor in the scene to complete yoga poses such as upper body stretching, leg stretching, supine leg extension, and mountain pose.

[0071] (2) Note the game task: The scene is designed as a ship sailing on the sea. Users use VR controllers to control a lightsaber to hit the rock obstacles in front of them and avoid the seabirds around them, according to the rhythm of the music. Subjects can slow down the ship's speed by shouting louder, thus reducing the difficulty of the game.

[0072] (3) Rational Emotion Task: Using VR technology, common conflict scenarios are provided. By talking with virtual characters and choosing different beliefs about the same event, different situational outcomes are obtained, reconstructing the individual's irrational cognition.

[0073] (4) Emotional catharsis task: Using VR technology, users are provided with a safe and controllable space to release their stress and negative emotions by hitting, shouting, or diverting their attention with the help of tools. For example, some vases are written with negative words, guiding users to break such vases in the game, and providing users with a soothing scene after the catharsis is over.

[0074] (5) Fear desensitization task: Using virtual technology, the fear trigger is brought into the present. When the user has a fear response, a quiet and peaceful environment in the virtual environment is selected to guide the user to calm down and feel the peaceful and beautiful atmosphere. By continuously strengthening the connection between the stimulus and the relaxed state, the connection between the bad stimulus and the fear is finally cut off.

[0075] (6) Item Memory Task: Using VR technology to simulate real-life scenarios such as family rooms and convenience stores, the task is to memorize items on a list and find the target item in the scenario.

[0076] (7) Hit and Dodge Tasks: Simulate a fruit-cutting scenario where different fruits will randomly appear in front at a specific speed. The user holds the controller and swings their upper limbs to cut the fruit in half. Simulate a dog-running scenario where the user controls the dog's running direction with the controller to avoid various obstacles on the track.

[0077] (8) Search and puzzle task: Simulate real-world park jogging or walking routes, maze games, scenic area tasks, etc., requiring users to find the correct path according to the map and pick up the props marked on the map; Virtually present several fragments of a cube, allowing users to restore the cube based on complete background information.

[0078] Each dimension in step S1 above corresponds to a different interactive task in the preset task library, and the specific correspondence is as follows:

[0079] Type A depressive symptoms correspond to meditation and relaxation tasks and attention-based gaming tasks;

[0080] Type B anxiety symptoms correspond to meditation and relaxation tasks and rational emotive behavior tasks;

[0081] Type C stress symptoms correspond to meditation relaxation tasks and emotional catharsis tasks;

[0082] Type d fear symptoms correspond to meditation and relaxation tasks and systematic desensitization tasks;

[0083] E-class memory, F-class attention, and G-class visuospatial and executive functions correspond to object memory tasks, attention corresponds to hit and dodge tasks, and visuospatial and executive functions correspond to find and puzzle tasks.

[0084] Understandably, after obtaining multiple dimensions that the user needs to improve based on step S1, corresponding interactive tasks can be obtained based on the above correspondence, forming a combination of interactive tasks. For example, if the user experiences depressive symptoms and stress symptoms, and has weakened memory, the combination of interactive tasks would be: meditation relaxation task, attention game task, emotional catharsis task, and object memory task.

[0085] S3: Obtain personalized emotional and cognitive interaction solutions for perinatal women corresponding to the user.

[0086] Specifically, this includes steps S31 to S34:

[0087] S31: Obtain the combination of interactive tasks from step S2 above;

[0088] S32: Based on the severity marked in D1 of step S1, obtain the interaction order of all interaction tasks in the interaction task combination and the interaction duration of each interaction task.

[0089] S33: Determine the interaction cycle based on the number of dimensions to be improved and the interaction duration of each interaction task; the more dimensions there are and the longer the interaction duration of each interaction task, the longer the interaction cycle will be, and vice versa.

[0090] S34: By utilizing the combination of interactive tasks, the interaction order of all interactive tasks, the interaction duration of each interactive task, and the current interaction cycle, a personalized emotion and cognitive interaction scheme for the user is constructed.

[0091] S4: Based on personalized emotional and cognitive interaction solutions for perinatal women, obtain behavioral response data of users when engaging in emotional and cognitive interactions.

[0092] In this embodiment, the interaction period is set to a preset number of days (e.g., one week). When the user starts the personalized interaction program for perinatal women's emotions and cognition, the number of days of interaction increases by one every day until the number of days of interaction equals the interaction period, and the interaction program for perinatal women's emotions and cognition in this period ends.

[0093] During the interaction, the system interacts with the user through motion capture, visual feedback, eye tracking, gesture tracking, orientation tracking, voice interaction, and sensors. After the user completes the emotional and cognitive interaction of the perinatal women in this cycle, the system obtains the user's daily behavioral response data for subsequent result display.

[0094] S5: Based on user behavior response data, provide feedback to users on the results of the perinatal women's emotional and cognitive interactions during this period and end the perinatal women's emotional and cognitive interactions during this period.

[0095] Specifically, user behavior and response data are collected daily, and the daily interaction results are displayed. These results include the number of interactions and duration for each emotional interaction task, as well as the number of interactions, duration, and score for each cognitive interaction task. This allows users to observe their daily interactions and understand their daily state changes.

[0096] Furthermore, once a cycle of interaction is completed, based on the daily interaction results displayed within this cycle, the user's emotional and cognitive changes during this cycle are shown to provide comprehensive feedback to the user on the emotional and cognitive interaction results of women during this perinatal period.

[0097] S6: Repeat steps S1 to S5 until the user's emotional and cognitive assessment data reach the preset expected level.

[0098] Specifically, after a user completes a cycle of perinatal emotional and cognitive interactions, the user's emotions and cognition are reassessed based on the scale. The interaction task combination is then rematched based on the user's emotional and cognitive assessment data to conduct the next cycle of perinatal emotional and cognitive interactions, until the user's emotional and cognitive assessment data reaches the preset expected level.

[0099] Furthermore, in a preferred embodiment of the present invention, in order to increase the user's initiative and enthusiasm, a flower-growing game is used as the program and the story background. In step S1, when the user completes the emotion and cognition assessment, he / she will randomly receive virtual flowers. By completing the corresponding interactive tasks, he / she can obtain water droplets to help the flowers grow.
