Description

Technical Field

[0001] This invention relates to the field of crowd emotion propagation simulation in special scenarios, and in particular to a method and system for crowd emotion propagation simulation in special scenarios based on Unity3D. Background Technology

[0002] In real-world crowd movements, emotional contagion is a common phenomenon. Emotions are psychological activities arising from cognition and consciousness, influencing not only individual behavior but also the emotions of others, and consequently, their behavior. The identification and efficient analysis of group behavior patterns is at the forefront of information science research and represents a significant need for national social security and strategic development.

[0003] Major biosafety emergencies exert immense pressure and impact on human psychology and physiology. Such events are particularly prone to causing emotional fluctuations, inducing anxiety, depression, and other negative emotions. Furthermore, these negative emotions spread rapidly, potentially leading to loss of control over group behavior. On warships, soldiers frequently operate in high-pressure, highly stressful environments, spending extended periods in confined spaces performing complex tasks and facing various challenges and dangers. In this environment, the spread of emotions can be amplified, negatively impacting soldiers' physical and mental health, such as causing depression, anxiety, and stress. The spread of emotions can also lead to tension and disharmony among soldiers, affecting their cooperation and teamwork abilities. In severe cases, it can directly threaten national defense, economic, and social security.

[0004] However, existing research on the spread of emotions in crowds primarily relies on classic epidemiological models or emotion transmission models based on heat transfer mechanisms. While both models can reflect the patterns of emotion transmission within a group to some extent, they still have many shortcomings. Epidemiological-based emotion transmission models neglect the continuity and bidirectional nature of emotion transmission. Existing emotion transmission models based on heat transfer mechanisms, although considering the bidirectional and continuous nature of emotion transmission, do not account for the direct impact of an individual's current emotional state. Therefore, they are prone to distortion in simulation results and cannot accurately simulate reality. Furthermore, existing crowd emotion transmission simulations are usually only used for experimental comparisons in evacuation scenarios and cannot simulate the patterns of crowd emotion transmission in special scenarios such as warships.

[0077] Through extensive research and practice, the inventors of this application have discovered that existing studies on the transmission of emotions in populations primarily rely on classic epidemiological models or emotion transmission models based on heat transfer mechanisms. While both models can reflect the patterns of emotion transmission within a group to some extent, they still have many shortcomings. In epidemiological-based emotion transmission models, an individual's emotional state only influences the emotional state of others when that individual has a clear emotional expression; a lower emotional state does not affect the emotions of others. This type of model often only considers the contagious effect of negative emotions on individuals with normal emotions, neglecting the calming effect of normal emotions on individuals with negative emotions, and ignoring the continuity and bidirectional nature of emotion transmission. Existing models of emotion transmission based on heat transfer mechanisms, while considering the bidirectional and continuous nature of emotion transmission and viewing it as a continuous emotional exchange between two people, acknowledging that even minor emotions can spread, treat an individual's emotional receptiveness and expression abilities as fixed values ​​solely related to their personality traits. However, according to fundamental theories of emotion transmission, an individual's emotional receptiveness and expression abilities during the transmission process are not only determined by their personality traits but also directly influenced by their current emotional state. Failure to incorporate these factors into simulation systems when studying group emotion transmission leads to distorted simulation results and an inability to accurately reflect reality. Furthermore, existing simulations of crowd emotion transmission are typically limited to comparative experiments in evacuation scenarios and cannot simulate the patterns of crowd emotion transmission in specific environments such as warships.

[0078] Therefore, this invention proposes an improved crowd emotion transmission model based on heat transfer mechanism in special scenarios. According to the basic theory of emotion transmission, the ability of an individual to transmit emotions to others is dynamically correlated with the individual's current emotional state. It focuses on the differences in the ability performance of individuals under different emotional states. At the same time, for special scenarios such as warships where terrain is limited and personnel activity rules are highly restricted, a simulation method and system for crowd emotion transmission in special scenarios based on Unity3D is designed. The specific environment is spatially modeled, and the simulation of the emotion transmission mechanism of special personnel is carried out through algorithm deduction, which helps to realize the early detection of high-risk oversights.

[0079] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

A scaled-down map was then created using the Unity3D platform to serve as the simulation scene map. The positions of light sources and cameras were then set within the scene model for rendering and drawing.

When an event occurs, obtain the individual model's own position and the target point position to realize automatic pathfinding and obstacle avoidance as the individual moves towards the target.

[0095] In the specific implementation process, when instantiating the individual model, rigid bodies of different colors, Spheres, are used to represent individuals with different emotional states, such as green for individuals in a normal state, yellow for individuals in a worried state, orange for individuals in an anxious state, and red for individuals in a panic state.

When an individual is in a state of panic, their rationality and judgment drop sharply, and their emotional acceptance ability is significantly weakened.

[0115] S4.3: Calculate the channel strength value for emotion transmission between individuals. During emotion transmission, when the emotion sender S expresses emotion to the emotion receiver R, Let S be the channel strength value between the emotion sender S and the emotion receiver R. This value is related to the distance between the sender and receiver. This represents the physical distance between the emotion sender S and the emotion receiver R. The channel strength of emotion propagation is represented by the radius of the perceptual domain in which emotion can propagate. Defined as:

[0116]

[0117] S4.4: If within the physical radius of individual R If there are multiple individuals capable of expressing emotions, then these individuals can transmit emotions to individual R. These individuals, along with individual R, are denoted as group G. The overall intensity of emotion transmission received by individual R from other members within the group is calculated. :

[0144] In step S5.4, the motion control of each individual is implemented based on the AI ​​engine and physics engine built into Unity3D. The FixedUpdate() function in the C# script bound to each individual is used for updating. If the current simulation system time t is greater than the start time of the next time item in the current motion plan, the SetDestination() function in the NavMeshAgent component is used to set the target point agent.destination of the individual's current motion to a random position in the destination space of the next time item, guiding the individual to move towards the target point.

[0145] Example 2

[0146] Based on the same inventive concept, this invention discloses a simulation system for the transmission of crowd emotions in a special scene based on Unity3D, comprising:

[0147] 3D special scene model, used to build 3D special scene models based on real-world scene data and the Unity3D platform;

[0152] In one implementation, the simulation configuration scheme design module specifically includes:

[0153] The motion plan management module is used to create and manage the motion plans of crowds during the simulation. Because the movement of people in strictly closed management places such as military bases often exhibits strong regularity, the simulation system provided in this paper supports the subdivision of crowd motion plans down to the hour. It can create corresponding and reasonable motion plans for individuals in the crowd based on their different identities and responsibilities.

[0154] The Add Personnel module is used to create groups of people with specified exercise plans, birthplaces, and initial emotional information.

[0160] The simulation visualization module presents the evolutionary trends of crowd movement and emotional transmission during the simulation process in an intuitive way.

[0161] The simulation statistics module displays the current emotional state of the crowd using specific numbers and statistical charts, making it easier to understand the group's emotional state.

[0162] This invention provides a simulation system for the propagation of crowd emotions in a special scene based on Unity3D, such as... Figure 2 The image shows a simulation system based on a Windows operating environment. The UI and scene transitions are primarily implemented using Panel components. The `SetActive()` function in Unity3D, which controls the activation and deactivation of game objects, is used to control the display and hiding of each Panel, thus avoiding the use of Scene transitions. Specifically, after all operations on the current Panel are completed, it is deactivated and its interface is hidden, while the associated next Panel is displayed to achieve a similar effect. This method not only reduces the parameters for scene loading and transitions but also significantly improves the system's smoothness.

[0163] Figure 3 This diagram shows the main interface of a Unity3D-based simulation system for simulating the spread of emotions in a specific scene. To display images related to different deck levels on the main interface, the system uses a secondary camera to monitor the activity space within the scene and projects these images as textures onto the Unity graphical user interface (UGUI) for real-time display of the simulation process. Furthermore, considering the three-deck structure, the system provides corresponding scene switching buttons. Users can freely click the corresponding button components to switch camera positions and view different deck levels, facilitating observation of the emotional state of people on different deck levels and a better understanding of the evolution of the simulation process.

[0164] The functional modules employ modular programming. The main system functional modules include a motion plan management module, a personnel addition module, an emotion propagation macro-setting module, a personnel management module, a data management module, a simulation control module, a simulation visualization module, and a simulation statistics module. The functions of each module are described below:

[0165] The motion plan management module is used to create and manage the motion plans of crowds during the simulation process. Since the movement of people in strictly closed management places such as military bases often exhibits strong regularity, the simulation system provided by this invention supports the subdivision of crowd motion plans down to the hour. It can create corresponding and reasonable motion plans for individuals in the crowd based on their different identities and responsibilities.

[0166] The Add Personnel module is used to create groups of people with specified exercise plans, birthplaces, and initial emotional information.

[0167] The macro-level settings module for emotion propagation is used to macroscopically regulate the perceptual range at which emotion propagation can occur, control the macro-level channel strength of emotion propagation to regulate the speed of emotion propagation within a crowd, and control the time interval between each occurrence of emotion propagation. This module provides users with the possibility of customizing macro-level factors related to emotion propagation. Users can increase the perceptual range radius to expand the impact of emotion propagation and accelerate its spread within a crowd by increasing the macro-level channel strength value. This functionality is primarily implemented using the InputField component in Unity3D, which provides input fields for users to enter their own content.

[0168] The personnel management module is used to view the changes in the emotional values ​​of a specified individual during the simulation. It also supports the modification of emotional transmission parameters such as emotional value, emotional expression ability, and emotional acceptance ability, as well as the selection of movement schemes for a specified individual during the simulation.

[0169] The data management module is used to import and export personnel and motion plans in JSON file format during the simulation process, supporting the saving and reuse of simulation plans. The system uses JSON files for data management, implemented using the LitJson library within the Unity system. LitJson is a C#.NET library used for handling JSON string conversions. LitJson includes the JsonMapper class, which provides two methods, JsonMapper.ToObject() and JsonMapper.ToJson(), to achieve JSON-to-object and object-to-JSON conversions. The system primarily uses these two methods to serialize and deserialize the crowd and motion plans.

[0170] The simulation control module controls the start, pause, and resume of the simulation, and supports real-time adjustment of the simulation speed. Starting the simulation is controlled by modifying a boolean variable. Initially, the boolean value is false; when the Button component is clicked to start the simulation, the boolean variable is changed to true, and the simulation begins. Resuming and pausing the simulation are controlled by modifying the value of `Time.timeScale`. `Time.timeScale` affects the scaling ratio of Unity's game time; its range is a floating-point number between 0 and 100. Modifying `timeScale` affects the execution speed of `FixedUpdate`. When `Time.timeScale` = 0, the simulation pauses; when `Time.timeScale` = 1, the simulation resumes. When the Slider component is used to zoom in or out on `Time.timeScale`, the simulation speed increases or decreases accordingly.

[0171] The simulation visualization module presents the evolutionary trends of crowd movement and emotional transmission during the simulation process in an intuitive way.

[0172] The simulation statistics module displays the current emotional state of the crowd using concrete numbers and statistical charts, facilitating a better understanding of the group's emotional state. The data statistics module primarily includes real-time updates of the number of people in different situations, and the use of the XCharts plugin to display the changes in the average emotional value of the current group as a curve chart, making the data on the spread and evolution of group emotions clearer and more intuitive.
