[0030] The present invention relates to a method for analyzing the characteristics of an AI-based game character. FIG. 1 is a flowchart for analyzing the characteristics of an AI-based game character related to one embodiment of the present invention, and will be described below with reference to FIG. 1.

[0031] The game in one embodiment of the present invention may be a strategy game and includes game genres such as action games, RPGs, etc. It also includes real-time strategy (RTS), real-time tactics (RTT), 4X, turn-based strategy, and turn-based tactics games. In other words, it is not particularly limited as long as it is a game in which a character within the game can be analyzed. More specifically, it is sufficient if the character within the game makes judgments, decisions, and executes them on their own in situations such as negotiation, combat, corporate management, poker games, planning, discussion, art, trading, and collaboration. Furthermore, it includes turn-based, semi-turn-based, or real-time games, and may be a role-playing game, action game, adventure game, fighting game, sports game, racing game, strategy game, shooting game, music game, card game, bishoujo game, adult game, casual game, multiplayer online battle arena, etc.

[0032] A method for analyzing the characteristics of an AI-based game character according to an embodiment of the present invention comprises the steps of: first, collecting game data including behavior patterns, conversation patterns, and movement patterns of said character in various situations within the game for the purpose of analyzing characteristics including ability scores and tendencies of said character active within the game (S110); analyzing the characteristics of said character based on the collected game data (S120); and updating the analyzed characteristics as the characteristics of said character (S130). At this time, the characteristics of said character are expressed through various functions within the game, such as analysis reports and interactions with NPCs (Non-Player Characters).

[0033] The characteristics in this case may include ability scores, values, or dispositions, and thus a definition of values ​​is required. In one embodiment of the present invention, multiple pairs of values ​​are defined with opposing values ​​as the two ends, and a method can be applied to adjust the search results obtained through analysis into the spectrum categories of the corresponding pairs of values. For example, types of value pairs may include trust-opportunity, dominance-compromise, gambling-stability, and greed-sharing. The subjects to which values ​​apply may include social contribution, talent development, brand strengthening, and technological growth. Values ​​tend to maintain consistency only within the scope of application; for example, a soldier may be a devoted father at home but a ruthless warrior on the battlefield.

[0034] Additionally, the above steps S110 to S130 may be repeated regularly or irregularly, and when the characteristics of the character are analyzed repeatedly, continuous feedback is provided to the character (S140).

[0035] In other words, in one embodiment of the present invention, game data of a character in a game is analyzed to adjust character characteristics and the game environment accordingly, or an AI (artificial intelligence) within the game continuously analyzes the character's gameplay style and behavioral patterns. Through this, the game experience can be personalized, and the game can be optimized to match the character and, furthermore, the player's tendencies.

[0036] Meanwhile, in one embodiment of the present invention, it can be said that the in-game character's disposition is similar to that of the actual player. Based on psychological grounds, it can be said that "choices made in the game reflect the player's personality." According to the theory of "Behavioral Consistency" in psychology, people tend to make their characters act in accordance with their own dispositions. In particular, in environments with a high degree of freedom, such as games, a player's inner disposition naturally emerges. As evidenced by statements such as "people who show aggressive tendencies in games are likely to show a challenging personality in reality" or "cooperative players tend to value social relationships in reality," people with cautious personalities in real life are more likely to play defensively rather than directly attacking enemies in the game, while people with spontaneous and adventurous personalities in real life are more likely to enjoy exploration and make risky choices in the game.

[0038] In one embodiment of the present invention, first, an AI (Artificial Intelligence) collects game data of a character in real time (S110). The game data includes behavioral patterns, conversation patterns, and movement patterns, as well as combat styles, negotiation styles, quest selections, interactions with NPCs, etc., and includes all game data within the game necessary to analyze the characteristics of the character. The game data does not refer only to specific actions of the character, but also includes actions of commission or omission resulting from the player's manipulation or non-manipulation within the game, and the character's reaction time is also included in the game data.

[0039] For example, it identifies whether a character is aggressive, exploratory, or diplomatic during combat. This game data is used to analyze the character or player's tendencies. Through this analysis, the AI ​​can distinguish whether a player is aggressive or cautious. Furthermore, it can provide more challenging battles for aggressive players and offer strategic choices to cautious players.

[0040] Such game data can serve as a basis for analyzing a character's abilities or tendencies, and the aforementioned basis may include selection commands that include the timing, conditions, and extent of a command that the user can freely choose within the game, condition commands that include the player's choices, conditions, and extent regarding various events occurring within the game, and orientation points that are elements the user focuses on for growth within the game.

[0041] In this regard, the following explanation will assume an economic simulation game.

[0042] Setting the salary of potential hires lower than that of competitors can serve as a 'choice command' for the character; in this case, the 'timing' is the early stages of the game, the 'conditions' involve significant financial difficulties, and the 'degree' involves a relatively high proportion of the marketing and R&D budget. Although the salary was set lower than competitors in this instance, this is due to the financial hardship; nevertheless, the high proportion allocated to marketing and R&D can be analyzed as the character's effort to maintain employee stability.

[0043] Furthermore, if a character accepting a proposal for a new business item can serve as a 'conditional command,' where the 'timing' is the mid-stage of the game, the 'condition' is a situation where the current item is struggling to sell, and the 'degree' involves a minimal investment that does not affect the company's flagship item, it can be analyzed as a tendency to avoid gambling-like risks.

[0044] In addition, the character at this time may set a 'goal' that involves building a solid foundation from the basics and experiencing various elements of the game, with a high probability of growing slowly but steadily; in such cases, it can be analyzed that there is a tendency to seek stability based on trust.

[0046] In addition, the above character can converse in natural language with other characters or NPCs in various situations given within the game, and through said conversation, grounding elements for analyzing the characteristics of said character can be extracted.

[0047] Afterwards, the characteristics of the above character are analyzed (S120) based on the collected game data.

[0048] The collected game data is passed to an AI analysis module to analyze the player's tendencies. For example, an aggressive character may exhibit a combat-oriented tendency, while an exploratory character may display behavioral patterns centered on exploration. Through this, the AI ​​can classify the character or player's tendencies into various categories, such as aggressive, defensive, diplomatic, and exploratory. Furthermore, if a player controls a character aggressively, the AI ​​learns this to evolve the character into one with reinforced aggressive tendencies, while if the player frequently attempts to converse or cooperate with NPCs, the character grows to possess diplomatic and cooperative traits.

[0049] At this time, at least one of the steps of collecting game data (S110), analyzing character characteristics (S120), updating characteristics (S130), and providing continuous feedback to the character (S140) may be performed by artificial intelligence, and AI technology may be applied in all of the above steps.

[0050] In the step of providing continuous feedback, the appearance of the character may be changed, or when the character interacts with an NPC or other character, the behavior or reaction of the NPC or other character may change according to the character's characteristics, or the psychological state of the player may be predicted based on the analyzed game data of the character, or items, skills, quests, or strategies suitable for the character may be recommended within the game based on the character's game data. When the appearance of the character is changed, it means that the character's facial impression, voice, clothing, size, shape, color, etc., change before and after the update.

[0051] Below, we will explain this.

[0052] First, machine learning technology can be utilized to analyze behavior patterns. Machine learning technology identifies patterns by analyzing character game data using machine learning (ML) algorithms. For example, it can determine whether a character is aggressive or defensive by analyzing attack / defense / evasion ratios during combat, decide whether they are cooperative or selfish by analyzing dialogue choices with NPCs, or classify tendencies by analyzing play styles (fast progression vs. exploration-focused). In particular, K-Means Clustering Algorithm technology can be used to cluster various types of players and classify them into groups with similar characteristics, or Random Forest / XGBoost technology can be used to classify character tendencies based on game data.

[0053] Furthermore, Natural Language Processing (NLP) can be used to analyze NPC dialogue and text. Specifically, the content of conversations shared between a character and other characters or NPCs in the same game space can be analyzed to evaluate tendencies, or GPT-based models can be utilized to determine whether the conversational style is aggressive, persuasive, or friendly. In particular, BERT (Bidirectional Encoder Representations from Transformers) technology can be used to analyze dialogue text to identify emotions and intentions, and GPT (Generative pre-trained transformer) technology can be used to generate NPC responses that reflect the player's conversational style.

[0054] In addition, for image and behavior recognition It can also be utilized to identify specific patterns by analyzing character movements using Convolutional Neural Networks (CNN) technology or pose estimation technology.

[0055] Furthermore, in one embodiment of the present invention, AI technology for updating and evolving character traits may be used. For example, the AI ​​may learn the actions that a character repeatedly chooses based on Reinforcement Learning (RL) to gradually strengthen character traits, or the AI ​​may evaluate the player's choices using a reward / penalty system to continuously adjust the character's disposition. For example, for a challenging character, the AI ​​may adjust the difficulty of enemies to place stronger opponents, and for a peaceful character, the AI ​​may provide more options to avoid combat. In particular, the AI ​​may learn to perform optimal actions by providing rewards based on the character's actions using Deep Q-Networks (DQN) technology, or learn to respond appropriately by analyzing player actions using Proximal Policy Optimization (PPO) technology.

[0056] Furthermore, in one embodiment of the present invention, NPCs and environments can be modified using AI. For example, NPC behavior can be generated based on a Generative Adversarial Network (GAN). By utilizing a GAN, NPCs can be designed to exhibit more natural responses, or they can provide customized responses learned by the AI ​​in real-time, rather than pre-defined behavioral patterns. More specifically, if a character frequently exhibits a cooperative style, NPCs can be made to display a more cooperative attitude, while conversely, NPCs can be made to be wary of or respond more aggressively to a hostile character. Additionally, by utilizing Dynamic Difficulty Adjustment (DDA), the AI ​​can analyze the player's level and characteristics in real-time to automatically adjust the game's difficulty. More specifically, enemy attack patterns, item drop rates, and quest difficulty can be automatically adjusted, and the AI ​​can intervene to ensure the player does not find the game too easy or too difficult. In particular, StyleGAN technology can be used to generate new NPC faces, expressions, and clothing.

[0057] Furthermore, in one embodiment of the present invention, characters can be made to continuously develop or evolve based on AI. For example, a character's personality can be established through persona learning. By analyzing the player's choices and actions, the AI ​​can determine an individual personality for each character or learn to ensure that the character maintains a consistent personality in specific situations. More specifically, NPCs may not trust a character who tells many lies, while NPCs may respect a character who helps the weak and provide them with additional quests.

[0058] In addition, by utilizing an AI co-pilot based on a Large Language Model (LLM), personalized recommendations tailored to the character can be made, for example, by suggesting, "Looking at your personality, I think this quest would suit you!" or "Looking at your last decision, there were some regrets, so would you like to try this choice this time?"

[0059] As such, in one embodiment of the present invention, by applying various AI technologies to a game, a game environment can be created in which a character continuously grows and changes according to the player's tendencies. That is, by analyzing behavior through AI to identify and reinforce character characteristics, and by adjusting NPCs, other characters, and the environment to suit the changed character, a more immersive game experience can be provided.

[0060] In addition, in one embodiment of the present invention, the character's characteristics are updated (S130) after analyzing the character's continuous behavioral patterns. For example, a character who prefers strategic thinking may gradually change to a defensive tendency over time, and these characteristics are updated in the character. Subsequently, the character's past game data can be analyzed to predict future decision-making patterns, and the AI ​​can learn the player's game style and be set to recommend or automatically perform predictable actions when similar situations occur. For example, if there is a pattern of running away during combat or if the character faces a desperate situation during negotiation, the AI ​​may automatically suggest evasion actions upon detecting danger. Furthermore, for a character with a strong aggressive tendency, the AI ​​may automatically upgrade the attack power by "5%," and for a character who explores a lot, the AI ​​may add "increased movement speed" or "hidden item detection ability."

[0061] In addition, in one embodiment of the present invention, the NPC's reaction may be set to change according to the character's characteristics. Interaction with the NPC can be modified not merely by changing dialogue, but by changing the NPC's behavior itself. For example, if the player's character exhibits a deceptive play style, the NPC may be made to show a reaction of greater wariness or distrust; conversely, if the character repeatedly performs benevolent actions, the NPC may offer assistance first or provide special quests.

[0062] As such, in one embodiment of the present invention, the in-game environment can change according to the characteristics of the character, and when the character has a specific tendency, the in-game environment changes to reflect this.

[0063] In addition, continuous feedback is provided to the character, other characters, or NPCs (S140). In this step, the appearance of the character may be changed, or the psychological state of the player may be predicted based on the analyzed game data of the character. Additionally, items, skills, quests, or strategies suitable for the character may be recommended within the game based on the game data of the character. That is, the AI ​​may detect changes in the character's characteristics in advance and adjust the difficulty or quests within the game. Furthermore, the AI ​​may gradually change the game environment to match changes in the player's tendencies, allowing the player to continue experiencing new challenges. Additionally, the AI ​​may analyze the player's choices and behavioral patterns to adjust the reward system to suit the tendencies, and may adjust the game considering fatigue or immersion. At this time, the player's facial expressions may be analyzed using a heart rate sensor linked to a smartwatch or a webcam.

[0065] Furthermore, the characteristics of the aforementioned character are expressed through interactions with NPCs (Non-Player Characters) within the game. The AI ​​analyzes the character's tendencies in real-time through these interactions and adjusts the character's traits accordingly. For example, if a character frequently performs a specific action, the AI ​​can more accurately identify the character's or player's tendencies and provide appropriate stats or items. Additionally, the AI ​​can consider psychological factors such as fatigue and immersion to further personalize the game and develop it in an efficient direction.

[0067] Meanwhile, in one embodiment of the present invention, an AI-based character characteristic analysis and evolution system (100) is provided, which will be described below with reference to FIG. 2.

[0068] FIG. 2 is a block diagram of an AI-based character trait analysis and evolution system related to the present invention.
