Title: Method for analyzing personality or aptitude based on metaverse and artificial intelligence

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to Korean Patent Application No. KR10-2022-0112115 filed on Sep. 5, 2022, Korean Patent Application No. KR10-2021-0187245 filed on Dec. 24, 2021, and Korean Patent Application No. KR10-2021-0156521 filed on Nov. 15, 2021 and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which are incorporated by reference in their entirety for all purposes. 
     BACKGROUND 
     The present disclosure relates to a method for analyzing personality or aptitude, and more particularly, to a method for analyzing personality or aptitude based on metaverse and artificial intelligence. 
     The metaverse is a compound word of “meta”, meaning virtual and transcendence, and “universe”, meaning the world and cosmos, and refers to a virtual world where real life and legally recognized activities such as work, finance, and learning are connected in three dimensions (3D). That is, the metaverse is a concept that has evolved one step further than virtual reality (VR), and has the feature of being able to engage in social and cultural activities similar to those in real reality, not just enjoying games or virtual reality using avatars. 
     Acceleration Studies Foundation (ASF), a non-profit technology research group, classifies metaverse into four types: augmented reality, life logging, mirror worlds, and virtual worlds. 
     Augmented reality refers to an environment that interacts through virtual superimposed objects expressed in two dimensions (2D) or 3D in real space. Augmented reality has the characteristics of reducing people&#39;s rejection of the virtual world and increasing the sense of immersion. An example of augmented reality is a scene where a digitally constructed building of the past is displayed on a terminal of a user in a superimposed manner when the user takes a picture of the traces that currently remains only as ruins with a terminal camera. 
     Lifelogging is the art of capturing, storing, and depicting everyday experiences and information about objects and people. A user can capture every moment in his or her daily life as text, video, sound, or the like, store and organize the content on the server, organize, and share the organized content with other users. An example of a daily life record is to store and share information such as distance covered, calories burned, and music selection by linking sportswear with sensors to an MP3 player capable of connecting to a network. 
     The mirror world refers to a virtual world that reflects the real world as realistically as possible and as it is, but is expanded informationally. A typical example is Google Earth. Google Earth collects all satellite photographs from all over the world and updates the photographs at regular intervals, reflecting the ever-changing real world as it is. As technology continues to develop, the mirror world that reflects reality will become closer to the real world, which will become a major immersive element of virtual reality in the future. Users of the mirror world obtain information about the real world by viewing the virtual world. 
     The virtual world is one built by digital data for an alternative world similar to reality or completely different. In the virtual world, users perform activities similar to economic and social activities in the real world through avatars. The virtual world is the most familiar form of metaverse, and a concept that collectively refers to a community implemented in a 3D computer graphic environment from online role-playing games to living virtual worlds such as SANDBOX, ZEPETO, and Roblox. 
     Examples of the related art include Korean Patent Laid-Open Publication No. 10-2019-0108523 (Sep. 24, 2019).

     Hereinafter, with reference to the accompanying drawings, preferred exemplary embodiments of the present disclosure will be described clearly and in detail so that those of ordinary skill in the art to which the present disclosure pertains can easily practice the present disclosure. 
       FIG.  1    is a flowchart of a method for analyzing personality or aptitude based on a metaverse and artificial intelligence, which is performed in a personality or aptitude analysis system in accordance with an exemplary embodiment of the present disclosure. 
     Referring to  FIG.  1   , in the personality or aptitude analysis system, at least one of voice information and visual information is acquired in step S 110 . The voice information may be acquired by voice recognition technology based on ontology (natural language machine learning), and the visual information may include information that may be determined by sight without limitation, such as text information such as a writing style of a user or the model name displayed on an object the user is holding, facial information such as the appearance and facial expression of the user and appearance changes between normal and difficult activities, user gesture information, object information such as clothes the user is wearing, and the like. In the acquiring, in addition to voice information and visual information, various information including biometric information such as brain waves and DNA that is possible to be acquired by using an appropriate sensor may be further used. Conversations exchanged, recorded information, and patterns may also be used as analysis and learning information. 
     In the personality or aptitude analysis system, in step S 130 , as a simple sorting-out step for the personality or aptitude of the user, the personality or aptitude of the user is analyzed using at least one of the voice information, the visual information, and the biometric information. Specifically, at least one of the voice information, visual information, and biometric information for the user may be analyzed, and the personality or aptitude of the user may be primarily analyzed using the analyzed data. The biometric information may be analyzed by acquiring brain waves responding to at least one stimulus among sight, hearing, taste, touch, and smell for a specific period of time and performing the brain wave analysis. In addition, in the analysis of the biometric information, unique DNA information may be analyzed by comparing the biometric information with a data information map in which characteristics of each DNA element and structure are analyzed. For the biometric information, it is possible to predict the personality or aptitude of the user by comparing and analyzing results predicted through the accumulated biometric analysis. 
     In the personality or aptitude analysis system, the personality or aptitude of the user primarily analyzed in step S 130 , and the personality or aptitude of the user may be recommended based on the primary personality or aptitude data. For example, in the case of the generating of the primary personality or aptitude data, the occupation or personality or aptitude of the user may be analyzed in the physiognomic aspect through artificial intelligence learning. That is, by using the artificial intelligence trained on the face or voice of the user, from information on the voice or face of the user, the occupation of the user may be analyzed as a president or an athlete, and the primary personality or aptitude data for the personality or aptitude may be analyzed. The primary personality or aptitude data may be updated depending on future actions or words of an avatar of the user to generate secondary personality or aptitude data. 
     In the personality or aptitude analysis system, in step S 150 , user data including an analysis result of the personality or aptitude of the user n the simple sorting-out step is generated. The user data may include, for example, a user&#39;s ID, password, and data for analysis result of the personality or aptitude. The user data may include data obtained by analyzing the voice or a face image of the user, rather than voice data and face image data of the user itself. 
     Here, the user data is the user-specific data for the user temporarily acquired in the step prior to generating the secondary personality or aptitude data obtained by analysis based on the actions or words of the avatar. Here, the user data may be updated on a timeline. For example, in the simple sorting-out step for the personality or aptitude of the user, data analyzed in the physiognomic aspect such as the voice or face of the user may be updated while the personality or aptitude data is continuously being updated on a timeline. 
     In the personality or aptitude analysis system, in step S 170 , the avatar of the user is created using user data. The appearance or attire of the avatar may be determined according to the user data, and the user may live in the metaverse through the created avatar. 
     In the personality or aptitude analysis system, in step S 190 , the personality or aptitude of the user is analyzed in real time using the avatar, and artificial intelligence is trained. That is, the personality or aptitude of the user analyzed by artificial intelligence in step S 130  is not fixed. Initial data may be generated by simply sorting out the personality or aptitude of the user based on minimal voice information and/or visual information, and then, the personality or aptitude data for the user may be updated in real time or periodically by reflecting the actions or words of the avatar of the user in the metaverse. 
     As an example of reflecting the action of the avatar, the personality or aptitude data for the user may be updated depending on the action of the user, for example, whether the avatar runs or walks to a specific place. As another example, the personality or aptitude data for the user may be updated depending on, when the avatar moves to a specific place, whether the avatar moves to the specific place through a straight path or moves to the specific place through a detour path. 
     As an example of reflecting the words of the avatar, a word (subject, object, adverb, postposition, verb) that is used periodically or repeatedly in the words, conversation, or writing used by the avatar may be extracted through a redundancy check, and then interests and tendencies of the user using the avatar may be analyzed. 
     From the perspective of multimodal behavior patterns, the interests and tendencies of users using the avatar may be analyzed in consideration of words, conversations, or writing used by the avatar and the action (movement of the hands, the head, and the gaze) of the avatar together. For example, when the hand or head of the avatar is shaken or moved more actively in a specific word used by the avatar, interests and tendencies of the user using the avatar may be analyzed in consideration of whether the gaze of the avatar moves to a specific position or specific target within the virtual space, whether the gaze stops, the duration of a specific action, and so on. 
     Meanwhile, since the personality or aptitude data is updated using actions or words of the avatar rather than actions or words of the user, when the user wants to know his or her real personality or aptitude, the user may act or speak in the same way as he or she actually acts or speaks within the metaverse. On the other hand, in order to create an avatar having the personality or aptitude desired by the user, the user may act or speak in the metaverse differently from what he or she normally acts or speaks, and by reflecting the actions or words, the user may update the personality or aptitude as the user desires. 
     A communication service may be provided through a method such as matching with other users with a personality or aptitude similar to that of the user in the metaverse through analyzed user data or the avatar of the user, or matching with other users with a personality or aptitude opposite to that of the user. 
     In addition, a personality or aptitude test may be conducted as part of a hiring process of a company through the analyzed user data or the avatar of the user. For example, after setting up a work environment in a company and configuring the metaverse according to the setting, it is possible to check whether the avatar of the user is able to perform work while adapting well to the work environment set by the company. For example, when the work environment of the company where the user&#39;s avatar works is changed from a large space to a narrow space (e.g., a crowded space or a space with no light), a check whether or not the work progress of the user is reduced may be made. Alternatively, when the department of the avatar of the user with a role of developer in a company is changed to a sales department instead of a development department, a job adaptation degree of the user may be checked. 
     In addition, for a new recruit, for example, verification of the effectiveness of recruitment may be done by simulating the behavior of an artificially intelligent avatar reflecting the personality or aptitude of the new recruit in a virtual work environment. 
     In addition, for a new recruit, for example, verification of the effectiveness of recruitment may be done by evaluating the performance of the new recruit in terms of personnel evaluation when the avatar of the new recruit performs tasks in the metaverse for each department in a company. 
     In addition, for example, verification of the effectiveness of a new project to see what kind of synergistic effect it has may be done by putting avatars of existing staffs in the company and a new recruit into a virtual team to carry out the project in the metaverse space. 
     Compared to the case of taking a personality or aptitude test or the hiring process in reality, the user does not have to go to the test directly, which makes it possible to conduct an efficient personality or aptitude test or hiring process, which, in turn, can contribute to ESG (which stands for Environmental, Social and Governance) management from the company&#39;s point of view. 
     The user data analyzed when the avatar has been created is reflected, but whether or not to disclose the user data itself to others may be determined by a choice of the user. 
     The method for analyzing personality or aptitude in accordance with an exemplary embodiment of the present disclosure may be used not only to analyze the personality or aptitude of a user (that is, person) but also to analyze the aptitude of animals or things. 
     The aforementioned steps S 130 , S 150 , S 170 , and S 190  may be performed by an artificial intelligence engine of the personality or aptitude analysis system, and detailed operations will be described later with reference to  FIGS.  2  to  6   . 
       FIG.  2    schematically shows an overall process for creating an avatar in accordance with an exemplary embodiment of the present disclosure. 
     The method for analyzing personality or aptitude in accordance with an exemplary embodiment of the present disclosure may be serviced to a user as a metaverse personality or aptitude solution. The metaverse personality or aptitude solution may provide a personality or aptitude analysis service on the on-line basis when the user accesses it in real time, and may also provide the personality or aptitude analysis service off-line based on previously stored data when online access is not possible. Offline data may be synchronized with online data later on to reflect a result of offline analysis in online data. 
     The metaverse may be a virtual world copied from the real world, or may be a digital twin that works just like the real world. The metaverse may also be a world created by imagination or for a special purpose rather than reflecting reality as it is. 
     The user may access the metaverse space in various ways, such as accessing the metaverse space through VR equipment such as a head mounted display (HMD) or accessing the metaverse space through an application such as a smartphone or PC or a browser. 
     As shown in  FIG.  2   , when the user accesses the metaverse space and logs in, a registration process  203  for creating an avatar is performed. The registration process  203  may include a basic mode  210  and an expert mode  291 , and in the basic mode  210 , the avatar is created by simply sorting out the personality or aptitude using voice information  205  and/or face information  207 , and in the expert mode  291 , the personality or aptitude is analyzed more precisely by various tests such as the Strong&#39;s test, the MLST learning strategy test, the MBTI, the Enneagram personality or aptitude type test, and biometric information analysis (brain waves, DNA) as detailed tests. The expert mode is optional, and whether to perform may be determined according to a user&#39;s selection. 
     The personality or aptitude analysis may be performed by an artificial intelligence engine  200 . 
     In the basic mode  210 , voice information  205  and/or face information  207  is analyzed ( 211 ,  213 ), and personality or aptitude is analyzed by an artificial intelligence process ( 231 ,  233 ,  235 ), and as a result thereof, the personality or aptitude of the user is recommended ( 250 ), and an avatar is recommended ( 270 ). A detailed description will be given later. 
     In the expert mode  291 , personality or aptitude is analyzed by an expert personality process ( 293 ), or personality or aptitude is analyzed through an actual personality or aptitude test ( 295 ), and personality or aptitude is recommended according to the result ( 297 ), and an avatar is recommended ( 270 ). A detailed description will be given later. 
     That is, the artificial intelligence engine  200  recommends an avatar after analyzing the personality or aptitude of the user by using the voice information  205  and/or the face information  207 . The user may use the avatar recommended by the artificial intelligence engine  200  as it is ( 270 ), or customize the avatar. 
     When the avatar is created, the user enters the metaverse world and lives in the metaverse as his or her avatar. 
       FIG.  3    shows a process of analyzing voice information in accordance with an exemplary embodiment of the present disclosure. 
     Referring to  FIG.  3   , first, noise canceling and normalization is performed from the voice information  205  ( 211 - 1 ). That is, other sounds other than the voice of the user are removed from the acquired voice information  205  and the voice section is corrected to the maximum level. 
     Next, based on the voice information  205 , voice data  211 - 3  that is markable on a timeline are generated. The voice data is input data for personality or aptitude prediction, and may provide data that is markable on the timeline based on the length of the entire voice, and may be a part of a specific region of the voice information  205  or the entire region of the voice information  205 . The voice data  211 - 3  that is markable on the timeline may be used, for example, to distinguish between a section in which the user speaks quickly, a section in which the user speaks slowly, or a section in which words are emphasized through speech pattern recognition. The voice data  211 - 3  that is markable on the timeline may be automatically analyzed and marked as to which voice pattern it corresponds to at which point in time, not manually. When a fast speech is turned into a slow speech, the section may be determined as the section in which words are emphasized. Further, even when a fast speech is turned into a slow speech, the section may not be a section in which words are emphasized, and thus, a determination may be made as to whether or not the section is the section in which the user emphasizes his or her words in consideration of whether the intonation or tone of the user rises, or the gaze of the user together. 
     From the perspective of multimodality, in a specific section on the timeline, not only the words of the user but also behavioral data such as the user&#39;s hand motion or the position of the gaze may be marked together on the timeline. 
     Next, based on the voice information  205 , a voice style  211 - 5  including at least one of a voice tempo, a voice idle time, a tone, and a volume is generated. The voice style may be input data for predicting personality or aptitude or input data for predicting personality or aptitude in the form of marking on the timeline. 
       FIG.  4    shows a process of analyzing personality or aptitude using voice information in accordance with an exemplary embodiment of the present disclosure. 
     Referring to  FIG.  4   , the prediction ( 231 - 3 ) of personality or aptitude may be performed based on at least one of the voice data  211 - 3  and the voice style  211 - 5 , and the personality or aptitude may be predicted ( 231 - 3 ) through the machine learning (or deep learning) engine  231 - 5  and training is performed in real time. Voice personality or aptitude datasets  231 - 7  include at least one of data in which the personality or aptitude is classified according to the voice data  211 - 3  and data in which the personality or aptitude is classified according to the voice style. 
     When the personality or aptitude of the user is predicted ( 231 - 3 ) based on the voice data  211 - 3 , the personality or aptitude of the user may be predicted ( 231 - 3 ) by a first engine trained with training voice data classified for each personality or aptitude type, by using the voice data  211 - 3  as an input. For example, the similarity may be measured for each personality or aptitude type and a personality or aptitude with a high similarity may be predicted as a personality or aptitude result to be recommended to the user. The personality or aptitude of the user that has been predicted based on the voice data  211 - 3  is recommended to the user ( 250 ), and an avatar corresponding to the predicted personality or aptitude of the user is recommended ( 270 ). 
     When the personality or aptitude of the user is predicted ( 231 - 3 ) based on the voice style  211 - 5 , the personality or aptitude of the user may be predicted ( 231 - 3 ) by a second engine trained with a training voice style  211 - 5  classified for each personality or aptitude type, by using, as an input, an average value of the voice style  211 - 5  for a specific part that is easy to read. For example, the similarity may be measured for each personality or aptitude type and a personality or aptitude with a high similarity may be predicted as a personality or aptitude result to be recommended to the user. The personality or aptitude of the user that has been predicted based on the voice style  211 - 5  is recommended to the user ( 250 ), and an avatar corresponding to the predicted personality or aptitude of the user is recommended ( 270 ). 
     As another method, when the personality or aptitude of the user is predicted ( 231 - 3 ) based on the voice style  211 - 5 , the personality or aptitude of the user may be predicted ( 231 - 3 ) by a third engine trained with marking specific data or continuous pattern data in a marking section, by using, as an input, the voice style  211 - 5  marked in regular time intervals. For example, a personality or aptitude result to be recommended to the user may be predicted by measuring the similarity for each personality or aptitude type and statisticizing the measurement values of the all markings, or using a continuous pattern classification. 
     When the personality or aptitude of the user is predicted ( 231 - 3 ) based on both the voice data  211 - 3  and the voice style  211 - 5 , the personality or aptitude to be finally recommended to the user may be predicted by statistically processing the result predicted by the first engine and the result predicted by the second engine, or the personality or aptitude to be finally recommended to the user may be predicted by statistically processing the result predicted by the first engine and the result predicted by the third engine. 
       FIG.  5    shows a process of analyzing visual information in accordance with an exemplary embodiment of the present disclosure. 
     Referring to  FIG.  5   , first, a face  270  of the user is recognized in visual information (Face recognition) and the face  270  of the user is cropped. When there are two or more people in the visual information, anyone other than the target person may be deleted, and parts other than the face may also be deleted. 
     Next, based on the visual information, face data  213 - 3  that is markable on the timeline as one scene of a specific image (still) or the entirety of the specific image (video) is generated. 
     Next, based on the visual information, a face style  213 - 5  is generated that includes at least one of the shape and size of the face (Face Shape/Size), the shape and position of the eyes (Eyes Shape/pts), the shape and position of the nose (Nose Shape/pts), the shape and position of the mouth (Mouth Shape/pts), the shape and position of the ears (Ears Shape/pts), the shape and position of the eyebrows (Eyebrows Shape/pts), a facial expression (Facial Expression), and a hairstyle (Hair Shape). In addition, the face style may further include separately recognized information such as glasses, piercings, and beards. The face style may be input data for predicting personality or aptitude or input data for predicting personality or aptitude in the form of marking on the timeline. 
       FIG.  6    shows a process of analyzing personality or aptitude using visual information in accordance with an exemplary embodiment of the present disclosure. 
     Referring to  FIG.  6   , the prediction of personality or aptitude may be performed based on at least one of the face data  213 - 3  and the face style  213 - 5 , and the personality or aptitude may be predicted ( 233 - 3 ) through the machine learning (or deep learning) engine  233 - 5  and training may be performed in real time. Face personality or aptitude datasets  233 - 7  include at least one of data in which the personality or aptitude is classified according to the face data  213 - 3  and data in which the personality or aptitude is classified according to the voice style  211 - 5 . 
     When the personality or aptitude of the user is predicted ( 233 - 3 ) based on the face data  213 - 3 , the personality or aptitude of the user may be predicted by a fourth engine trained with training face data classified for each personality or aptitude type, by using the face data  213 - 3  as an input, and for example, similarity may be measured for each personality or aptitude type and the personality or aptitude with high similarity may be predicted as a personality or aptitude result to be recommended to the user. The personality or aptitude of the user that has been predicted based on the face data  213 - 3  is recommended to the user ( 250 ), and an avatar corresponding to the predicted personality or aptitude of the user is recommended ( 270 ). 
     When the personality or aptitude of the user is predicted ( 233 - 3 ) based on the face style  213 - 5 , the personality or aptitude of the user may be predicted ( 233 - 3 ) by a fifth engine trained with a training face style classified for each personality or aptitude type, by using, as an input, a 2D or 3D face pattern generated based on the face style in the one scene of the specific image that is easy to read. For example, the similarity may be measured for each personality or aptitude type and a personality or aptitude with a high similarity may be predicted as a personality or aptitude result to be recommended to the user. The personality or aptitude of the user that has been predicted based on the face style  213 - 5  is recommended to the user ( 250 ), and an avatar corresponding to the predicted personality or aptitude of the user is recommended ( 270 ). 
     As another method, when the personality or aptitude of the user is predicted ( 233 - 3 ) based on the face style  213 - 5 , the personality or aptitude of the user may be predicted ( 233 - 3 ) by a sixth engine trained with a training face style classified for each personality or aptitude type, by using, as an input, a 2D or 3D face pattern generated based on the face style marked by time for the entirety of the specific image. For example, a personality or aptitude result to be recommended to the user may be predicted by measuring the similarity for each marking and finally statisticizing the measured similarity. 
     When the personality or aptitude of the user is predicted ( 233 - 3 ) based on both the face data  213 - 3  and the face style  213 - 5 , the personality or aptitude to be finally recommended to the user may be predicted by statistically processing the result predicted by the fourth engine and the result predicted by the fifth engine, or the personality or aptitude to be finally recommended to the user may be predicted by statistically processing the result predicted by the fourth engine and the result predicted by the sixth engine.
