[0065] The realization of the objective, functional characteristics, and advantages of the present disclosure are further described with reference to the accompanying drawings.
[0066] It should be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.
[0067] The main solutions of the embodiment of the present disclosure are: receiving a login request sent by the user terminal through the virtual reality device; verifying the login request, and assigning a node to the user terminal, the node is deployed in a pre-created blockchain network; and receiving and processing an interaction instruction sent by the user terminal, for the user terminal perform an interaction action based on the node. Through the information interaction between the server and the user terminal, each user terminal in the educational community service system communicates and chooses to execute interaction actions based on the corresponding nodes, which can solve the problem of centralized operation limitations and improve the sense of experience and simplicity. Based on the solutions of the present disclosure, starting from the problem that educational resources in the real world are limited by centralized operations, an educational community service system based on metaverse is constructed. In the educational community service system, the effectiveness of the decentralization of the educational community service method proposed in the present disclosure is verified, and the experience and simplicity of the user terminal are improved.
[0068] The embodiments of the present disclosure consider that the cloud servers that students and teachers access are often operated by schools or third-party institutions. Under such a system architecture, teachers’ teaching must rely on the centralized servers of their schools or third-party institutions, and is subject to regional restrictions. Second, when teachers teach online, they can only communicate with students through video calls, and students do not feel like they are there when they are learning. Moreover, many students are still accustomed to traditional offline learning methods, so online learning cannot bring students a good experience.
[0069] Therefore, in the solutions of the embodiments of the present disclosure, starting from the problem that educational resources in the real world are limited by centralized operations, combined with the performance capabilities of virtual technology in visual processing, a decentralized educational community service system based on the metaverse and blockchain network 1s designed, which can solve the problem of centralized operation limitations, and improve the sense of experience and simplicity.
[00790] In the various embodiments below, it should be understood that the user terminal refers to the terminal used by the user, and the user terminal also includes a student terminal, a teacher terminal, a questioning terminal and an answering terminal. These terminals can be all devices including AR and VR, as well as smart phones, tablet computers, notebook computers, desktop computers, wearable devices (such as smart watches, AR and VR helmets, AR and VR glasses), or the like. The above terminal generally needs to perform the relevant steps and processes in the educational community service system in this embodiment by setting a corresponding distributed application DAPP (such as application software on a computer, DAPP or APP on a smart phone, and a wearable device). Because in this embodiment, the entire system is built on the blockchain network, the applications carried by the terminals corresponding to each node are decentralized applications (1.e., DAPPs). In addition, it should be noted that these terminals also need to have functions that can create some kind of connection between virtual and reality, such as at least one or a combination of virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR). Terminal devices with these functions are existing technologies, such as VR devices such as Valve Index from Steam, HTC VIVE from
HTC, and Oculus quest from Oculus. Microsoft’s HoloLens (AR device), Yingchuang
Technology’s MR smart glasses Action One, etc. are on the blockchain network. Multiple user terminals can use any network connection type to access the blockchain network to become nodes. Computer programs supporting the educational community service system (such as for establishing connections, asking questions, answering questions, paying smart contracts, school models, classroom models, or the like) are simultaneously deployed in all terminals of the blockchain network nodes. Any information changes in the blockchain network (such as the information asked by the questioning terminal, the information answered by the answering terminal, the teaching information released by the teacher terminal, or the like) will be written into the blockchain maintained by all nodes.
[0071] The hardware part of the management node can use any computing device with sufficient computing power. The management node can write the school model into the blockchain maintained by each node of the blockchain network. The school model is used to observe the furnishings in the school modeling from the first perspective (or other perspectives such as the third person) after the user terminal is connected. The registration and the doctor-patient matching process are performed through AR navigation, queuing, chat, interaction, payment and other actions, to improve the user’s experience when visiting a doctor. For example, the server can use the existing 3D modeling engine to establish a managed 3D model according to the layout of the school in reality. The 3D model includes teaching buildings, road signs, gymnasiums, libraries and other furnishings. The interaction modules (such as various types of controls) can be further configured on these furnishings, and the virtual model can be sent to the management node for the roles accessed to the management node to use these interaction modules to realize interaction actions. The data generated by these interactions will also be synchronized to the entire blockchain network to implement the consensus mechanism. For example, a selection control can be configured for the library model, and when the user accesses the management node as an avatar, the user terminal can receive the user’s selection operation.
There are many kinds of selection operations of the user terminal. If a VR device is used, the selection operation can be performed by using the somatosensory hardware in the VR device.
With AR devices, selection operations can be captured through methods such as optical see-through and video see-through and specular reflection. The data generated by all user selection operations will be synchronized to the entire blockchain network for consensus.
[0072] As shown in FIG. 1, FIG. 1 is a schematic diagram of functional modules of a terminal device to which an educational community service apparatus belongs according to an embodiment of the present disclosure. The educational community service apparatus may be an apparatus independent of the terminal device and capable of information interaction between the server and the user terminal, and may be carried on the terminal device in the form of hardware or software. The terminal device may be an intelligent mobile terminal with a data processing function, such as a mobile phone or a tablet computer, or a fixed terminal device or a server with a data processing function.

Based on the solutions of the present disclosure, starting from the problem that educational resources in the real world are limited by centralized operations, an educational community service system based on metaverse is constructed. In the educational community service system, the effectiveness of the decentralization of the educational community service method proposed in the present disclosure is verified, and the experience and simplicity of the user terminal are improved.
[0115] Based on the architecture of the terminal device but not limited to the architecture, the method embodiments of the present disclosure are proposed.
[0116] As shown in FIG. 2, FIG. 2 is a schematic flowchart of an educational community service method according to a first exemplary embodiment of the present disclosure. The educational community service method is applied to a server for interacting with several user terminals. Each of the user terminals is configured with a virtual reality device, and the educational community service method includes following operations:
[0117] Operation S210, receiving a login request sent by the user terminal through the virtual reality device.
[0118] As the technology develops, the metaverse has been gradually realized. The metaverse uses various scientific technologies and high-speed computing device to build a virtual digital world that is parallel to the real world. From a technical point of view, the metaverse includes a content system, a blockchain system, a display system, and an operating system, and finally presents a 3D interface that surpasses the limitations of the screen, which is considered to be another new era after the PC era and the mobile era. To put it simply, the metaverse is a completely virtual or incompletely virtual multi-person social world, which is not only a simple social entertainment, but also a game server, and a presentation of a financial platform and a real physical space. The metaverse is the iterative evolution of the Internet ecology, the real-time information interconnection and mutual mapping between the real world and the virtual world. At the same time, this virtual world persists, which is not a copy of the real world, but another form of information existence and perception associated with the real world.
Although the metaverse has reached a certain level of maturity, it has not been well integrated and applied in all walks of life, especially in the education industry. In this context, an educational community service method is proposed.
[0119] Through all virtual reality devices including AR and VR and smartphones, tablets, notebook computers, desktop computers, wearable devices (such as smart watches, AR and VR helmets, AR and VR glasses), the user terminal selects the corresponding distributed application
DAPP (such as application software on a computer). The functions that can create a connection between virtual reality and reality include at least one or a combination of virtual reality, augmented reality, mixed reality, and extended reality. The character accessed to the school modeling can use at least one or a combination of virtual reality, augmented reality, mixed reality, and extended reality to interact. Different virtual reality devices are connected through the interface, and during the AR face-to-face teaching process, teachers can refer to the data acquired by different virtual reality devices, and enter the electronic Q&A database corresponding to the blockchain through the block method.
[0120] Users need to register as nodes in the blockchain network. As an example, the registration information may include, but is not limited to, the user’s name, virtual name, age, gender, ID number, mobile phone number, biometrics, email address, payment account information, or the like. The server stores the registration information in a cache of the memory for authenticating the user terminal. It should be understood that if users need to protect their privacy, they can choose to provide only part of the information or a virtual name during the registration process. Or even though the necessary identity information is provided, smart contracts for information protection are deployed in advance in the blockchain network, and the information that these users are unwilling to disclose will not be displayed on the terminals corresponding to other nodes in the blockchain network. For example, if the user does not want to disclose his name, he can register in an anonymous manner, or although his real name is provided, it will not be displayed to other user terminals during the interaction.
[0121] The user terminal will encrypt the user’s registration information. For example, the user terminal can generate a paired public key and private key according to a smart contract pre-deployed on the blockchain, and use the private key to encrypt the user’s registration information. It is also generally necessary to combine the registration information and the timestamp to encrypt. The user terminal also calculates index data (such as a hash value) for querying the encrypted data based on the encrypted data, and then writes the encrypted data and the index data into the blockchain together. That is, the consensus algorithm of the blockchain network is executed in the entire blockchain network and synchronized to each node in the blockchain network (including all user terminals, management nodes, and e-commerce platform nodes). The consensus mechanism itself belongs to the well-known technology in the blockchain network, such as PoW (Proof of Work), PoS (Proof of Stake) and other consensus mechanisms.
In addition, the user terminal stores the index data and the key used to decrypt the encrypted data (that 1s, the public key corresponding to the private key used when encrypting the data) in the local storage space of the user terminal, and the user terminal can obtain encrypted data from the blockchain network through the index data, and obtain user information from the encrypted data by using the key.
[0122] After the registration is successful, when selecting the corresponding distributed application DAPP, the user terminal will send a login request to the server. The login request carries the user’s verification information. The verification information may include, but is not limited to, the user’s IP information, name, virtual name, age, gender, ID number, mobile phone number, biometric features, email address, and payment account information.
[0123] Operation S220, verifying the login request, and assigning a node to the user terminal, the node is deployed in a pre-created blockchain network.
[0124] After receiving the login request sent by the user terminal, the server parses the login request, obtains the user information carried in the login request, and indexes the registration information stored in the memory when the user registers. The user information is compared with the registration information. If the user information is consistent with the registration information, it indicates that the user is a legal identity, and the server determines that the verification is passed. After the user terminal passes the verification, the server will assign the corresponding node to the user terminal according to the registration information. The nodes are deployed in the pre-created blockchain network. Verifying the login request of the user terminal by the server can ensure the legitimacy of the form data input. By assigning corresponding nodes to user terminals, not only can the minimum reliability and performance standards set by network rules be maintained, but also the privacy of interactions can be increased, allowing instant interactions and transactions.
[0125] Operation S230, receiving and processing an interaction instruction sent by the user terminal, for the user terminal to perform an interaction action based on the node.
[0126] After the user terminal successfully accesses the node, the server will receive the corresponding interaction instruction sent by the user terminal. The specific interaction instruction can be but not limited to the following:
[0127] receiving and processing a character creation instruction sent by the user terminal, for the user terminal to obtain a character model to which the current terminal belongs based on the node; or
[0128] receiving and processing a virtual teaching instruction sent by the user terminal, for the user terminal to perform virtual reality teaching based on the node; or
[0129] receiving and processing a question and answer instruction sent by the user terminal, for the user terminal to ask and/or answer a question based on the node; or
[0130] receiving and processing an announcement instruction sent by the user terminal, for the user terminal to publish or view an announcement based on the node; or
[0131] receiving and processing a transaction instruction sent by the user terminal, for the user terminal to conduct a transaction based on the node; or
