Avatar Communication Node Managing Identity and Expression Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR), virtual reality (VR), and mixed reality (MR) systems face challenges in securely managing avatar communications, particularly in preventing fraudulent usage and protecting user identity and expression codes from interception during real-time communication sessions.
Innovation Solution
The proposed solution involves a communication node, such as an application server node (ASN-A), that manages a universal prior model (UPM) for avatars, generating and rendering 3D video media based on received identity and expression codes, while keeping sensitive information within the sender's network, and synchronizing audio and video streams using real-time transport protocol (RTP) messages.

Engineering Contradiction Analysis
1Adaptability or versatility
If avatar-based communication is implemented in AR/VR/MR systems, then user identity and expression codes can be transmitted for rendering, but security vulnerabilities arise allowing fraudulent usage and interception of sensitive information
Solution Approach 1:
The patent introduces an application server as an intermediary between the first and second wireless communication devices. The server receives identity codes, generates avatar models, and manages expression codes, preventing direct exposure of sensitive data between devices. This mediator architecture secures the communication by centralizing sensitive data management on the server side.
Solution Approach 2:
The system segments the avatar communication process into distinct components: identity code transmission, avatar model generation, expression code transmission, and video rendering. This segmentation allows each component to be secured independently, with the server handling sensitive identity data and clients handling expression data and rendering.
2Manufacturing precision
If detailed avatar information is transmitted during communication sessions, then realistic avatar representation is achieved, but bandwidth consumption and data transmission overhead increase
Solution Approach 1:
Instead of transmitting original high-resolution video or detailed 3D model data, the system uses expression codes that reference pre-generated avatar models stored on the server. The server synthesizes realistic avatar video by applying expression codes to the base model, dramatically reducing uplink bandwidth requirements while maintaining high rendering quality.
Solution Approach 2:
The avatar model is generated in advance from the identity code before the communication session begins. This preliminary generation allows the detailed 3D model to be created once and stored, eliminating the need to repeatedly transmit large model data during the session. Only lightweight expression codes need to be transmitted in real-time.
3Ease of operation
If real-time synchronization of audio and video streams is implemented, then seamless communication experience is provided, but system complexity and processing requirements increase
Solution Approach 1:
The application server acts as a synchronization coordinator, receiving expression codes with timing information and generating corresponding video frames. The server handles the complex synchronization logic centrally, reducing the processing burden on client devices while ensuring precise audio-video alignment through centralized timestamp management.
Data Source
AI summary
Systems and methods for managing avatar communications may include a wireless communication node which receives a data packet from a first wireless communication device. The data packet may include an identifier corresponding to a user of the first wireless communication device. The wireless communication node may generate an avatar for the user according to the identifier, receive an expression code from the first wireless communication device, and/or configure the avatar for the user according to the expression code. The wireless communication node may transmit video data corresponding to the avatar to an address of a second wireless communication device.
