Virtual Avatar Interaction in Video Sessions for Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in video sessions are reluctant to share their real images due to privacy concerns, necessitating a solution that enhances privacy while maintaining efficient data transmission.
Innovation Solution
A method and apparatus that replaces a user's real image with a virtual image, controlled by movement information to perform interaction actions, reducing the need for transmitting real images and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real images of users are transmitted and displayed in video sessions, then interaction authenticity is improved, but user privacy is compromised
Solution Approach 1:
The patent applies the copying principle by replacing real user images with virtual images that replicate user actions and expressions. The virtual image is generated based on user movement information and interaction data, creating a copy that maintains interaction authenticity while eliminating the need to transmit and display actual real images, thus protecting user privacy.
2Measurement precision
If real images are transmitted in video sessions, then user identity representation is accurate, but data transmission volume increases
Solution Approach 1:
The patent extracts only the essential movement information and interaction data from the user's real actions, discarding the bulk of the real image data. Instead of transmitting complete real images, the system extracts key movement parameters and uses these to generate virtual images, significantly reducing data transmission volume while maintaining accurate user identity representation through the virtual avatar.
3Object-affected harmful factors
If virtual images are used to replace real images, then user privacy is protected and data transmission efficiency is improved, but interaction complexity increases
Solution Approach 1:
The patent introduces a virtual image as an intermediary between the user and the communication system. The virtual image serves as a mediator that translates user movements and interactions into visual representations without requiring direct transmission of real images. This intermediary approach simplifies the overall system by providing a straightforward replacement mechanism while protecting privacy and reducing data transmission requirements.

AI summary
Embodiments of this application provide a method and apparatus, a terminal and a medium. The method includes the following steps. A target terminal displays, in a video session, a video session interface including an image display region for displaying images associated with one or more users participating in the video session. The target terminal displays a target virtual image of a user of the target terminal in the image display region. The target terminal acquires movement information of the user and controls the target virtual image displayed in the image display region to perform a target interaction action corresponding to the movement information of the user. Finally, the target terminal transmits movement data of the target virtual image performing the target interaction action, to terminals of the other users of the video session to render the target virtual image to perform the target interaction action on the corresponding terminals.
