Virtual Image Video Call System for Privacy and Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video call technologies compromise user privacy and reduce communication interest by using static avatars or video pendants, which do not effectively enhance the communication experience.
Innovation Solution
A method and device for replacing video portraits with virtual images in video calls, allowing users to select or determine virtual images based on emotional information and real-time motion, and transmitting these images over a network to enhance user experience and emotional expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static pictures or video pendants are used to replace avatars in video calls, then user privacy is protected, but communication interest and user experience are reduced
Solution Approach 1:
The patent applies dynamics by transforming static avatars into dynamic virtual images that can change expressions and appearances in real-time. The virtual image generation unit creates images that dynamically respond to user emotions and contexts, making the communication more engaging while maintaining privacy protection.
Solution Approach 2:
The patent changes parameters of the virtual images including emotional expressions, appearance styles, and image characteristics. The emotional information detection unit identifies user emotions and the virtual image generation unit adjusts image parameters accordingly, providing personalized and adaptive communication experience.
2Adaptability or versatility
If real-time emotional detection and virtual image generation are implemented, then communication effectiveness and user engagement are improved, but system complexity and computational workload increase
Solution Approach 1:
The patent segments the video call system into distinct functional modules: emotional information detection unit, virtual image generation unit, and image transmission unit. This segmentation allows each module to perform its specific function independently, managing system complexity through modular design while achieving enhanced communication effectiveness.
Solution Approach 2:
The patent introduces an intermediary virtual image that mediates between the user's real emotions and the communication output. Instead of directly transmitting raw video or simple static avatars, the system uses generated virtual images as intermediaries that convey emotional information in a more engaging and privacy-protecting manner.
3Adaptability or versatility
If virtual images are generated and transmitted in real-time during video calls, then user experience is enhanced, but network bandwidth and transmission time are consumed
Solution Approach 1:
The patent creates virtual image copies that represent the user's emotional state and appearance. Instead of transmitting the actual user video feed, the system generates and transmits synthesized virtual image copies, which consume less bandwidth while providing enhanced user experience through personalized and dynamic visual representation.

AI summary
An objective of the present application is to provide a method and a device for a video call based on a virtual image. Compared with the prior art, the present application obtains first video information, and replaces a video portrait in the first video information with a virtual image, to determine second video information containing the virtual image. In this way, pleasure of communication can be increased and communication effect can be improved by using the virtual image in the video call, and thereby use experience of a user is enhanced and enriched.
