Solution Overview

Problem

Conventional conferencing software lacks the capability to dynamically set virtual backgrounds that reflect the current characteristics of conference participants, leading to a lack of engagement and interest.

Innovation Solution

Implementing dynamic, participant-aware virtual backgrounds using VBG rules that allow conferencing software to change backgrounds based on participant characteristics, enabling the selection of VBG rules that set virtual backgrounds from virtual background sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional conferencing software uses static virtual backgrounds, then the system complexity is low, but participant engagement and interest are reduced

Engineering Contradiction:

Improveadaptability of virtual backgroundsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic virtual backgrounds that automatically adapt to conference participants based on real-time characteristics such as role, location, and conference context. The system transitions from static background images to dynamically generated backgrounds that change according to participant attributes, thereby improving adaptability while managing complexity through automated rule-based generation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables virtual backgrounds to self-generate and self-adjust based on participant characteristics without requiring manual configuration for each user. The automated background generation system monitors participant data and automatically applies appropriate backgrounds, reducing the operational burden while enhancing adaptability

Inventive Principle:

Principle #25Self-service

2Ease of operation

If dynamic participant-aware virtual backgrounds are implemented, then participant engagement is enhanced, but system complexity increases

Engineering Contradiction:

Improveuser experience qualityVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system continuously monitors participant characteristics and conference context, using this feedback to automatically adjust and personalize virtual backgrounds in real-time. This closed-loop approach enhances user experience by making backgrounds responsive to participant needs while managing complexity through automated decision-making algorithms

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system pre-establishes a library of virtual backgrounds and defines generation rules in advance, allowing rapid deployment of personalized backgrounds without complex real-time processing. By preparing background options and decision logic beforehand, the system enhances user experience while controlling operational complexity

AI summary

A background setting request that identifies a virtual background (VBG) rule that identifies a VBG source is received from a conference participant of a video conference. A request for a VBG datum is transmitted to the VBG source, wherein the request transmitted to the VBG source includes a callback handler that receives the VBG datum from the VBG source. An aspect of a source output image of the conference participant is then set based on the VBG datum.
