Avatar Interaction Triggers in 3D XR Scene Descriptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual conferencing systems lack a solution to manage interactions between avatars independently from scripts specific to a given user equipment, failing to link these interactions seamlessly with the entire 3D scene.
Innovation Solution
A scene description method that includes dedicated semantics to manage avatar interactions, utilizing a scene description file to track events and execute appropriate actions based on triggers related to avatar expressions, gestures, and gaze, independent of user equipment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If avatar interactions are managed using equipment-specific scripts, then the interactions can be controlled according to specific user equipment capabilities, but the interactions cannot be independently managed from the 3D scene and lack portability across different platforms
Solution Approach 1:
The patent introduces a scene description file as an intermediary that mediates between the 3D scene and avatar interactions. This file contains dedicated semantics for defining avatar interaction triggers and actions, allowing interactions to be managed independently from equipment-specific scripts while maintaining portability across different platforms. The scene description file serves as a universal language that bridges the gap between diverse user equipment and the virtual conferencing application.
Solution Approach 2:
The patent segments the avatar interaction management into distinct components: triggers (events to monitor), actions (responses to execute), and the scene description file (configuration container). This segmentation allows each component to be independently defined and managed, enabling portable interaction definitions that can be applied across different user equipment without requiring equipment-specific scripting.
2Ease of operation
If avatar interactions are decoupled from the 3D scene, then equipment-specific control is simplified, but the interactions fail to link seamlessly with the entire 3D scene
Solution Approach 1:
The scene description file serves multiple functions simultaneously: it defines the 3D scene structure, specifies avatar interaction triggers and actions, and maintains references to scene nodes. This multi-functionality ensures that avatar interactions remain tightly integrated with the 3D scene while preserving ease of operation through a unified configuration file that can be processed consistently across different platforms.
3Manufacturing precision
If comprehensive scene description is provided for all avatar interactions, then interaction accuracy and synchronization are improved, but data transmission and processing complexity increase
Solution Approach 1:
The patent changes the parameter organization by defining interaction parameters (triggers, actions, node references) in a structured scene description file format. This parameterization allows comprehensive interaction definitions to be maintained with high precision while reducing processing complexity through standardized data structures that can be efficiently parsed and executed across different user equipment.

AI summary
Methods, apparatus and data stream are provided for processing of triggers related to avatar interactions in a 3D scene. A scene description file is received. A user equipment or an application server parses the file and iterates on each described behavior. If triggers in the scene description are related to avatar interactions the device starts tracking the avatars and the events (expressions, gestures and/or gaze) referenced in these triggers. Each time an event occurs and is detected the device starts the one or more actions specified in the corresponding behavior.
