Solution Overview

Problem

Existing augmented reality systems struggle to accurately display avatars with synchronized mouth movements in real-time, particularly when processing voice data, leading to delays and inconsistencies.

Innovation Solution

An electronic device with multiple processing circuits is used to identify voice data features at different speeds, allowing for the generation of mouth shapes based on these features, and displaying avatars with synchronized mouth movements using a combination of hardware and software components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single processing circuit is used to process voice data for avatar mouth synchronization, then device complexity is reduced, but processing speed and synchronization accuracy deteriorate

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSSpeed

Solution Approach 1:

The patent divides the processing circuit into multiple independent processing units, each capable of handling different aspects of voice data processing simultaneously. This segmentation allows parallel processing of voice features, improving overall processing speed while maintaining manageable device complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The processing circuits are designed with multi-functional capabilities to handle various voice processing tasks (feature extraction, analysis, synthesis) within a unified hardware framework. This universality reduces the need for separate dedicated circuits for each function, balancing processing power with device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple processing circuits are used to process voice data in parallel, then processing speed improves, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The processing system is segmented into specialized processing circuits that can operate in parallel. Each circuit handles specific voice processing tasks, enabling high-throughput processing while keeping individual circuit complexity low through functional decomposition

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a hierarchical processing architecture where simpler processing units are nested within more complex coordination structures. This nesting allows multiple processing circuits to work together efficiently under unified control, managing overall system complexity while maintaining high processing productivity

Inventive Principle:

Solution Approach 1:

The system performs preliminary processing of voice data to extract essential features before full avatar rendering. By pre-processing and identifying key voice characteristics in advance, the system reduces subsequent processing time while maintaining accuracy in mouth shape identification through focused feature analysis

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies partial processing strategies where not all voice data aspects are processed with equal depth. Critical features for mouth synchronization are processed with high accuracy, while less critical aspects use faster, less computationally intensive methods, achieving acceptable overall accuracy with reduced latency

Inventive Principle:
Principle #16Partial or excessive action
