Solution Overview

Problem

Existing emotion detection systems lack a unified, real-time processing framework capable of seamlessly integrating audio and video inputs to accurately interpret and respond to human emotions and intentions, resulting in disjointed and inaccurate interactions.

Innovation Solution

A digital character emotion response system that combines audio and video processing modules with a fusion module and a Long Short-Term Memory (LSTM) model to predict emotional states, dynamically adjusting digital character responses, and incorporates multithreaded buffering for real-time interaction with external services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If audio and video data streams are processed independently using predefined programmed logic, then processing simplicity is maintained, but interpretation accuracy of user emotional state deteriorates

Engineering Contradiction:
Improveprocessing architectureVSAvoidemotional state interpretation accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent merges independent audio and video processing streams into a unified emotion detection system. The audio processing module and video processing module are combined with a fusion module that integrates their outputs, allowing the system to interpret emotional states by综合分析 both vocal characteristics and facial expressions simultaneously, thereby improving accuracy while maintaining manageable complexity through modular design

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements a universal emotion detection framework that processes multiple modalities (audio and video) through a common architecture. The fusion module serves multiple functions by integrating features from both audio and video streams, and the emotion detection model universally handles various emotional states across different input types, reducing the need for separate specialized processing paths

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

2Device complexity

If existing emotion detection systems analyze singular modalities in isolation, then system complexity is reduced, but accuracy in interpreting true emotional state deteriorates

Engineering Contradiction:
Improvesystem architectureVSAvoidemotional state detection accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent combines singular modality processing into a multimodal fusion architecture. The fusion module integrates audio features (pitch, energy, speech rate) and video features (facial landmarks, expressions) to create a comprehensive emotional state assessment, achieving higher accuracy than unimodal systems while maintaining modular complexity through structured feature integration

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system creates a composite emotion detection approach by combining multiple input modalities (audio and video streams) with their respective feature sets. The fusion module processes this composite information using a unified model that leverages the complementary strengths of both modalities, resulting in more robust and accurate emotional state detection compared to single-modality systems

Inventive Principle:
Principle #40Composite materials

3Productivity

If digital systems process inputs without considering user emotional state, then processing speed is maintained, but user engagement and satisfaction deteriorate

Engineering Contradiction:
Improveprocessing speedVSAvoiduser engagement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary emotion detection by continuously analyzing audio and video streams in real-time before generating responses. The fusion module and emotion detection model pre-process input data to identify emotional states, allowing the system to adapt its response strategy in advance, thereby maintaining processing speed while improving user engagement through emotionally appropriate interactions

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by detecting user emotional states and using this information to dynamically adjust its responses. The emotion detection results feed back into the response generation process, enabling the system to adapt to user emotional context, which enhances user engagement and satisfaction while maintaining efficient processing through structured feedback loops

Inventive Principle:
Principle #23Feedback
