Solution Overview

Problem

Current avatar animation systems generate dance animations based on pre-defined settings and do not consider the dynamic music features of songs, leading to unrealistic and unengaging animations.

Innovation Solution

Incorporating a danceability score generator that analyzes music features like rhythm, melody, and energy to inform real-time avatar animations, ensuring the animations match the music being played.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If pre-defined animation settings are used, then device complexity is reduced, but animation realism and adaptability deteriorate

Engineering Contradiction:

Improveanimation system complexityVSAvoidmusic adaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The animation system transitions from static pre-defined settings to dynamic real-time generation. The system continuously analyzes music features (tempo, rhythm, melody) and dynamically adjusts animation parameters to match the music, making the animation adaptable without requiring complex manual configuration for each scenario.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The animation system becomes self-adjusting by automatically analyzing music features and generating appropriate animations without external intervention. The system extracts musical characteristics and autonomously determines animation parameters, reducing the need for complex pre-programming while maintaining high adaptability.

Inventive Principle:

Principle #25Self-service

2Manufacturing precision

If music feature analysis is implemented, then animation realism is improved, but computational complexity increases

Engineering Contradiction:

Improveanimation precisionVSAvoidprocessing complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system extracts only the essential music features (tempo, rhythm, melody) required for animation generation, rather than analyzing all musical attributes. This selective extraction reduces computational complexity while maintaining sufficient precision for creating realistic dance animations that match the music.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If real-time animation generation is used, then user engagement is improved, but processing time increases

Engineering Contradiction:

Improveuser engagementVSAvoidprocessing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of music features as the music plays, continuously extracting tempo, rhythm, and melody characteristics in real-time. This ongoing preliminary analysis allows the system to quickly generate appropriate animations without requiring extensive processing when animations are requested, reducing perceived processing time while maintaining high user engagement.

Inventive Principle:

Principle #10Preliminary action

AI summary

Method of generating a real-time avatar animation using danceability scores starts with a processor receiving a real-time acoustic signal comprising acoustic segments. The processor generates using a danceability neural network a danceability score for each of the acoustic segments. The processor generates a real-time animation of a first avatar and a second avatar based on the danceability score and avatar characteristics associated with the first avatar and the second avatar. The processor causes to be displayed on a first client device the real-time animation of the first avatar and the second avatar. Other embodiments are described herein.
