Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current technologies require professional expertise to create detailed character motions for animation movies, making it difficult for amateur users to create characters and manage their emotions effectively, as existing methods either restrict motion modifications or lack passive user control over character expressions.

Innovation Solution

A support and complement device that analyzes material and language data to deduce emotion patterns, generates motion commands based on these patterns, and synchronizes character movements with voice and sound data, allowing users to input commands to adjust and correct character motions, enabling simple creation and modification of character animations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If professional methods are used to create detailed character motions, then the quality of character animation is improved, but the complexity of operation increases making it inaccessible to amateur users

Engineering Contradiction:

Improvecharacter motion qualityVSAvoiduser operation simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system automatically analyzes voice data and material data to generate appropriate character motions without requiring user expertise. The emotion classification unit and motion generation unit work autonomously to create motions that match the content's emotional tone, allowing amateur users to achieve professional-quality animations through simple voice input

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual motion specification operations with automated emotion recognition and motion generation systems. Instead of requiring users to manually define motion parameters, the system uses emotion classification algorithms and automated motion synthesis to generate appropriate character motions from voice and material data

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If detailed motion specifications are required for character creation, then the accuracy of character expression is improved, but the time required for creation increases

Engineering Contradiction:

Improveemotion expression accuracyVSAvoidcharacter creation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-stores multiple types of motion data including emotion-based motions, default motions, and correction motions. By having these motions prepared in advance and organized in a structured manner, the system can quickly retrieve and apply appropriate motions during character creation without requiring time-consuming manual specification

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically classifies emotions from voice and material data and generates corresponding motions without user intervention. The emotion classification unit and motion generation unit work autonomously to create accurate emotion expressions, eliminating the time required for manual motion detailing while maintaining high precision

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If users are given full control to modify character motions, then the adaptability of character animation is improved, but the complexity of the system increases

Engineering Contradiction:

Improvemotion modification flexibilityVSAvoidsystem structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides motion control into distinct functional modules: emotion classification unit, motion generation unit, and motion correction unit. Each module handles a specific aspect of motion control, allowing users to interact with simple, well-defined functions while the underlying system complexity is managed through modular architecture

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary motion correction unit that mediates between automatically generated motions and user preferences. This intermediary layer allows users to provide simple correction inputs without directly managing the complex motion generation processes, maintaining adaptability while hiding system complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A support and complement device etc., are provided, which appropriately generates the character's motion for content introduction in a simple manner. The user inputs a command to an input device, which specifies the character's motion used for content introduction. The support and complement device complements the command input operation. The content includes material data and language data. The language data includes voice data to be emitted by the character. A unit for recognizing emotions analyzes the material data and the language data, and deduces the emotion pattern to be expressed by the character. A unit for choosing commands determines the character's motion using the deduced emotion pattern, command, and voice data, and generates a motion command. A unit for reading out animation movies for user's check instructs a readout device to display a proposed animation movie generated by the unit for choosing commands, thereby allowing the user to review it.
