Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing motion editing techniques are cumbersome for animators when editing synchronized multi-character motions, as they require manual maintenance of interpersonal constraints, making it difficult to efficiently edit synchronized motions in both space and time.

Innovation Solution

A motion editing system that combines spatial path editing and time warping using a Laplacian motion editor and discrete motion editor, allowing for interactive manipulation and refinement of character data with user-defined constraints, including spatial and temporal constraints, to seamlessly integrate discrete and continuous editing capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing motion editing techniques are used to edit synchronized multi-character motions, then individual character motions can be manipulated independently, but manual maintenance of interpersonal constraints is required making the process cumbersome

Engineering Contradiction:

Improveease of editing synchronized motionsVSAvoidcomplexity of maintaining interpersonal constraints

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the editing of multiple synchronized characters into a unified framework where spatial path editing, time warping, and interpersonal interactions are handled together through a single motion editing interface, eliminating the need for separate manual constraint maintenance

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system introduces an intermediary constraint satisfaction mechanism that automatically manages interpersonal constraints between characters, acting as a mediator that resolves synchronization requirements without requiring direct manual intervention from the animator

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If discrete editing capabilities are incorporated into interactive manipulation interfaces, then discrete and continuous path editing can be combined seamlessly, but the system complexity increases

Engineering Contradiction:

Improveversatility of editing capabilitiesVSAvoidcomplexity of integrating discrete and continuous editing

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motion editing system is designed with multi-functionality to handle both discrete transformations (insertion, deletion, replacement) and continuous path editing within a single unified interface, allowing the same system to perform diverse editing operations seamlessly

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Disclosed are a system and a method for motion editing multiple synchronized characters. The motion editing system comprises: a Laplacian motion editor which edits a spatial route of inputted character data according to user conditions, and processes the distortion of the interaction time; and a discrete motion editor which applies a discrete transformation while the character data is processed.
