Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing virtual dressing systems fail to accurately represent the size of clothing on a user, leading to unnatural and misleading images, as they do not account for the actual size differences between real and virtual objects.

Innovation Solution

An information processing apparatus that compares the size of virtual clothing with the captured subject's dimensions and reshapes the clothing accordingly, displaying the reshaped virtual clothing to create a more natural and intuitive size representation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If virtual clothing is superimposed on the body without size adjustment, then the display process is simple and fast, but the dressing image appears unnatural and misleading

Engineering Contradiction:

Improvedisplay speedVSAvoidaccuracy of size representation

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies parameter changes by adjusting the size parameters of virtual clothing based on the captured body dimensions. The system compares the actual size of the body with the size of the virtual clothing and modifies the clothing size parameters to create a natural fit, resolving the contradiction between simple display and accurate size representation.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If virtual clothing is enlarged or reduced to match body size, then the size representation becomes more accurate, but the user cannot intuitively recognize the actual size difference

Engineering Contradiction:

Improvesize matching accuracyVSAvoidsize difference information

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies the inversion principle by keeping the virtual clothing at its original size and instead inverting the perspective by capturing the body at a reduced scale. This allows the system to maintain accurate size representation while preserving the user's ability to intuitively recognize size differences, as the virtual clothing retains its real-world proportions relative to the scaled-down body image.

Inventive Principle:

Principle #13The other way round (Inversion)

3Device complexity

If virtual clothing is superimposed without considering actual size differences, then the processing complexity is low, but the dressing image is misleading and unnatural

Engineering Contradiction:

Improveprocessing complexityVSAvoidnaturalness of representation

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent applies the copying principle by creating a virtual copy of the body from the captured image and using this copy for size comparison and virtual clothing superposition. This allows the system to process size differences accurately without requiring complex real-time measurements, as the body copy serves as a reference model that simplifies the processing while maintaining representation naturalness.

Inventive Principle:

Principle #26Copying
