Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of determining how clothing fits without a physical dressing room during online shopping, as consumers have different dimensions, affects the shopping experience.
Innovation Solution
A virtual fitting room system that uses sensors to generate a 3D garment model draped on an avatar, allowing users to adjust and modify garments using gestures, with confirmation gestures to finalize changes, and employs cloth physics technology to simulate how garments move.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physical dressing room is used to determine clothing fit, then measurement precision is improved, but loss of time and loss of substance (travel and parking) occur
Solution Approach 1:
The patent creates a virtual copy of the physical dressing room experience through a virtual fitting room system. A 3D avatar representing the user is generated, and 3D garment models are draped on the avatar to simulate fit. This virtual copying allows users to assess clothing fit without physically traveling to a dressing room, thereby maintaining measurement precision while eliminating time loss.
2Measurement precision
If 3D garment models are draped on avatars to simulate fit, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces the mechanical physical dressing room system with a computational simulation system. Instead of requiring users to physically try on clothes, the system uses computer-generated 3D garment models draped on virtual avatars. This substitution of mechanical interaction with computational modeling achieves accurate fit simulation while managing system complexity through digital rather than physical infrastructure.
Solution Approach 2:
The patent introduces a 3D avatar as an intermediary between the user and the physical garment. The avatar serves as a virtual stand-in that receives and displays the 3D garment model, allowing fit assessment without direct physical interaction. This intermediary approach simplifies the user experience while enabling precise measurement through virtual representation.
3Adaptability or versatility
If users manually adjust garment models, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service through gesture-based control, where users directly manipulate the 3D garment models using natural hand gestures captured by sensors. The system translates these gestures into automatic garment adjustments without requiring manual intervention or complex interfaces. This self-service mechanism enhances adaptability for customization while maintaining ease of operation through intuitive, natural interactions.
Data Source
AI summary
Techniques for modifying a garment based on gestures are presented herein. An access module can access a first set of sensor data from a first sensor, and a second set of sensor data from a second sensor. A garment simulation module can generate a three-dimensional (3D) garment model of a garment available for sale draped on an avatar based on the first set of sensor data and the second set of sensor data. A display module can cause a presentation, on a display of a device, of the 3D garment model draped on the avatar. Additionally, the garment simulation module can determine a modification gesture associated with the 3D garment model draped on the avatar based on the first set of sensor data and the second set of sensor data. Furthermore, the garment simulation module can modify the 3D garment model based on the determined modification gesture.
