Text-to-Image Mood Boards for Character Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing character customization methods face challenges such as user difficulty in generating unique ideas, susceptibility to problematic content, and combinatorial explosion of options, which existing techniques struggle to address effectively.
Innovation Solution
A method utilizing large language models (LLMs) to generate and process text-to-image models, allowing users to select images representing themes, which are then used to create personalized character customization through a text-to-image generator, enabling real-time preview of customized objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-generated lists of content are used for customization, then users can select from predefined options, but the system must honor every combination of choice leading to combinatorial explosion and requires generating all options ahead of time
Solution Approach 1:
The system pre-generates a limited set of thematic images (e.g., 4-8 images per theme category) that represent different styles or vibes rather than pre-generating all possible customization combinations. This preliminary action provides users with diverse starting points while avoiding the combinatorial explosion of pre-calculating every possible outfit combination.
Solution Approach 2:
The system dynamically generates customization options based on user selections rather than using static pre-generated lists. When users select themes and items, the system real-time generates new combinations and variations through text-to-image models, allowing the customization options to adapt and evolve based on user input rather than being fixed beforehand.
2Adaptability or versatility
If free-form text input is used for customization, then users can express their ideas freely, but users struggle to generate unique ideas and the system becomes vulnerable to problematic content
Solution Approach 1:
The system introduces an intermediary layer between user input and image generation. Instead of directly processing free-form text prompts that may contain problematic content, the system uses a curated list of safe, pre-approved themes and vibes as intermediaries. Users select from these safe themes, and the system generates images based on these sanitized inputs, filtering out potentially harmful content while maintaining customization flexibility.
Solution Approach 2:
The system changes the parameter space for text input from unlimited free-form text to a controlled set of predefined themes and vibes. This parameter transformation maintains the essence of customization (users can still express their preferences through theme selection) while constraining the input space to safe, appropriate content only.
3Productivity
If text-to-image models are used to generate custom gear, then unique personalized characters can be created, but the process requires multiple sequential steps including theme generation, image generation, and real-time preview generation
Solution Approach 1:
The system segments the customization process into distinct modular stages: (1) Theme selection stage where users choose from predefined vibes, (2) Image generation stage where text-to-image models create gear images based on selected themes, and (3) Real-time preview stage where the system generates final customized gear previews. This segmentation allows each stage to be optimized independently and simplifies the overall system architecture by breaking down the complex generation pipeline into manageable components.

AI summary
Users generate one-of-a kind custom gear (a mask in one example) by selecting four images from a mood board that ‘capture their vibe.’ The images are generated using a text-to-image model, with the text used to generate those images being generated by an LLM. In this way, a list of “vibes” is generated, followed by descriptions of images that capture those vibes which are input to the text-to-image model to generate the images to create a moodboard menu content. Once a user selects four images, the selected images' text vibe/description are passed back to an LLM which (now in real-time) generates a unique “vibe” and literal description of the gear. This description is (in real-time) passed to a text-to-image generator to give the user a preview of the gear in 3D.
