AI-based UI generators typically rely on datasets that contain examples of user interfaces along with structured annotations of their constituent elements. These datasets are often curated from large collections of real-world applications, websites, or design mockups and are accompanied by metadata that helps models understand the relationships between UI components (e.g., buttons, text fields, icons), their layouts, color schemes, and underlying code structures.
**Common Types of Datasets Used:**
1. **Mobile App UI Datasets:**
- **RICO Dataset:** One of the most widely cited UI datasets, RICO contains over 9,700 unique Android app screens and more than 58,000 unique UI elements, each annotated with hierarchical structures and semantic labels. This dataset enables models to learn the spatial arrangement of interface components and the semantics of common UI patterns.
- **Mobile-based Screenshot Repositories:** Beyond RICO, researchers often gather large sets of Android or iOS screenshots from app stores or scraping platforms. These can be combined with heuristics or automated tools to extract UI elements (like buttons, text, images) and their bounding boxes.
2. **Web UI and Wireframe Datasets:**
- **Web UI Datasets:** Collections of webpage screenshots and their corresponding HTML/CSS code form another core resource. By pairing rendered pages with their underlying code, models learn how visual components map to markup and style rules.
- **Wireframe-to-Code Datasets:** Some datasets consist of low-fidelity wireframes (grayscale boxes and placeholder text) paired with their corresponding high-fidelity UI code implementations. This type of data helps train models that translate abstract UI concepts into finalized, coded interfaces.
3. **Design System and Component Library Data:**
- **Component Galleries:** Design platforms like Figma, Sketch, and Adobe XD have extensive community libraries containing reusable UI components. Although not always released as a formal dataset, researchers can compile annotated data from these resources to train models in recognizing patterns, alignment constraints, and component hierarchies.
- **GitHub & CodePen Repositories:** Large amounts of open-source front-end code (HTML, CSS, JavaScript) can be mined to build datasets that show how common UI patterns are implemented. This helps models understand best practices and conventional layouts.
4. **Augmented and Synthetic UI Datasets:**
- **Procedurally Generated UIs:** Researchers sometimes create synthetic UI datasets by automatically generating layouts using predefined rules or generative adversarial networks. While these might be simpler or less realistic, they are useful for controlled experiments and pre-training models on certain patterns.
- **Annotation Transfer Techniques:** Tools that detect layout structures and element bounding boxes on arbitrary images can augment smaller datasets, increasing diversity and helping models generalize better.
5. **Multimodal Datasets (Images + Natural Language):**
- **Paired UI & Descriptions:** Some projects compile datasets where each UI screenshot is paired with a textual description of the interface’s purpose, style guidelines, or accessibility features. This enables training of models that understand UI context not just visually, but also semantically, helping with tasks like “generate a login screen with a remember-me checkbox and a submit button.”
**Key Characteristics of a Good UI Dataset:**
- **Diversity of UI layouts and visual styles:** Ensures models learn to handle multiple design genres (e.g., minimalistic dashboards, content-heavy news sites, complex mobile app menus).
- **Rich Annotation:** Every element should ideally have metadata (type of element, function, screen region, hierarchical structure).
- **Code-Image Pairing:** Having both the rendered UI image and the underlying code (HTML/CSS or Android XML) allows for learning a direct mapping from visual appearance to structural representation.
By combining these sources—RICO and other screen-level datasets, web-based paired code-image datasets, community design libraries, and synthetic or augmented sets—developers can create robust training corpora for AI systems that generate or assist with UI design.
