majiayu000 UX Prototyping
Create interactive prototypes to visualize, test, and refine digital product designs before development.
Overview
UX prototyping involves creating preliminary versions of digital products to test functionality, gather feedback, and refine designs. Prototypes range from simple sketches to fully interactive mockups.
Wireframing
Purpose of Wireframes
What Wireframes Are:
- Skeletal blueprints of interfaces
- Focus on structure and layout
- Low-fidelity representations
- No detailed visual design
- Emphasize functionality
Benefits:
- Quick and inexpensive
- Easy to iterate
- Focus on UX, not aesthetics
- Facilitate communication
- Identify issues early

Mid-Fidelity:
- More defined layout
- Basic typography
- Spacing and alignment
- Some UI elements
- Digital tools
High-Fidelity:
- Detailed layout
- Actual content
- Refined UI elements
- Near-final design
- Interactive elements
