The key differences between low-fidelity and high-fidelity prototypes are:

Low-Fidelity Prototypes:

1. Simple, rough, and basic representation

2. Quick and easy to create

3. Focus on functionality and layout

4. Often hand-drawn or sketched

5. Limited visual design and detail

6. Used for early-stage testing and feedback

7. Can be created in minutes or hours

High-Fidelity Prototypes:

1. Detailed, refined, and realistic representation

2. More time-consuming and resource-intensive to create

3. Focus on visual design, usability, and interaction

4. Often created using digital tools and software

5. Includes detailed typography, color schemes, and graphics

6. Used for later-stage testing, feedback, and finalization

7. Can take days, weeks, or even months to create

In summary, low-fidelity prototypes are fast, simple, and functional, while high-fidelity prototypes are detailed, refined, and visually realistic. Low-fidelity prototypes are used for early-stage testing and feedback, while high-fidelity prototypes are used for later-stage testing and finalization.
