UI Design - User Interface Design Here we design the way the final product should look like. Our goal is a Hi-Fi (High Fidelity) interface the users will see. The product can be tested by the customer or test user to make sure functionality is user friendly.
Interactive UX prototypes help optimize user experience under real circumstances. The prototype can be modified or redesigned during the process.
Wireframes are skechy, Lo-Fi (Low Fidelity) drawings, that show how the user interface should be working. They are a very important step on the way of development. They also help to calculate time and costs, just like necessary technical requirements.
