What is a wireframe?
A wireframe is a diagram, structure, overview, blueprint, arrangement of user interface elements. It is also known as a mockup. The purpose of wireframing is to help system designers, programmers and users to communicate about the structure of the system and understand the same overview. Users can leave comments, ask for modification, or make a mutual agreement with the system developer before proceeding the task.
Creating the wireframe makes it easier to develop the system. Moreover, it can reduce errors and misunderstandings which may cause more time spent due to system modification.
The wireframe may be designed by sketching on paper, or using a computer program or an online website providing both free and paid version.
There are 3 levels of wireframe as follows.
- Low-fidelity wireframes: Sketch a rough idea on paper or a program
- Medium-fidelity wireframes: Define specific elements on the screen
- High-fidelity wireframes: Put more realistic details and positioning, and define wordings nearly same with the actual use.
