User Interface Design (UI Design)

In general, UI design principles revolve around a user-friendly result. Developers and engineers should look at what is most convenient for a user audience, as well as the requirements of the system and other aspects of research that feed into UI design.

Some developers also consider the principle of consistency in UI design essential, where consistent visual, functional or control elements flow through the interface's different parts. It is also important to make interfaces easy to navigate and set up clear and accessible controls. Messaging is also important because engineers must respond to the reality of different user events and different types of errors or problems, such as:

• Hang-ups
• Crashes
• Dead screens

These and many other other common issues of different kinds of interfaces, such as the familiar operating systems (OS) on personal computers, must be addressed.
