When we design apps for clients, we often talk about “UI Design”. But what does UI Design really mean? This article explains the basics and introduces four practical principles.
What Is UI Design?
UI stands for User Interface. It is the medium through which a system and a user interact and exchange information. UI Design covers the logic of operation and the visual design of the interface, making the user experience simpler, clearer and more comfortable.
Four Principles of UI Design
Create easier tap targets. Many users have experienced buttons that need to be tapped several times before responding, or systems that fail to recognize a tap accurately. From a UI Design perspective, this is not acceptable. When designing an app, input fields, buttons and other tappable areas should have larger response zones so users can complete actions more easily.
Use graphics to support text. App layouts can use visual elements to separate different levels of text and make priorities clearer. When alignment, spacing, size and colour are handled well, the interface becomes cleaner and easier to read.
Images can also support information that is difficult to explain through text alone. For example, in a party room booking app, users may not understand the room clearly from written descriptions only. Photos of the party room can help users understand the product more quickly.
Place function buttons logically. Some functions appear in almost every app, such as edit, back, delete and add. To create a smoother user experience, these buttons should be placed where users naturally expect them. For example, a back button is usually placed at the top left of the screen, not at the bottom centre. Designers can refer to iOS and Android interface conventions before developing the app design.
Set one primary colour. More colours do not necessarily mean better design. A harmonious colour system is more effective. In most cases, one primary colour with two supporting colours is enough. Too many colours on one screen can distract users. Neutral colours such as black, white and grey can also work well, with stronger colours reserved for areas that need attention.
