UI is a small part of UX to some extent. However, UI design focuses more on colors and typography. Let’s pick a textbook example. If there need to be a button, UI designers will concentrate on the visual part. Namely, how the button will look like and what color to use, while UX designers are trying to figure out where to put it with the intention to find what users want and the resolutions to those pain points. So next time if you hear something like“building great user experiences with Silver light 4” or“Mastering HTML5, CSS3 and Jquery to implement stunning user experience”, you can just laugh it off or boo them if you want to.
If you think the definition is too hard to understand, it’s be summarized as 3 points. Maybe you can understand well.
Hope my answer is useful for you! BTW, if you’re a UI beginner or want to learn Ui. Here is an article that you have to read: How to Learn UI Design From Zero-Basis.
UI - User Interface
An User Interface is nothing but a medium through which the user could interact with the software or vice versa.
Although the several types of user interfaces the most primary types are theCommand line user interface (Where system commands are used for Interaction)and Graphical user interface(Where Graphical elements are used for Interaction )
Also now with the advent of AI Powered Digital Assistants Voice user interfaceare becoming more popular.
Voice user interfaces aim to bridge the gap between computers and humans by using a natural way of communication which is speech
What is UI design exactly?
So, what is UI? User Interface(UI), the overall design of human-computer interaction, operation logic and beautiful interface. A good UI design is to make software personalized and tasty, and easily accessible so as to adequately incarnate the orientation and feature of the software. Generally, the goal of user interface design is to produce a user interface which makes it easy (self-explanatory), efficient, and enjoyable (user-friendly) to use the software in the way which produces the desired result.
The three levels of UI design
a. Customer-centered experience research:
Exploring what are customers’ really demands through research and comparative analysis and make decisions according to users’ experience. User interface design, an integral part of the product, is a complex project with different disciplines, cognitive psychology, design, linguistics and so on, all of which play an important role in UI design. There are three principles of user interface design: setting the interface under the control of the user; reducing the burden on the user's memory; maintaining the consistency of the interface. Namely, to meet the needs of general users.
It means the interactive process of the whole project. Through the interactive design of the interface and the conduct of the product, interaction enables the product and users to establish an organic relationship so as to effectively achieve the user's goals. This is the purpose of interaction design.
One of the most important aspects of UI design: human-computer interaction.
In general, the goal of human-computer interaction engineering is to create a simple and convenient interface for users. That is to say, UI embodies user and the interface interactive search instead of the simple user interface. Therefore, as an UI designer, what we should do is design a beautiful interface as well as comfortable, simple interface that users may be satisfied with.
