Image result for ui vs ux

As the Internet of things, mobile, and cloud computing technologies have evolved, interface technologies have evolved into CUI, GUI, and NUI, and another form of UI/UX is expected to be developed in the future. UX is User Experience. UX design is a still a relatively new field, with many companies only just waking up to the fact that they need someone on their payroll if they want to succeed in attracting and retaining customers. Part of the confusion might lie in the name: UX design. For many people, the word “design” is associated with creativity, colors and graphics, when really its true definition lies in functionality, as well as the process behind making products that provide a seamless experience for the people who use them. UX designer’s job will probably seem mysterious at first (“Wait, you don’t make graphics?”) and confusing at best. (“Why is the new designer interviewing people?”). Knowing who the target customers are, and how to make their experience with your product the most rewarding or ‘delightful’ it can be, is the responsibility of the UX design team. As such, ‘functionality’, ‘usability’ and ‘user adaptability’ ranks high in their priorities for the product.

UI is User Interface. A user interface is like a joke. If you have to explain it, it’s not that good. We all know that a plane can be flown from its cockpit. The UX to fly it is there, but the controls are arranged in such a way that it’s not intuitive — it has a complicated UI. reating a great UI is a challenge, especially because it has to be intuitive. When asked in a research if people like Samsung phones or Apple phones, most people said that they like Apple. Even though both the brands have the same experience of a phone as a product, people largely preferred one over the other, why? To the question why they like Apple phones better, the response was consistent and immediate: “I find the Apple phone much more intuitive.” Interviewer’s response: “Interesting — could you give me some specific examples of how it is more intuitive?” With this question, their glee turns to shock and horror as if to say “Of course, the Apple is more intuitive — how dare you question that!” From this point, they would struggle to come up with some sort of answer, ranging from “it just is” to “it just works” to “it’s simpler” to “Apple apps have a more consistent look and feel.” Apple’s UI is embedded in the UX so well, it doesn’t even feel like it’s there. The more seamless the UI, the more intuitive the product feels.


  1. User Interface Changes.

A user interface (UI) refers to a system and a user interacting with each other through commands or techniques to operate the system, input data, and use the contents. User interfaces range from systems such as computers, mobile devices, games, etc. to application programs and content usage [4]. User Experience (UX) refers to the overall experience related to the perception (emotion and thought), reaction, and behavior that a user feels and thinks through his or her direct or indirect use of a system, product, content, or service [5]. UX is a HCI‐related concept that is widely applied not only in software and hardware development, but also in services, products, processes, society and culture. UI/UX is an interface through which a person can interact with a system or application in a computer and communication environment, which is classified into a software interface and a hardware interface [6]. The hardware interface is classified into a plug or an interface card connecting the computer and the peripheral devices, and the software interface is represented by the user interface [7]. The early interface was a Character User Interface (CUI) using characters. Subsequent interfaces were graphical user interface (GUI), such as icons and menus. With the rapid development of IT technology, interface was developed to be NUI (Natural User Interface) such as voice, motion, gesture, and biological signal recognition to understand human intention more intelligently and humanly [8]. UIs suitable for the situation are continuously being studied in various fields such as mobile, hologram, location‐based service, argument reality, game machine, and automobile, etc.

  • Changes in UI/UX Trend Design Elements

Interfaces are closely related to design and interaction. Interface design plays a role in visually linking system functions. The UX interface is also affected by the usability of the system, contents, and services, the user’s affinity, and the user’s value. This study describes the latest UI/UX [9].

1) Evolution of Minimal Design

In 2017 as well, designs that continue to use minimalist layouts while minimizing complexity appear. Minimalist design focuses attention on user contents first rather than UI, and provides an interface through clear visual communication [10].

2) Increase in Micro Interaction

Micro interaction was discussed on the Internet in 2016, and the trend is expected to continue in 2017. Micro interaction implemented in the form of a generally delicate animation plays a key role in UX design, and especially each time an app is used by a customer, thousands of micro‐interactions will increase the role of mobile devices.

3) Moving Pictures Become Popular

Vision is known as the most powerful sensation of all human senses. The image was a major factor in the long user interface design, and the success with the image was a natural springboard to gradually develop into moving pictures. The image represents one thousand words and the moving picture represents ten times more words. There’s a good reason for this, and the image is static while the moving picture is dynamic.

4) Rich color and sensuous typography

Rich color tone and color are used as user interfaces. It is also expected to be brighter by using bright colors as an interface. Thus, the UI is typographically represented using sharper color palettes, duotones, and bold gradient colors.

5) Long scrolling and parallax technique websites

Long scrolling or infinite scrolling is also expected as a standard for websites. In addition, mobile devices use the more scrolls on small screens linked with touch control types.

  • Changes in UI/UX Design Feature

By segmenting by layer from the strategy of determining the user’s purpose with the UX interface to cognitive and sensory attributes that cause user behavior to the surface, Jesse James Garrett showed the framework of UX by dividing it into Strategy, Scope, Structure, Skeleton, and Surface. Recently, the design interface for UI/UX first of all gives priority to needs [11, 12]. If you show some action plan, it empathizes first. This is to understand the users. The second is to define the goal as a project or business by defining the problem. The next step, Ideate is to find ideas and solutions. The next step is to create a UI/UX that is presented as an idea or solution in the previous step as a prototype step [13, 14]. The next step is to finalize UI/UX by reviewing and making decisions as a final step. This execution plan is shown in Figure 1 as UI/UX interface Thinking.
