UI, namely UserInterface, is the overall design of human-computer interaction, operation logic and beautiful interface of software. Good UI design not only makes the software personalized and tasteful, but also makes the operation of the software comfortable, simple and free, which fully embodies the positioning and characteristics of the software. In layman's terms, UI can be said to be a device that everyone can interact with. Just like the earliest microcomputers, the main operating interfaces were buttons and light bulbs (so the early user interface (UI) didn't have a display screen). However, with the development, the light bulbs are getting smaller and denser, and the display screen size and image quality have been significantly improved. At this time, the display screen appeared. Later, people found that images can make machines communicate with users better, and images are widely used in information exchange between devices and people. So later, GUI appeared, which is the so-called graphical interface, which is the general UI (interface). 2. The history of 2.UI design? Perhaps many people have only come into contact with the term UI in recent years, but in fact, UI design has always existed in the design field. From the electronic products and software we first used to the construction of websites, these are all UI categories, and everything in the computer display screen we are using now is also UI. It can be said that since the design industry came into being, the term UI has actually appeared. So, why is "UI" only familiar to everyone in recent years? Because more and more enterprises realize the importance of design and the influence of user experience on products, that is, user experience. 1. The appearance of early UI Windows1.0 (1985) The early operation interface of MAC Tetris (1invented by Russian Alexis PaKinov in June, 985) advertising light box, flashing words and pictures on the screen 2. The appearance of mobile phone UI was earlier, but what really caught the eye was the appearance of iPhone. At the same time, the UI industry has sprung up in China, and more and more designers have stepped into this industry. The rise of UI: Are mobile phones and tablets the mainstream UI forms? Now the effect and technology are more and more mature. The user experience of WebUI is becoming more and more professional, and it also attaches great importance to the user experience. ? 3. What is the current status of 3.UI design? With the change of time, the market has undergone a reshuffle, brushing off many Internet companies, and the relationship between supply and demand has changed. Many small companies have developed and started to improve the professional quality of UI designers. Many designers who graduated from training courses have flooded into the workplace, and the competitiveness of their positions has also increased. ? Internet technology is changing with each passing day. From web to app, more new things such as AR and AI appear. This also requires UI designers to improve their skills and professionalism, from simple static UI production to dynamic effects, as well as cool 3D effects and the ability to make prototypes. What are the roles of UI designers? The functions of UI designers generally include three aspects: 1, and graphic design is "artistic design" in the traditional sense. Of course, in fact, what they undertake is not the art work in a simple sense, but the product "shape" design of software products. ? 2. Interaction design mainly lies in designing the operation flow, tree structure and operation specification of the software. What a software product needs to do before coding is interaction design, interaction model and interaction specification. ? 3. User testing/research The so-called "testing" here aims to test the rationality of interactive design and the aesthetics of graphic design, mainly by measuring the rationality of UI design in the form of target user questionnaires. Without this test and research, the quality of UI design can only be judged by the experience of designers or the aesthetics of leaders, which will bring great risks to enterprises. ? UI design position promoted to junior designer-intermediate designer-senior designer-senior designer-supervisor-director? You can also take the product route: UI designer-interaction designer-product manager-product director? According to the particularity of the company, the designer's work content will be different. Designers at different stages have different work contents, which can be roughly divided into: executive layer-consulting layer-management layer. ? What is the development trend of UI design? In the UI of understanding requirements, we will find that whoever knows more has the right to speak. Give the requirements to UI designers, who can understand the products, UE, user experience and data, or ask for openness to catch up with the development in restoration. Simple UI designers almost no longer exist in Silicon Valley. If a visual designer doesn't understand products, interactive design and user experience design, there is basically no way out. ? A user-friendly UI, various special events, and festive mood will inevitably require a large number of operational UI designers. Get rid of the restrictions of norms, get rid of the flat demand, and the literacy of graphic design ability, hand-painted modeling ability and creative expression ability is really pulled out of competition. Can write code UI, understand dynamic effects, understand codes, build websites and independently complete H5 promotion pages. It would be better if you could understand those programs in the background. From the perspective of stable company scale, the general small companies are all designed by 1-2 and developed by 6- 10, so development is essential in the future (but in fact, the development field is also subdivided). So all-pass, but not very experienced, full-stack designers are very popular at any time. Can the UI with special effects do animation, modeling and animation? Will open the door to a new world. ?
