Ui designer universities are all majors in visual communication design and digital media design. The abbreviation of UID refers to the person who is engaged in the overall design of software, such as human-computer interaction, running logic and beautiful interface. UI designer, covering advanced web design and mobile application interface design, is one of the most sought-after talents in the information industry.

Not only engaged in art painting, but also need to locate the software users, use environment and use mode, and finally serve the software users. UI designers are engaged in scientific and artistic design. What they need to accomplish is, in short, a process of constantly designing visual effects for users and satisfying them.

Design is divided into three categories in terms of work content, namely, research tools, research on the relationship between human and interface, and research personnel. Accordingly, the functions of UI designers generally include three aspects: First, graphic design, that is, "artistic design" in the traditional sense. Of course, in fact, what they undertake is not art works in a simple sense, but the product "shape" design of software products.

The second is interactive design, which 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.
