UE (User Experience) : User experience

UI (User Interface): user interface

UCD (User Centered Design): user centered design

UED (User Experience Design): user experience design

UI (User Interface) is the user interface, also known as human-computer interface. It refers to the collection of interaction methods between users and certain systems. These systems not only refer to computer programs, but also include certain machines, equipment, complex tools, etc.

Software design can be divided into two parts: coding design and UI design. Everyone is familiar with code design, but UI design is still a strange word. Even some people who are specialized in website and multimedia design do not fully understand the meaning of UI. The original meaning of UI is user interface, which is the abbreviation of User and interface. Literally, it is two components of user and interface, but actually it also includes the interaction between user and interface.

Interface design. In the long development of software, interface design has not been paid attention to. People who do interface design are also called "artists" in a derogatory sense. In fact, software interface design, like the industrial modeling design of industrial products, is an important purchase point of products. A friendly and beautiful interface will bring you comfort vision Enjoy, shorten the distance between people and computers, and create selling points for businesses. Interface design is not a simple art painting. It needs to locate users, use environment, use methods and design for end users. It is a purely scientific art design. The standard for testing an interface is neither the opinion of a project development team leader nor the result of project members' voting, but the feelings of the end user. Therefore, interface design should be closely combined with user research, which is a process of constantly designing satisfactory visual effects for end users.

   Interaction design (Interaction Design), as a new discipline focusing on interactive experience, came into being in the 1980s. It was proposed by Bill Mogrich, a founder of IDEO, at a design conference in 1984. At first, he named it "Soft Face", because this name is easy to remind people of the popular toy "Cabbage Patch doll" at that time, He later renamed it "Interaction Design" - interaction design.

UED is one of the main forces in product planning. They use their knowledge, experience and design ability to come up with design schemes. ED is not only an Internet expert, but also an industry expert. Be able to use their Internet knowledge to design the operation that industry experts want to achieve, and put it into commercial marketing.

In short, when designing products, we should start from the needs and feelings of users, and design products around users instead of letting users adapt to the products. Regardless of the product use process, product information architecture, human-computer interaction mode, etc., we need to consider the user's use habits, expected interaction mode, visual experience, and other aspects.

A good user centered product design can be measured by the following dimensions: the effectiveness, efficiency and satisfaction of the product when it is used for a specific purpose for a specific user in a specific use environment The degree of attraction to users, the overall psychological feelings of users before and after experiencing the product, etc.

UCD is the future company It is necessary to carry out network services, so UCD positions will also be a trend.

User Experience (UE for short) is a purely subjective psychological feeling established by users in the process of using a product (service). Because it is purely subjective, it has certain uncertainties. Individual differences also determine that the real experience of each user cannot be completely simulated or reproduced through other ways. But for a well-defined user group, the commonness of its user experience can be recognized through well designed experiments.

User experience mainly comes from the interaction process between user and human-computer interface. In the early software design process, the human-computer interface was regarded as just a "package" wrapped outside the function core without sufficient attention. The result is that the development of human-computer interface is independent of the development of functional core, and often starts at the end of the whole development process. This way greatly limits the design of human-computer interaction, and the results are risky. Because the design cost of modifying the function core in the final stage is huge, the only way is to sacrifice the human-computer interface. This kind of speculative and gambling development is almost difficult to obtain a satisfactory user experience. As for customer service, it is also part of the user experience in a broad sense, because it is inseparable from the design of the product itself. Customer service is more about the quality of personnel, and it is difficult to change the products that have been completed and put into the market. But a good design can reduce users' demand for customer service, thus reducing the company's investment in customer service, and also reducing the probability of user churn caused by customer service quality.

Interaction design is a discipline that pays special attention to the following contents:

1. Define the product form closely related to the behavior and use of the product.

2. Predict how the use of the product affects the relationship between the product and the user, as well as the user's understanding of the product.

3. Explore the dialogue between products, people and material, culture and history.

Interaction design solves product design from the perspective of "goal orientation":

1. It is necessary to form an opinion on how people want to use the product and why people want to use that product.

2. Respect users and their goals.

3. For product features and use attributes, there should be a complete form, not too simple.

4. Looking into the future, to see what products might look like, they are not necessarily like the current situation.
