accessibility--Accessibility/Accessibility

accessibility refers to the accessibility of a Web page here. The Web page accessibility of the Consortium is defined as follows:

"Web accessibility is accessible to people with disabilities who can use the Web page without hindrance." More specifically, the usability of the web is that people with disabilities can perceive, understand, manipulate, interact with, and contribute to Web pages. Web accessibility also benefits people who are not handicapped, including those who are weakened by aging. Web page availability includes all of the effects. ”

Web usability outlines all the disabilities that affect access to or use of Web pages, including visual, auditory, physical, verbal, sensory, and neurological disabilities.

WAI (Web Accessibility Initiative) , the Web page availability initiative, uses its global organization development strategy, guidelines, and resources to help people with disabilities develop Web page availability.

Hci/chi (Human-computer interaction)--human-computer interaction

Human-Computer Interaction CHI (Computer Human interaction), also known internationally (Hci,human Computer interaction), is an interdisciplinary study that covers a wide range of topics, including cognitive science in the field of psychology, psychology System architecture technology in the field of software engineering, speech processing technology and image processing technology in the field of information processing, intelligent control technology in the field of artificial intelligence, etc.

In general, human-computer interaction is essentially a cognitive process, human-computer interaction theory is based on cognitive science; human-computer interaction is a closed-loop system, and human-computer interaction is a methodology based on system science as a framework of human-computer interaction. The theory of human-computer interaction is finally realized and applied through information technology such as modeling, formal description, integration algorithm, evaluation method and software framework of information system.

IA (Information Architecture)--Information architecture

The information architecture includes "The design of the organization, annotation, navigation, and search of the system," information architecture for the world Wide Web author Louis Rosenfeld These features help people to find and manage information more successfully "(2000).

Information architecture, or IA, is a high-level information structure designed to plan how users will ultimately get information and knowledge from the system. An information architecture architect can be considered a "system engineer" for the user Experience team, which means that he or she will be responsible for how content is organized, which page elements need to be visible or usable at any given moment, and other higher-level decisions. The information architecture Architect works directly with the director of the user Experience team to transform business requirements and user requirements into system prototypes. These prototypes are usually delivered in the form of a description chart of the system or process. The knowledge background of a good information architecture architect is usually slightly focused on engineering rather than design, and they tend to take a more pragmatic view rather than pursue innovation in the design of information structures.

Interaction design--Interactive Design

The definition of Alan Cooper

Simply put, interactive design is the behavior of artifacts, environments, and systems, and the design and definition of the elements that convey this behavior. The interactive design first plans and describes the way things behave, and then describes the most effective forms of conveying this behavior. Interactive design is a discipline that pays special attention to the following topics:

• Define product forms that are closely related to the behavior and use of the product
• Predict how the product's use affects the product's relationship with the user and the user's understanding of the product
• Explore dialogue between products, people and contexts (material, culture, and history) (Riemann and Forlizzi)

Definition of the author of the Interaction Design--beyond human-computer Interaction:

Interaction design refers to the design of interactive products that support people's daily work and life. Specifically, interaction design is about creating a new user experience that is designed to enhance and expand the way people work, communicate, and interact. Winnogard (1997) describes interaction design as "the design of human communication and interaction space"

UCD (user-centered Design)--user-centric

A successful interactive system must be able to meet the needs of the user. This means not only the ability to identify a variety of user groups, but also the skills, experience, and preferences that individual users have, but designers are not as familiar with the target audience as they think.

No clear consensus has been reached on the composition of user-centric design. But John Gould and his IBM colleagues developed a method called design-for Usability (GOU88) in the 1980s that included the most widely accepted definition. It developed from the practice of several interactive systems, the most famous of which is IBM's 1984 Olympic messaging System (GOU87). The method consists of four main parts, as follows: Focus on users, integrated design, initial user testing, iterative design.

UI (User Interface)--Interface

in the process of interaction between people and machines (Human Machine interaction), there is a level that we call the interface (interface). From the psychological point of view, the interface can be divided into sensory (visual, tactile, auditory, etc.) and emotional two levels. User interface design is an important part of screen products. Interface design is a complex engineering with different disciplines, cognitive psychology, Design science, linguistics and so on play an important role. The three principles of user interface design are: Placing the interface under the control of the user, reducing the user's memory burden, and maintaining the consistency of the interface.

gui (graphical user Interface) graphical user interface is a part of the UI

usability--availability

Availability (usability) is an important quality metric for interactive IT products/systems, refers to the product for the user is effective, easy to learn, efficient, good memory, less error and satisfactory degree, that is, the user can use the product to complete his task, how efficient, subjective feelings how, in fact, from the user's perspective to see the product quality , is the core of product competitiveness.

The ISO 9241-11 International standard defines usability as the effectiveness (effectiveness), efficiency (efficiency), and user subjective satisfaction (satisfaction) of a product for a particular user for a specific purpose in a particular use environment. which

• Effectiveness-the correct and complete degree to which a user accomplishes a specific task and achieves a specific goal;
• Efficiency-the ratio of the correct and complete degree of completion of the user's tasks to the resources used (such as time);
• Satisfaction-the subjective satisfaction and acceptance of the user in the process of using the product.

Usability Engineering (Usability Engineering) is an advanced development methodology for interactive IT products/systems, including a complete set of engineering processes, methodologies, tools, and international standards that apply to all stages of the product lifecycle, The core is the user-centric design methodology (user-centered DESIGN-UCD), emphasizing the user-centric development, can effectively evaluate and improve product availability quality, make up for the general development method can not guarantee the availability of quality deficiencies, since the 90 's began in the United States, Europe, Japan, India and other countries are widely used in IT industry.

uxd/ued (User experience design)--users experience

"User Experience", UX refers to the application of software and aesthetic value, is based on the user-oriented view as the cornerstone of the experience. It is composed of the following four main factors:

1. Impressions (Sensory impact)
2. Functionality of
3. Use of
4. Content

These factors are interrelated and indivisible to form the correct user experience. These factors are also a key factor in the success of a software. The "impression" can also be attributed to the software to create a "brand" effect. Uxd refers to some of the column designs that surround UX.
