User experience design

User experience design is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand User experience design rather than just read about it. In short: User experience design (UX design, UXD, UED, or XD), upon which is the centralized requirements for "User Experience Design Research" (also known as UX Design Research), defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a user centered design approach because it considers the user's experience when using a product or platform.

Key takeaways

  • User experience design belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect User experience design to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of User experience design from memory before moving on to harder problems.

Reference excerpt

User experience design (UX design, UXD, UED, or XD), upon which is the centralized requirements for "User Experience Design Research" (also known as UX Design Research), defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a user centered design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions, for which is known as UX Design Research. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), and encompasses all design aspects and design stages that are around a customer's experience.

History User experience design is a conceptual design discipline rooted in human factors and ergonomics. This field since the late 1940s has focused on the interaction between human users, machines, and contextual environments to design systems that address the user's experience. User experience became a positive insight for designers in the early 1990s with the proliferation of workplace computers. Don Norman, a professor and researcher in design, usability, and cognitive science, coined the term "user experience", and brought it to a wider audience that is inside our modernized society.

I invented the term because I thought human interface and usability were too narrow. I wanted to cover all aspects of the person's experience with the system including industrial design graphics, the interface, the physical interaction and the manual. Since then the term has spread widely, so much so that it is starting to lose its meaning.

Elements

Research

User experience design draws from design approaches like human-computer interaction and user-centered design. It includes elements from similar disciplines like interaction design, visual design, information architecture, user research, and others. Another portion of the research is understanding the end-user and the purpose of the application. Though this might seem clear to the designer, stepping back and empathizing with the user will yield the best results. It helps to identify and prove or disprove assumptions, find commonalities across target audience members, and recognize their needs, goals, and mental models.

Visual design Visual design, also commonly known as graphic design, user interface design, communication design, and visual communication, represents the aesthetics or look and feel of the front end of any user interface. Graphic treatment of interface elements is often perceived as the visual design. The purpose of visual design is to use visual elements like colors, images, and symbols to convey a message to its audience. Fundamentals of Gestalt psychology and visual perception give a cognitive perspective on how to create effective visual communication.

Information architecture

Information architecture is the art and science of structuring and organizing the information in products and services to support usability and findability. In the context of information architecture, information is separate from both knowledge and data, and lies nebulously between them. It is information about objects. The objects can range from websites, to software applications, to images et al. It is also concerned with metadata, or data used to describe and represent content objects such as documents, people, process, and organizations. Information architecture also encompasses how the pages and navigation are structured.

Interaction design

Interaction design is an essential component of user experience (UX) design, that focuses on the interaction between users and products. The primary goal of interaction design is to create a product that produces an efficient and delightful end-user experience by enabling users to achieve their objectives in the best way possible. The growing emphasis on user-centered design and the strong focus on enhancing user experience have made interaction designers essential in shaping products that align with user expectations and adhere to the latest UI patterns and components. In the last few years, the role of interaction designer has shifted from being just focused on specifying UI components and communicating them to the engineers to a situation in which designers have more freedom to design contextual interfaces based on helping meet the user's needs. Therefore, User Experience Design evolved into a multidisciplinary design branch that involves multiple technical aspects from motion graphics design, animation. programming to even service design.

Usability

Usability is the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use. Usability is attached to all tools used by humans and is extended to both digital and non-digital devices. Thus, it is a subset of user experience but not wholly contained. The section of usability that intersects with user experience design is related to humans' ability to use a system or application. Good usability is essential to positive user experience but does not alone guarantee it.

Accessibility

Accessibility of a system describes its ease of reach, use, and understanding. In terms of user experience design, it can also be related to the overall comprehensibility of the information and features. It helps shorten the learning curve associated with the system. Accessibility in many contexts can be related to the ease of use for people with disabilities and comes under usability. In addition, accessible design is the concept of services, products, or facilities in which designers should accommodate and consider for the needs of people with disabilities. The Web Content Accessibility Guidelines (WCAG) state that all content must adhere to the four main principles of POUR: Perceivable, Operable, Understandable, and Robust.

Worked examples

Example 1 — a first encounter with User experience design

Start with the simplest possible case. Write down what User experience design claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to User experience design before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about User experience design ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of User experience design

In research
User experience design appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses User experience design in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
User experience design is common in secondary-school and first-year university syllabi. It links to neighbouring topics Design, Human–computer interaction, Software development process, so understanding it makes those chapters shorter.
In everyday life
Look for User experience design outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
