User interface (UI) design or user interface engineering is the design of user interfaces for machines and software, such as computers, home appliances, mobile devices, and other electronic devices, with the focus on maximizing usability and the user experience. In computer or software design, user interface (UI) design primarily focuses on information architecture. It is the process of building interfaces that clearly communicates to the user what’s important. UI design refers to graphical user interfaces and other forms of interface design. The goal of user interface design is to make the user’s interaction as simple and efficient as possible, in terms of accomplishing user goals (user-centered design).
User interfaces are the points of interaction between users and designs. There are three types:
- Graphical user interfaces (GUIs) – Users interact with visual representations on a computer’s screen. The desktop is an example of a GUI.
- Interfaces controlled through voice – Users interact with these through their voices. Most smart assistants, such as Siri on smartphones or Alexa on Amazon devices, use voice control.
- Interactive interfaces utilizing gestures- Users interact with 3D design environments through their bodies, e.g., in virtual reality (VR) games.
Interface design is involved in a wide range of projects, from computer systems, to cars, to commercial planes; all of these projects involve much of the same basic human interactions yet also require some unique skills and knowledge. As a result, designers tend to specialize in certain types of projects and have skills centered on their expertise, whether it is software design, user research, web design, or industrial design.
Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design and typography are utilized to support its usability, influencing how the user performs certain interactions and improving the aesthetic appeal of the design; design aesthetics may enhance or detract from the ability of users to use the functions of the interface. The design process must balance technical functionality and visual elements (e.g., mental model) to create a system that is not only operational but also usable and adaptable to changing user needs.
Compared to UX design, UI design is more about the surface and overall look of a design. User interface design is a craft in which designers, perform an important function in creating the user experience. It is a functional design interface bridging the gap between users and the product in an attractive and intuitive way. UI design should keep users informed about what is happening, giving appropriate feedback in a timely manner. The visual look and feel of UI design sets the tone for the user experience. On the other hand, the term UX design refers to the entire process of creating a user experience.
It’s important to distinguish the total user experience from the user interface (UI), even though the UI is obviously an extremely important part of the design. As an example, consider a website with movie reviews. Even if the UI for finding a film is perfect, the UX will be poor for a user who wants information about a small independent release if the underlying database only contains movies from the major studios.
User experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a digital product or website. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. 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), which encompasses all aspects and stages of a customer’s experience and interaction with a company.
The field of user experience design is a conceptual design discipline and has its roots in human factors and ergonomics, a field that, since the late 1940s, has focused on the interaction between human users, machines, and the contextual environments to design systems that address the user’s experience. With the proliferation of workplace computers in the early 1990s, user experience started to become a positive insight for designers. Donald Norman, a professor and researcher in design, usability, and cognitive science, coined the term “user experience,” and brought it to a wider audience.
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.
— Donald Norman
There is a debate occurring in the experience design community regarding its focus, provoked in part by design scholar and practitioner, Don Norman. Norman claims that when designers describe people only as customers, consumers, and users, designers risk diminishing their ability to do good design.
User experience design draws from design approaches like human-computer interaction and user-centered design, and includes elements from similar disciplines like interaction design, visual design, information architecture, user research, and others.
The second part 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 my assumptions, find commonalities across target audience members, and recognize their needs, goals, and mental models.
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.
Responsive web design (RWD) or responsive design is an approach to web design that aims to make web pages render well on a variety of devices and window or screen sizes from minimum to maximum display size to ensure usability and satisfaction.
A responsive design adapts the web-page layout to the viewing environment by using techniques such as fluid proportion-based grids, flexible images, and CSS3 media queries, an extension of the @media rule, in the following ways:
- The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points.
- Flexible images are also sized in relative units, so as to prevent them from displaying outside their containing element.
- Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on, e.g. width of the rendering surface (browser window width or physical display size).
- Responsive layouts automatically adjust and adapt to any device screen size, whether it is a desktop, a laptop, a tablet, or a mobile phone.
Responsive web design became more important as users of mobile devices came to account for the majority of website visitors. In 2015, for instance, Google announced Mobilegeddon and started to boost the page ranking of mobile-friendly sites when searching from a mobile device.
Responsive web design is an example of user interface plasticity.
Mobile-first design and progressive enhancement are related concepts that predate RWD. Browsers of basic mobile phones do not understand JavaScript or media queries, so a recommended practice was to create a basic web site and enhance it for smartphones and personal computers, rather than rely on graceful degradation to make a complex, image-heavy site work on mobile phones.
Luke Wroblewski has summarized some of the RWD and mobile design challenges and created a catalog of multi-device layout patterns. He suggested that, compared with a simple HWD approach, device experience or RESS (responsive web design with server-side components) approaches can provide a user experience that is better optimized for mobile devices. Server-side CSS generator implementation of style sheet languages like Sass can be part of such an approach. Google has recommended responsive design for smartphone websites over other approaches.
Although many publishers have implemented responsive designs, one challenge for RWD adoption was that some banner advertisements and videos were not fluid. However, search advertising and (banner) display advertising came to support specific device platform targeting and different advertisement size formats for desktop, smartphone, and basic mobile devices. Different landing page URLs have been used for different platforms, or Ajax has been used to display different advertisement variants on a page. CSS tables permitted hybrid fixed and fluid layouts.
There have been many ways of validating and testing RWD designs, ranging from mobile site validators and mobile emulators to simultaneous testing tools like Adobe Edge Inspect. The Chrome, Firefox and Safari browsers and developer tools have offered responsive design viewport resizing tools, as do third parties.
The first site to feature a layout that adapts to browser viewport width was Audi.com launched in late 2001, created by a team at razorfish consisting of Jürgen Spangl and Jim Kalbach (information architecture), Ken Olling (design), and Jan Hoffmann (interface development). Limited browser capabilities meant that for Internet Explorer, the layout could adapt dynamically in the browser whereas, for Netscape, the page had to be reloaded from the server when resized.
Cameron Adams created a demonstration in 2004. By 2008, a number of related terms such as “flexible”, “liquid”, “fluid”, and “elastic” were being used to describe layouts. CSS3 media queries were almost ready for prime time in late 2008/early 2009. Ethan Marcotte coined the term responsive web design—and defined it to mean fluid grid / flexible images / media queries—in a May 2010 article in A List Apart. He described the theory and practice of responsive web design in his brief 2011 book titled Responsive Web Design. Responsive design was listed as #2 in Top Web Design Trends for 2012 by .net magazine after progressive enhancement at #1.
Mashable called 2013 the Year of Responsive Web Design.
