Most hardware devices also include a user interface, though it is typically not as complex as a software interface. A common example of a hardware device with a user interface is a remote control. A typical TV remote has a numeric keypad, volume and channel buttons, mute and power buttons, an input selector, and other buttons that perform various functions. This set of buttons and the way they are laid out on the controller makes up the user interface. Other devices, such as digital cameras, audio mixing consoles, and stereo systems also have a user interface.
While user interfaces can be designed for either hardware of software, most are a combination of both. For example, to control a software program, you typically need to use a keyboard and mouse , which each have their own user interface. Likewise, to control a digital camera, you may need to navigate through the on-screen menus, which is a software interface.
Regardless of the application, the goal of a good user interface is to be user-friendly. After all, we all know how frustrating it can be to use a device that doesn't work the way we want it to. The definition of User Interface on this page is an original TechTerms. If you would like to reference this page or cite this definition, you can use the green citation links above. They include both input devices like keyboard, mouse, trackpad, microphone, touch screen, fingerprint scanner, e-pen and camera and output devices like monitors, speakers and printers.
Devices that interact with multiple senses are called "multimedia user interfaces". For example, everyday UI uses a combination of tactile input keyboard and mouse and a visual and auditory output monitor and speakers. User interface is important to meet user expectations and support the effective functionality of your site. A well-executed user interface facilitates effective interaction between the user and the program, app or machine through contrasting visuals, clean design and responsiveness.
When designing a UI for your site, it's important to consider the user's expectations in terms of accessibility, visual aesthetic and ease of use. An optimal mix of effective visuals and efficient responsiveness will improve your site's conversion rates, as it anticipates the needs of the user and then satisfies those needs. More specifically, here are the most important overarching elements of a great UI:. User interface and user experience are related and equally important to the execution of a project, but the specifics differ.
Mainly, UI is designed around the intended look and feel of the site, app or program while UX spans the entire process of conceptualization, development and delivery. Additionally, UX can be referenced in relation to nearly any product, while UI can only pertain to digital products. The main differences between UX and UI are:. Designing a user experience begins by identifying the pain points of the target users and figuring out how to meet the needs of said users.
This includes details such as logical flows or steps to take to reach a goal. Once the interface is programmed to be useful, the prototype is sent to a user interface designer, where the processes are made visually appealing.
An ideal UI design should be based on the UX. It should have an attractive, unique appearance; a logical structure; and be easy for users to understand. It's trickier than it sounds. Even after the UI design is perfected, there will inevitably be a lot of debugging and fine-tuning involved once it goes live.
Follow these tips to create an effective user interface:. Making sure there is simplicity and sufficient contrast between text and background colors makes reading much easier. A website should always be adaptable to the screen it's being viewed on, whether it's a 7-inch mobile phone or a inch TV. Build exploration into the project's lead time to give yourself a chance to discover new elements of design that can make your end product exceptionally unique and pleasurable to use.
Pick a design and stick with it throughout the project. Each page of the site should be laid out the same way to avoid any confusion or frustration in the user's experience. The interface should be conducive to an overall experience that is pleasant, easy and informative.
It can be easy to let the overall goal get lost in the minutiae of the design process but what you're designing is for the user and therefore should be user-focused. Your user should be able to identify your brand on every page of your site and new users should be able to recognize your brand upon their first visit. Pay attention to the ease of readability through the layout. For example, keep text edge-aligned, keep a limited color palette you want it to be colorful and eye-catching but not overwhelming and blinding , choose a font family that's easy to read and an optimal size.
Performing tasks should require minimal effort on the user's part and each page should serve one main function. This can include display screens, keyboards, a mouse, and the appearance of a desktop. User interfaces enable users to effectively control the computer or device they are interacting with. A successful user interface should be intuitive, efficient, and user-friendly.

User interface elements are the parts we use to build interactive websites or apps. They provide touchpoints for the user as they navigate their way around; from buttons to scrollbars, to menu items and checkboxes. Input controls allow users to input information into the system.
Navigational components help users move around a product or website. Common navigational components include tab bars on an iOS device and a hamburger menu on an Android. Informational components share information with users. This includes notifications, progress bars, message boxes, and pop-up windows.
Containers hold related content together, such as accordions. To find out more, read our ultimate glossary of the 32 user interface elements for UI designers! Never before have UI designers had such a diverse array of tools at their disposal. With software becoming increasingly intuitive, built-in UI components allow UI designers to take advantage of pre-made design decisions and create layouts in a fraction of the time. Sketch uses a combination of artboards and vector design shapes to enable designers to create hi-fi interfaces and prototypes on a pixel-based canvas.
This also helps to keep your interfaces consistent. If you decide to go with this tool, here are five common mistakes to avoid when learning Sketch as a UI designer.
Still in its early release, InVision Studio allows designers to create high-quality interactive interfaces, custom animations , and transitions. The slog of creating numerous artboards for multiple devices will also become a thing of the past, as responsive design can be achieved within a single artboard.
Adobe XD offers the best environment for digital projects under the Adobe Creative Cloud collection of design tools. You can draw, reuse, and remix vector and build artwork to create anything from screen layouts to interactive prototypes, all in the same app. To learn more about UI design tools, check out our take on the 7 essential tools every budding UI designer should know , and these 12 tools for mobile app design.
When an interface is well designed, it becomes a seamless experience unnoticeable to the user. But a poorly designed interface means users cannot complete their task flow. Cognitive load refers to the amount of mental processing power a user needs to use a product. In the face of an information overload, users will miss important details, get overwhelmed, or even abandon the website or app altogether.
To keep cognitive load to a minimum, avoid old links, irrelevant images, and meaningless text. Instead, apply general principles of content organization such as grouping related items, bullet points, clear headings, and obvious call to actions. Consistency in a user interface allows the user to transfer existing knowledge to new tasks and master new aspects faster.
It also means that users can avoid wasting the time it takes to understand the differences in certain controls or commands, and instead focus on solving the problem. All in all, consistency makes the interface design recognizable and predictable. Keeping the interface clear and straightforward will instill confidence in the user, which will motivate them to continue interacting with the interface. Users like to feel in control of themselves and their environment.
Thoughtless software takes away that comfort by forcing people into unplanned interactions, confusing pathways, and surprising outcomes.
