A user interface (UI), is a crucial component of many applications and software. Users depend on the interface to help them navigate and use an application, so developers consider the functionality and experience of a UI carefully during the design process. Understanding what a UI is can help you understand its importance and function, especially if you're interested in the technology industry. In this article, we explore what a UI is and why it's important, go over different types of UI, explain the differences of UI vs. user experience (UX) and offer some helpful tips on creating better UIs.

What is a user interface?

A user interface is the part of an application where an end-user interacts with a programme. The UI's purpose is to make an end-user's interactions with an application both intuitive and simple, which helps make the application more practical and efficient to use. UIs leverage a person's various senses of sight, touch and sound to create layers of interaction. You're using a UI when you type on a keyboard, use a mouse, touch a mobile device screen or use a speaker.

Types of UI

There are many types of UI, which serve different purposes, such as:

  • Form-based UI: Form-based interfaces depend on various forms to offer the user only limited choices on how to interact with an application. For example, a settings menu may help a user dictate their device's performance by providing various fields they can choose from.

  • Graphical UI: Graphical interfaces are a combination of interfaces that leverage user input to create a visual UI output. For example, when you type on a keyboard or click with a mouse, there's a subsequent response on the monitor.

  • Menu-drive interface: Menu-driven interfaces use a menu to help users navigate a website, software or application. For example, a website may have a drop-down menu that allows users to navigate to different pages within a site.

  • Touch interface: A touch UI is an interface that depends on physical touch. For example, there are many smartphones, tablets and monitors with touchscreen capabilities.

  • Voice interface: A voice UI allows users to interact with a program using only their voice. For example, if you use voice commands for a virtual assistant, you're interacting with the device's voice UI.

Why is a good UI important?

A good UI can be critical to the success of an application because it dictates how a user interacts with it and whether the program fulfils its primary functions. Users typically expect a UI to be easy to use and practical in design. For example, a drop-down menu may help a user navigate a site, but organising the buttons on the menu intuitively can make it even more functional.

For websites, a good UI can improve conversion rates, increase traffic and improve user engagement by making the site easier to use. Businesses can benefit from intuitive UIs through increased productivity and reduction of user errors. Applications that are difficult to use may alienate end-users who aren't able to identify UI features easily.

UI components

A good UI typically comprises the following elements:

Information architecture

Information architecture is the way you organise information within a website, software or application. This is crucial to the success of a UI because it organises information based on importance and sequential order for maximum efficiency. Developers depend on information architecture to help dictate how to build their UI and to gather feedback from users. For example, organising a website's different pages in sequential order to maximise retention.

Interactive design

A UI's purpose is to provide an interactive experience for end-users, so it's important to consider interactive design when developing a good UI. Developers typically design their UIs from the perspective of potential users to be more considerate of their potential needs or limitations. For example, developers may make a specific button on a keyboard serve as shortcut functions to reduce hand movements across a keyboard. Interactive design depends largely on the experience and skill of the developer and a strong understanding of what users of an application expect from their experience.

Visual design

The visual design of software, websites and other applications is also crucial to the overall user experience and success of the UI. Aesthetic value can keep users interested and make the process of navigating an application simpler. For example, optimising a website for mobile devices helps ensure that aesthetic components appear correctly on smartphones and tablets.

This can help the website feel more functional and practical for a user that can increase engagement. It's also important to consider potential limitations of users. For example, if you're designing an application that many older people may use, you can consider having larger text and buttons and providing more user guidance.

UI vs. UX

UI and user experience (UX) are two concepts that are critical to the development process. Here are some more key differences between these two:

  • Functionality vs. interaction: UX focuses heavily on the overall purpose and functionality of an application. UI focuses on the actual user interaction and how those interactions can affect the success of an application.

  • Experience vs. design: UX focuses on identifying the needs of the users through market research and beta testing, where a UI focuses on the overall design, including aesthetics, of the final product.

  • Administration vs. labour: The UX design process usually involves the management of a project discussing various ideas, while the UI design process focuses on the actual manual programming by technical professionals.

  • Concept vs. tangibility: Where a UX focuses more on the concept of a project and how it may function or interact with users, the UI process focuses on creating a tangible product for testing and application.

Tips for better UI

If you want to build a better user interface, here are some tips you can follow:

Use a wireframe to outline your software

Wireframes are simple, effective tools for outlining software and mobile applications. A wireframe can be a simple hand-drawn mockup of how you want an application's interface to look. This can serve as the blueprint for a design process, providing a preliminary guide for functionality and aesthetics. The sooner you can identify potential problems and strengths with a design, the more readily you can address them to enhance the design process. Consider using a wireframe for your next project, whether it's hand-drawn or you use a wireframe software.

Master aesthetic design

Aesthetic design is crucial to good user interaction with any software, application or website. For example, if a website's graphical elements, text and menus have matching colour schemes, good typography and spacing that match a brand's image, it can feel more consistent and professional. This may influence web traffic and user engagement, increasing site visitors to attract customers. Work on your aesthetic design skills by experimenting with how colours, shapes and spacing interact. You can also practise typography, which is how you arrange letters and words on a web page or programme.

Leverage user feedback

User feedback is one of the most important factors in improving a UI. User feedback can help developers identify the strengths and weaknesses in their designs to find areas they can improve. For example, if multiple users complain about a distracting font on your website, you can change it to a more appealing font. Users often appreciate when you listen to their feedback, which can also improve trust to increase customer loyalty. If users trust a company that designed a product with them in mind, they may be more willing to purchase the product.

Use what works

While it can be helpful to experiment with new concepts and designs, you can also use concepts and methods you're already familiar with and that have had success. For example, you may choose to use a programming language you're more familiar with rather than one commonly used for an application you're working on. When you run into any issues, you can consider researching if other developers have encountered similar issues and see if their solutions apply to your situation. This can be more efficient than trying to analyse and solve every problem encountered.

Understand target audience

It's crucial to understand the target audience of the application you're designing. Certain audiences may expect different features in a UI. If you're developing software for other developers, you may put extra care into functionality and minimising aesthetic features. Market research can help development teams better understand who they're designing for and what that audience may expect. You can also research competitors, such as any feedback their products may have received.
