UI/UX
User Interface (UI) Principles
Let’s start with the fundamentals of user interface design. Constantine and Lockwood describe a collection of principles for improving the quality of your user interface design.
1.The structure principle
Your design should organize the user interface purposefully, in meaningful and useful ways based on clear, consistent models that are apparent and recognizable to users, putting related things together and separating unrelated things, differentiating dissimilar things and making similar things resemble one another. The structure principle is concerned with your overall user interface architecture.
Users want you to fill their needs.
- Use the most appropriate page layout. Consider the spatial relationship between items on the page and structure them according to their importance. The most important items should be easily accessible. Appropriate placement draws attention to the most relevant pieces of information and improves readability.
- Design strategically. You can manipulate user`s attention using colour, light, contrast, and texture.
2.The simplicity principle
Your design should make simple, common tasks simple to do, communicating clearly and simply in the user’s own language, and providing good shortcuts that are meaningfully related to longer procedures.
Users like to speak (and read) in their language.
- Use appropriate language.
All interfaces require copywriting. Provide clear labels for actions and keep your messages simple, not lengthy. Users will appreciate it because they like to communicate effectively. - Use font type setting to create hierarchy and clarity.
Don’t forget that people read 2 or 3 words at a time. Various sizes, fonts, and arrangement of the text will help to increase scanability, legibility and readability of your pages or screens.
3.The visibility principle
Your design should keep all needed options and materials for a given task visible without distracting the user with extraneous or redundant information. Good designs don’t overwhelm users with too many alternatives or confuse them with unneeded information.
Users don’t like surprises.
- Be consistent. Use mutual elements and create consistency of your UI. Users feel more comfortable and can operate quickly when they can find familiar elements and patterns. Besides, the interface should keep the same patterns across languages, layouts, elements, colours and fonts throughout the different pages or screens to help facilitate efficiency.
- Help your users to learn your product. The consistency of UI and using mutual patterns help your users learn easier. When they figure out how to use one part of the product they can apply these skills to other parts.
4.The feedback principle
Your design should keep users informed of actions or interpretations, changes of state or condition, and errors or exceptions that are relevant and of interest to the user through clear, concise, and unambiguous language familiar to users.
Users like being confident.
- Communicate with users when they to do something right.
Interface should always speak to users when their actions are not only wrong or misunderstood but also when they are right and help go forward. Users should be proud and feel confident. - Don’t be annoying.
Do you remember that the users’ research is the first step of user interface design? UI shouldn’t annoy your target audience.
5.The tolerance principle
Your design should be flexible and tolerant, reducing the cost of mistakes and misuse by allowing undoing and redoing, while also preventing errors wherever possible by tolerating varied inputs and sequences and by interpreting all reasonable actions reasonable.
Users don’t like making choices.
- Think well about defaults.
Users do not only like making choices but also do not like doing extra work. Using the UI forms where you might have an opportunity to have some fields pre-chosen or filled out can help users interact with your product and contribute to the business goals achievement. - Do not provide unnecessary options.
If you give your users, the opportunity to choose. Make sure all options are necessary and/or provide some business value.
6.The reuse principle
Your design should reuse internal and external components and behaviors, maintaining consistency with purpose rather than merely arbitrary consistency, thus reducing the need for users to rethink and remember.
Users don’t like being frightened.
- Make sure the system communicates with users and tells them what’s happening.
It isn’t good when a user doesn’t understand what is going on and how to go forward or back. Use various UI elements to show the status of the task and/or progress of some process. Display the error and notify how to eliminate it. - Always display the location and give the opportunity to go back.
Familiar UI elements and patterns that give the information of the user’s location and explain how to go back help reduce their frustration. Make sure users understand how to exactly navigate. - Use the “forgiveness” principle.
It’s good when the interface can prevent some of the user’s errors and gives the opportunity to cancel wrong actions. Give users features like confirmation/cancellation, save and edit later, display the tips (in some cases) etc.
A good user interface design leans on three perfectly balanced pillars: attractiveness, usability and high-level business performance.
Some of these principles are often neglected and we all face the examples of:
- Amazing looking but nearly impossible to use websites and mobile applications;
- Very complex and multi-component business applications that help provide high performance but doestn’t look that good.
User interface design is a very complicated thing that requires a lot of knowledge, experience and making researches. Following certain rules and main principles can make it easier. Remembering the goals to produce software products that are attractive and user-friendly.
