Everything a person interacts with while using a digital product, from the buttons they touch to the way information is communicated to them via color, font size, picture spacing, and layout, is referred to as user interface design. Strong UI design may result in a smooth and pleasant user experience in which people don’t even notice the design components. When done incorrectly, the UI may annoy and mislead consumers, leading to product abandonment.
Most UI designers adhere to a set of principles or guidelines that govern the software design process. Besides Ben Shneiderman’s “Eight Golden Rules of Interface Design,” Jakob Nielsen’s “Ten Usability Heuristics for UI Design,” and Bruce Tognazzini’s “First Principles of Interaction Design”, here are some of the recurrent principles commonly utilized by UI designers.
What is UI?
The term “user interface” refers to any technique or methods through which a product’s end-user interacts with or controls a product, software, or hardware device. A good user interface should make the interaction between the user and the product as seamless, easy, and pleasant as possible.
Most software applications these days are managed via a graphical interface, which allows users to virtually manipulate visual representations on a screen using a mouse or a keyboard. Hardware user interfaces often include a remote control or a joystick.
Why UI is important in software development?
It is obvious why user interface design is so essential once you grasp the user interface concept.
User interface design is one of the most important methods to attract visitors to your website and therefore progress toward better conversion rates. Your audience is captivated by UI design, which persuades them to remain on your site and take a closer look. People are more likely to become customers and refer your company to their friends and family members if they are personally affected and attracted to an excellent website.
You will not have a good online presence unless you have a user-friendly interface. Therefore, JSLancer would bring you the ultimate solution for your web that satisfies the needs and requirements of different subjects.
5 golden rules to succeed
Prioritize consistency and usability
This concept is really two distinct principles from Shneiderman’s list that overlap. From the design of prompts and menus to the overall look of the product, the design of a web page or app should be consistent.
Consistent action sequences should be required for all similar situations (for example, if a user is required to swipe to the next page in one instance, the swiping gesture should be used for all similar tasks). Moreover, consistent commands should be expected, and designs should be accessible and usable by as many people as possible, regardless of whether they are novice users or experienced users.
With experience working in the IT field, JSLancer has enough resources and abilities to provide insightful and smooth UI design. The design will be a combination of modern technologies and our knowledge of users’ behavior. Therefore, you will save more time and money when consulting with us to build UI design.
Offer informative and supportive message
At all times, the user should be aware of where they are and what is going on. Within a fair period of time, relevant, human-readable feedback should be provided for each activity. When completing a multi-page questionnaire, a nice example of this would be to signal to the user where they are in the process. A poor example is when an error message displays an error code rather than a human-readable and relevant message.
Make the interaction comfortable and clear
Make sure there is nothing on the website that may lead a user to mislead. When users take activities, provide useful feedback so that they know whether the activity was successful. For example, an app may recognize significant activities by altering the color scheme of a page or reacting with animation, while small actions may be acknowledged by simply checking off a data input box or graying out portions that have previously been completed.
The aim of this regulation is to provide consumers with a feeling of comfort and closure, letting them know they don’t need to think about contingency plans.
Don’t overwhelm users
Human attention is limited, and we can only keep around five things in our short-term memory at any one moment. As a result, interfaces should be kept as basic as feasible, with an appropriate information hierarchy and a preference for recognition over recall. Recognizing something is usually simpler than recalling anything because recognition includes detecting signals that assist us in reaching into our vast memory and enabling relevant knowledge to emerge. For example, we frequently perceive multiple choice questions on a test to be simpler than short answer questions since they just need us to identify the answer rather than remember it from memory.
Jakob Nielsen, a user advocate and one of the “world’s most influential designers,” was named one of the “world’s most influential designers” by Bloomberg Businessweek. He developed many usability techniques, including heuristic assessment. One of Nielsen’s 10 usability criteria for interface design is recognition over recall.
Designers should guarantee, in the same spirit as minimizing misunderstanding, that:
- The page’s design should not result in significant mistakes (for example, an online storage app should not include the “delete” button in a prominent position where it may be inadvertently clicked or touched), and
- If a mistake occurs, activities should be as reversible as feasible. The latter is especially important because easy reversal of actions reduces user anxiety, encourages exploration of unfamiliar options, and can save users time, particularly when the units of reversibility vary between a single action, a data entry task, and a complete group of actions.

UI design is a satisfying and creative profession that fosters the development of both hard and soft skills (research, concept creation, prototyping, and testing) (empathy, communication, collaboration).
It is also a crucial talent that may have a huge effect on businesses—good UI design can mean the difference between a product that is used by millions and one that fails to find an audience. It may also be the difference between having a strong brand and a devoted user base and being recognized for delivering unpleasant customer experiences. We hope that you understand some common principles to have a successful UI design.
