10 Basic Interaction Design Principles to Boost the UI/UX Design

Interaction design is all about creating a great user experience. That’s why most UI disciplines require an understanding and hands-on experience of basic design principles. Interaction designers strive to create meaningful relationships between people, and the products and services they use. This may include computers, mobile devices, gadgets, appliances, and more. It is important to understand UX app design best practices while developing complex web and mobile applications. These are the key elements that product designers should not neglect while creating an interface for the user.

The information will be useful for both project owners and designers themselves. The UX designer’s hourly rate will directly depend on how deep the understanding of UI and UX Interaction Design is. Therefore, any developer should strive to improve.

Follow the generally accepted rules

Most people are creatures of habit. Once we learn how to use a piece of technology, we tend to stick with that same method of operation, even if there may be a better way to do things. This is especially true when it comes to computer interfaces. We expect buttons to perform certain functions, and when they don’t, it can be frustrating. This is why it’s so important for designers to create interfaces that are easy to understand and use. If a button doesn’t do what we expect it to, it’s probably not a good design.


Consistency is key in design, whether it be in terminology, layout, or interactions. By matching people’s expectations and keeping the design consistent throughout the process and between related applications, you are helping users learn more quickly. You can re-apply their prior experiences from one part of an application to another to maintain consistency throughout the design. Design consistency is also an aid to intuitive interfaces.

Bonus – you can use the inconsistencies to indicate to users where things might not work the way they expect. Breaking consistency is similar to knowing when to be unconventional. Ultimately, by being consistent in your design, you are making life easier for your users.

Functional minimalism

With so many options and features, it can be hard to know what you need and what is just superfluous bells and whistles. As Albert Einstein famously said, “Everything should be made as simple as possible, but no simpler.” In other words, the range of possible actions should be no more than necessary. This principle can be applied to everything from fashion to product design. When it comes to your wardrobe, for example, you don’t need a closet full of clothes; a few well-chosen basics will suffice. The same is true of technology. Too many features can detract from the primary function and reduce usability by overwhelming the user with choices. The key is to find the perfect balance between simplicity and functionality. By avoiding unnecessary features and functions, breaking complex tasks into manageable sub-tasks, and limiting functions rather than the user experience, you can achieve the Zen of functional minimalism.

Use simple words

Most people are not designers or developers, and as a result, they do not always understand the design concept or development process. However, this does not mean that users are not smart. Many users are very busy and need products that are easy to use and understand. Therefore, it is important to optimize some functions for middle-class users. This includes making sure that the language and text of the product are easy to understand and close to the user’s thoughts. By doing this, we can make sure that users have a positive experience with our product.

Don’t make the user think

Designing an effective user interface requires a deep understanding of cognitive psychology and how people process information. One of the key concepts in cognition is known as the “cognitive load,” which refers to the amount of mental effort required to complete a task. When designing an interface, it is important to minimize the cognitive load for users so that they can focus on the task at hand.


User engagement is a measure of how positive a user’s experience is with your product. An engaging experience is not only enjoyable but also easier and more productive. Engagement is subjective to the system. That is, your design must engage with the desired audience. For instance, what appeals to teenagers might be irrelevant to their grandparents.

Apart from aligning your design for the appropriate audience, achieving and creating control is the key. The interaction design principles state that users should always feel like they’re in control of the experience. They must constantly experience a sense of achievement through positive feedback/results or feel like they’ve created something.


Even though simple interfaces may require a certain amount of experience to learn, learnability makes interaction intuitive. People tend to interact with an interface similar to other interfaces. This is the reason why we must understand the process of interaction design thoroughly and the importance of design patterns and consistency.

Intuitive interface design allows users to learn to use the interface without much effort and gives them a sense of achievement when they can do so. In other words, users should be able to learn to use the interface in the first attempt and should not face issues using it again. An important interaction design principle is inducing the ability to learn to use the interface easily.

Of course, engaging interfaces also allow users to easily learn and remember the interactions they need to use within the given context. That said, an interface that is both intuitive and engaging provides users with the best possible experience and is likely to lead to higher satisfaction rates. Therefore, inducing learnability should be one of the main goals of any interaction designer

Error detection and prevention

All of us have experienced the frustration of trying to complete a task on a website or app only to find that we keep making mistakes. It’s even more frustrating when we can’t figure out how to fix the problem and have to start all over again. As designers, one of our primary goals should be to design interfaces that prevent users from making errors in the first place. There are several techniques we can use to achieve this, such as disabling functions that aren’t relevant to the user, using appropriate controls to constrain inputs, providing clear instructions and preemptive help, and as a last resort, providing clear warning messages.


Affordance refers to the quality of an object that allows an individual to act. The point is – users should get a clue about how to use an object through its physical appearance. While designing user interfaces, you can achieve affordance either by simulating ‘physical world’ affordances (e.g. buttons or switches) or by keeping consistency with web standards and interface design elements (e.g. underlined links or default button styles).

Encourage Feedback

When we interact with machines, we are essentially engaged in a process of information transmission. We send out information – through our actions, words, or thoughts – and receive information back from the machine. This interaction only works effectively if there is timely and effective feedback and explanation from the machine. And also allow users to connect with a live person. Then analyze the hits, and you may be able to find problems in your design.

Following the basic Interaction Design Principles will help improve the user experience, which will have a positive impact on conversion. This will positively affect the overall user experience and experience of your site or application.
