Once upon a time, websites and web applications were used to occupy some hard-coded, never-changing HTML scripts. But the thing is, those days are long gone. Now, as a UI designer, you can make this transition from data-only web app design to user-centric smart UI design in a very welcoming way. For that, you need to know the user interface design principles for web applications and how to adopt them as a designer. And this article is all about this specific concern (ui design principles). Got some minutes to check them out? Let’s go-

7 Important Interaction Design Principles

Principle 1: User-centric Design

The number one rule of web interface design is to keep users in mind. Before that, you must know the target users of the web application you are working on. The first rule of web interface design is to prioritize the user. Therefore, you must be well acquainted with the targeted users of the web application you are working on.

User centric Design

Once you're done with your research, put yourself in the users' shoes and re-consider the design process. One fun fact about users is that- they don't read, they just scan until they find the correct information they are looking for.

Also, web UI designers have to be aware of the operating habits, abilities, needs, and interactive methods of the users. Indeed, a particular product can not meet all of the user's needs. But it should be in the best manner that suits the majority of their demands.

Principle 2: Kiss (Keep It Simple and Stupid)

The title might seem attractive. But KISS is one of the primary UI principles designers must abide by. The manner of executing the KISS theory is to put users in control. When the users' can control the web application they are interacting with, that's a limitless possibility.

But users are not web designers themselves. You have to shift the control into users' hands in the simplest way possible. So, reduce the burdens on the users and keep the entire operation simple and stupid.

Consistency in Interactive User Interface Design

Principle 3: Stay Consistent

Let us clear out that being consistent in the placement of the features is essential for a web application. This is not for a particular product segment but the entire product. As an example, you are not supposed to keep the menu on the top of one page and at the bottom of another. Also, don't rearrange items of a particular element everything reloads. Try to develop an intuitive connection with the users. And let them develop a consistent idea of what parts of the application contain information or icons.

The question of consistency is also involved with font and typography. Don't involve different fonts on different pages. Also, don't go for swapping body/header/footer fonts from page to page.

Principle 4: Clarity is The Key

Some of you might think this two are the same; that's what their name suggests. But hey! they are not the same at all. We will tell you why- Clarity is associated with the application's way of informing the users about what to do at all times. This process might also involve UC design, but executing this formula is imperative.

The reason why minimalistic or brutalist web design has become so popular is its Clarity of it. With such a web application, the users will not be confused about what purpose a particular product segment serves. Having a little(or no) clutter is the key here.

Here are a few examples of clarity in a web application,

  • Move from one step to another on a completely different page.
  • Don't let the users scroll down for a long time to complete one process.
  • Let the users know where they are standing in the process.
  • Every dot of a mobile screen is a premium. Treat it as it’s supposed to be.

Principle 5: Keep the System Communicative

There are simply two interactions in a web-based application- one-sided and both-sided. In the second kind, users will interact with the system. They will upload items, download items, provide inputs and receive outputs.

Throughout this way of interaction, keep your system interactive. It will inform the users about what's going on in the system. Here are a few examples to keep on your to-do list-

  • When a button is pressed, provide an indication that it has been pressed.
  • When you have files uploaded from the user's end, provide pop-up showing progress. Also, provide the estimated remaining time to complete the process.
  • Whenever users take action, provide some small acknowledgment.

Principle 6: Don’t Re-invent, Innovate

Whenever it's about designing, the design elements of brands are pretty much common in various platforms and the advice from our side is not to re-invent these elements but to innovate. In this way, your product won't make the users think about how to figure things out. Instead, they can open their creative windows through your developed tool.

An example of what we are saying is- to think about the placement of login access to a web application. The pattern and placement of it should be the same as what it is in most other applications. But what you can innovate here is, letting the users choose strong passwords, remember the last login IDs, etc. Overall, make a perfect balance between creativity and usability. Don't overlap or terminate any of them.

Principle 7: Maintain A Strong Visual Hierarchy

Visual hierarchy is a crucial element of a web application's user interface design. And it can be acquired by having a clear view of the visual elements of a screen. Once acquired, it would be able to distinguish the information consumed by the audience.

Here are some 101 rules of a perfect visual hierarchy-

  • Make the primary information bold and place it in the center position. This list includes items like navigation, title, logo, etc.
  • Don't bold just anything you have in your path. Remember, when everything is bold, nothing is bold at all.
  • Highlighting elements with stand-out colors is another crucial action. Highlight important information, such as the product price with a different color. But don't use more than 7 colors on a particular screen.

If we are honest, we would like to add dozens of more principles to this list. But as a starter course, this set of principles should be enough to explain the user interface design principles for web applications. See you in the next post! 

Frequently Asked Questions (FAQ)

What are the basic principles of user interface design?

The basic principles of ui design are clarity, consistency, feedback, efficiency, flexibility, and error prevention/recovery. These principles ensure that the UI is clear, consistent, provides feedback, is efficient, adaptable, and helps prevent and recover from errors, resulting in a user-friendly system or application.

What is the golden rule of user interface?

The golden rule of user interface (UI) design, also known as the "one-click rule," is the principle that users should be able to complete a task with just one click or action. This means that the UI should be designed to minimize the number of clicks or steps required to complete a task, making it easy and efficient for users to achieve their goals. Following the golden rule of UI design can greatly enhance the user experience by reducing complexity and improving usability.

What are the 2 main components of user interface?

The two main components of a user interface (UI) are input and output. Input involves how users interact with the system, while output refers to how the system responds to user input and provides information or feedback. Both components are crucial for creating a usable UI.
