What is meant by user interface design?

User interface design refers to the process of building the visual scheme for the interface of electronic applications and websites and includes creating a set of elements that the user interacts with such as buttons, colors, icons, icons, and navigation menus.

Difference between user experience design and user interface design

UX design relates to everything related to the feeling, sensation, and perception of a person when trying a particular system or application. It is concerned with the user's preferences and their physical and psychological reactions and aims to produce systems that are easy to use for all groups and to study what suits them. As for the user interface, it is the aesthetic image that appears to users, allows them to interact with the system, and facilitates their access to the website or application.

For example, if you have an online application that has a great interface, attractive appearance, and colors that match your branding, then you have a good UI design. As for the speed of loading its pages, easy access to the conversion button, and making purchases smoothly, this is what is called the user experience UX.

Types of user interfaces

User interfaces are divided into three main types:

GUI graphical user interfaces

Graphical User Interfaces (GUIs) are interfaced with which the user interacts by clicking on graphic elements such as pictures, symbols, and icons, to convey information and perform certain tasks. It is characterized by ease of use, as it contains clear and understandable forms. For example, a design might contain a recycle bin icon to indicate deletion, and files could be copied by dragging and dropping.

CLI command line interface

The Command Line Interface appeared before graphical user interfaces and is called the command line interface, because it relies on writing text commands and entering them using the keyboard and not the mouse, so that the result appears in the form of text as well, and one of the most prominent examples is the MS-DOS operating system.


These interfaces have revolutionized the world of technology, especially since they allow people to interact with computers, mobile devices, or any other device via voice, thus dispensing with keyboards and touch screens, and only addressing devices with their voice, such as Google Assistant, Siri, and MS Cortana systems.

Fundamentals of user interface design

There are basics that designers must consider when creating user interfaces; To obtain greater chances of success for the design on the one hand, and for ease of programming on the other hand, namely:

  • Ease of navigation: When designing the user interface, one should consider the ease of navigation between program or system interfaces, and not distract the customer, especially if the site or application is large and complex. The user must be given a clear picture of the application, where it is currently located, where to go, and which button to press.
  • Considering the undo option: It is necessary to add an option to go back, to allow the user to undo an action taken by mistake or perhaps to explore, and this gives him a sense of security when navigating between the pages and interfaces of the program.
  • Take into account the clarity of the status of progress: Good user interface design takes into account the amount and amount of achievement that the user has implemented. This gives him a positive feeling of progress and knowledge of the steps to follow next.
  • User control over the interface: Controlling the user interface is one of the most important basics. Because it gives the customer the freedom to change the background, colors, and font size so that he does not feel restricted in use.
  • Taking into account individual differences: ease of dealing with all groups and ages with the interface of the program.

The process of designing the user interface goes through a set of necessary stages, the most important of which are:

1. Determine the design objective and requirements

Determining the design goal and its requirements is the first stage in user interface design. The user interface cannot be designed without knowing its basic purpose, understanding the problem that the design addresses, and what it presents to users. Therefore, it is necessary to create a list that includes the needs of users from the site whose interface is to be designed, identify all the requirements and functions that it performs to serve customers, and then identify the design elements that achieve the goal of these requirements, in addition to determining performance indicators to measure the success of the design later.

2. Conduct market and competitor research

Studying the target market is an essential pillar for the success of any project, as the necessary research must be conducted to study competitors and view their websites and electronic applications. To analyze them and find out their strengths and weaknesses. It is important to study the target audience and conduct in-depth interviews with a sample of customers, to find out their needs for the system and their preferences in user interface design.

3. Create an organization chart for the design

Once you've done your market research, you have an idea of ​​the user interface you want for your site. Therefore, the number of website pages should be determined and their functions understood; To begin, prepare a detailed diagram that explains the steps of the system, including the site pages, interfaces, and main elements.

At this stage, the outline of each page must be clarified, with a hierarchical and visual drawing of the screens, highlighting all the details and defining the relationship of the pages to each other. There is no objection to drawing the design on paper or using assistive technology tools.

4. Create a UI design template

It's time to actually design the user interface, and you start designing the visual elements like images, static and animations, colors, input elements, fonts, icons, etc. Then the user interface designer employs these elements according to the structure of each page and takes advantage of the research conducted to design a distinct user interface.

  • Design requirements: The cost of user interface design varies according to the client's needs, the number of pages and interfaces to be designed, and the tasks to be performed.
  • Design complexities: If the UI design is complex and includes many elements and multiple commands, it will be more expensive than a simple design.

9 tips for a professional user interface design

Some many tips and practices can be considered to create a professional and distinctive user interface design that is consistent with your brand, including:

  1. Good preparation: Try to collect everything you need in one place, by which we mean choosing fonts, icons, colors, and images, and put them in one place to serve as an integrated library for your reference.

  4. Ease of access: Make sure to divide the phone screen into an easy-to-reach area close to the user's finger, an accessible area in the middle of the phone screen, and a difficult-to-reach area at the top of the phone screen. Take advantage of this in arranging important buttons and icons.
  5. White spaces: Pay attention to increasing white spaces in the design of the user interface, because it attracts the audience and increases their sense of comfort and enjoyment of an enjoyable browsing experience.
  6. Font quality: Fonts should be well studied and their types should be known, and the appropriate ones should be used, so that they can be read clearly in the design of the user interface. It is preferable to use one family of fonts with different weights.
  7. Design Consistency: Make the design consistent, and avoid long scrolling in the interfaces so that the user does not feel bored before reaching his goal.
  8. The proximity of elements: If you are looking for an optimal user experience, design elements, and icons should be rounded, avoiding scattering and spacing.
  9. Simplicity and clarity: The design should be simple and make it clear to the customer where they stand now, and what they should do in the next step.

Finally, it's indisputable that UI design is a must-have for the success of any digital product today, and it's worth it to achieve your marketing goals. Creating a website or application without caring about the user interface; Like someone who starts building a house without planning, and most likely will be doomed to failure.
