Visual Interface Designing For Ergonomic Applications



App designing has been one of the most critical domains in Computer Science, as users continue to value ergonomics, aesthetics, and simplicity of use. Designing interfaces for different users is complicated as different users have different preferences. For example, the younger generation usually likes darker themes, whereas elders prefer light and minimalist themes. So, how do we solve this problem? Luckily, some rules make our task more comfortable, and these rules are proven scientifically and help you with the design.

Visual design aims to improve a product's aesthetic quality and usability by using suitable images, typography, space, layout, and color. Visual design is about more than aesthetics. 


First, we start with the colors. Before picking one, we must know basic definitions.

Primary color: It is the color that is displayed most frequently across your app. It has to be chosen carefully considering the crowd which will be visiting the website. On the safer side, choose a light theme that matches the content on the website.

Secondary color: Having a secondary color is optional. It is used to accent your application. It is applied sparingly. 

Okay, so we know what the basic definitions are, now we choose a background (background of the app) and surface(surfaces consist of various ) colors.  

This figure shows a possible combination of colors that can be chosen. (on primary and on secondary colors are ones who are selected for writing on primary and secondary colors) . Error messages are generally displayed in red, success messages are shown in green and blue.

The colors chosen should be

  • Consistent- Colors must be consistently applied throughout the application and be compatible with the product it represents.
  • Distinct- Colors chosen should allow the user to distinguish between elements.
  • Intentional- Colors must convey meaning to the user, like red color for error gives danger and similarly, green color is for success.




This is where the actual design starts. It is a vast topic, and we will just cover the basics of layout for you to get started. 



  • Predictable-Use intuitive and predictable layouts with consistent UI regions and spatial organization.
  • Consistent-Layouts should be consistent in the use of grids, keylines, and padding.
  • Responsive-Layouts are adaptive, and they react to input from a user, a device, and screen elements.


For designing the layout, we must consider navigation ( how will the user navigate to different pages, the type of navigation to be used to make it intuitive for the user sp that he can understand the application easily.) Icon design and sizes are highly subjective and vast, so that we won't cover them here.




  • Lateral Navigation- Elements of the interface which are at the same level should be navigable using lateral navigation.


Lateral navigation can be achieved using tabs, lists, etc., as shown in the image.

  • Forward Navigation- Elements at a deeper level can be explored using forward navigation; for example, clicking a picture gives details about that, or clicking an icon redirects us to its page. 


Clicking on any list here will enlarge it and allow editing it this is how forward navigation works. It takes you a level deeper. It should only be used for the purpose mentioned above. 


  • Reverse navigation - used to go to the previous page or go back (hierarchically or chronologically). 



Apart from navigation, there are a few more things to consider.


  • Buttons / Clickable items- All the clickable things are generally given an elevated look to indicate that they are clickable. Button icons should show their function, and button colors should be applied carefully ( red button for the warning).
  • Pictures- Enlarging pictures when hovered on them would be a good addition. Inserting slide effects would also be awesome.
  • Minimalism- Try not to fill the interface with multiple items very close to each other, try to give a cleaner look, and putting many things on a single page would increase loading time (in the case of web applications)


Great! Folks, now you are ready to design applications that are user-friendly, good-looking, intuitive, and efficient.
