What is Interaction Design?

Design area helps to optimize resources and interface of digital projects

A focus on user experience is the foundation of any digital application. The growth brought different forms and areas to enhance the construction of new products and applications. 

Among these concepts is the interaction design. Here we will explain how this area of design works and how it is useful for the development of applications with good usability and interactivity in a project. 

Interaction design: how does this area of design work? 

Interaction design, also known as IxD, is an area of IT (information technology) and design, which seeks to study, plan and apply interactivity in physical and digital systems. The objective is to improve the relationship between product and user. 

In a simpler way, the intention of interaction design is to make users have contact with applications that are being designed. In this way, interaction design seeks ways to promote this interaction to optimize final projects.

What are the main goals of interaction design? 

The main objective of interaction design is to promote user contact with digital products in a simple and functional way. With this, the IxD professional looks for ways to predict the user's interaction with the project he is developing. 

In this way, the project is developed for the users and not for those who finance the project. Users become clients of the project and interaction design takes care of several competencies, check them out below:


Usability seeks to design applications where the user finds it easy to interact with a system. So the easier it is, the better. This favors the fluidity of navigation. And for that, designers use tools like prototypes and mockups for their projects. 


The product must be readable by all users. This indicates that an application needs to be concerned with the ease of understanding and interpretation of a product, which is what we call intuitiveness. 


Offering functionality is essential for any application. But these functionalities need to be useful, they need to deliver the interaction and fulfill what the feature promises.


Design aesthetics are part of readability, but it goes beyond beauty as form. In this way, a digital project needs to have a visually well-formatted and readable aesthetic.


The interaction designer needs to master several programming languages, especially front-end languages. This is the best way to guarantee the other pillars of interaction design, developing projects that deliver everything the application promises. 


What are the main benefits of interaction design? 

The main benefits of interaction design are the ease of delivering a design that is visually beautiful, easy to use, has useful features, and is effective at what it is dedicated to doing. 

Using interaction design helps to optimize communication between key design factors like interface, usability and product idea. Through this, it is possible to improve the development with the active participation of potential users. 

Having a team with a professional focused on IxD is essential for companies looking to develop website and mobile application projects. Interaction design shows how the IT area is essential in software and digital product creation projects. 

The trend is for interaction design to grow in the area of marketing and sales, as the interaction with users opens up space to reinforce innovative ideas and solutions.

As we noted in the article, having an interaction designer on the IT team is key to the success of digital projects. The quality of a project increases when the interaction is used to improve the approach, resources, and efficiency of the application.
