Having a mobile device is currently something as normal as having a wallet to carry our documents. Hence, the design and development of apps, especially interaction design, is one of the most demanded professions.

When we talk about this concept, we refer to the planning and development of all the elements that allow a smartphone user to interact with an application.

Interaction design: what is it

Interaction design is, without a doubt, one of the basic points of developing an app. It consists of designing the interactive services of an application, its systems, and its user environment, among other things. In short both the part that the user sees (the interface) and the part that the user does not see (the code).

The concept of interaction design emerged in the 80s of the last century when interactive user interfaces appeared. With the arrival of this concept, everything changed in the sector, and the design was focused on the user. It must be about finding a balance between everyone. As with any task, it must be done for a purpose.

This should also be related to the needs presented by the user. Therefore, it is important that, before beginning the design tasks, the developers are clear about what kind of users they are going to target their apps, their preferences, and their habits. Also, they must be clear about the characteristics and functions of the app must-have.

The basis is to know the app and how the public interacts with it.

In addition to talking to the target audience to find out their concerns and what they hope to find in an app, you also have to know how they interact with it. They even understand how they behave in certain situations, which can have a lot of influence on the design of the interaction. And therefore, in the final design of the app, since the interaction and how it will be carried out is basic for its planning.

To determine how user interaction with the app will be, there are several tools. The first is the user profile. It can be done bi-directionally: creating profiles of the people we are addressing from interviews with real people, or drawing up a profile of the app’s target audience with specific characteristics and finding them from it to study their form of being and its interaction with systems. These profiles will have all kinds of data, from the most general to more specific, such as hobbies, interests, and personal objectives.

The development of scenarios that must be worked with the users is another means to adequately plan the development of interaction. These scenarios are used to generate a simulation of the point or situation in which the user is going to have to interact with the future application to be developed. Once created and used, they should be stored together with the results obtained for use, when necessary, in design decision-making.
