User study to validate a new product interface

What was the challenge or problem to solve?

The objective of this project is to know the perception and preference through a user study, regarding the interface present in a certain household appliance related to the cooking area.

In this way, it was possible to measure the acceptance of new interface designs that incorporate new functionalities, and to verify the acceptance of the same by the users.

The first phase of the study focused on the definition of the target of potential users to be addressed, and the study of the context of use of this appliance.

With a previous analysis of the product on which to carry out the session, we designed the approach of the testing dynamics according to the initial objectives set at the beginning; thus defining a series of qualitative tools that, aimed at the potential user in question, provided us with the necessary feedback to validate the new concepts proposed and to know the future design strategy to be followed.

How was it addressed or what was the solution?

First of all, the strategic design team conducted an analysis of the specific target users we were targeting, in order to learn about their habits and current use of the appliance to be analyzed, as well as their perception of the current interface.

Once we had a more in-depth knowledge of the current use and having been able to get to know how users interact daily with this product, we proceeded to test with them the new product concepts among which new interface concepts were proposed in them with the help of high fidelity prototypes.

In this way we were able to obtain direct feedback by being able to see how users interacted with the new proposals, and to see first-hand how they used each of them.

Finally, this phase of the project concluded with the identification of real needs, the validation of the interface concepts designed, and the measurement of user interest in each of them.

All this allowed us to make better and more confident decisions about the next steps to be taken.


  • To know how users currently perform the tasks and their habits around the appliance within the cooking area.
  • Understand the needs that users may have in the process they currently follow.
  • Design different interface solutions that solve or alleviate the pains and reinforce the gains detected.
  • Investigate the possibility of developing different solutions at a technological level in relation to the functionalities of the possible interface.
  • To know the preferences, interest, and acceptance of the new concepts by the users.


  • Study of the habits and current perception of users with the current product.
  • Analysis of the needs, and identification of gains and pains of the users in relation to the appliance on which we are working.
  • Study of the technological feasibility in terms of adding new desired functionalities.
  • Design of different graphic solutions in which these pains are solved, and the new functionalities desired by the users are implemented.
  • Validation with users of the proposed concepts to detect their preferences.
