One of the fundamental questions we asked ourselves immediately at opening the round of discussions was: Is there  a relationship between a visual device, for that matter, a mobile app, and a device with a voice user interface that can be manifest a new way of experience?
It was clear to us that each has its advantages in the user experience. Second, are the methods we use to design in a visual design compatible with physical and auditory design? To be able to answer these questions. We created a mind map to delve deeper into the research questions and explore them in sessions of interviews and user tests, as I will talk about it later.

In the current situation Our users have difficulty navigating a physical voice user interface
I created a map that maps behaviour made using a voice interface and those made from a visual interface.

I had no information about user behaviour with a physical device working with a voice interface. That's why we decided to create a user study that would answer some basic questions.
(1) How does a user respond to a voice device without a visual threshold?
(2) How does he perform the onboarding process?
(3) What happens when we attach a visual screen to the messages he receives from the voice interface? Will he get confused, or will it make it easier for him?

We convince the stakeholders: Develop an MVP product to conduct “Research by Design.”
The only way we could get an answer is to convince the stakeholders in our company to develop an initial prototype that will contain an onboarding experience with visual navigation for the existing device and then perform user tests.

We started by testing 7 participants with usability testing with the current device. We find some important insights about the device’s usability. We made a formative i order to identify warning lights and convince the stakeholders to perform a broader summative test on children, starting by testing 9 participants with usability testing with the current device. We find some important insights about the device’s usability.

After that, we conducted research with the help of a series of in-depth interviews to understand the needs of the user and the sub-user, who are the parents

After conducting the test, I analysed the data according to the accepted method in UX research.
After understanding where improvements need to be made, I mapped and coded the components to find repetitive behaviours.
Main research insights was
(1) A device with a voice interface works better for the user when it can be controlled with a visual app.
(2) It's better not to force users to go through tutorials during the onboarding stage
(3) Refraining from forcing users to go through tutorials during the onboarding stage is better.
According to this conclusion, we began to build the characterization of our board in this way. In the commission's centre, I placed the daily goal setter as a component that generates the improvement trend.
