The most memorable part was that interviews and user tests with children were completely different from those with adults.
Since children responded with actions rather than words, it required short and clear questions,
visual guidance, and immediate feedback. Because their attention span was short, the tests were divided into short rounds, and I used storytelling-style explanations and real toys to help them stay engaged. Grouping similar questions also worked well for their short memory span.
Through this, I learned that adapting research methods to the user’s characteristics is key to gaining meaningful insights.

At first, I focused on designing a product that teaches responsibility.
But I learned that for children, motivation from “I want to” works far more effectively than “I have to.” Instead of instructions, I designed small rewards, instant feedback, and emotional connection,
so that behavior change could naturally turn into habit.
In this project, the key was to use psychological persuasion in a positive and motivating way.
