How would you design a clock made for kids? ```hint Ask what the child needs time for Many young children cannot read numbers or judge how long ten minutes is. Think about which moments in a child's day depend on time, and what the child and the parent each need the clock to do in those moments. ``` ### Clarifying Questions - What age range: toddlers who cannot read numbers yet, early school children learning to tell time, or older kids? - What should the clock help with: learning to read time, following routines such as bedtime and waking up, or managing time on their own? - Is this a physical device, an app, or a wearable such as a watch? - Who buys it, and how much control should parents have over what the clock does? ### What a Strong Answer Covers - A chosen age group and the reason for it, considering both the child who uses the clock and the parent who buys it - How children experience time differently from adults, and the daily moments where that causes friction - Concrete features prioritized into a first version, including the form factor - Success metrics for a physical consumer product, plus safety, privacy and durability requirements for a children's device - How the product stays useful as the child grows ### Follow-up Questions - The clock cannot see what the child does. How would you know whether it actually helps children follow their routines? - Parents ask for a camera and microphone so they can check on the child. Would you add them? - What would you change to sell the clock to classrooms instead of families?
