Design a Camera-Equipped Smart Mirror: Pick the User, Use Case and First Version

You are given three building blocks: a mirror, a camera and an internet connection. Use them to create a new product. Explain who the product is for, what problem it solves, what its first version does, and how you would judge whether it succeeds. ```hint Let the parts suggest a moment People stand in front of a mirror at predictable times and for predictable reasons. Ask what a camera could notice in those moments and what a connection could add, and favor an idea that needs all three parts rather than just one. ``` ### Clarifying Questions - Is the product meant for homes, for businesses such as clothing stores, gyms or salons, or is that my choice? - May I add supporting parts, such as a display behind the glass, a speaker or on-device processing, or must the design rely on only the mirror, the camera and the connection? - Should the product fit Google's existing devices and services, or can it be any product? - Where would target users accept a camera, for example a bathroom, a bedroom or a living room, and should privacy rule out some uses? ### What a Strong Answer Covers - A range of use cases that make all three parts essential, rather than a mirror that only displays weather and a calendar. - A chosen user and problem, justified by how often the moment occurs, how painful it is and how well the parts fit it. - A concrete first version with prioritized features and a convincing answer to why it beats an app on a phone or TV. - Success metrics with guardrails, and the privacy, accuracy and business-model risks of putting a camera behind a mirror. ### Follow-up Questions - Why would someone buy this rather than prop their phone against the wall? How would you test that before building hardware? - How would you earn the trust of people who are uneasy about a camera in their home? - If you had to sell the product to businesses instead of consumers, which kind of business would you start with, and what would change?
