Design Fire Safety Alerts for People Who Cannot Hear an Alarm

You are asked to create a fire alarm that deaf people can rely on. Choose the setting it is for and the users it serves first, explain how it gets their attention when there is a fire, and say how you would judge whether it works. ```hint Walk through the moments List the situations a person could be in when smoke is detected, such as asleep, in another room or away from home, and check how each candidate design would reach them in every one. ``` ### Clarifying Questions - Is the alarm for homes, workplaces or public buildings, or is the setting mine to choose? - Should it serve only people with no usable hearing, or also people who are hard of hearing? - Are we building new detectors, or should the product work with smoke alarms already installed? - Must it pass fire-safety certification in the launch market before it can be sold? ### What a Strong Answer Covers - A chosen setting and first user segment, each compared against alternatives - Alert scenarios mapped against the ways a deaf person can be reached, with the hardest scenario handled explicitly - A prioritized design and MVP that accounts for existing products and their gaps - How the design keeps working when one alert path or power source fails - Success metrics with guardrails, including how false alarms are kept in check ### Follow-up Questions - The buyer is often a landlord, an employer or a relative rather than the deaf user. How does that change the design and the way you distribute it? - How would you test that the alarm wakes sleeping users without putting anyone at risk? - How would you extend the product to other emergencies, such as carbon monoxide or severe weather warnings?
