Product design question

Design a refrigerator for the blind.

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Tests accessible/inclusive product design: identifying real barriers blind users face with a visual appliance and designing around non-visual senses.

Clarify the user: someone who is fully blind, using screen readers and tactile/audio cues daily, versus low-vision users who may still use some visual contrast.
Identify pain points with a normal fridge: can't read expiration dates, can't see what's inside without touching everything, can't read temperature/settings displays, can't tell what's about to spoil.
Prioritize by frequency and safety: expiration/spoilage detection is a safety issue (food poisoning risk), so prioritize it over convenience features.
Propose design: voice-controlled interface for settings and inventory queries, audio labels via smart tags/RFID scanned on entry (integrated with a phone app using text-to-speech), and audio alerts for items nearing expiration.
Address interaction: tactile braille labels on shelves for organization, plus consistent voice feedback confirming door open/closed and temperature status.
Define success: reduction in spoiled/wasted food reported by blind users, and task completion time for 'find an item' compared to a sighted user baseline.

Prioritizes safety (expiration/spoilage detection) over cosmetic accessibility features, showing sound judgment on what matters most.
Proposes a concrete tech mechanism (RFID/smart tags plus voice interface) rather than vague 'make it accessible' language.
Combines multiple accessible modalities (audio and tactile/braille), recognizing blind users vary in their preferred interaction mode.
Defines a success metric tied to the real risk (food waste/spoilage) rather than generic satisfaction.

Treating accessibility as an afterthought UI tweak (bigger fonts) rather than a fundamentally different interaction model.
Ignoring the safety dimension (spoiled food, expired medication storage) which is the highest-stakes pain point.
Assuming all blind users behave the same way, ignoring the existence of low-vision users with partial sight.

How would you validate this design with actual blind users before building it?
How would this integrate with existing screen reader ecosystems (VoiceOver, TalkBack)?
What would you prioritize first if the budget only covered one feature?
