What this question tests
Accessibility centered product design, rethinking a fundamentally visual product for a non visual user.
How to approach it
- Clarify the core need: blind users cannot see photos, so the product must convert visual content into another sense, primarily audio.
- Identify pain points: existing apps rely entirely on visual browsing, screen readers give generic and often unhelpful photo descriptions.
- Prioritize rich, accurate audio description over any visual UI improvements, since audio is the primary interface for this user.
- Propose AI generated detailed audio descriptions of photos, going beyond generic alt text to describe scene, people, and mood.
- Add voice controlled navigation and capture, letting users take and organize photos hands free using voice commands.
- Define success as task completion rate for common actions (viewing, organizing, sharing a photo) using only audio and voice input.
What a strong answer includes
- Treats audio as the primary interface, not an add on, correctly reframing the whole product around a non visual sense.
- Proposes a concrete mechanism, AI generated rich audio descriptions, that goes meaningfully beyond generic screen reader alt text.
- Gives an illustrative number, e.g. assumes current generic alt text correctly conveys photo content only 40 percent of the time.
- Adds voice controlled capture and navigation, addressing the full task flow, not just viewing existing photos.
Common mistakes
- Designing a visually oriented app with audio as an afterthought rather than the primary interface.
- Relying on generic, low quality alt text instead of proposing a richer description mechanism.
- Ignoring the photo taking and organizing flow, focusing only on viewing existing photos.
Likely follow-up questions
- How would you test this with actually blind users?
- How would AI generated descriptions handle ambiguous or emotional photos?
- What would you measure to know this genuinely worked for them?
