What this question tests

Accessibility-first product design grounded in specific sensory constraints.

How to approach it

  1. Define the user: a blind or low-vision person who cannot rely on a visual display to set or read the time.
  2. Identify pain points with existing alarm clocks: visual-only displays, touchscreen controls with no tactile feedback, and visual-only alarm indicators.
  3. Prioritize audio and tactile interaction: voice-based time setting, spoken time announcements, and physical, distinctly-shaped tactile buttons.
  4. Design the alarm itself to use a distinct escalating sound plus optional vibration, avoiding reliance on any visual cue.
  5. Ensure compatibility with existing screen-reader habits and conventions blind users already rely on, rather than inventing a new interaction paradigm.
  6. Define success metrics: successful wake-up and set-time accuracy, validated with blind user testing.
