Alarm Rug is a smart, weight-sensitive floor mat that requires users to physically stand on it to dismiss their alarm. Integrated LED lights and a companion mobile app support habit-building and morning productivity.

Alarm Rug
02problem

What needed solving

Traditional alarms are too easy to snooze. Users need a physical barrier between themselves and the snooze button — something that forces them out of bed to start their day intentionally.

01research & insights

research & insights

The best alarm isn't louder — it's one you can't reach from bed.
  • Studied morning routine behavior and identified snooze-as-default as the core failure mode.
  • Interviewed users about wake-up friction — proximity, habit loops, and the gap between intention and action.
  • Researched existing smart alarm products and found most still allow in-bed dismissal.
  • Identified the companion app as a critical touchpoint for habit tracking and routine customization.
02design process

design process

  • Redesigned user flows and interfaces for iOS and Android using Figma and Adobe XD.
  • Built interactive prototypes validating the wake-up flow: alarm triggers → user must stand on rug → alarm dismisses.
  • Designed the app with a clear hierarchy — time display, status message, and physical action prompt.
  • Integrated accessibility best practices to improve engagement and ease of use across platforms.
  • Collaborated on embedded C++ functionality for the weight-sensitive rug hardware integration.
03design strategy

design strategy

Make the physical action feel rewarding, not punishing — the app should coach, not scold.
  • Used a calming navy + periwinkle palette to reduce morning anxiety while maintaining urgency.
  • Designed a three-tab navigation (Home, Alarm, Settings) for minimal cognitive load at 7 AM.
  • Made the 'stand on the rug' prompt the single focal point — no distractions, no secondary actions.
  • Paired hardware LED feedback with app state changes for a cohesive physical-digital experience.
