Problem
SafePause Vest explored how a wearable could support safer work routines in warehouse environments. I was interested in the relationship between fatigue, timing, visibility, and small reminders that could help workers pause before stress or repetition leads to mistakes.

My Role & Research
I used user-centered design and the Double Diamond framework to move from problem framing to prototype testing. I researched workplace behavior, break-taking practices, and safety routines, then built a vest prototype with LED, buzzer, and Bluetooth trigger functions. I also ran two testing rounds and used feedback to refine comfort, timing, and clarity.

"The design challenge was not to force workers to stop. It was to create a reminder that felt understandable, timely, and respectful in a busy workplace."

Key Decisions & Learning
Testing showed that the first buzzer was too weak and the trigger logic needed to be clearer. I increased the alert frequency, added a front LED, and built a dual Bluetooth system for designated break areas. The project taught me that safety design depends on context: an alert must be visible, audible, and socially acceptable in the environment where it lives.
