CONTEXT
At large venues, first responders lose time on three things: finding the person, finding out their medical situation, and coordinating who has been treated. We mapped the responder journey and built around those three failures.
§ 02
OBJECTIVES
- 01Locate individuals quickly in a crowded venue
- 02Give responders instant access to critical medical information
- 03Coordinate casualty status across a response team
- 04Keep personal medical data temporary and private
§ 03
PROCESS
We mapped the first-responder journey end to end, then co-developed a wearable ecosystem combining location tracking, NFC identification, SOS activation, LED guidance and a responder-facing dashboard for triage and communication. I designed a no-app registration flow for temporary medical profiles and an end-to-end workflow spanning venue entry, profile registration, wristband activation, SOS alerts, responder access and post-event data deletion.
I CAD-modelled the wristband housing and produced interface mock-ups for registration, location, medical information and responder access.

DECISIONS
◆ DECISION LOG
No app install. Requiring a download at a venue entrance kills adoption, so registration had to work from a browser in under a minute.
§ 05
CHALLENGES
▲ FAILURE / RISK
Medical data is the whole value and the whole risk. We designed around temporary encrypted storage with automatic post-event deletion, and made responder access work offline so the system degrades safely when venue connectivity fails.

Placed Runner-Up in the Tech for Good Hackathon hosted at the Dyson School of Design Engineering, 24–25 January 2026.
