The Safe-Tag

A light based information system for rescue workers

A 3-week project in collaboration with Nick DeJesus based around helping people involved with natural disasters. We discovered that communication between first response teams is often unclear and yet extremely necessary. Inspired by a "throwie", a type of graffiti that is simply a battery, a magnet, and an LED that thrown onto various surfaces; we wanted to create a simple device that rapidly conveys information with light. So we created the Safe-Tag, a device that uses 3 colors to convey information to onlookers. Blue for medical assistance needed, green for a safe zone or no help needed, and red for a hazardous zone that should be avoided. Worn on the person with a carabiner, or attached to metal surfaces with a magnet.
