Over 200 million 911 calls are made every year1. For first responders and dispatchers fast flowing information and communication during an ever-changing emergency is crucial to saving lives. No One Left Behind has focused on improving emergency response by managing and presenting data to 9-1-1 dispatchers and has improved upon the existing process of dispatching. Currently, the standard way of first responders receiving information is through a slow relay over radio between dispatcher and first responder. With No One Left Behind we improved communication, enhance situational awareness, and better crisis remediation through our easy to use UI. NLB is designed to utilize user’s smartphones for a quicker yet more accurate and detailed description of what is happening. Furthermore, NLB was built to improve upon ‘Areas of Refuge’ that currently lack in assisting the disabled. Our UI has been tailored for quick and easy use by both dispatchers and users.
