eMU-Public is designed to for the public to identify emergencies and send out notifications around the University of Melbourne, Parkville campus. Users will receive a message once an OHS officer makes a response to it. Thousands of geo-coded QR tags will be placed around the campus so users can quickly scan it to get accurate location information, not matter outdoors or indoors. FirstAid and AED toolkits are also marked on the map, and the calculation of fastest walking route between user's current position and any toolkit is supported.
