Notes

A personal safety app or SOS app is a mobile application which can be used to aid personal safety. Personal emergency notification system is an important tool for personal security and safety. Recently, there are two kinds of common emergency notification systems. One is designed to allow the user wearing a designed button with a connection to the device host at home [1]. Another is specially designed single-function phone (the phone for elders) whose back has an SOS button [2]. When unexpected something happen, users just need to push the button to secure, systems could send a message to some specific institutions or people setting in advance. However, these two kinds systems mostly do not embed GPS functions and information may not clear enough in an emergency, which motivates this project. In this paper, an emergency notification application for mobile devices will be designed. In the application, the position function of GPS and an easy user interface capable for sending emergency notification messages or phone calls are included. Users can quickly push the designed buttons for help via sending (short) messages and instant messages, both of which automatically include position information, to default emergency corresponding people or institutions.
