Safe Trek Android App using built-in Accelerometer and Magnetometer

Abstract

Trekking is a hobby to some people. But it has some risk also. The main risk is that we may miss somewhere else as we don’t know the direction. There are some mobile apps which provide direction using GPS. The disadvantage is that in the dense forest signal strength is weak and also GPS doesn’t provide interior routes. For that we have proposed an idea that the paths we are travelling are recorded by automatically drawing line on the screen using built in accelerometer of the android phone. Instead of using network to find path, our idea is to find path by using built-in accelerometer and magnetometer. The accelerometer will record the distance covered by the user and the magnetometer will trace the directions of the user. The app will continuously record both the information and when the user needs to return to their path it will give information recorded so far. The user can easily backtrack to their path.
