The second menu item allows the user to choose a route name and then click the start button to initiate data collection using accelerometer and gyroscope sensors embedded inthe smartphone. A stop button is also there to stop the process after which the data will be automatically sent to the web server at an appropriate time when the Internet is available.

The user can enter a start and end location (or select them on the map) and then click “Go” which will generate one or more accessible routes between the given endpoints.
