As part of a team at Project:Possibility, I was involved from 2012-2013 with the Mobile Bus Route Tracker (MBRT) Project.
The goal was to develop an Android application to help someone who is blind navigate their bus route. By using the Android geofencing and speech APIs, we built an application that alerts a blind person on a bus when they are approaching their bus stop destination.
The GitHub Repository for the project is availableĀ here.
