The proposal outlines a mobile app that helps users navigate street directions. The main feature of the app will be displaying directions with waypoint markers overlaid on a live video feed. The app will take advantage of the phone's GPS coordinates and internal orientation sensors to achieve this.
I chose to use Android as opposed to iOS because of my familiarity with Java.
Battery life is one concern that has come up from the Qualcomm talk and my readings about mobile development. Because AR applications are computationally intensive and battery life is extremely limited, this app should be optimized for conserving battery. One way to do this is with efficient data transfers, as described in this blog post. Another possibility is to use a phone with a Qualcomm processor in it, since the Vuforia SDK is optimized for these processors. A third goal for battery optimization is efficient memory usage - using RAM is power-expensive. These are all things to consider while I am developing this application, and should be outlined now as opposed to later, when I may have coded myself into a power-inefficient corner.
