Navigating Dynamically-Generated High Quality Maps on Tilt-Sensing Mobile Devices

Abstract

On mobile devices, navigating in high-resolution and high-density 2D information spaces, such as geographic maps, is a common and important task. In order to support this task, we expand on work done in the areas of tilt-based browsing on mobile devices and speed-dependent automatic zooming in the traditional desktop en- vironment to create an efficient interface for browsing high-volume map data at a wide range of scales. We also discuss infrastructure aspects, such as streaming 2D content to the device and efficiently rendering it on the display, using standards such as Scalable Vector Graphics (SVG).
