Demo Abstract: Lightweight Continuous Indoor Tracking System

Indoor tracking and navigation is a fundamental need for pervasive and context-aware smartphone applications. Although indoor maps are becoming increasingly available, there is no practical and reliable indoor map matching solution available at present. In this demo abstract, we describe a working prototype of a novel, robust and responsive tracking technique that is extremely computationally efficient (running in under 10 ms on an Android smartphone), does not require training in different sites, and tracks well even when presented with very noisy sensor data. The tracking system requires zero user effort (wardriving, fingerprinting, etc.) – only the floor plan is required. We also demonstrate how it is able to accurately track the position of a user from accelerometer and magnetometer measurements only (i.e. gyroand WiFi-free). We believe that such an energyefficient approach will enable always-on continuous background localisation, enabling a new era of location-aware applications to be developed.
