Duco - Hybrid Indoor Navigation


This paper proposes an application especially designed for indoor navigation, Duco. A hybrid approach at trying to find a solution to the problem of indoor navigation by mainly utilising pedestrian dead-reckoning (PDR) along with the aid of iOS wireless location determination systems to aid the process. Using merely the digital accelerometer and compass sensors of modern smartphones, PDR can reflect location changes in real-time with high-precision while retaining battery life at maximum. An algorithm is utilised to analyse the data from these noisy sensors to enable high success rate of detecting step count. Duco also makes use of wireless location determination systems to retrieve the initial location where PDR falls short or iBeacons to get around problematic places inside an indoor venue like stairs, elevators or signal dead-zones.
