User Localization by Spatial Context Processing
Journal Title: Revista Romana de Interactiune Om-Calculator - Year 2015, Vol 8, Issue 2
Abstract
This paper presents a case study and a proposed solution for a train localization system, designed to satisfy the safety requirements specific to the railway domain, and the limits imposed by the low cost regional railway platforms. Information and data flows are used to establish a global context for train localization through a software railway platform. The train localization is based on GNSS (Global Navigation Satellite System) low precision sensors and MEMS (Microelectromechanical Systems) inertial sensors integrated in commercial mobile devices, such as PC tablets and smart-phones. The integrity requirements of such a solution, on which the life safety is the main reason of localization, are stringent. In order to satisfy all the requirements put forward the current solution proposes to source out to the crowd the localization and other services traditionally offered by train personnel. The issues raised by storage, communication, processing and visualization of data throughout the processing flow are highlighted in the paper.
