Visualization-based Tracking System Using Mobile Device

Services monitoring freight vehicle on route have been responding an increasing number of demands of goods owners. This chapter proposes a visualization-based tracking system using mobile device to enable users to keep track of the status of their freights ubiquitously in real time by viewing comprehensive graphs on mobile devices. The system comprises a moving device implemented on vehicle, a mobile device serving as owner’s controller, data transmission line, and map service. Data of location and conditions of vehicle from moving device are transmitted to mobile device to display as graphs. Based on space-time cube, we developed a cube to visualize location and freight weight, where location changes over time and goods weight at locations and over time. A software of diverse display modes was implemented to convert collected data into visual graphs to facilitate users’ comprehension on the location of vehicle and the status of their goods in real time.
