VR-based Sensor Management System for USN-based Air Quality Monitoring

摘要

We introduce a visualization system of micro-scale air quality monitoring system in the virtual reality environment. The system is targeting to provide everyday air quality by adopting VR-based visualization method. With the system casual users can get insight of air quality data intuitively. The system targets to provide interactive manipulation of actual sensors in ubiquitous environment, to retrieve specific data. Users can manipulate sensors in VR environment. To provide interactive manipulation of massive sensor data, an adaptive visualization method is proposed. For the adaptive visualization, the visualization and interaction data are separated from air quality data. With this layered approach, the visualization module can interactively decide appearances and detail levels for interactivity independently to original data quality and complexity. As an exemplar system an application with a display-wall is constructed. This system can provide accessibility for air quality data to people one public space.
