Abstract:
This article introduces two examples aiming to data acquisition and processing based on interaction to the environmental position and dynamic flow. One is the measurement of pen motion wore with acceleration and angular rate sensors, fused with the environmental image data. Another is the congestion evaluation of traffic dynamic flow, when floating probe car or roadside beacon or traffic center interacts each other. Data processing method is described by mathematical models. Towards to ubiquitous computing, small but multiple measurements and effective data relationship definition will be important.
