摘要：Visualization has become an increasingly important manner to support vehicle navigation systems and other location -based services. However, the information display on these mobile devices is an essential and complex i ssue due to the limitations in mobile devices, dynamic usage contexts and the user.s personalized preferences. Among these challenges, the main disadvantage is the limited size of the display screen, which is the important factor causing information redundancy and human cognitive burden. The objective of this study is to filter the irrelevant information for the sake of decreasing the map load and providing ada ptive spatial information visualization. In this paper, we define the core filter components by exploring the user information needs in vehicle navigation systems and discuss ing the nature of them. Furthermore, we describe the filter mechanism by integrate d these components from two aspects, focusing on building area of interest (AOI) and measuring the dynamic degree of interest (DDOI). Finally, we implement this filter mechanism with POI features and discuss the effect after spatial information filtering
