Advanced GIS applications and GPS loggers allow travelers to record their own tracks and later examine, modify and share them. Searching for the areas of interest, AOIs, however, is often not an easy task, especially with long routes. This paper proposes a system for inferring and focusing AOIs, from a GPS trace. The proposed system consists of three main functions: fragmentation, defragmentation, and focusing. The fragmentation detects the changes of the travelling pace and decomposes the GPS trace into a large number of small fragments according the traveling pace while the defragmentation composes adjacent fragments into one fragment which is inside the AOI. The focusing provides a Focus+Context+Glue map where the Focus is an area of a large-scale map including the AOI that enables users to understand details of the AOI. We have developed a prototype of the proposed method that includes the above features and evaluated the feasibility and advantages of the proposed system.
