A computational location model based on relative information

Abstract

In this paper, we proposed the concept “relative location” as a complementary presentation to the traditional “absolute location”, which were considered the traditional expression of locations and have pervaded the current locations based services (LBS). Two methods were introduced to make relative location computable and more useful. Prototypes with Data visualization interface were designed and evaluated to test usability of the proposed methods. User experiments shown that integrating relative location information into computing system may help to improve usability of location based applications.
