cPost-it: Context-based information sharing system

Abstract

In this paper, we propose cPost-it, which allows users to share various types of media data in public places by exploiting context such as the user's identity, location, time, intention, and object's identity. The proposed system consists of three key components, i.e., 'cPost-it Client' allowing users to retrieve (augment) digital messages on the real-world objects, 'cPost-it Object' augmenting shared digital information, and 'cPost-it Server' managing the information. The cPost-it provides location based service (LBS) by retrieving the embedded information from the physical objects. Also, it provides the personalized information by exploiting the user's identity, location, time, etc. According to the subjective evaluations, the proposed cPost-it framework may play important roles in sharing information for the ubiquitous computing environment. © Springer-Verlag Berlin Heidelberg 2003.
