Preserving Context with Context Capsules

Contents

Mobile context-aware applications require sources of context information to drive more appropriate behavior. One valuable source of context information is context that already exists. Unfortunately, the situation an application is currently in and the situation in which a piece of context is initially used may differ by properties such as time and location. The further an application is away from the situation in which a piece of information was initially used, the more additional details it needs to be able to reuse it. In this paper we present the concept of a context capsule that facilitates the inclusion of the information necessary for context reuse.
