TL;DR

A method for expressing requirements for sensed context information in terms of relevant quality attributes plus properties of the sensors that supply the information is developed.

Abstract

We present a way of analyzing sensed context information formulated to help in the generation, documentation and assessment of the designs of context-aware applications. Starting with a model of sensed context that accounts for the particular characteristics of sensing, we develop a method for expressing requirements for sensed context information in terms of relevant quality attributes plus properties of the sensors that supply the information. We demonstrate on an example how this approach permits the systematic exploration of the design space of context sensing along dimensions pertinent to software development. Returning to our model of sensed context, we examine how it can be supported by a modular software architecture for context sensing that promotes separation between context sensing, user interaction, and application concerns.

A conceptual framework is presented that separates the acquisition and representation of context from the delivery and reaction to context by a context-aware application, and a toolkit is built that instantiates this conceptual framework and supports the rapid development of a rich space of context- aware applications.

Critical Issues in User Interface Systems Engineering examines issues which are relevant to a wide range of people involved in the field: software engineers who develop and implement systems, system modellers who develop representations for them, and tool builders who provide the necessary tool support.
