Software Engineering Issues in Developing a Context-aware Exhibition Guide System

Context-awareness is a key feature of ubiquitous computing, but it is difficult to develop context-aware systems because they are complex and because developers are not familiar with the development methodology for the systems. In this paper, we introduce a method to apply software engineering techniques when developing a context-aware system. Based on our experience in developing a context-aware exhibition guide system, we show how to elicit requirements, how to model context, how to determine system architecture, how to design the system, and how to implement the system. Our study will help developers to efficiently develop context-aware systems according to software engineering principles.
