摘要：

The functionality of architectural framework developed by computer laboratory of the Univerity of Cambridge, for interactive context-aware applications, is discussed. Architecure is based on the Model-View-Controller (MVC) paradigm. Architectural framework use the SPIRIT (Spatially Indexed Resource Indentification and Tracking) backend, which maintain a world model based on sensor's real-world observations. It uses an indoor ultrasound location system for tracking small tags. SPIRIT evaluates spatial relationships between objects and people in the world model. MVC enables users to represent a model in multiple ways by attaching multiple views. It makes communication between the user and application more intelligible. It allows designers to use object-oriented design to construct and communicate domain models. It provides a set of abstractions such as the context component to simplify the process of communicating the application's workings to the user.
