The anatomy of a context-aware application
Andy Harter, Andy Hopper, Pete Steggles, Andy Ward, Paul Webster · 1999
We describe a platform for context-aware computing which enables applications to follow mobile users as they move around a building.The platform is particularly suitable for richly equipped, networked environments.The only item a user is required to carry is a small sensor tag, which identifies them to the system and locates them accurately in three dimensions.The platform builds a dynamic model of the environment using these location sensors and resource information gathered by telemetry software, and presents it in a form suitable for application programmers.Use of the platform is illustrated through a practical example, which allows a user's current working desktop to follow them as they move around the environment.
