Abstract. In order for a smart environment to provide services to its occupants,
it must be able to detect its current state or context and determine what actions

we have designed and implemented to help application designers build intelli­
gent services and applications more easily. We describe the benefits of our in­
frastructure through applications that we have built.
1 Introduction
One of the goals of a smart environment is that it supports and enhances the abilities
of its occupants in executing tasks. These tasks range from navigating through an
unfamiliar space, to providing reminders for activities, to moving heavy objects for
the elderly or disabled. In order to support the occupants, the smart environment must

what actions to take based on this context information. We define context to be any
