Although context awareness is a key component for perceptual user interfaces, we lack generic infrastructure for developing context aware applications. We propose a generic infrastructure based on context servers that store, share and archive contextual data. We describe a few applications we have built that take advantage of context sharing and context history. We then turn to the overall design of our context server and analyze in detail its services with a worked example.
