Context Toolkit: Tutorial: Introduction
The Context Toolkit
was developed to help context-aware application developers built applications
more easily. A graphical user interface (GUI) toolkit, separates the act
of obtaining user input from acting on it. A GUI widget mediates between
the user and the graphical application. We treat context in an analogous
way. In much the same way, the Context Toolkit separates the act of obtaining
context from acting on it. A context widget mediates between the environment
and the context-aware application. For more information on context and
context-awareness, see [1].
In this tutorial, I will describe the components in the Context
Toolkit, namely widgets, servers and interpreter. I will describe each
first in an abstract way and then concretely, stepping through the actual
code. I will describe how to use these components to build an application,
an In Out Board and present the code for each. Finally, I will provide
an installation guide for the Context Toolkit.
