Context-enabled applications are just emerging and
promise richer interaction by taking environmental context
into account. However, they are difficult to build due to
their distributed nature and the use of unconventional
sensors. The concepts of toolkits and widget libraries in
graphical user interfaces has been tremendously successful,
allowing programmers to leverage off existing building
blocks to build interactive systems more easily. We
introduce the concept of context widgets that mediate
between the environment and the application in the same
