Summary
In this work we present a method to intuitively issue control over
devices in smart environments, to display data that smart objects
and sensors provide, and to create and manipulate flows of information
in smart environments. This makes it easy to customize smart environments
by linking arbitrary data sources to various display modalities on
the fly. Touchscreen smartphones -- as readily available multi-purpose
devices -- are used to overlay real objects with virtual controls.
We evaluated this system with a first qualitative user study.
