Controlling ambient information flow between smart objects with a mobile mixed-reality interface

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.
