Point &; click mediated interactions for large home entertainment displays

This work introduces and discusses the implementation details of a novel concept for a home entertainment system together with an affordable controlling interface that uses point & click interactions in order to create, mix and manipulate media screens within the same projection-based display. Scenarios for single and multiple viewers are discussed with users being able to create, reposition, resize, and control their own-defined media screens. The standard and familiar WIMP interaction techniques are transferred from PCs to home entertainment using a motion-sensing remote controller. An optional system feature is described for the automatic configuration of such media screens by analyzing the home environment using computer vision techniques. Observations from initial user studies are reported with regards to the perceived usefulness and acceptability of the proposed system. The main benefit introduced by this work is that of a large entertainment display that becomes shared and personalized while it is being adapted and fit into the home environment.
