Interaction for tabletop computing environment: An analysis and implementation

In the future ubiquitous computing living environment, humans will interact with computers (knowingly or unknowingly) any where by various means other than through the traditional desktop interface (e.g. keyboard and mouse). Interacting with a "smart" table could very well be one such probable scenario. In this paper, we outline and classify various possible techniques for interacting with the smart table under reasonable assumptions about the operating environment. We considered the primitive tasks of object selection, object manipulation and menu control. The classification should serve as a basis for experimenting, designing, selecting, composing and implementing a specific interaction technique for a given task to achieve high usability.
