Pervasive Computing has postulated to invisibly integrate technology into everyday objects in such a way, that these objects turn into smart things. Not only a single object of this kind is supposed to represent the interface among the "physical world" of atoms and the "digital world" of bits, but a whole landscapes of them. The interaction among humans and such landscapes of technology rich artifacts happens to be more confluently, rather than on a per device basis. To address the confluence among humans and computing landscapes we study we study human gesticulation and the manipulation of graspable and movable everyday artifacts as a potentially effective means for the interaction with the physical environment. In detail, we consider gestures in the general sense of a movement or a state (posture) of the human body, as well as a movement or state of any physical object resulting from human manipulation. Further, based on the tangible user interface paradigm, we pr...
