“Interactivity”… in the technological architectural Design

In the actual phase of the Architecture, the technical component can be the result of an interactive design process, that includes - without gaps - ideas, evaluation of performances, modifications, and … construction of the object. This effect comes from a new form of interaction between the designer and the design. (Kolarevic 2003, Eastman 1985, Mitchell 1977). This relationship is growing up, like something “dynamic”, “flexible”, “responsive”. The interaction is the core of new methodologies and the new design paradigm, like the Building Information Modeling, the 3D digital manufacturing, the Collaborative Design, the Human-computer interaction. We think that the added value of the new “design system”, passes from that of the information (data contained in the system) to that of the “interaction” (Beesley, Williamson 2004). Technological design becomes not only computer-mediated but interactivity mediated (McCullough, 2004, Saffer 2006). The interaction starts identifying a parameter, a basic element, that can be a different object: a constructive component in a simulation model, a geometric primitive a piece for a prototype (Piegl, Tiller 1997,Kolarevic 2003). The interaction with the designed components becomes a step, of a concept of the interaction with the build component: we can design a technical component, and immediately after, build it (Toriya 2008) The different levels of interactivity, currently possible in the architecture design (between different actors, between design models and designers, between prototypes and actors) reduces, every day, the gap between the design idea of the technological element, and its construction that includes the expected performances. May be the next step of this interaction dimension to obtain a built architecture as interactive as the process that has designed it?
