Interactive Design: Then and Now

Abstract

In interactive design, the creation of a product is considered to be constrained by 3 factors: 1. the experts' knowledge: even if own knowledge leads to secured solution during design, crossing of dierent knowledge ensures the creativity. This statement implies that cognitive interaction is required to well-drive the product engineering, 2. the end users' satisfaction: a product that not allows the realization of end-user perception will not be successful. This evidence impose to handle new tools enabling the consideration of sensorial interaction during design, 3. the realization of functions: a product is created for assuming spe-cic behaviours in a physical environment, providing new functions to each element of this environment. This concept requires to sooner exhaustively identify physical interactions that are realized between physical components of an environment. The challenge of interactive design is really to supply ecient solutions for leading product engineering: it is proposed from the analysis of cog-nitive, sensorial or physical interactions. Interactive design suggests the modelling of a design problem by regarding , identifying and modelling interactions and induced behaviours withon in an environment hosting the product. Around the concept of interaction, some systematic methods aid to the description of environment mechanisms. The description of interactions and component behaviours constitutes the source of the model of the design problem. These techniques involve the using and integration of: creativity methods, combined Articial Intelligence and numerical techniques, sensorial approach, knowledge engineering tools.
