Design as inventive process. The contribution of design semiotics

Intended as planning tension – that is to say an intentional act moved by a state of necessity and oriented towards the achievement of a goal – design has a role always more important in the construction of the “idea of the future”. But the future not only needs to be con-structed, but firstly it needs to be interpreted. The sense of the future (what we desire being) influences the sense of the present (what we are able to be). But through which possibile means is it possibile to elaborate a plausibile hypothesis as a response to a problematic condition (lack, inadequacy, desire)? What does it mean in semiotic terms, to interpret the sense of the future?
