The history of design and the history of technological innovation are indissolubly intertwined in this manual, which tackles a number of disciplines. Beyond the furniture design field – which often exemplifies in excellent fashion the farthest–reaching lines of design research – a wide array of sectors is taken into consideration: from the design of technical objects to graphic design and fashion, from cars to social design, with constant attention being paid to the effects and outcomes of the design project on the evolution of social customs in its real–life applications.
