For the last 40 years, anthropotechnology has concentrated its efforts on the study and improvement of the working and living conditions of populations throughout the world. It guides the actors of the design processes by paying attention to the “human factor”: its social, cultural and environmental components. It therefore values a conception of techniques that respect people and their ways of thinking and acting in specific contexts. This book introduces the reader to design dynamics that combine often conflicting sets of competencies, but that are always anxious to respond to the contexts of the field.
