This book is about changing the 'spaces' of the designed world. It is about how designers think and attribute meanings to what users and clients see as important to them in the design development of projects, and how reflecting about these subjects is valuable when attributing the design choices we make. This book uncovers multiple voices and points of view of various scholars, practitioners, business people and passionate designers, all of whom explore design from such diverse perspectives as research and practice or business and philosophy, and all as drivers of how we mediate experiences and spaces. Poldma and the contributors explore diverse types of spaces, what constitutes 'designed space' and what this means for technology, business, design thinking and doing, ethics, culture, sustainability and society. They hope to provide a source for debate, for conversation and for discussion.
