For Kenya Hara, design begins with comprehension of the unknown. In contrast to 'information, ' 'exformation' describes how little we really know and thus becomes the starting point for any type of design. Based on a range of projects the book describes what 'exformation' can look like in design practice and how this conceptalters our classic understanding of information design. Following the path embarked on in Designing Design (2007) and its successor, White (2010), Ex-formation continues to explore the void, absence, and indeterminacy in contemporary design.
