By Dan Lockton, PhD. “Aims to give practitioners a more nuanced approach to design and behaviour, working with people, people’s understanding, and the complexities of everyday human experience. It’s a collection of design patterns—and a design and research approach—for exploring the interactions between design and people’s behaviour, across products, services and environments, both digital and physical.”
