There were an estimated 50 million people worldwide living with dementia in 2017 and this number will almost double every 20 years, reaching 82 million in 2030. Design has significant potential to contribute to managing this global concern. This book is the first to synthesise the considerable research and projects in dementia and design. Design interactions is a new way of considering how we can improve the relationship between people, products, places and services and of course technology trends, such as the ‘internet of things’, offer great opportunities in providing new ways to connect people with services and products that can contribute to healthier lifestyles and mechanisms to support people with acute and chronic conditions. In light of this, the book explores the contribution and future potential of design for dementia through the lens of design interactions, such as people, contexts, material and things.
