This state-of-the-art book explores the implications of contemporary trends that are shaping the future of museum experiences. In four separate sections, it looks into how museums are developing dialogical relationships with their audiences, reaching out beyond their local communities to involve more diverse and broader audiences. It examines current practices involving crowds, not as passive audiences but as active users, co-designers, and co-creators; it looks critically and reflectively at the design implications raised by the application of novel technologies, and by museums becoming parts of connected museum systems and large institutional ecosystems. Overall, the book chapters deal with aspects such as sociality, creation, and sharing as ways of enhancing dialogical engagement with museum collections. They address designing experiences - including participatory exhibits, crowdsourcing, and crowd mining - that are meaningful and rewarding for all categories of audiences involved. Museum Experience Design reflects on different approaches to designing with novel technologies and discusses illustrative and diverse roles of technology, both in the design process as well as in the experiences designed through those processes. The trend of museums becoming embedded in ecosystems of organizations and people is dealt with in chapters that theoretically reflect on what it means to design for ecosystems, illustrated by design cases that exemplify practical and methodological issues in doing so. Written by an interdisciplinary group of design researchers, this book is an invaluable source of inspiration for researchers, students, and professionals working in this dynamic field of designing experiences for and around museums.
