The museum world is rapidly changing from being collection-centred to being community-centred and for the public. Apart from broadening access to collections through, for example, digitisation initiatives, new ways of involving the public more meaningfully and at various levels have emerged. Experiences inside museums have become more engaging, by extending the experience beyond the physical visit, or by involving the public in various forms of crowdsourced stewardship of collections. In this book, we explore the design implications that go along with these developments, all concerned with diversifying and making the engagement of the public in museum experiences more rewarding. We focus on the design implications associated with museums reaching out to crowds beyond their local communities, on experimenting with novel technologies and on conceiving experiences embedded in connected museum systems and large institutional ecosystems. By looking at and reflecting on trends, we attempt to sketch a picture of how future museums will change and, particularly, how they will relate to their public as a result of responding to or embracing these trends.
