However, the design of such systems is complicated, as it involves a large number of stakeholders and specialists. Additionally, the functional components need to be carefully orchestrated to deliver a rich user experience. Thus, there is a need for further research on tools and methods that facilitate the process. In this paper we present the design and development of a mixed reality installation for the Museum of Marble Crafts in Tinos island in Greece, which places visitors in the role of the crane operator and they have to complete challenges in a gamified version of the old quarry. The system lets users operate a tangible controller and their actions are executed by digital workers in a rich 3D environment. Our design approach involved iterative prototyping, research and co-design activities. The creative process has been supported by a series of organized workshops. The evaluation results indicate that mixed reality can be a promising medium for rich interactive experiences in museums that combine tangible and intangible heritage.  a25719408 (ISSN)
