“…The design and development of the App were based on the didactic program and all the previous visit experiences following always a bottom-up approach, in fact, all the actors (researchers, museum staff, operators and parents of children/young teenagers with Autism) participated, through planned meetings (specific focus group) for discussing and defining contents and putting together different ideas strictly taking into account the concrete needs of the participants, responded to interviews and questionnaires, and compiled fact sheets for the visitors. According to previous studies on the topic [1,2,4,5,10,11,13,14,15] and past practical directed and undirected experiences already documented [10,11,12], the App is, therefore, the result of a deep analysis and further development of the original entire program (the visual agenda used during the visit, the steps of the museum visit path, and the instruments used for evaluating the overall initiative) using digital technologies.…”
