Abstract

The thesis presents and discusses the processes that lead to the development of a tangible toolkit for supporting design workshops aimed at building tangible interfaces with children. The toolkit, called BugBits, was used to explore and instantiate participatory design workshops with children enabling them to be creative and develop new prototypes. BugBits was tested in three case studies with children of different ages. The first study was conducted in a modern art museum, where children aged between 13 and 15 years old (N=185) built personalised artefacts with the toolkit. The artefacts were then used to perform an augmented visit to some of the exhibition rooms of the museum. The second study (N=31) was conducted in a kindergarten with children between 3 and 6 years old. The toolkit was adopted to perform two educational exercises about colours characteristics. The third study (N=24) explored how the toolkit can be used to instantiate creative processes during participatory design workshops with children between 7 and 11 years old. During the studies, qualitative and quantitative data were collected and analysed. The outcomes of the analysis show that the toolkit can be used with success to keep the children engaged (study 1, 2, 3) and obtain an active and effective participation (study 3) and allow them to build new and evolving TUI prototypes (study 3). By retrospectively reflecting on the process, the thesis presents the KPW process to guide and instantiate the design of generative tools for TUI design with children. The KPW process poses particular attention to the children roles, and how the technological choices affect the design.
