Abstract
Designing tangible user interfaces (TUIs) means to deal with a complex number of issues related to the particular mixture of the physical and digital space. While a number of existing guidelines and frameworks propose issues and themes that are relevant during design, we still miss a more specific guidance on how to address such issues. This chapter analyses the difficulty of designing and developing TUIs by considering the principle of metaphors. Based on an analysis of the different types of targets of metaphors in TUIs, we identify the complexities of TUI adoption by users across physical, digital, and application domains. We propose a series of questions that support designers and developers in dealing with these complexities in the context of a TUI for collaborative planning and discussion of urban concepts. Our work is based on and illustrated through various insights collected during the development of the “ColorTable”, a complex TUI for collaborative urban planning.
