There have been many research efforts devoted to tangible user interfaces (TUIs), but it has proven difficult to create a definition or taxonomy that allows us to compare and contrast disparate research efforts, integrate TUIs with conventional interfaces, or suggest design principles for future efforts. To address this problem, we present a taxonomy, which uses metaphor and embodiment as its two axes. This 2D space treats tangibility as a spectrum rather than a binary quantity. The further from the origin, the more ldquotangiblerdquo a system is. We show that this spectrum-based taxonomy offers multiple advantages. It unifies previous categorizations and definitions, integrates the notion of ldquocalm computing,rdquo reveals a previously un-noticed trend in the field, and suggests design principles appropriate for different areas of the spectrum.
