paradigm of human-computer interaction. In this chapter, we discuss a growing space of interfaces in which physical objects play a central role as both physical representations and controls for digital information. We present an interaction model and key characteristics for such "tangible user

Prototyping is an important part in research and development of tangible user interfaces (TUIs). On the way from the idea to a working prototype, new hardware prototypes usually have to be crafted repeatedly in numerous iterations. This brings us to think about virtual prototypes that exhibit

There is a long history of Tangible User Interfaces (TUI) in the community of humancomputer interaction, but surprisingly few of these interfaces have made it beyond lab and gallery spaces. This thesis explores how the research community may begin to remedy the disconnect between modern TUIs

Abstract: Like the prehistoric twig and stone, tangible user interfaces (TUIs) are objects manipulated by humans. TUI success will depend on how well they exploit spatiality, the intuitive spatial skills humans have with the objects they use. In this paper we carefully examine the relationship

The metaDESK is a user interface platform demonstrating new interaction techniques we call "tangible user interfaces. " We explore the physical instantiation of interface elements from the graphical user interface paradigm, giving physical form to windows, icons, handles, menus

Sensetable is a system that electromagnetically tracks the positions and orientations of multiple wireless objects on a tabletop display surface. The system offers two types of improvements over existing tracking approaches such as computer vision. First, the system tracks objects quickly and accurately without susceptibility to occlusion or changes in lighting conditions. Second, the tracked objects have state that can be modified by attaching physical dials and modifiers. The system can detect these changes in real-time. I present several new interaction techniques developed in the context of this system. Finally, I present several applications of the system, the most thoroughly developed of

In this paper we discuss the lessons learned creating a tangible user interface to teach argument to children. By gradually and iteratively introducing our technology we were able to isolate the effect of the physical affordances versus the technology components of our interface.

In this paper, we seek to identify interesting sources of metaphor for tangible user interfaces (TUIs). We begin by doing a systematic exploration of the design space that results from constructing simple TUI devices. From this we argue that a new set of metaphors are needed for this domain. From
