A Solid Diagram Metaphor for Tangible Interaction

Every approach to interaction design reflects an implicit metaphor held by designers of relationships between the system and user. In the case of interactive research prototypes, as found in ubiquitous computing applications, these implicit metaphors can be inappropriate to real usage scenarios. We propose a novel metaphor of tangible interfaces as being a solid diagram to which we can apply abstract notational analysis, resulting in a powerful analytic approach to interaction design. Author
