Mapping Physical Objects to Digital Functions: A Tangible Interface for Querying and Navigating a Multimedia Database (PDF available)

In this work we propose a set of guidelines for tangible interfaces (TUI) for mapping physical objects and digital functions. These guidelines emphasize an aspect that has been only partly analyzed so far in TUI research: the role of the object shape as a means for suggesting how to manipulate the artifacts. The peculiarity of the proposal – general enough to be used for different application domains – is the mapping to discrete and continuous digital functions Continue reading

This work is part of a research targeted at experimenting the use of physical artifacts for the retrieval of multimedia information. Tangible interfaces, that couple physical artifacts to digital data, are described in different research works, and a number of studies focus on tangibles for children. In spite of that, most of the work done for the kids is related to gaming or learning. This work is focused on a less explored domain Continue reading
