Synopsis

ArcheoTWIST (ArcheoTUI ShapeTape) is a tangible interface that integrates a mechanical solver for simulating physically-based deformations in order to validate hypotheses in the field of Archaeology. The aim is to provide archaeologists with intuitive tools to study the suffered deformations of acquired 3D virtual objects by the application of forces on them. Archeologists can thus interactively validate or reject deformation hypotheses. The handed manipulation of a physical tape allows archeologists to better understand the chronology of the different deformations of archeological findings and thus the retrieval of their original shapes. The first prototype focused on the manipulation and deformation of staples discovered at an archeological site in Alexandria in Egypt.

Using ArcheoTWIST, a user bends a deformable tape that is sensed by computing resources: the resulting deformation is mapped to the archeological fragment that is displayed on a monitor.
