There has recently been a dramatic increase in multitouch tabletop interfaces, but like most physical tabletops, these interfaces are flat and two-dimensional. In our research laboratory, CAVI , we have for the past four years examined the potential of extending the tabletop interface into the third dimension [2,3,4]. We have drawn inspiration from interfaces that combine tabletops with physical objects (tangibles) that function as input devices . In doing so, we have explored how tangible interface components can also become output devices by using 3D projection, also known as projection mapping. A tangible 3D tabletop combines tangible tabletop interaction…
