3D Tabletopstangible tabletop interaction with
3D projection in such a way thatany tangible on a table can beaugmented with visual contentcorresponding to its physical shape,position, and orientation.
The tangibles can simultaneouslyserve as input and output devices,and multiple users can collaborateby interacting with both thetangibles and the tabletop.
Here, we present three ofthe very first examples of tangible
3D tabletops and discussthe potentials and limitationsof employing this novel typeof interface.
There has recently been a dramaticincrease in multitouch tabletopinterfaces, but like most physicaltabletops, these interfaces are flatand two-dimensional. In our researchlaboratory, CAVI [ 1], we have forthe past four years examined thepotential of extending the tabletopinterface into the third dimension[ 2, 3, 4]. We have drawn inspirationfrom interfaces that combine tabletopswith physical objects (tangibles) thatfunction as input devices [ 5]. In doingso, we have explored how tangibleinterface components can also becomeoutput devices by using 3D projection,also known as projection mapping.
