Tabletop Ensemble: touch-enabled virtual percussion instruments
We present an interactive virtual percussion instrument system, Tabletop Ensemble, that can be used by a group of collaborative users simultaneously to emulate playing music in real world while providing them with flexibility of virtual simulations. An optical multi-touch tabletop serves as the input device. A novel touch handling algorithm for such devices is presented to translate users’ interactions into percussive control signals appropriate for music playing. These signals activate the proposed sound simulation system for generating realistic user-controlled musical sounds. A fast physically-based sound synthesis technique, modal synthesis, is adopted to enable users to directly produce rich, varying musical tones, as they would with the real percussion instruments. In addition, we propose a simple coupling scheme for modulating the synthesized sounds by an accurate numerical acoustic simulator to create believable acoustic effects due to cavity in music instruments. This para...
