The Interactopus is an interactive sculpture that uses eight photocells mounted on its extremities to control sound and live video projection. The light signals from the cells are mediated through the analogue version of the ArtBus board. Using analogue, rather than digital, accommodates the more varied control (through changes in light) that are required to interact with this object.
The ArtBus then communicates through USB with max/msp and Gem to produce changes in sound and video signals. Live performance with this instrument is part of an ongoing research into human/computer interaction. The ArtBus board has proven readily adaptable to many forms of interface, and will surely be incorporated into further studies in this area. -Chris B.
