The T-Stick was developed and built in the IDMIL by Joseph Malloch, in collaboration with composer D. Andrew Stewart and performers Fernando Rocha and Xenia Pestova. The physical input device can sense where and how much of its surface is touched by the performer, as well as tilting, shaking, squeezing and twisting gestures. Unlike most digital musical instruments, the T-Sticks exist as a family, with soprano, alto, tenor, and bass members.
