The TactBall is a Human-Computer-Interface designed to control live performances (music / video / light /...). An elastically suspended half-sphere is used to move magnets in 3 axis, whose magnetic fields are sensed by Hall-Effect sensors and translated to performance control data by means of a microprocessor. The TactBall can be operated with one or two hands - can be slapped or pushed/pulled or just slightly touched, is very sensitive and can be used simultaneously in a percussive-trigger-like manner (as a drumpad, for example) and in a continuous-controller-like manner (as a mod-wheel and the like).
