This device allows users to move sounds around in 3D space and affects many other qualities of the sound depending on where you move your hands. It is a kind of instrument that allows users to sculpt audio with their hands. So move your hand up - the sound goes into the ceiling, move it in a circle - the sound moves in a circle around you. In addition, it morphs sounds using various techniques. For example pulling your hands apart will make a sound stretch between them, not only time stretching the sound but also stretching it 3D space across the speaker array. Sounds change according to hand and finger movement as well as gestures. Sounds can be left in a certain position so users can build a complex 3D soundscape around them. It has many psychoacoustic principles built into the way it manipulates sound in order to enhance the spatialisation and other characteristics of the sound. The project started on the Wii in 2012 but now uses other sensors such as the leap motion.
