The Hapstrument

2022 | Derrek Chow, Jonathan Lane-Smith, Sahand Ajami

We present the Hapstrument, a novel bimanual haptic device for musical expression. Composed of two Haply 2diy haptic force feedback devices, the instrument allows a user to control pitch with one hand, and excitation with the other. We evaluated the Hapstrument's playability in an informal study with musicians and validated our original design goal through a live performance with the Hapstrument.
