Producing a sonohaptical experience with Arduino

---

A 3-axis machine controlled by finger movements makes for a unique touch and sound performance.

The collaboration of Jakub Koźniewski and Dmitry Morozov (who you may know as ::vtol::) have devised a slick audio-tactile project that they call The Finger. The mechanism, which performed at the recent MusicMakers Hacklab at the 2015 CTM Festival in Berlin, is comprised of two parts.

First, Koźniewski designed a 3-axis machine dubbed Sonohaptic. This device brings together both tactile sensations and sound by moving its robotic head equipped with a piezo sensor along the arm of the wearer, picking up tiny vibrations and translating them into some sci-fi-like tunes.

Meanwhile, One-Finger is a wireless controller created by ::vtol:: that enables sound production through the use of a finger equipped with a number of components. The wearable contraption is embedded with various sensors (bend, sonar, tilt and pulse), a Nord Modular G2, an Arduino Uno (ATmega328), as well as a Bluetooth module for communication.

When the pair is combined, a user can control the Sonohaptic through finger movements as it touches another person with the machine, thereby producing a “sonohaptical” experience. Intrigued? Not only can you read about the project here, be sure to watch it in action below.
