Arrays of water jets as user interfaces
Ryan E. Janzen, Steve Mann · 2007
The hydraulophone is a fun-to-play self-cleaning keyboard instrument in which each key is a water jet. Many hydraulophones are already equipped with an array of underwater microphones (hydrophones), to pick up the turbulent sound from water inside musical sounding mechanisms under each water jet. Accordingly, we propose to make greater use of the sound of the water flow.
