herakoi 0.2.0

A sonification tool

herakoi

herakoi is a motion-sensing sonification experiment.

It uses a Machine Learning (ML)-based algorithm for hand recognition to track in real-time the position of your hands in the scene observed by a webcam connected to your computer. The model landmarks coordinates of your hands are then re-projected onto the pixel coordinates of your favorite image. The visual properties of the "touched" pixels (at the moment, color and saturation) are then converted into sound properties of your favorite instrument, which you can choose from your favorite virtual MIDI keyboard.

In this way, you can hear the sound of any images, for educational, artistic, or just-fun purposes!

Fully written in python, herakoi requires relatively little computational power and can be run on different on the most popular operating systems (macOS, Microsoft Windows, Linux).

Usage

1. run herakoi path_to_your_favorite_image
2. open your favorite MIDI player (e.g., if you run herakoi on an Apple computer, GarageBang is a good option)
3. have fun!

You can customize your herakoi by using the following flags:

• --notes XX YY, that will allow the pitch to span the range from the note XX and YY (with XX equal to, e.g., C4 for middle C)
• --volume ZZ, that will set lower threshold for the note volume (with ZZ in percentage)
• --switch, inverting the color-brightness mapping
