Description
With this Theremin-inspired instrument you can control sound by moving your finger in front of the camera. Assign sound parameters to the three spatial axes (x, y and z). Then hold something colorful or wear it on your fingertip (e.g. a thimble, a pencil or a bottle cap). The Theremin will follow it so that you can change pitch, gain, vibrato, and flanger parameters with a simple gesture. You can also record any sound that you wish to control with your finger. Moreover, change background color, select range and pitch collection.

Fun for a while. Maybe as a controller it could be used also for something else.

Everything was chill until I started recording myself making stupid sounds. Gods above man, what hell hath thou wrought?

Cool concept, applause to the developer. But it is glitchy. My biggest gripe? Massive headache within the first minute of using it, due to the powerful IR light being emitted from the phone. IR light is not visible to the human eye, but is nonetheless harmful to vision.

Headline this is not true application random number this application generates random number to trick users this is interactive I covered the camera using black pads on the pointer keeps moving waste of storage space I tried it many times and still not working your last chance use hand tracking instead track hand movements

Good idea, but in its current state it works like an alpha version, a work in progress. (Btw because of tone gradation it cannot be called a theremin.) Keep working on it!

Too glitchy to be useful, may have been reacting to soundproof walls in the background, but it couldn't hold a note and just jumped all around the spectrum.
