## What is Air Theremin?

Air Theremin is a digital instrument played in the air using a webcam or phone camera. A modern interpretation of the classic Theremin, it allows users to generate sound through hand movements. It works on both computers and phones. The basic principle relies on converting camera-detected movements into sound parameters.

## Control with Hand Movements

To use Air Theremin, simply move your hands toward the camera. Spread your hands to adjust volume, raise them to change pitch, lean back to soften the tone, or bring your palms together to mute the sound. This method works seamlessly with both computer and phone cameras.

## Gyro Control on Phones

If using a phone, you can control it by tilting the device instead of hand movements. Tilting left-right adjusts volume, while forward-back sets the pitch. The sound range stays within the frame; tilting the marker outside cuts the sound. This feature utilizes the phone's gyro sensor.

## Alternative Mouse Control

For devices without a camera or gyro sensor, Air Theremin can be controlled using a mouse. Mouse movements replace hand or phone movements, offering a similar experience. This feature ensures compatibility across all types of devices and enhances accessibility.

## Start and Calibration

To start using Air Theremin, simply press the 'START' button. If using a phone, the device automatically calibrates to your grip when held steady. This process ensures a personalized experience tailored to the user.

## Ease of Use

Air Theremin stands out with its user-friendly interface and simple control mechanisms. Designed to be accessible to everyone, it requires no prior knowledge or musical skills. This feature appeals to a broad audience.

## Technological Infrastructure

Air Theremin uses camera and gyro sensors to produce real-time sound. This technological infrastructure instantly converts user movements into sound, offering an interactive experience. Additionally, mouse control has been added to increase accessibility.

## Innovative Music Experience

Air Theremin offers a music experience beyond traditional instruments. As a fun and innovative tool, it aims to unleash users' creativity. Such tools serve as inspiring examples of how music is evolving in the digital age.
