0.1 Design concept

Overall goal

In our project, we attempted to simulate a theremin using a typical webcam. Just as a theremin is controlled only by 2 values, our virtual theremin is also controlled by two values based on image processing techniques.

By tracking some object, the virtual theremin can determine x-position, y-position, angle, and size of that object in the image that a camera returns. Pitch and volume can be controlled by any two of these values.

The two normalized values representing pitch and volume will be passed to audio control which will then set volume and pitch to correspond to the values given by object tracking.

Implementation methodology

Object detection

Real time audio

Specification goals

• Have multiple sounds possible
• Have multiple object usage possible
• Real-time video and audio output
• Steady object holds pitch and volume to within +/- 5% of normalized range
