Touch Designer and Computer Vision with Noel Acosta @ The Tiny Bar
Unlock the creative potential of Computer Vision and Touch Designer in this introductory session led by Noel Acosta (Nono, Intruder NTRDR). Originally presented as part of the Kislap open-learn series, this course provides a fascinating overview of how computer vision concepts can be integrated with the powerful visual programming language Touch Designer, specifically for innovative audio-visual performances.
Join Nono, a programmer since the early 90s and a long-time figure in the electronic music scene, as he shares his unique perspective blending technical expertise with a passion for live AV experiences. You’ll gain insights into:
- Fundamentals of Computer Vision: Understand the basic principles of computer vision, its current applications (like face detection), and early forms like Optical Character Recognition (OCR).
- Hardware and Software for Computer Vision: Learn about the essential hardware (cameras) and freely available software libraries like OpenCV and MediaPipe.
- Practical Demonstrations (Conceptual): Witness demonstrations of color and color area detection using Python and OpenCV, illustrating the potential for interactive installations and performances.
- Introduction to Touch Designer: Discover Touch Designer as a node-based visual programming language with Python scripting capabilities.
- Creative Integration: Explore compelling examples of how data from specialized cameras (like Leap Motion) and even smartphone cameras can be used within Touch Designer to control audio and visual elements in real-time:
- Using Leap Motion for gesture-based control of sound parameters.
- Wireless control of visuals via iPhone feature detection and OSC.
- Potential integration with Android face detection.
- Theremin emulation using Leap Motion pinch gestures.
- Potential Applications: Get inspired by the vast possibilities for combining computer vision and Touch Designer in live performances, interactive installations, and more.
While this session encountered some technical limitations during the live demonstrations, it provides a valuable foundational understanding and sparks inspiration for further exploration. If you’re interested in the cutting edge of audio-visual technology and want to discover how movement and gesture can drive your creative projects, this free introductory course is a perfect starting point.
