A Custom Paper-based MIDI Interface

Using computer vision and collision detection techniques Freepad further explores the development of mixed-reality interfaces for music. The result is an accessible user-definable MIDI interface for anyone with a webcam, pen and paper, which outputs MIDI notes with a velocity value based on the speed of the strike.

Members: Sungkuk Chun, Matthieu Macret, Andrew Hawryshkewich,Keechul Jung, Philippe Pasquier.
