MIMICS (Multitouch Interface as a MIDI Control Suite)

Abstract

MIMICS is an acronym for Multitouch Interface as a MIDI Control Suite. Multitouch interfaces are well known for their softer learning curve compared with classical computer graphic interfaces. Therefore, its application in music interfaces may solve some of the actual limitations of hardwarebased and software-based devices. The multitouch solution is based on an optical effect called Frustrated Total Internal Reflection which is forced by using infrared light sources. This effect allows finger tracking using computer vision engines. In the thesis we describe a low-cost and affordable Hardware/Software solution for MIDI-based devices control from a functional multitouch environment. The MIMICS is presented to the user as a rear projected 30 inches screen containing a graphical interface adapted for multitouch. Implementation of several ‘ready-to-play’ applications is demonstrated that emulate classical and new MIDI control devices. The report also contains an evaluation of the results demonstrating that MIMICS is suitable for life-oriented music performances as well as for recording studio works.
