The Interactive Development Environment: bringing the creative process to the art of coding.
TIDE is an attempt to integrate the celebrated traditions of the artistic process and the often sterile environment of programming. The dialogue of creative processes exists in the process of coding as frustration: debugging, fixing, and fidgeting over details until the programmer and program are unified. TIDE attempts to turn this frustration into the exhilaration of dialogue between artist and art.
The environment uses a Kinect to find and track gestures that correspond to values. Processing code is written with these values and saved in a .txt file. The result code creates a simple shape on screen. I want to expand this project to be able to recognize more gestures and patterns, allowing for much more complicated systems to be implemented. Ironically, I found the process of implementing and testing this project generating the very frustration and sterility I was trying to eradicate with the intuitive, free flowing motions I could get with the Kinect.
