Live video color tracking Live camera input and color tracking utilize jit.findbounds object in Max/MSP/Jitter programming environment. The method can be used to find the bounds of a specified color on incoming image matrix. An object in the installation (the tenth object), painted in distinctive color, can be tracked this way. Its coordinates may control a grain synthesizer that is used to make the buzzing sound. Although there may be some interference of the tracking caused by the viewers (they may wear the same color blouse as the tracked object, for instance) or by the video projection, which will overlay part of the tracked object), any disruption will not profoundly change the meaning and the reception of the project.
Capacitive Sensor & Arduino Technically, the interaction with the use of conductive ink is possible by utilizing a microcontroller, namely Arduino, which deals with the incoming data. The code in Arduino uses external library called CapacitiveSensor by Paul Badger. It is available at Arduino Playground (http://playground. arduino.cc//Main/CapacitiveSensor?from=Main.CapSense). An Arduino board holds this code in its memory together with some extra code needed for serial communication, which allows for sending the received input to another program on the computer, namely Max/MSP/Jitter. The latter deals with playing of the sounds and video. Capacitive sensor needs some wiring and resistors to process the electric impulses on the input. The CapacitiveSensor class uses one digital pin from Arduino as receive pin, 41
