Bubblicious is an interactive installation which got created in the Summer Term 2013 at the study course Interactive Media Design of the University of Applied Sciences Darmstadt. The courses in which it has been built are "Interactive Installations" by Martin Schuster from MESO and "Physical Interfaces" by Alexander Stefas.
The installation recognizes at which place persons are moving and creates bubbles at the detected location. This is done by giving more power to the computer fans.
The movement detection is done by Processing. A webcam delivers the video footage, Processing saves the last frame and the current frame and looks for different pixels. The image is divided in columns. If there is enough movement in one of the columns, the according fan is activated.
The fans are connected via Arduino over PWM Pins, so it is possible to steer for every single one.
