Digital Sponge Art

Kah Yen Lim, Cristina Vizán Olmedo
The idea of this project is to use the characteristics of an ordinary sponge to create drawings on touchscreen devices. The sponge can be squeezed to create thinner or thicker brushes. Additionally, different colored sides of the sponge for instance are used to map different tools (e.g. brush and eraser tool). With this technique, the general workflow should be fastened. The project itself was realized by implementing an Android app with Processing on a tablet with a capacitive touchscreen and developing a sponge recognition program written in Python. The actual recognition was done with a laptop webcam. The exchange of data between those two apps was done by implementing UDP sockets which require both devices to be connected to the internet.
