Digital Graffiti – A Subculture Conquers Interactive Worlds
Finally I delivered my thesis project I did in cooperation with Less Rain. The subject was »Digital Graffiti – A Subculture Conquers Interactive Worlds« and it’s all about experimenting with different input devices for a physical, digital graffiti installation. The result is an Adobe AIR application using either the computer mouse, the Nintendo Wiimote or »VandalSpray« to paint digital canvases. VandalSpray is a digital spray can specifically designed for this purpose. It implements the attributes of a real spray can or at least trys to achieve them as natural as possible. Except a turnable bottom for changing the color, VandalSpray has no other interfacing elements than its real counterpart and therefore you don’t have to learn and explore the functionality first, because you intuitively know how to use it.
VandalSpray features includes:
- exchangeable caps
- color display
- digital valve system to vary the amount of »paint« coming out of the cap
- different colors
The spray can is built upon the Arduino platform and uses different sensors and electronic modules like a RFID reader, a super bright RGB LED, a Rotary Encoder, a Bluetooth module, a force sensitive resitor (FSR) and loads of wires and solder to implement the desired behavior. For tracking the spray can I use a Wiimote and the WiiFlash ActionScript 3 library and server, but this could also be replaced by a standard webcam and an adequate tracking implementation.
Because I didn’t want to put some kind of speaker in the spray can (there was no space left anyway) the spray sound is generated from the AIR app and output on the speakers of the notebook.
