For this lab, I wanted to simulate the experience of cleaning the ground using a water sprayer (a common event on Stanford campus). I basically used the accelerometer, white noise, and cascading high and low pass filters. I decided on this idea because I thought that there was a nice relationship between hearing filters work at different frequencies and hearing jets of water hitting different surfaces at different angles. Originally I wanted to keep the sound mappings entirely symmetric, but after I noticed that a size-4 cascading low-pass filter seemed more restritive and uninteresting compared a size-4 cascading high-pass filter, I decided that a little assymmetry was okay, and used a size-4 cascading HPF and a size-2 cascading LPF.
Here you can see that tilting horizontally changes one filter's MIDI frequency, while tilting vertically changes the other filter's. Since in real life if you jerk a hose you accidentally might spray someone and make him angry, I wanted to play a stern warning like "Hey!", "Watch where you're aiming that!", and "You ruined my girlfriend's favorite shirt!" every time you jerked the accelerometer. But I ran into trouble getting pd to locate and load my uploaded wave files, and so I resorted to the default sound snippets. My graphics is not that exciting either, but hopefully it still gives the user some cues regarding tilting and jerking.
