Processing wiimote analysis – Prototype idea

I made some applications in Processing to further investigate the wiimotes, and how they react to different movements. I’m using all of the indications of movement possible with the wiimote (except for the IR camera, for freedom of movement); Pitch, Roll, Yaw, overall Acceleration (these are calculated by OSCulator) and also the raw X,Y,Z accelerations.

While waving the wiimotes around I noticed some things. If you’re making round movements, the graphs become a fluent curve, almost a sinewave sometimes. If you’re moving really wildly, it gets closer to a sawtooth or pulse wave. This made me thinking that maybe the most direct connection between your movements and the sound that you produce, is through these waves that you draw. The “buffer” above is 500 samples long. In a second of “CD quality” sound there go 44100 samples. So if you repeat one of these waveforms 88,2 times per second in an oscillator, you undoubtedly would get a very “own” sound.

This is definitely something I’m going to explore, I can barely wait!
