FFTs and force sensors

For this project I recycled some code from an earlier project. Instead of distorting the webcam image using the position of the mouse on the screen, I input from a force sensor. One can also turn the Fourier transform plot on using a switch. Below is a .gif showing the images on the screen. I also have two photos of the physical setup. I would have taken a video but my phone doesn’t have any space left 🙁

For those who are interested, I’m actually using the method I’m employing in my Processing sketch for my capstone! By cutting away high frequency channels in the frequency-domain matrix, one can extract features. Even when I’m using about 100th of the original data, one can still see some of the main features in the spacial-domain image. In my capstone, I’m using this method to get rid of noise in signals from a dark matter detector.

INTER rotated

For this week’s assignment, I originally wanted to spell ” INTERACTIVE MEDIA” and have all the letters rotate and move within the sketch frame. I ended up doing just the first five letters and made them rotate in different( increasing from the centre to the outer space) speed to create some sense of a clockwise sequence of movement.

This is a screenshot of the moving INTER:

Colorwall Update

Although I already managed to make my squares move by Wednesday, they still did not do what I initially planned so I went on trying. Eventually I managed to sort of get where I wanted, but I am glad it took me a while as the graphics that were created in the development process are actually more interesting.

Distort Word Art

I went on to the site: http://www.creativeapplications.net/processing/100-abandoned-artworks-processing/ to start finding interesting repetition patterns in animations. The videos on that page feature these subtle movements using the same shape over and over again, so I took my Snow code and essentially reworked it so that it made a simple distortion pattern across the screen. It looks like diagonal lines of dots moving around randomly, but it’s actually several columns of dots aligned together, and they move around in a synced way to give the illusion of these flowing lines. Then, I added some word art, because I thought this would be an interesting way to show a characteristic of the word “DISTORT”. By using animation and visualization, this word is kind of expressed through the piece.
