I used a stretch sensor and some wire taped around my chest to create a visual representation of my breathing patterns. Using Processing, I had the size of an ellipse change depending on the stretch sensor’s reading. More importantly, I leave past readings on the screen, slowly fading out, to give the viewer (and myself) a better representation of the movement and speed of my breathing.
Although not a traditional graph, I tried to create a visualization that indicates the recently past positions of the reading, in this case, my chest circumference or my breathing patterns. I liked the idea of representing this action in the form of an expanding body (which is, after all, what I am measuring), and the end result reminds me of the rings found in the cross-section of cut trees – themselves a much more permanent sort of representation of the past.
One thing I’d like to fix is to make the circle smaller when my chest circumference is at its minimal – this would make the visualization’s movements even more granular and would better amplify the already surprisingly organic movement.
