This Processing sketch is just to illustrate where I'm at with working with computer vision / blob detection. I'm able to use an IR LED in conjunction with a modified webcam (Philips SPC900NC) to create blobs of light on the screen. I then plot those out and draw the path of blobs that the computer sees. I'm working to get my enabling technologies in line now, as this isn't a finished piece. For more detailed info and to see more, visit blog.chrisroby.com.
