Your Computer May Know When You're Smiling

Did you smile? Now your computer can answer that question: MIT’s Media Lab is developing technology whereby your computer, with the help of a webcam, can read?facial movements to analyze whether you’re smiling. The technology was first developed to help autistic individuals with expression recognition. Daniel McDuff, the researcher in charge, is collecting data for this project. If you have a webcam, you can try the demo out here — where, after watching a short commercial, you can see a graph of whether your face expressed that the commercial was funny. Or not.
