9.02:    Kick-off

12.02:    Emotions and their display on faces

  • introduction: goal of the course, assesment, way of working
  • we do the pre-test of the Japanese designs
  • emotions: some questions to ask
  • emotions: physiology, mental state, display
  • quick course about modelling facial expressions
  • CharToon demos,
  1. Do the Japanese research experiment, if you have not done it yet before. You may need to try at different times of the day to have fast contact.
  2. Skecth a few (at least 4) heads on paper, not too realistic but expressive, man/woman, and for each a happy and a sad version. Scan your designs digitally as images.
    Use file names as: yourname_headnumber_emotion where emotion is neutral, happy or sad
  3. Download and install the CharToon sw on your laptop/PC. I am not sure if it runs on MacOs - just give a try.
    You need Java installed to run it. Test if you can start the sw. If you have problems, send a mail.
  4. Download the into paper and the documentation.
  5. For next class bring along your laptop, or if you do not have one, the designs on a stick.

  • happy and sad expressions according to Ekman - and here is a masked expression

Assignments for Friday:
  1. at least 2 faces, man-woman, each with happy/sad/neutral expression should be scanned to 600x800 pixel image, ready to be viewed
  2. make a design description of the best 2 faces (man/woman) by layers, what will be moving of the features
