post reading emotions

February 13th, 2008

In different emotional states, we direct our gaze to different parts of the face first – Using eye tracking – we look at eyebrows/brow area first – happiness we look to the mouth. Could use this to advantage – could abstract the imagery real time. When healthy people look at faces, they spend a lot of time looking at the eyes and the mouth, as shown in the figure below. People with damage to the amygdala, with agenesis of the corpus callosum, and with autism, all look at faces abnormally.


using eye tracking to work out how we view a face to make sense fo the expression


reworking Paul Ekmans FACS database. Bringing particular features of the faces forward – does emotion still get read? Is it stronger? How much can ou abstract the image before the emotional expression gets lost?
