Software reads faces for comprehension

   July 7/14, 2008
Software that automatically recognizes facial expressions measures how difficult people perceive a lecture to be and the pace they'd prefer the material to be delivered. A prototype system automatically adjusts the speed of a video presentation based on the viewer's facial expressions.

The system promises to tailor learning materials to individual students, provide lecturers with feedback and improve human-robot interaction.
