The talk focused on The Chameleon Project, a project to produce a video art installation driven by the emotions of the audience.
The current stage of the project analyses the emotions of one member of the audience by following a set of points on that persons face to judge that persons emotional state ("mind reading technology" as they seem to like to call it). Based on the judgement of that persons emotional state the computer will choose an appropriate video response (single channel).
This is prototype 5 of 10. The final prototype they are aiming for multi-channel video of several different faces responding to the emotional states of the audience and is due to be completed in January 2010.
Will have to keep an eye on this to see the finished work.
