The group has now tested both the Neurosky, Eye Tracker and Face Reader technologies. The FaceReader shows a range of emotions that the user experiences whilst being filmed. Problems were encountered with calibrating the software so that it measured neutral when the participant's expression was neutral. This was best evidenced by myself, when I used it the emotion that was read was 'angry' a lot of the time!
The FaceReader analyses a section of a recording of a person's face, showing what emotions they are currently displaying. However, it does not show how emotionally engaged a user is, which is want is more important for what we are trying to measure.
Tomorrow we hope to look at the technologies and make a decision as to which best serves our needs.
