Picard has pioneered new approaches to signal processing using pattern recognition, multi-dimensional signal modeling, and computer vision. Discernible, predictable measurements of the user's actions can then be applied to user interface and software applications. Such experimental applications offer the potential for usability testing and analysis. Roz believes that much frustration among computer users can be attributed to computers' lack of 'emotional intelligence'. Handling others emotions is the job of customer service people, who follow guidelines that are effective without having to be perfect.
Emotions modulate physical communication.
They have visible signs in the face, voice, posture, and gestures. These measurable signs are the ones being investigated by the lab. Wearable computers have been invented and tested. Different experimental products and user scenarios have been tried. Alan Alda demonstrated use of the 'Twiddler' on the PBS television program 'Scientific American Frontiers' 3 years ago.
