Technology & Emotions


This is an interesting TED talk by Professor Rosalind Picard, who describes how scientists have developed equipment to measure emotional arousal in people during the course of the day, in order to gain insights into our emotional responses to events in our lives.

This technology measures skin conductance, also known as galvanic skin responses (GSR), or electrodermal activity (EDA), which is a measure of activation of the sympathetic nervous system. When the sympathetic nervous system is activated, during higher stages or arousal, this can be detected in the skin.

They aim to use this technology to assist people with autism read the emotional expressions of others using technology. There are also some quite surprising and amusing other results shown in this talk!

Here is the YouTube description of the presentation:

"Professor Rosalind W. Picard, ScD is founder and director of the Affective Computing research group at the MIT Media Lab, co-director of the Things That Think consortium, and leader of the new and growing Autism & Communication Technology Initiative at MIT. In April 2009 she co-founded Affectiva, Inc., where she serves as chairman and chief scientist.

Picard holds a bachelor's degree in electrical engineering with highest honors from the Georgia Institute of Technology, and master's and doctoral degrees, both in electrical engineering and computer science, from MIT. Prior to completing her doctorate at MIT, she was a member of the technical staff at AT&T Bell Laboratories. In 1991 she joined the MIT Media Lab faculty, where she became internationally known for content-based retrieval research, for creating new tools such as the Photobook system, and for pioneering methods of automated search and annotation in digital video.

She is the author of the award-winning book Affective Computing, which was instrumental in starting a new field by that name. She has authored 200 scientific articles and chapters and also holds multiple patents. In 2005, she was honored as a Fellow of the IEEE."
