No it can't read minds in the literal sense, but it's probably still better than a polygraph machine.
say that only a small fraction of human communication comes from words; about
60% is body language and about 30% is tone. The irony is that most of us are
probably not able to pick up on these subliminal messages very well. That might
be why Rana El Kaliouby, an MIT grad student, decided to develop the special
software used in the Emotional Social Intelligence Prosthetic, which is a
device that helps people interpret body language and facial expressions. The
device, upon detecting boredom/inattention in the listener, will vibrate to
alert the user.
"This software interprets emotions based on body language
and facial expressions which are captured via a wearable computer/video camera
"The video data is used to decide whether the listener is
agreeing, disagreeing, thinking, concentrating, interested, or unsure."
"To train her software El Kaliouby used video of actors able
to very clearly define an emotion on film. Now, the system is able to pick out
the right emotion 90% of the time when using actor footage, and 64% of the time
with video clips of everyday people."
The rate of accuracy is expected to improve greatly as
more footage is recorded into the database. Such a device would be invaluable
to autistics, people who suffer from autism, which is a psychological condition
characterized by deficits in social interaction and communication, public
speakers, including bad profs, or anyone who sees the value in being able to
