INTRODUCTION
o People express their mental state including
thoughts and desires, all the times through facial
expressions ,vocal nuances and gestures. This is
true even when they are interacting with
machines.
o The ability to attribute mental states to others
from their behavior and to use that knowledge
to guide our own actions and predict those of
others is known as theory of mind or mind
reading.
o Existing human computers are mind blind,
oblivious to the user’s mental states and
intentions.

WHAT IS MIND READING?
.
 With a special camera, the computer observes a
person's emotions through facial expressions.
 The computer does this by observing what the team
calls "feature points" -- prominent features on the face
-- to measure movements of the head or facial
features.
 In total, there are 24 feature points the computer
watches for and 20 movements, regardless of what's
on a person's face.
 So far, the computer's database is full of actors' faces
doing their best to express joy, sorrow, anger,
confusion and other emotions.

WHY MIND READING?
 The mind reading machine is a gadget, which
enables the computer to read the mind of
human through their facial expression.
 The main objective behind this gadget is to
increase the effectiveness of the human
interaction with the computer.
 This improves the output and allows running
the application without any users input or
response. Which means the computer does not
have to wait for input from the user to run the
application.

HOW DOES IT WORK?
FUTURUSTIC HEADBAND
 The mind reading actually involves measuring the
volume and oxygen level of the blood around the
subject’s brain using the technology called functional
near-infrared spectroscopy(FNIRS).
 The user wears a sort of futuristic headband that
sends light in that spectrum into the tissues of the
head where it is absorbed by active, blood-filled
tissues.

ADVANTAGES
 The finding raises issues about
the application of such tools for
screening suspected terrorists as
well as for predicting future
dangerousness more generally.
 The day when computers will be
able to recognize the smallest
units in the English language—
the 40-odd basic sounds
(orphonemes) out of which all
words orverbalized thoughts can
be constructed.

DISADVANTAGES
 Nor is society ready to deal with the
ethical and practical problems posed by a
system that classifies and categorizes
people based on oxygen flow, genetics
and environmental factors that are
correlated as much with poverty as with
future criminality.
 In time, neuroscience may produce
reliable behavior predictions. But until
then, we should take the lessons of
science fiction to heart when deciding
how to use new
predictive techniques.

CONCLUSION
 Tufts university researches have begun a 3
year research project which, if successful, will
allow computers to respond to the brain activity
of the computer’s users.
 Users wear a futuristic looking headbands to
shine light on their foreheads and then
performs a series of increasingly difficult tasks
while the device reads what parts of the brain
are absorbing the light. That info is then
transferred to the computer and from there the
computer can adjust it’s interface and functions
to each individual.
