3. 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
behaviour 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.
4. 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.
5. 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.
6. HOW DOES IT WORK?
FUTURUSTIC HEADBAND
• The mind reading actually involves measuring
the volume and oxygen level of th 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, bloodfilled tissues.
7. 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.
8. 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.
9. 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.
