The document discusses the development and functionality of mind reading computers, which analyze facial expressions and gestures to infer a person's mental state. Advantages include aiding disabled individuals and improving interactions, while disadvantages encompass privacy concerns and potential misuse. Future applications may extend to fields like online shopping and automotive safety, with projections for practical implementation within five years.

2. CONTENTS
• Introduction
• What is mind reading..?
• Why mind reading..?
• How does it works..?
• Advantages
• Disadvantages
• Applications
• Conclusion

3. INTRODUCTION
• People express their mental states,including
emotions,thoughts & desires,all the time
through facial expressions, vocal nuances and
gestures.
• Mind reading machine is co-ordination of
human psychology & computer techniques.
• Some equipment are used to gather data &
then analyzed. To use those data for further
prediction is known as “Theory of mind
reading”.

4. WHAT IS MIND READING..?
• The team in the Computer Laboratory at the
University of Cambridge has developed mind reading
computers that implement a computational model of
mind reading to infer mental states of people from
their facial signals.
• Using a digital video camera, the mind reading
computer system analyzes a person’s underlying
mental state, such as whether he/she is agreeing or
disagreeing, interested or bored, thinking or
confused.

5. • Prior knowledge of how particular mental
states are expressed in the face is combined
with analysis of facial expressions and head
gestures occurring in real time.
• Software from NEVENVISION identifies 24
feature points on the face and tracks them
in real time.
• For example, a combination of a head nod,
with a smile and eyebrows raised might
mean interest.

6. WHY MIND READING..?
• The Mind Reading Computer system presents
information about your mental state as easily
as a keyboard and mouse present a text &
commands.
• Current project in Cambridge are considering
further input such as body posture and
gesture to improve the inference.
• We also looking at the use of mind reading to
support online shopping & learning system.

7. • The mind reading computer system
may also be used to monitor & suggest
improvements in human-human
interaction.
• To implement this system in cars, to
detect driver’s mental states such as
drowsiness, distraction and anger.

8. HOW DOES IT WORKS..?
• The mind reading actually
involves measuring the
volume and oxygen level of
the blood around the
subject’s using technique
called functional near
infrared
spectroscopy(FNIRS).
• The user wears a sort of
futuristic head band that
send light in that spectrum in
to the tissues of the head
where it is absorbed by
active , blood filled tissues.

9. WEB SEARCH
• For the first test of sensors, scientists trained
the program to recognize 6 words including
“go”, “left” and “right” – 10 numbers.
• Then researchers put the letters of the
alphabet into a matrix with each column and
row labelled with a single digit number.
• These were used to silently spell “NASA” into a
web search engine using program.
• This proved we could browse the web without
touching a keyboard.

10. ADVANTAGES
• Can read minds
• Help paralytic patients
• Help handicapped people
• Help comma patients
• Help people cannot speak
• Can be used for military field & sting operations
• Can be combined with consoles & used for mind
gaming, robotics, etc.
• Eliminate the capability to lie
• Prevent from terror

11. DISADVANTAGES
• Breach in privacy
• Can extract, through an individual, an
important, secure & confidential
information of individual, state or even a
country
• Can't make good lies
• Risk of being used in bad way
• Expensive

12. APPLICATIONS
• A mind controlled wheel
chair developed from the
University of Electro-
Communications in Japan.
• Brain-Computer Typing
machine by thinking about
left and right head
movement user can control
the virtual keyboard.

13. • In spell checking.
• In interactive gaming areas.
• For controlling a
mechatronic device.
• Interactions within a virtual
reality environment.
• Communication by
thoughts.

14. CONCLUSION
• Some equipment are used to gather data & then
analyzed. To use those data for further
prediction is known as “Theory of mind
reading”.
• Tufts University researchers have begun a three-
year research project which, if successful, will
allow computers to respond to the brain activity
of the computer's user.

15. • Hence if we get 100% accuracy these
computers may find various
applications in many fields of
electronics where we have very less
time to react.
• IBM says Mind reading is no longer
science fiction we will have Mind-
Reading Computers within 5 years.
