MIND READING COMPUTER
SUBMITTED BY:

2.  Introduction
 What is Mind Reading?
 Why Mind Reading?
 How does it Work?
 Advantages and uses
 Disadvantages and Problems
 Conclusion

3.  People express their mental state, including emotions, thoughts and
desires, all time through facial expression, vocal nuances and
gesture.
 Mind reading machine is co-ordination of human psychology and
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.  The team in the Computer Laboratory at the University of Cambridge has
developed Mind Reading Machines-Computers that implement computational model
of Mind Reading to infer mental states of people from their facial signal.
 Prior Knowledge of how particular mental states are expressed in the face is
combined with analysis of facial expression and head gestures occurring in real
time.
 Software from Nevenvision identifies 24 feature point on the face and tracks
them in real time.
 For example, a combination of head node, with a smile and eyebrows raised might
mean interest.

6.  The Mind reading Computer system Present information about
your mental state as easily as a keyboard and mouse present a
text and 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 and learning system.

7. The mind-reading computer system may also be used to monitor and suggest
improvements in human-human interaction.
The Affective Computing Group at the MIT Media Laboratory is developing an
emotional-social intelligence prosthesis that explores new technologies to
augment and improve people’s social interactions
and communication skills.
To implement this system in cars to detect
driver mental states such as drowsiness,
distraction and anger.

8.  The mind reading actually involves
measuring the volume and oxygen level
of the blood around the subject’s brain
using tech. 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.  For the first test of sensors, scientists
trained the program to recognize six
words-including ”go", "left” and “right” -
10 numbers.
 Then researchers put the letters of the
alphabet in to a matrix with each column
and row labeled 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”.

11.  It deals with anatomy and molecular biology of neurons.
 A neuron is a nerve cell that is the basic building block of
the nervous system. Neurons are specialized to transmit
information throughout the body.
 It is done by measuring oxygen level of blood using
FNIRS.

12.  Facial effect detection
It is done using hidden Markov Model, Neural Network processing or active
appearance model.
 Emotional Classification
Classification by Paul Ekman Anger, Fear, Happiness, Disgust, Sadness, Surprise.

13. It is used to measure electrical activity of the facial Muscles. Muscles
used are ”corruguator supercilii muscle” and others.
It is a measure of Skin conductivity, Which is dependent on how moist
the skin is.

14. It is measured by process called
photoplethysmography.
It produces a graph indicating blood flow
through the extremities.

15.  Can read minds.
 Help paralytic patients.
 Help Handicapped people.
 Help Comma patients.
 Help people who cant speak.
 Can be used for military purposes & sting operations.
 Can be combined with consoles & used for mind gaming, robotics & stuff.
 Eliminate the capability to lie.

16.  Breach in privacy.
 Can extract, through an individual, an important, secure
& confidential information of individual, state or even a
country.
 If developed or used by sinners, can be highly
dangerous.
 Eavesdropping.
 No way to neutralize this technology.

17.  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.
 Users wear futuristic-looking head bands to shine light on their
foreheads, and then perform 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.
