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.
 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.

5.  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.

6.  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”.

7. The results are often compared to an
MRI, but can be gathered with
lightweight, noninvasive equipment.
Wearing the FNIRS sensor,
experimental subjects were asked to
count the number of squares on a
rotating onscreen cube and to perform
other tasks.

8.  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.

9.  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.

10. Blood Volume Pulse
It is measured by process called
photoplethysmography.
It produce a graph indicating blood
flow through the extremities.

11.  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.

12.  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

13.  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.
