The document describes research into developing "mind reading" computers that can infer users' mental states from facial expressions and other inputs. Researchers at the University of Cambridge have created a system that uses sensors and software to track 24 facial feature points in real time and identify expressions associated with mental states like interest or engagement. Tufts University is also working on a project using headbands that detect blood flow in the brain to allow users to silently control computers with their thoughts. The technology could help people with disabilities but also raises privacy and security concerns if it were used to extract confidential information without consent.

2. Introduction
What isMind Reading?
Why Mind Reading?
How does itWork?
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 Lab 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.

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.

The mind-reading computer system may also be used to monitor and
suggest improvements in human-human interaction.
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.

10. 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”.

17. Can read minds.
Help Handicapped people.
Help Comma patients.
Help people who cant speak.
Can be used for military purposes & sting operations.
Eliminate the capability to lie.

18. 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.

19. 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.
