The document discusses a seminar presentation on mind reading computers. It begins with an introduction on how people express mental states through facial expressions and gestures. It then discusses what mind reading is, how it works using sensors to measure blood oxygen levels in the brain, and the process which involves facial detection and emotional classification techniques. Applications are discussed including using it to help paralyzed people communicate and potential issues around privacy breaches. It concludes that research is underway to allow computers to respond to brain activity.

3. INTRODUCTION
 People express their mental states, including emotions, thoughts, and 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?
 Drawing inspiration from psychology, computer vision and machine learning has
developed mind reading machines computer.
 Using a digital video camera, the mind reading computer system analyzes a
person’s facial expressions in real time and infers that person’s underlying mental
state.
 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 NEVEN VISION identifies 24 feature points on the face and tracks
them in real time.

5. WHY MIND READING?
 The mind reading computer system presents information about your mental state
easily as a keyboard and a mouse present text and commands. Imagine a future
where we are surrounded with mobile phones, cars and online services that can read
our mind and react to our mood.
 We are also looking at the use of mind reading to support on-line shopping and
learning systems.
 The mind reading computer system may also be used to monitor and suggest
improvements in human-human interaction.

6. HOW DOES IT WORK?
Futuristic Headband
 The mind reading actually involves measuring the volume and oxygen level of the
blood around the subject’s brain using technology called functional near-infrared
spectroscopy(FNIRS).

7. CONTINUED……
 Measuring mental workload, frustration and distraction is typically limited to
qualitatively observing computer users.
 A computer program which can read silently spoken words by analyzing nerve
signals in our mouths and throats, has been developed by NASA.
 Biological signals arise when reading or speaking to oneself with or without actual
lip or facial movement.
 In a 2011 study, researchers translates brain waves into the movie clips people were
watching at the time.
 In 2014, two scientists transmitted thoughts to each other using a brain-to-brain
link. And other studies have shown that computers can “see” what people are
dreaming about, using only their brain activity.

9. PROCESS OF MIND READING COMPUTER

10. WEB SEARCH
 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 alphabets into 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.

11. TECHNIQUES
 Facial Effect Detection
It is done using hidden Markov Model, Neural Network Model or Active Appearance
Model.

12. CONTINUED……
 Emotional Classification
Classification by Paul Ekman Anger, Fear, Happiness, Disgust, Sadness, Surprise.

13. CONTINUED…..
 Facial Electromyography
It is used to measure electrical activity of the facial muscles. Muscles used are
“corrugator supercilii muscle” and others.

14. CONTINUED…..
 Galvanic Skin Response
It is a measure of Skin conductivity, which is dependent on how moist the skin is.

15. CONTINUED…..
 Blood Volume Pulse
a) It is measured by process called photoplethysmography.
b) It produces a graph indicating blood flow through the extremities.

16. APPLICATIONS
 Mind-Reading Computers could ‘save your life’.
 Control robots by brain power.
 Emergency
 Mind-Reading Computer that could communicate with coma patient.
 A mind controlled wheel chair developed from the university of electro-
communications in japan.

17. ADVANTAGES AND USES
 Can read minds.
 Help paralytic patients.
 Help comma patients.
 Help people who cant speak.
 Can be used for military field and sting operation.
 Eliminate the capability of lie.

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

19. CONCLUSION
 Tufts university researchers have begun a 3 year research project which, if
successful, will allow computers to respond to the brain activity of the computer’s
users.
 IBM says Mind reading is no longer science fiction we will have mind-reading
computers with in 5 years.
