Transcript

  • 1.  Introduction  What is Mind Reading?  Why Mind Reading?  How does it Work?  Advantages and uses  Disadvantages and Problems  Conclusion
  • 2.  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.
  • 3.  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.
  • 4.  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.
  • 5.  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”.
  • 6. 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.
  • 7.  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.
  • 8.  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.
  • 9. Blood Volume Pulse It is measured by process called photoplethysmography. It produce a graph indicating blood flow through the extremities.
  • 10.  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.
  • 11.  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
  • 12.  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.
