Mind Reading Computer

  1. 1. PRESENTED BY....... MAHIM MALLICK NSEC,EIE(3rd year) ROLL NO:- 21
  3. 3. • The ability to attribute mental states to others from their behaviour and to use that knowledge to guide our own actions and predict those of others is known as theory of mind or Mind Reading.OR Some equipment are used to gather data & then analyzed. To use those data for further prediction is known as “Theory of mind reading”. • People express their mental states including thoughts and desire, all the time through facial expressions, vocal nuances and gestures. This is true even when they are interacting with machines. • Existing human-computer interfaces are mind-blind, oblivious to the user’s mental states and intentions. • Even they do not take the initiative, like the now retired Microsoft Paperclip, they are often misguided and irrelevant and simply frustrate the user. • Mind reading machine is co-ordination of human psychology & computer techniques.
  4. 4.  Drawing inspiration from psychology, computer vision and machine learning has developed mind reading machine computers.  Using a digital video camera, the mindreading computer system analyses 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 expressions and head gestures occurring in real time.  Software from Nevenvision identifies 24 feature points on the face and tracks them in real time.  The relationship between observable head and facial displays and the corresponding hidden mental states over time is modeled using Dynamic Bayesian Networks.
  5. 5. 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. 6. 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). • Measuring mental workload, frustration and distraction is typically limited to qualitatively observing computer users.  The user wears a futuristic head band that sends light in that spectrum into the tissues of the head where it is absorbed by active, blood filled tissues.
  7. 7.  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.  The results are often compared to an MRI, but can be gathered with lightweight, non-invasive equipment.  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.  Wearing the FNIRS sensor, experimental subjects were asked to count the number of squares on a rotating onscreen cube and to perform other tasks.  Measuring mental workload, frustration and distraction is typically limited to qualitatively observing computer users.  Preliminary results show that using botanized sensors.
  8. 8.  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.  This prototype mind reading wheel chair developed from the University of Electro communications in Japan.  A little from the Brain-Computer Typing machine, this thing works by mapping brain waves when you think about moving left, right, forward or back and then assigns that to a wheelchair.  The system could send command to rovers on other planets, help injured astronauts control machines, or aid disabled people.
  9. 9. It is done using hidden Markov Model, Neural Network Model or Active Appearance Model. Classification by Paul Ekman Anger, Fear, Happiness, Disgust, Sadness, Surprise.
  10. 10. Facial Electromyography • It is used to measure electrical activity of the facial muscles. Muscles used are “corrugators supercilious muscle” and others. Galvanic Skin Response It is a measure of Skin conductivity, which is dependent on how moist the skin is.
  11. 11. Blood Volume Pulse a) It is measured by process called photoplethysmography. b) It produces a graph indicating blood flow through the extremities. Robot control • Now there are so many type robot which is controlled by mind
  12. 12. 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.
  13. 13. • TAPPING BRAINS FOR FUTURE CRIMES  Using computer algorithms and functional magnetic resonance imaging (FMRI), the scientists were able to determine with 70percent accuracy.  Individual brain differs, so scientists need to study a subject's pattern before they can train a computer to identify those patterns or make predictions.  In Dec 19,2006 the issue of The Economist, an article questioned the scientific validity of the notion of free will: Individual with particular congenital genetic characteristics are predisposed, if not predestined, to violence.  Max Planck Institute, neuroscience and bioscience are not at a point where we can reliably predict human behaviour.  Nor is society deal with the ethical and practical problems posed by a system that classifies and categorizes people based on oxygen flow, genetics and environmental factors that are correlated as much as poverty as with future criminality.  In time, neuroscience may produce reliable behaviour predictions. But until then, we should take the lessons of science fiction to heart when deciding how to use new predictive techniques.
  14. 14. • Tufts university researches have begun a 3 year research project which, if successful, will allow computers to respond to the brain activity of the computer’s users. • Users wear a futuristic looking headbands to shine light on their foreheads and then performs 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.
