mind reading computer

  1. 1. Narayani college for professional studies Presentation on information and technology (mind-reading computer) Presented by-Sabin Tripathi
  2. 2. What is information technology? “Information Technology is the use of hardware, software, services, and supporting infrastructure to manage and deliver information.”
  3. 3. Mind-Reading Computer Introduction Drawing inspiration from psychology, computer vision and machine learning, the team in the Computer Laboratory at the University of Cambridge has developed mind-reading machines - computers that implement a computational model of mind-reading to infer mental states of people from their facial signals. The goal is to enhance human-computer interaction through empathic responses, to improve the productivity of the user and to enable applications to initiate interactions with and on behalf of the user, without waiting for explicit input from that user.
  4. 4. Why mind reading?
  5. 5. Why mind reading? The mind-reading computer system presents information about your mental state as easily as a keyboard and mouse present text and commands. Imagine a future where we are surrounded with mobile phones, cars and online services that can read our minds and react to our moods. How would that change our use of technology and our lives? This system also can be used in cars to detect driver mental states such as drowsiness, distraction and anger. Imagine writing an email without typing. You just have to think and your words appear on the screen.
  6. 6. Why mind reading… • Many disabled people are living in this world. Although they are disable from outside they can be mentally well from inside but they cant share their feelings infront of us. So this computer can be very helpful for such people to share their feelings and emotion.
  7. 7. How does it work? Futuristic headband
  8. 8. How does it work… • Different sensors are fixed all around the futuristic headband which measures the blood pressure ,impulses, temperature of brain using technology called functional near-infrared spectroscopy (fnirs) and sends the information to the computer which helps to find whether the person is in happy mood or aggressive mood.
  9. 9. How does it work…. • Software from Nevenvision identifies 24 feature points on the face and tracks them in real time. Movement, shape and colour are then analyzed to identify gestures like a smile or eyebrows being raised. Combinations of these occurring over time indicate mental states. For example, a combination of a head nod, with a smile and eyebrows raised might mean interest.
  10. 10. How does it work… • 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. • 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, such as whether he or she is agreeing or disagreeing, interested or bored, thinking or confused.
