Mind reading computer
- 2. CONTENTS • Introduction • What is mind reading..? • Why mind reading..? • How does it works..? • Advantages • Disadvantages • Applications • Conclusion
- 3. INTRODUCTION • People express their mental states,including emotions,thoughts & 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..? • The team in the Computer Laboratory at the University of Cambridge has developed mind reading computers that implement a computational model of mind reading to infer mental states of people from their facial signals. • Using a digital video camera, the mind reading computer system analyzes a person’s underlying mental state, such as whether he/she is agreeing or disagreeing, interested or bored, thinking or confused.
- 5. • 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. • For example, a combination of a head nod, with a smile and eyebrows raised might mean interest.
- 6. WHY MIND READING..? • The Mind Reading Computer system presents information about your mental state as easily as a keyboard and mouse present a text & 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 & learning system.
- 7. • The mind reading computer system may also be used to monitor & suggest improvements in human-human interaction. • To implement this system in cars, to detect driver’s mental states such as drowsiness, distraction and anger.
- 8. HOW DOES IT WORKS..? • The mind reading actually involves measuring the volume and oxygen level of the blood around the subject’s using technique 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. Futuristichead band
- 9. WEB SEARCH • For the first test of sensors, scientists trained the program to recognize 6 words including “go”, “left” and “right” – 10 numbers. • Then researchers put the letters of the alphabet into a matrix with each column and row labelled 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.
- 10. ADVANTAGES • Can read minds • Help paralytic patients • Help handicapped people • Help comma patients • Help people cannot speak • Can be used for military field & sting operations • Can be combined with consoles & used for mind gaming, robotics, etc. • Eliminate the capability to lie • Prevent from terror
- 11. DISADVANTAGES • Breach in privacy • Can extract, through an individual, an important, secure & confidential information of individual, state or even a country • Can't make good lies • Risk of being used in bad way • Expensive
- 12. APPLICATIONS • A mind controlled wheel chair developed from the University of Electro- Communications in Japan. • Brain-Computer Typing machine by thinking about left and right head movement user can control the virtual keyboard.
- 13. • In spell checking. • In interactive gaming areas. • For controlling a mechatronic device. • Interactions within a virtual reality environment. • Communication by thoughts.
- 14. CONCLUSION • Some equipment are used to gather data & then analyzed. To use those data for further prediction is known as “Theory of mind reading”. • 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.
- 15. • Hence if we get 100% accuracy these computers may find various applications in many fields of electronics where we have very less time to react. • IBM says Mind reading is no longer science fiction we will have Mind- Reading Computers within 5 years.
