- 2. ACKNOWLEDGEMENT I owe a great many thanks to a great many people who helped and supported me during the writing of this seminar report. I would like to take this opportunity to extend profound gratitude to Mr. Sukumar Roy, H.O.D of bio-medical department for providing such a platform to show our skills. I would also like to extend a heartiest thanks to Mr. Tarak Das, the guide of the seminar and as well as our faculty advisor for guiding and correcting various documents of mine with attention and care. My deep sense of gratitude to my friends, family and my faculty members without whom this project would have been a distant reality. 2

- 4. INTRODUCTION Mind reading device – a technology which reflects the extreme enrichment of science. This technology ensures the fact of hacking our brain, breaching into our deepest thoughts and it may lead to the termination of our privacy. It possesses benefits as well as perils in its own numerous ways. In several countries clinical trials are running over in order to explain the human thoughts. This is a major leap toward reconstructing internal imagery. It is basically a co- ordination of human psychology and computer techniques. We are opening a window into the movies in our minds. 4
- 5. TECHNOLOGY What is Mind Reading? • Ability to attribute mental states to others from their behavior • To use that knowledge to guide our own actions and predict those of others • Machines representing computational model of mindreading to infer mental states of people. • Prior knowledge of how particular mental states are expressed through face in real time is required which is done with the help of a software NEVENVISION. 5
- 6. Why is Mind Reading? • To detect driver mental states such as drowsiness, distraction and anger. • To monitor and suggest improvement in human-human interaction. • Speech activates specific neurons as the brain works interpret the sounds as words."If you're reading text in a newspaper or book, you hear a voice in your own head," Brian Pasley told New Scientist magazine. 6
- 7. INSTRUMENTS • Electroencephalography(EEG) : It is a non-invasive method to record electrical activity of the brain along the scalp. Medical researchers use this to pick up electrical impulses from various parts of the brain. • Functional near-infrared spectroscopy (FNIRS) : Technology which measures the volume and oxygen level of the blood around the subject's brain. 7
- 8. • NASA has developed a computer program which can read silently spoken words. Just the slightest movement in the Voice box and tongue is enough to work. • Initially scientists trained the software program to recognize six words-including go, left, right and 10 numbers and the software correctly picked up the signals 92% of the time. • Futuristic headband that sends light into the tissues of the head where it is absorbed by active, blood-filled tissues. Then it measures how much light was not absorbed. Futuristic Headband SECRET DEVELOPMENTS 8
- 9. Facial electromyography : Facial electromyography is a technique used to measure the electrical activity of the facial muscles by amplifying the tiny electrical impulses that are generated by muscle fibers when they contract. A plot of skin resistance measured using GSR while playing a video game. Facial Impulse Detection TECHNIQUE 9

Electrodes distributed over the brain Credit: Adeen Flinker, UC Berkeley Using electroencephalogram (EEG) electrodes attached to the scalps of subjects, a University of Oregon team captured synchronized neural activity of short-term memory by monitoring these alpha rhythms. Electroencephalography 11

- 13. DISADVANTAGES • Individual brains differ • The initial tests may have been successful “doesn't mean it will scale up”. • Tapping Brains for Future Crimes • Risk of criminalizing the innocent resulting to “Brain Slavery” • Our society is not yet ready to accept this outcome of unacceptable violation of personal, mental privacy. 13
- 14. CONCLUSION • By using MRI imaging techniques to monitor people's brain activity, as they watched the footage, researcher’s from Berkeley University were able to create pictures from information processed by the brain. Although blurred, the reconstructed images bear a remarkable resemblance to the footage that the person is watching which could eventually move towards translating our memories onto screen. • Hence if we get 100% accuracy, these computers may find various applications in many fields, specially in electronics where we have very less time to react. • As every invention has its hurdles, so the “Mind Reading Device” is not an exception. This is a revolutionary invention, and will surely add a chapter to the benefits of human race. Initially reconstructed blurred image processed by brain 14
