    Mind reading computer ppt Mind reading computer ppt Presentation Transcript

    •  Introduction What is Mind Reading? Why Mind Reading? How does it Work? Advantages and uses Disadvantages and Problems Conclusion
    •  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.
    •  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. Prior Knowledge of how particular mental states are expressed in the face is combined with analysis of facial expression and head gestures occurring in real time. 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.
    •  The Mind reading Computer system Present information about your mental state as easily as a keyboard and mouse present a text and 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 and learning system.
    •  The mind-reading computer system may also be used to monitor and suggestimprovements in human-human interaction.The Affective Computing Group at the MIT Media Laboratory is developing anemotional-social intelligence prosthesis that explores new technologies to augment andimprove people’s social interactions and communication skills.To implement this system in cars to detect driver mental states such asdrowsiness, distraction and anger.
    •  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.
    •  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”.
    •  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.
    •  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.
    • Facial ElectromyographyIt is used to measure electrical activity ofthe facial Muscles. Muscles used are”corruguator supercilii muscle” and others. Galvanic Skin ResponseIt is a measure of Skin conductivity, Whichis dependent on how moist the skin is.
    • Blood Volume PulseIt is measured by process calledphotoplethysmography.It produce a graph indicating bloodflow through the extremities.
    •  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.
    •  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
    •  Tufts University researchers have begun a three-year research project which, if successful, will allow computers to respond to the brain activity of the computers 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 its interface and functions to each individual.
