INTRODUCTION:
Scientists have made a first step towards using computers to read people’s minds – but the scientists are the first to admit we have a long way to go.
The brain works by sending electrical signals between neuron s (aka brain cells). Measuring those signals would require sticking electrodes directly into t he brain, which Is very tricky because our brains are protected by our skulls . (Imagining techniques such as MRIs have given additional insights, but the y cannot measure the electrical activity.).
But, as they explain here , some people were going to get their skulls sliced open and electrodes put in anyway, and were kind enough to let some extra neuron scientists along for the ride.
People with epilepsy suffer electrical "storm s " in their brains, causing seizures. Sometimes, doctors will put a net of electrodes into the brains of patients with severe cases, so that they can see exactly where the storms are going on (and then treat the affected area of the brain).
Participants in the study were such patients. They let the neuron scientists peek into their brain activity when weren't having a seizure, but were instead listening to sounds. The computer brain activity could see how different words lit up different parts of the brain, and could build up these patterns.
Then here's the crazy part: Without knowing what words were being played, the computer could read the participants' brain activity and figure out what they were hearing.
Now, cutting open a healthy person's brain and putting electrodes in it will not become common practice any time soon. However, this research could become more main stream in the future. For people with disorders that prevent them from speaking, in the future it might be possible to hook them up with a computer that can say what they're trying to speak.
For those in long-term comas, it might be possible to see what brain activity is happening , and perhaps even communicate with those whose brains are working but whose bodies aren't. Mean while, as imagining technology such as MRI machines gives us a better peek into our brains without cutting into them, it may one day be possible to combine them with similar software and read people's mind s in a less invasive way.
Emotions, thoughts and desires, all the time through facial expressions, vocal nuances and gestures. This I s true even when they are in the ability to attribute mental states to others fromwith machines. their behavior and to use that knowledge to guide our own actions and predict those of others Is known as theory of mind or Existing they do oblivious to the user’s mental states and intentions. Take the initiative, like the now retired Microsoft Paperclip, they are often misguided and irrelevant, an d simply frustrate the user.
The mind-reading computer that could communicate with coma patients:
Ground breaking system can understand answers to simple questions from brain scans
• Participants were able to answer questions just by thinking about their answer.
• System can already distinguish between yes and no answers.
People express their mental states including emotions, thoughts and 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.
Canadian researchers have developing a mind-reading computer that could help communicate with people in a coma.
The University of Western Ontario researchers used neurons imaging to read human thoughts via brain activity when they are conveying specific ‘yes’ or ‘no’ answers.
The team say their research could lead to dramatic new ways of attempting to communicate with patients in a vegetative state.
The brain scans that reveal what we are thinking: The team found brain activity could reveal the answer to simple questions and could be used to communicate with patients in a coma.
Mind Reading was trialed with people from 4 years upwards and is suitable for an age range from 4 years old through to adult. There are six levels to choose from enabling each person to begin at their own level. Three different helpers are available to suit different tastes and ages.
WHAT IS MIND READING?
Vision and machine learning has developed mind-reading machines Using a digital video camera, the mind reading computers. System analyzes a person’s facial expressions in real time and infers Prior knowledge of how particular that person’s underlying mental state. Mental states are expressed in the face is combined with analysis of Software from facial expressions and head gestures occurring in real time N even vision identifies 24 feature points on the face and tracks them in .
The relationship between observable head and facial displays real time. And the corresponding hidden mental states over time are modeled using Dynamic Bayesian Networks.
A computational model of mind-reading
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. There are difficult challenges :
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 o r disagreeing, interested or bored, thinking or confused.
The mind-reading computer system may also be used to monitor and suggest improvements in human-human interaction. The Affective Computing Group at the MIT Media Laboratory is developing an emotional-social intelligence prosthesis that explores new technologies to augment and improve people’s social interactions and communication skill.

CONCLUSION
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 headbands 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.
Hence I f we get 100% accuracy these computers may find various applications in many fields of electronics where we have very less time to react.
Mind Reading is a unique reference work covering the entire spectrum of human emotions. Using the software you can explore over 412 emotions, seeing and hearing each one performed by six different people. There are also mini-stories to provide contexts. There are 2472 faces, 2472 voices at 2472 stories, all
about emotions. These voices will be with an English accent and use some vocabulary and cultural references specific to the U.K. but his is an important and invaluable new resource for
teaching emotions to children and adults within the autism spectrum - no autism software collection is complete without it. Mind Reading enables the user to study emotions and to learn the meanings of facial expressions and tone of voice, drawing on
comprehensive underlying audio-visual and text data base.
Mind Reading was developed by a team of scientists at Cambridge University led by Professor Simon Baron-Cohen. They combed the English language and found more than 1000 words that described .
Human emotions From this large number they eventually settled, after much testing, on 412 “emotion concepts” that they found to be distinct. This project was made possible by funding from The Shirley (Four) Mind Reading was trialed with people from 4 years upwards, and is suitable for an age range from 4 years old through to adult. There are six levels to choose from enabling each person to begin at their own level.
Three different helpers are available to suit. A computer means a device for which time related concept is very useful and consummating. This device can solve anything in fraction of seconds and by the growing technology now a day’s mind reading computer are also been developed that are capable of reading minds of humans too..
This is considered as the lab stunt. Human beings and especially people show their feelings and emotions by the way of facial expressions.
When w e users communicate with the system computers our mind creates an atmosphere on how we make contacts with others and this even harms our all over progress. So here an application is made where it can read the minds of the people.
Researchers are in process where the developers are trying to the reply the brain reading tasks successfully. These increasing difficulties of the task mean while the computer absorbs the light that the device.
This device called mind reading system gives the information the person’s mental condition as with the text ,with the Mouse.
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.
