MENTAL TELEPATHIST MACHINE

CONCEPT OF MIND READING
Existing human-computer interfaces are mind-blind — oblivious to the user’s mental states and intentions. A computer may wait indefinitely for input from a user who is no longer there, or decide to do irrelevant tasks while a user is frantically working towards an imminent deadline. As a result, existing computer technologies often frustrate the user, have little persuasive power and cannot initiate interactions with the user. Even if they do take the initiative, like the now retired Microsoft Paperclip, they are often misguided and irrelevant, and simply frustrate the user. With the increasing complexity of computer technologies and the ubiquity of mobile and wearable devices, there is a need for machines that are aware of the user’s mental state and that adaptively respond to these mental states.
INTRODUCTION
A device that can see the "mind's eye" to work out what someone is looking at, thinking of, oring about, is now a possibility.
A quantum theory of dreams?
Illusions that will twist your mind
Hypnotism does change the brain
Science fiction writers have long speculated about the implications of mind reading, with perhaps the most lurid application being to study the brain of a newly-deceased murder victim to work out the last thing that person saw.
Although that will likely remain in the realm of fiction, an American team led by Prof Jack Gallant today announces it has taken an important step towards a device that can 'read' the living brain and tap into the state of another person's conscious experience of vision.
His team at the University of California, Berkeley, reports in the journal Nature a major advance in working out how we see by deducing the relationship between natural images and the patterns of brain activity in the visual areas at the back of the brain.
ADVANCEMENT IN THIS FIELD
(Mind-Reading Machine Almost A Reality)
A group of scientists at the University of Utah in Salt Lake City, recently revealed that they may be really close to perfecting a machine that helps translate brain signals into words, a significant breakthrough that will allow severely paralyzed people to be able to communicate their thoughts clearly.
CONCLUSION
Scientists at the University of Utah have moved one step closer to using electrodes to read someone's mind.No need to think nefariously. It's all for a good purpose - helping people who are paralyzed speak and operate machines. In the experiment, doctors implanted tiny electrodes on the brain of an epileptic with severe seizures. The man already had part of his skull removed so doctors could treat his epilepsy. According to a statement: "Scientists recorded brain signals as the patient repeatedly read each of 10 words that might be useful to a paralyzed person: yes, no, hot, cold, hungry, thirsty, hello, goodbye, more and less."
"Later, they tried figuring out which brain signals represented each of the 10 words. When they compared any two brain signals - such as those generated when the man said the words 'yes' and 'no' - they were able to distinguish brain signals for each word 76 percent to 90 percent of the time."But the doctors ran into trouble when they looked at all 10 signals simultaneously. Their accuracy dropped to as low as 28 percent.
"This is proof of concept," says Bradley Greger, an assistant professor of bioengineering at the university. "We've proven these signals can tell you what the person is saying well above chance. But we need to be able to do more words with more accuracy before it is something a patient really might find useful."The hope, they say, is to one day help patients who are "locked in" and have very few, if any, ways to communicate. That includes patients with advanced-stage Lou Gehrig's disease. Part of the cool geek factor here is that scientists used a new kind of electrode, called microECoGs. It sits on top of the brain, but doesn't penetrate. That makes it safer to place electrodes on sensitive areas. Doctors are already using them to help severe epileptics.
