Technology To Communicate Through Thought

US Army has granted to develop such an e mail or voice mail system which could only work on thought. They demanded that it should be designed so that there should be no need to dial phone, speak word or type to send this mail. 
This technology has been given name of synthetic technology. It will be able to read electrical activity going on in mind of any person. The technology of electroencephalograph (EEG) will be used for that. Such type of technology has also been introduced earlier, which is being used to control video games. This idea to communicate through thought is not a new concept. In 1960, a scientist used this concept in his experiment. He linked EEG with his head and tried to compose Morse code messages through alpha waves of his mind.
The research is going on in three American universities which include University of California, Irvine, Carnegie Mellon University and University of Maryland. This is a heavy project. Army is granting these universities for its development. They demanded that the system should be capable to compose message through thoughts. Secondly it also should have power to send it to other individuals or devices. Recipients should also be able to read this information in voice or text form.
D’Zmura said that this thought-based communication system will get more popularity in a civil sector as compared to military. It is expected that it will greatly help in medical field especially for the patients of Lou Gehrig. When that disease gets severe condition, the patient’s muscles get weaker whereas his thoughts work accurately. For these patients this synthetic telepathy will help them in communicating.
Three types of technologies are being used in its development which includes EEG, functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG). Each of the technology is having its own functionalities. Among them EEG is a cheaper, lighter and fast technology. These technologies will be mapped with each other. This arrangement will enable computer to perform its function. When any part of the brain lights up on EEG, this system will understand which word or phrase the mind is trying to say.
However there are also some technical problems in it which should be resolved before deploying it for practical use. Everything is possible in science world; 40 or 50 years ago no body could think about technologies we are using now. Similarly, we can hope that after some years all what we are thinking about thought technology would be available in market.
