Brain typewriter
In future, there is an interesting possibility of being able to type out a book directly from the brain into the computer. There are many challenges with respect to studying the activity of the human brain, including very weak signals that need to be captured, converted and acted upon. The invention and improvement of Electroencephalography or EEG has made it possible to capture part of the signals and use them for some action. EEG systems are now being used for various purposes, one of them being to read the thoughts of bed-ridden patients and display them as text on a monitor for the comprehension of others. Brain gate technology owned by a company of the same name, has demonstrated that a brain implant system connected to robotic arms can perform actions for paralyzed humans. Experts predict that in future we may be able to control machines through thought alone and make them perform certain actions — taking us somewhere close to telekinesis. Dr Kalam had worked with one of his research scholars at Anna University to find an integrated solution using hardware, software and technology for near-normal functioning of mentally-challenged children. The research explored the possibility of implanting a bio chip in the brain to provide seamless data transfer between different parts of the brain. There is huge potential for research and business in this area.
