A computer can, in a very real sense, read human minds. Although the dot’s gyrations are directed by a computer, the machine was only carrying out the orders of the test subject .The computer mind-reading technique is far more than a laboratory stunt. Though computers can solve extraordinarily complex problems with incredible speed , the information they digest is fed to them by such slow, cumbersome tools as typewriter keyboards or punched tapes. People express their mental states, including emotions, thoughts, and desires, all the time through facial expressions, vocal nuances and gestures a computer can, read it very real sense. Although the dot’s gyrations are directed by a computer, the machine was only carrying out the orders of the test facial expression. The computer mind- reading technique is far more than a laboratory stunt. The key to his scheme: the electroencephalograph, a device used by medical researchers to pick up electrical currents from various parts of the brain. If we could learn to identify brain waves generated by specific thoughts or commands, we might be able to teach the same skill to a computer. The machine might even be able to react to those commands by, say, moving a dot across a TV screen. So far the S.R.I, computer has been taught to recognize seven different commands — up, down, left, right, slow, fast and stop .these review is focus mainly on mind reading and use this technic for handicapped person by using futurestic band.
