TELEGRAPH– Unlike current brain-controlled computers, which require users to imagine
making physical movements to control a cursor on a screen, the new
technology will be capable of directly interpreting words as they are
thought.
Intel’s scientists are creating detailed maps of the activity in the brain for individual words which can then be matched against the brain activity of someone using the computer, allowing the machine to determine the word they are thinking.
Preliminary tests of the system have shown that the computer can work out words by looking at similar brain patterns and looking for key differences that suggest what the word might be.
Dean Pomerleau, a senior researcher at Intel Laboratories, said that currently, the devices required to get sufficient detail of brain activity were bulky, expensive magnetic resonance scanners, like those used in hospitals.
But he said work was under way to produce smaller pieces of equipment that can be worn as headsets and that can produce the same level of detail.
