Earlier versions relied on people pointing to and clicking letters on a virtual keyboard, but they could only write about 40 characters per minute. It has taken the scientists several years to fine tune their technology so it can capture and interpret different brain signals.

Most recently, a clinical trial participant used the device to write text on a computer just by thinking about the movements involved in handwriting. The hope is that such a system may one help restore communication and movement in people with paralysis due to injury or illness. Those signals can then be used to control robotic prostheses, computers or other devices. “Frank’s demonstration of fast, accurate neural decoding of handwriting marks an exciting new chapter in the development of clinically useful neurotechnologies.” Designing a faster way to communicate As part of the BrainGate clinical trial, researchers are using tiny electrode arrays to record signals from the motor cortex of the brain. “An important mission of our BrainGate consortium research is to restore rapid, intuitive communication for people with severe speech or motor impairments,” says Dr. The participant testing the hardware was able to type up to 90 characters a minute, more than double the previous record. More importantly, the technology could restore the ability to communicate for people who suffer from paralysis following an accident or other condition. Like something out of science fiction, just thinking about the hand movements which produce written letters is enough for the tech to make it a reality. The implant captures brain signals associated with handwriting and turns them into text on a computer screen in real time.
Could the future of office work be sitting inside a microchip smaller than a dime? Researchers from Brown University say a chip inserted into the brain can allow people to type without the need for a keyboard.
