Breakthrough tech defines 'a new kind of writing,' researchers say.
A major advancement in the field of brain-computer interface , announced in May, allowed a paralyzed man to imagine writing and have the words translated to text.
Led by Frank Willett, a research scientist with the Braingate research consortium, the new system doubles the speed of previous thought-to-text BCI tools, which had subjects look at a screen and mentally “point and click” — as if using a cursor — rather than simply imagining writing the letter. In the late 1960s, BCI research was first conducted on monkeys; human trials began in the early 2000s. The current research involves placing tiny electric arrays directly into the motor cortex of the subject, which records neuron activity. Working with tech that previously controlled the movement of robotic arms , researchers were able to use very quick, tiny movements, separated from each other, to create a spelling device.
