New neuroprosthesis allows to translate thoughts into printed text

Neurophysiologists from the United States have created a new “brain-computer” interface capable of translating human thoughts into printed text. As writes edition of Nature, the new neuroprosthesis has allowed the paralyzed invalid to print about 90 characters per minute by thought.

According to Francis Willett of Stanford University, the new system demonstrates record-breaking typing speed. This is achieved because the neural interface directly reads the letters a person draws in his or her mind. “As it turns out, each symbol corresponds to a unique pattern of brain activity, which allows the system to quickly recognize thoughts and translate them into typed text almost without error,” the scientist explained.

In recent decades, bioengineers and neurophysiologists have developed many different cyberprostheses, as well as artificial limbs and sensory organs, which are connected to the brain through so-called neurointerfaces. In 2012, for example, researchers at Brown University and Stanford University were able to connect a robotic arm to the brain of a woman suffering from paralysis, and she was eventually able to drink her own coffee.

“We focused on using neural interfaces to create more convenient forms of communication. Transforming thoughts into digital information is a very promising area that could change the way people interact with computers,” Willett says.
