New Brain Implant that turns visualized letters into Text
Electrodes in the brain of a paralyzed man transformed his imagined handwriting into screen-type words. Ultimately, translation from brain to text can indicate ways to help disabled people use only their thinking to communicate
Brain Computer Interfaces or BCIs are able to restore movement in paralytic people and can help to treat psychiatric and neurological diseases. The next limit in BCIs may be such a low text message; typing still presents bioengineers with difficult challenges.
The artificial intelligence software was developed by a team at Stanford University together with electrodes in the brain and was able to read a man's thoughts, as he was asked to convert them to handwriting, with complete bone paralysis.
The new work of Kristina Shenoy's team focused on imagined handwriting to improve communication speed for the first time. And scientists hope that smartphone text rates at least will be reached. Their method permitted the 65 year old study subject to mentally type 90 characters a minute at the time of the research. For many senior writers who typically can write about 115 characters per minute on a phone, this rate is not far from average.
In 2007, the study participant was injured by the spinal cord and lost most of his motion beneath his neck. In 2016, the paper's co-senior author, Stanford neurosurgeon Jaimie Henderson, implanted into the brain of the patient two small BCI chips. Each chip had 100 neuronal activity sensory electrodes.
They were implanted in an area of the cortex of the motor that controls arms and hand movements to enable the researchers to profile patterns of written speech-related brain activity.
This is how the research was lead and we have to admit that this is a huge step forward on the Artificial Intelligence technology.
