Technology really find ways to give people advancement that changed lives and the world as a whole.
Researchers from a prestigious university in US gave patient with severe limb weakness the ability to type 39 correct characters per minute, outperforming any other platform. The new advancement was made possible through a brain-computer interface or BCI.
It was a breakthrough systems that let paralyzed people the ability to walk to others that restore sight in the blind, major advances are being made in the field of BCIs.
Stanford University’s researchers have built a new brain-computer interface (BCI) that allows paralyzed people to type with their brains at a rate faster than was previously possible.
Proponents worked with three participants with severe limb weakness, two due to Lou Gehrig’s disease and one with limited movement due to a spinal cord injury. All three participants had electrode arrays embedded in their brains to record signals from the motor cortex, which controls muscle movement.
A cable then transmitted the brain signals to a computer, and they were then translated by algorithms into point-and-click commands that prompted a cursor to move over letters. Basically, participants were able to move the cursor by imagining their own hand movements.
The subjects were able to achieve BCI results that outperformed any available platform today.
In fact, one patient was able to type 39 correct characters per minute, which is around eight words per minute, proving that BCIs have the potential to enhance communication among people with impaired movement. It should be noted that these typing-rates were achieved without the use of automatic word-completion.
“The performance is really exciting. We’re achieving communication rates that many people with arm and hand paralysis would find useful. That’s a critical step for making devices that could be suitable for real-world use,” says Chethan Pandarinath, one of the authors of the paper, told Stanford.
