Jeff Han demos his breakthrough touchscreen. Health : Breakthrough: sensors that can convert thoughts into speech. A mind reading machine has edged closer to reality after scientists found a way of converting thoughts into words. Researchers were able to render brain signals into speech for the first time, relying on sensors attached to the brain surface. The breakthrough, which is up to 90 percent accurate, will be a boon for paralysed patients who cannot speak and could help read anyone’s thoughts ultimately, reports the Telegraph. “We were beside ourselves with excitement when it started working,” said Prof Bradley Greger, bioengineer at the Utah University who led the project. “It was just one of the moments when everything came together.
“We have been able to decode spoken words using only signals from the brain with a device that has promise for long-term use in paralysed patients who cannot speak. The breakthrough came when the team attached two button-sized grids of 16 tiny electrodes to an epileptic’s brain’s speech centres, says the journal of Neural Engineering.
