“Using only a sensor-filled helmet combined with artificial intelligence, a team of scientists has announced they can turn a person’s thoughts into written words.

In the study, participants read passages of text while wearing a cap that recorded electrical brain activity through their scalp. These electroencephalogram recordings were then converted into text using an AI model called DeWave.

Chin-Teng Lin at the University of Technology Sydney, Australia, says the technology is non-invasive, relatively inexpensive and easily transportable.

While the system is far from perfect, with an accuracy of approximately 40 per cent, Lin says more recent data currently being peer-reviewed shows an improved accuracy exceeding 60 per cent.”
