Decoding silent reading from non-invasive EEG
Reading what someone is silently reading just from their brain waves
Researchers successfully decoded which words people were silently reading by analyzing their brain activity through EEG, correctly identifying words from a large vocabulary in the top 10 guesses over 60% of the time. The system improved with more data and showed no signs of hitting a ceiling, suggesting that with enough brain recordings, accuracy could keep climbing.
This is a step toward brain-computer interfaces that could help people who cannot speak or move — eventually allowing them to communicate their thoughts directly. The finding that the method kept improving with more data suggests that with denser recordings or better technology, we might eventually decode thoughts with practical accuracy. Understanding which brain signals carry word meaning also reveals how the brain processes language silently.
