Scientists at Stanford University developed a brain-embedded device that reads internal thoughts in real time without requiring physical speech. It decodes phrases by focusing on complex passwords to protect mental privacy. The technology reportedly deciphers 125,000 words with 74% accuracy from people with severe paralysis. Previous attempts were limited in vocabulary and required conscious effort from participants. This advancement allows for improved communication capabilities for individuals with conditions like amyotrophic lateral sclerosis and tetraplegia, showcasing the potential of invasive neural technologies in facilitating speech for those with severe impairments.
The device implanted in the brain captures imagined phrases in real-time, allowing people with paralysis to communicate without physically attempting to speak.
The brain reader activates only when participants visualize a complex password, ensuring user mental privacy and preventing accidental leakage of thoughts.
The results showed 74% accuracy in decoding internal monologues, dramatically increasing vocabulary possibilities to 125,000 words compared to previous methods.
This groundbreaking work marks the first real-time decoding of complete sentences using a large vocabulary from individuals with severe communication impairments.
