Meta’s AI researchers have developed a system that can interpret brain signals to determine what keys a person is pressing while typing, achieving an accuracy of up to 80%. This breakthrough, however, comes with significant limitations: the technology requires a massive, $2 million magnetoencephalography scanner, which must be housed in a shielded room to block Earth’s magnetic field. The system, named Brain2Qwerty, was tested on 35 volunteers who spent around 20 hours each typing phrases. Despite its impressive accuracy, the average error rate was about 32%, meaning nearly one in three letters was incorrect. This research, conducted at the Basque Center on Cognition, Brain, and Language in Spain, isn’t aimed at creating consumer products but rather at understanding the principles of human intelligence to enhance AI development.
