While mind-reading interfaces that convert thoughts to text sound like a dystopian sci-fi plot that could go horribly wrong disturbingly fast, the reality may not be so far away — or as fallible, either.

When you first hear “thought to text,” your knee-jerk response might be, “Uhh, no way. What if I have an intrusive thought that I don’t really mean to send? Or an impulse to text someone I know I shouldn’t?” But the most recent brain-computer face interface studies don’t rely on decoding your internal monologue or raw thoughts.

Rather, researchers have programmed a brain-computer interface that decodes “attempted handwriting movements” from motor cortex activity. This technology allows people who have been paralyzed for years to imagine handwriting and translate that into texting at speeds of 90 characters per minute with 94.1 percent accuracy, which is comparable to average smartphone typing speeds.

Furthermore, that accuracy climbs to 99 percent with general-purpose autocorrect.
