Facebook has announced a breakthrough in its plan to create a device that allows people to type just by thinking.
According to BBC, it has funded a study that developed machine‑learning algorithms capable of turning brain activity into speech.
It worked on epilepsy patients who had already had recording electrodes placed on their brains to asses the origins of their seizures, ahead of surgery.

Facebook hopes it will pave the way for a "fully non‑invasive, wearable device" that can process 100 words per minute.
