​Yesterday you watched a video about the new technology which gives people hope. Here’s an article to dig a bit deeper. It might be difficult for the beginners but it’s worth reading. Key vocabulary for reading: 🔴Eye tracking -the process of measuring the motion of an eye; 🔴spell sth out - to say or write the letters of a word in the correct order; 🔴consent - permission for something to happen or agreement to do something On meeting the man in February 2018, a scientist Chaudhary tried to automate the communication system that the family was already using. The team connected an eye-tracking device to computer software that would read out colors and row numbers, allowing the man to select letters one at a time using his eye movements to spell out words. But as the man increasingly lost control over his eye movements, he became less able to communicate using that device, too. “We proposed implanting [an electrode],” says Chaudhary. Tiny electrodes can be implanted in the brain to record the electrical activity of brain cells directly. The procedure—which tends to involve drilling a hole in the skull and cutting away the brain’s protective layers—comes with a small risk of infection and damage to the brain. But there was no other choice. His wife and sister also gave their consent.
