MIT researchers have created a wearable device called AlterEgo that can recognize nonverbal prompts, essentially “reading your mind.” The system is made up of a device that loops around a user’s ear, follows their jawline, and attaches underneath their mouth, and a computer system. The wearable device has electrodes that pick up neuromuscular signals in your jaw and face that are triggered by internal verbalizations (aka saying words in your head) but can’t be seen by the human eye. These signals are then given to a machine learning system that analyzes the data, associating specific signals with words.
