AlterEgo is a wearable system that allows a user to silently converse with a computing device without any voice or discernible movements — thereby enabling the user to communicate with devices, AI assistants, applications, or other people in a silent, concealed, and seamless manner.

A human user could transmit queries, simply by vocalizing internally subtle internal movements and receive aural output through bone conduction without obstructing the user’s physical senses and without invading a user’s privacy.
Whenever you think of words, they’re silently, imperceptibly, transmitted to your mouth. More specifically, signals arrive at the muscles that control your mouth. It’s 92 percent accurate probably better than your average autocorrect, about the same as Siri or Alexa.

AlterEgo aims to combine humans and computers—such that computing, the internet, and AI would weave into human personality as a “second self” and augment human cognition and abilities. Lead researcher: Arnav Kapur, Fluid Interfaces group.
