The ‘near-telepathic’ device that puts AI in your head

A wearable device offers a similar experience to brain-computer interfaces without the invasive implants or the privacy concerns that come along with mind-reading. The ‘AlterEgo’ device detects electrical signals in the muscles used to formulate speech that are sent by the brain when you silently mouth or even just internally articulate words. Its makers say it could be used by people who have issues with speaking, or to interact with voice-controlled applications without having to talk out loud.
