Alterego is a wearable device developed by a team originating from MIT's Media Lab that enables users to communicate silently by detecting internal speech signals. The technology works by capturing neuromuscular signals generated when a person silently speaks words in their mind without vocalizing them. These signals are then interpreted by the device to allow communication without sound, resembling a form of telepathy.
The device has practical applications such as facilitating private conversations, enabling real-time translation, and offering hands-free control over digital assistants and AI systems. Alterego is still in the prototype stage but demonstrates a promising approach to silent communication, potentially transforming how people interact with technology and with one another in various settings.
