Alter Ego - Speak Without Words, Control With Your Mind

Developed by Arnav Kapur , this device is named Alter Ego. This is just like having an alternate self. Sounds amazing! Keep it reading.

Arnav Kapur is Delhi born and is studying  at Massachusetts Institute of Technology (MIT). He designed a device that can actually be used to communicate with machines and humans without opening their mouth or making physical gestures.

What is Alter Ego?

A human to machine or human to human interaction is facilitated by AlterEgo through "internal articulation of words," according to MIT, where Kapur is currently pursuing his master's and PhD in Media Arts and Sciences after moving to the country.

“It is a non-invasive, wearable, peripheral neural interface that allows humans to converse in natural language with machines, artificial intelligence (AI) assistants, services, and other people without any voice, simply by articulating words internally,” noted MIT.

How is communication carried out?

An interviewer is seen asking a number of questions to Kapur, who is wearing the device, in a popular video. The student, who was born in Delhi, answers each query nearly without speaking. The interviewer says, "You have the entire internet in your head," in response to this.

When a user's internal speech articulators are active during internal word articulation, the system records peripheral neural signals for this communication. As a result, the user can send information to and receive information from a computer or person without the sender taking any obvious action.

What locations will use the system?

According to MIT, the initiative is primarily intended for those with speech impairments, such as those who have ALS (amyotrophic lateral sclerosis) and MS (multiple sclerosis), among other illnesses. Beyond that, according to the institute, it has the ability to enhance intellect and capacities while smoothly integrating computing into people's daily life as their "second self" (thus the term AlterEgo).


Alter Ego's potential applications range from facilitating communication for individuals with speech impairments to enhancing telepathic interactions. This remarkable device marks a significant advancement in brain-computer interfaces, revolutionizing the way we interact with technology and opening doors to new possibilities in the future.
