Islamabad, Feb 11: Meta has introduced a groundbreaking system that could make “mind typing” a reality, allowing brain activity to be translated into text. This advanced system, developed by Meta’s AI and neuroscience teams, represents a significant step toward revolutionizing communication. However, there are still notable hurdles to overcome before this technology becomes practical for everyday use.
The current technology relies on a hefty half-ton machine, priced at a staggering $2 million, making it far from portable. Users must remain perfectly still during the process, as even minor head movements can disrupt the results. The system works by interpreting magnetic signals from the brain using magnetoencephalography (MEG), a technique that captures brain activity through magnetic fields without requiring any implanted electrodes or wearable sensors.

In the experimental setup, volunteers sit inside a large MEG scanner, which resembles a giant hairdryer, while mentally typing sentences. The scanner records signals from brain neurons, and an AI model, named Brain2Qwerty, is trained to match these signals to corresponding letters. After significant training, the system has shown the ability to predict and reconstruct words with up to 80% accuracy.
While the technology is promising, it faces significant challenges. For one, the MEG scanner must be placed in a shielded room to avoid interference from the Earth’s magnetic field, which is far stronger than the brain’s signals. Additionally, even slight movements can scramble the data, making it difficult to produce consistent results.
Despite these limitations, this innovation could have transformative potential for individuals with brain injuries, neurological disorders, or conditions like paralysis, offering them new ways to communicate. Unlike brain implants, such as those being developed by companies like Neuralink, Meta’s non-invasive approach eliminates the risks associated with surgery, positioning it as a safer, long-term solution.
While the technology is far from ready for widespread use, it hints at a future where brain-computer interfaces could be as portable as today’s smartphones. Meta’s progress is a fascinating glimpse into the future of mind-controlled communication.
