A revolution is unfolding in the world of artificial intelligence, and experts consider the development of contactless interfaces to be one of its promising directions, which could become the basis for new ways of human-computer interaction. The company Meta has developed an innovative non-invasive neurointerface that allows you to enter text using thoughts.

The development is based on the use of a magnetoencephalographic scanner that records the electrical activity of the brain. By analyzing brain signals, the system is able to determine which characters the user is trying to type. During an experiment involving 35 volunteers, an algorithm based on a deep neural network was able to achieve 80% accuracy in recognizing letters.

The technology is still far from mass adoption due to its hardware limitations and the high cost of equipment. Additional difficulties are associated with high sensitivity to head movements, which affects the correct recognition of signals. Despite the achieved accuracy of 80%, the average error was about 32%, which makes the technology пока непригодной для практического использования. Moreover, the technology requires specially equipped rooms with protection from external magnetic fields.

Back in 2017, Mark Zuckerberg announced the development of a technology that allows you to "type text directly from the brain". The company's initial plan was to create a compact device - for example, a hat or bandage - that could read brain signals and convert them into text without implanting implants. However, the project encountered technical limitations, and four years later, the development of its consumer version was abandoned.

Despite this, Meta continued to fund research in the field of neuroscience. And although the new technology developed by its specialists remains exclusively laboratory, the company considers it a strategic direction that can deepen the understanding of human thinking and contribute to the development of artificial intelligence.
