A new type of Brain Computer Interface finally make a real NerveGear with full dive Virtual Reality a possibility. Ultrasound can completely non invasively write to the brain and thus create sensations in the brain without a direct implant.
Brain–machine interfaces (BMIs) are devices that can read brain activity and translate that activity to control an electronic device like a prosthetic arm or computer cursor. They promise to enable people with paralysis to move prosthetic devices with their thoughts.
Many BMIs require invasive surgeries to implant electrodes into the brain in order to read neural activity. However, in 2021, Caltech researchers developed a way to read brain activity using functional ultrasound (fUS), a much less invasive technique.
Now, a new study is a proof-of-concept that fUS technology can be the basis for an "online" BMI—one that reads brain activity, deciphers its meaning with decoders programmed with machine learning, and consequently controls a computer that can accurately predict movement with very minimal delay time.
