Pattern recognition control

Definition

Pattern recognition control is a method used in prosthetic systems that interprets neural signals from the brain or peripheral nerves to execute specific movements. This approach involves recognizing the unique patterns of neural activity associated with different intended actions, allowing for more intuitive and precise control of prosthetic devices. By leveraging these patterns, users can achieve smoother and more naturalistic movements, greatly enhancing the usability of prosthetics.
