Vibrotactile feedback

Definition

Vibrotactile feedback refers to the use of vibrations to convey information through the sense of touch. This technology is essential in prosthetic control, as it provides users with sensory input that mimics the natural feedback one would receive from biological limbs, enhancing the user's awareness of their prosthetic and improving control.
